T-cell immunotherapy is all the rage in the world of fighting cancer. A Houston company’s researchers have discovered a new subset of T cells that could be a game changer for patients.

CellChorus is a spinoff of Navin Varadarajan’s Single Cell Lab, part of the University of Houston’s Technology Bridge. The lab is the creator of TIMING, or Time-lapse Imaging Microscopy In Nanowell Grids. It’s a visual AI program that allows scientists to understand the functions of cells by evaluating cell activation, killing, and movement.

Last month, Nature Cancer published a paper co-authored by Varadarajan entitled, “Identification of a clinically efficacious CAR T cell subset in diffuse large B cell lymphoma by dynamic multidimensional single-cell profiling.”

“Our results showed that a subset of T cells, labeled as CD8-fit T cells, are capable of high motility and serial killing, found uniquely in patients with clinical response,” says first author and recent UH graduate Ali Rezvan in Nature Cancer.

Besides him and Varadarajan, contributors hail from Baylor College of Medicine/Texas Children’s Hospital, MD Anderson Cancer Center, Kite Pharma, and CellChorus itself.

The team identified the CD80-fit T cells using TIMING to examine interactions between T cells and tumor cells across thousands of individual cells. They were able to integrate the results using single-cell RNA sequencing data.

T-cell therapy activates a patient’s own immune system to fight cancer cells, but not every patient responds favorably to it. Identifying CD8-fit cells could be the key to manufacturing clinical response even in those for whom immunotherapy hasn’t been effective.

“This work illustrates the excellence of graduate students Ali Rezvan and Melisa Montalvo; and post-doctoral researchers Melisa Martinez-Paniagua and Irfan Bandey among others,” says Varadarajan in a statement.

Earlier last month, CellChorus recently received a $2.5 million SBIR grant. The money allows the company to share TIMING more widely, facilitating even more landmark discoveries like CD8-fit cells.

3 Houston cancer-focused research projects receive seed grants from new innovative initiative

funding the future

Three groundbreaking projects have just received seed grants from a new Houston-based source.

This spring, Rice University launched its Synthesis X Center with the goal of fostering the growth of cancer technologies and medications. Now, the SynthX, as it is known, and Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center have announced joint awards of grants to promising teams, all of which have principals at either Rice or Baylor.

The teams include:

  • A project from Drs. Pabel Miah of Baylor and Lei Li of Rice that involves the development and optimization of high-resolution imaging technology that’s intended for use in removing breast cancer from patients. The researchers combine ultrasound with photoacoustic technology to produce real-time imaging that allows surgeons to spot hard-to-locate tumors. This could reduce or eliminate tumor localization procedures which are invasive and costly.
  • A leukemia treatment profiting from molecular jackhammers, a type of molecule invented in the Rice University lab of Dr. James Tour. He’s joined in the project by Drs. Xin Li and Yongcheng Song, both of Baylor. Molecular jackhammers vibrate more than a trillion times per second when activated by a specific light frequency. Doing this can kill nearby cancer cells. The new treