Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.

Texas voters OK $3 billion for new dementia research institute

state funding

Texas voters on Nov. 4 overwhelmingly approved a ballot measure that provides $3 billion in state funding over a 10-year span for the newly established Dementia Prevention and Research Institute of Texas (DPRIT).

Thanks to the passage of Proposition 14, Texas now boasts the country’s largest state-funded initiative dedicated to dementia research and prevention, according to the Alzheimer’s Association. Up to $300 million in grants will be awarded during the 10-year funding period.

“This is a transformative moment for Texas and for the fight against Alzheimer’s and all other dementia,” said Joanne Pike, president and CEO of the Alzheimer’s Association. “Texans have chosen to invest in hope, innovation, and solutions for the millions of families affected by these devastating diseases. With the passage of Proposition 14, Texas is now poised to lead the nation in dementia research and prevention.”

The association says DPRIT will drive scientific breakthroughs, attract top-notch dementia researchers to Texas, and generate thousands of jobs statewide.

An estimated 460,000 Texans are living with dementia, the association says, and more than one million caregivers support them.

DPRIT is modeled after the Cancer Prevention and Research Institute of Texas (CPRIT). Since 2008, the state agency has awarded nearly $4 billion in grants to research organizations for cancer-related academic research, prevention programs, and product development.

An analysis by the McKinsey Health Institute found that investing in brain health initiatives like DPRIT could boost Texas’ GDP by $260 billion. Much of that GDP bump could benefit the Houston area, which is home to dementia-focused organizations such as UTHealth Houston Neurosciences, Baylor College of Medicine’s Center for Alzheimer’s and Neurodegenerative Diseases, the University of Texas Medical Branch at Galveston’s Collaborative Alzheimer’s Disease and Memory Disorders Program, and the Houston Methodist Research Institute’s John M. O’Quinn Foundation Neurodegenerative Disorders Laboratory.

The Greater Houston Partnership says DPRIT holds the potential “to elevate Texas — particularly Houston — as a hub for brain health research.”

State Sen. Joan Huffman, a Houston Republican, is one of DPRIT’s champions. She sponsored legislation this year to create the institute and ask Texas voters to approve the $3 billion in funding.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said in May. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our health care community.”

Houston medical institutions launch $6M kidney research incubator

NIH funding

Institutions within Houston’s Texas Medical Center have launched the Houston Area Incubator for Kidney, Urologic and Hematologic Research Training (HAI-KUH) program. The incubator will be backed by $6.25 million over five years from the National Institutes of Health and aims to create a training pipeline for researchers.

HAI-KUH will include 58 investigators from Baylor College of Medicine, Texas Children’s Hospital, the University of Texas Health Science Center at Houston, University of Houston, Houston Methodist Research Institute, MD Anderson Cancer Center, Rice University and Texas A&M University Institute of Biosciences and Technology. The program will fund six predoctoral students and six postdoctoral associates. Trainees will receive support in scientific research, professional development and networking.

According to the organizations, Houston has a high burden of kidney diseases, hypertension, sickle cell disease and other nonmalignant hematologic conditions. HAI-KUH will work to improve the health of patients by building a strong scientific workforce that leverages the team's biomedical research resources to develop research skills of students and trainees and prepare them for sustained and impactful careers. The funding comes through the National Institute of Diabetes and Digestive and Kidney Diseases.

The principal investigators of the project include Dr. Alison Bertuch, professor of pediatric oncology and molecular and human genetics at BCM; Peter Doris, professor and director of the Institute of Molecular Medicine Center for Human Genetics at UT Health; and Margaret Goodell, professor and chair of the Department of Molecular and Cellular Biology at Baylor.

“This new award provides unique collaborative training experiences that extend beyond the outstanding kidney, urology, and hematology research going on in the Texas Medical Center,” Doris said in a news release. “In conceiving this award, the National Institute of Diabetes and Digestive and Kidney Diseases envisioned trainee development across the full spectrum of skills required for professional success.”

Jeffrey Rimer, a professor of Chemical Engineering, is a core investigator on the project and program director at UH. Rimer is known for his breakthroughs in using innovative methods in control crystals to help treat malaria and kidney stones. Other co-investigators include Dr. Wolfgang Winkelmeyer (Baylor), Oleh Pochynyuk (UTHealth), Dr. Rose Khavari (Houston Methodist) and Pamela Wenzel (UT Health).

“This new NIH-sponsored training program will enable us to recruit talented students and postdocs to work on these challenging areas of research,” Rimer added in a release.

CPRIT grants $22M to bring top cancer researchers to Houston

fresh funding

Several prominent cancer researchers are coming to the Houston area thanks to $22 million in grants recently awarded by the Cancer Prevention and Research Institute of Texas (CPRIT).

The biggest CPRIT recruitment grant — $6 million — went to genetics researcher Jean Gautier. Gautier, a professor of genetics and development at Columbia University’s Institute for Cancer Genetics, is joining the University of Texas MD Anderson Cancer Center to continue his research.

The website for Gautier’s lab at Columbia provides this explanation of his research:

“The main objective of our research is to better understand the molecular mechanisms responsible for the maintenance of genome stability. These controls are lost in cancer, which is characterized by genomic instability.”

Aside from his work as a professor, Gautier is co-leader of the Herbert Irving Comprehensive Cancer Center’s Cancer Genomics and Epigenomics Program at Columbia.

Other recipients of CPRIT recruitment grants include:

$2 million to recruit Xun Sun from the Scripps Research Institute to the University of Texas Medical Branch at Galveston.
$2 million to recruit Mingqi Han from the University of California, Los Angeles to MD Anderson.
$2 million to recruit Matthew Jones from Stanford University to MD Anderson.
$2 million to recruit Linna An from the University of Washington to Rice University.
$2 million to recruit Alissa Greenwald from the Weizmann Institute of Science to MD Anderson.
$2 million to recruit Niladri Sinha from Johns Hopkins University to the Baylor College of Medicine.
$2 million for Luigi Perelli to stay at MD Anderson so he can be put on a tenure track and set up a research lab.
$2 million for Benjamin Schrank to stay at MD Anderson so he can be put on a tenure track and set up a research lab.

Over $20.2 million in academic research grants were awarded to researchers at:

Baylor College of Medicine
Houston Methodist Research Institute
Rice University
Texas Southern University
University of Houston
University of Texas Health Science Center at Houston
University of Texas MD Anderson Cancer Center
University of Texas Medical Branch at Galveston

In addition, nearly $4.45 million in cancer prevention grants were awarded to one researcher at the University of Texas Medical Branch at Galveston and another at Texas Southern University.

Also, five Houston businesses benefited from CPRIT grants for product development research:

Allterum Therapeutics, $2,999,996
CTMC, $1,342,178
Instapath, $900,000
Prana Surgical, $900,000
InformAI, $465,188

“Texas is a national leader in the fight against cancer,” said Kristen Pauling Doyle, CPRIT’s CEO. “We can measure the return on investment from CPRIT grants … not only in the economic benefits flowing from increased financial activity and jobs in the state, but more importantly in the cancers avoided, detected early, and treated successfully. Thanks to the Legislature’s vision, this commitment is saving lives.”

Overall, CPRIT approved 61 grants totaling more than $93 million in this recent round of funding.

Houston neurodegenerative company expands research collaboration with Houston Methodist

growing biz

A clinical-stage Houston biotech company has expanded its collaboration with Houston Methodist Research Institute, or HMRI.

Coya Therapeutics is already sufficiently established to be publicly traded since late 2022, but there’s always room to grow. With the help of a new sponsored research agreement, Coya will work on multiple initiatives. Coya is led by co-founder and CEO Howard Berman, who was inspired by his father’s dementia diagnosis.

"I was interested in what I could do for my dad," Berman said on the Houston Innovators Podcast, explaining that he met with renowned Houston Methodist researcher and neurologist, Dr. Stanley Appel, who showed him that he was not only working on treatments that could help Berman’s now-deceased father, but that he’d been able to stop the progression of ALS.

The treatments that Coya is developing are targeted at using regulatory T cells (Tregs) to fight both system inflammation and neuroinflammation. That means that maladies in their sights include neurodegenerative, metabolic, and autoimmune diseases, all of which may be caused by dysfunctional Tregs. Specifically, those might include currently hard-to-fight battles like ALS, Alzheimer’s disease, frontotemporal dementia, and Parkinson’s disease.

With the expanded partnership, "the development and production of exosomes from patients’ regulatory T cells will be funded by the Johnson Center for Cellular Therapeutics with participation of the SRA," according to a news release.

Coya’s therapeutic platforms include Treg-enhancing biologics, Treg-derived exosomes, and autologous Treg cell therapy. The new joint effort with HMRI will focus primarily on advancing the exosome technology in the direction of a first-in-human clinical study that will explore novel, synergistic drug combinations with one of Coya's lead candidates, COYA 301. Biologic combinations form the basis of Coya’s approach in addressing the complex pathophysiology of diseases, but they also create future opportunities for strategic collaborations.

COYA 301 is the company’s proprietary investigational low-dose interleukin-2 (IL-2). It’s designed to enhance the anti-inflammatory function of Tregs and is administered subcutaneously.

Hopefully, it will follow the success of COYA 302, which is not yet approved by the FDA or any other agency, but is well on its way, thanks to results from a proof-of-concept, open-label clinical study that evaluated commercially available LD IL-2 and CTLA-4 Ig in a small cohort of patients with ALS, conducted at the HMRI. During the 48-week treatment period, patients tolerated the treatment well and showed significant amelioration in the progression of the disease.

As Coya advances its therapies, ALS and other neurodegenerative ailments could one day be far less doom-filled diagnoses.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.

Houston e-commerce giant Cart.com launches government-focused subsidiary

government branch

Houston e-commerce and logistics unicorn Cart.com has launched a new subsidiary.

Cart Government Solutions (CGS), which was announced earlier this week, will provide supply chain and logistics services and software for the federal and state government sectors. The new subsidiary will be headquartered in Washington, D.C., and operate out of about 6 million square feet of secure warehouse space across 14 U.S. facilities, according to a news release from Cart.com. It will support both domestic and overseas logistics.

Industry veteran Gregg Zegras will lead the new entity as president. Zegras previously served as Cart.com's chief revenue officer, according to LinkedIn. Before that, he served as president of Connecticut-based Pitney Bowes Global eCommerce, a digital shipping solutions company.

Remington Tonar, Cart.com's co-founder, will serve as CGS's chief innovation officer.

“Government agencies face procurement and logistics challenges that many commercial platforms simply weren’t built to solve,” Zegras said in the news release. “Cart Government Solutions exists to change that. We’re combining the speed and innovation of a technology company with the compliance rigor, security, and operational depth that federal and state customers require, and we’re doing it with a team that has spent careers working alongside and inside these agencies.”

According to the company, CGS will focus on meeting compliance and security requirements in the public sector. Some of the services the new entity will offer include:

Inventory management
Cold-chain and specialty storage for pharmaceuticals, medical devices and regulated goods
Enterprise-grade supply chain software
Government-compliant webstores and online ordering portals
Cybersecurity operations

Cart.com has been serving the public sector since 2022, when the company began distributing COVID-19 health supplies nationwide, according to the news release. Through that pandemic-era contract, the company reports it moved more than 725 million units, with an average of under two days per shipment.

Cart.com was founded in Houston in 2020, though it briefly moved its headquarters to Austin. The company reached unicorn status with its $60 million Series C raise in 2023. It most recently raised $180 million in growth capital from private equity firm Springcoast Partners in March, which put the startup over the $1 billion in fundraising mark in just six years.

At the time, Cart.com said it planned to scale its logistics network, expand AI capabilities and develop workflow automation tools.

Houston-based KBR Inc. also recently launched a government services spinoff. Read more here.

2 Houston universities named best colleges of 2027 by Princeton Review

A-Plus Ratings

Back-to-school season has returned in full force, and that means it's time for college rankings. Two Houston universities in particular are being hailed as the top of the class for 2027.

The high caliber schools — Rice University and University of Houston — earned new acclaim in The Princeton Review's ranking of the "Best 392 Colleges" for 2027.

The Princeton Review's 35th annual "Best Colleges" rankings are determined by a survey of 172,000 current college students that gave "candid feedback" about their schools and their experiences. The flagship guide does not rank the schools overall, but it does rank them across 50 different categories, including best-run colleges, best quality of life, happiest students, best athletic facilities, among others.

In all, 14 Texas institutions were highlighted in the overall list of the 392 best colleges.

Schools don't pay to be included in the guide, but The Princeton Review clarified that schools could pay for a "featured" designation. No Houston university paid to be featured in this year's guide. Trinity University in San Antonio and Southwestern University, a private school in the Austin suburb Georgetown, were the only two Texas schools that paid to be "featured."

Rice and UH have been on a winning streak in separate reports of the best universities worldwide, best graduate schools, and best online degree programs.

In addition to being included in the overall list, Rice was highlighted as one of the Best Value Colleges, Colleges That Create Futures, and it earned high marks in Princeton Review's Mental Health Honor Roll 2026. The home of the Rice Owls also starred in the regional Best Southwest list that contained 41 universities across Arizona, Colorado, New Mexico, Oklahoma, and Texas.

"Rice University stands out as a leading research university where academic diversity and a wide array of interdisciplinary institutes and centers make it easy for students to explore multiple areas of interest," the school's profile says. "At Rice, 'knowledge isn’t siloed — students are constantly crossing disciplines and interests in ways that feel natural rather than exceptional.'"

Rice earned the following rankings on 14 other lists:

No. 1 – Lots of Race/Class Interaction
No. 3 – Best College Newspaper
No. 9 – Friendliest Students
No. 11 – Best Quality of Life
No. 13 – Great Financial Aid
No. 14 – Top 50 Best Value Private Colleges
No. 17 – Their Students Love These Colleges

No. 19 – Best College Dorms
No. 21 – Students Study the Most
No. 24 – Best Campus Food
No. 24 – Best College Radio Station
No. 24 – Best-Run colleges

The University of Houston also appeared in the Best Southwest, Best Value Colleges, and Colleges That Create Futures lists, and it was named a top Green College, which examined schools that "share superb sustainability practices, a strong foundation in sustainability education, and a healthy quality of life for students on campus

UH earned five more accolades:

No. 1 – Top 50 Undergraduate Schools for Entrepreneurship Studies
No. 1 – Top Undergraduate Schools for Entrepreneurship Studies in the Southwest
No. 8 – Most Politically Moderate Students
No. 15 – Financial Aid Not So Great
No. 42 – Top 50 Best Value Public Colleges

In the school's profile, students say they had an overall positive experience thanks to UH's excellent academic offerings and dedicated faculty members.

"Students confirm that 'the research and other academic opportunities... are very accessible to students who seek it out,'" the profile says. "This includes taking advantage of UH’s vast alumni network (more than 325,000 and counting), not to mention its location in the corporate center of Houston, where 'the opportunities that are provided are immense.'"

The 12 other public and private universities in Texas included in The Princeton Review's 2027 guide are:

The University of Texas at Austin
Southwestern University, Georgetown
Baylor University, Waco
Texas A&M University - College Station
Trinity University, San Antonio
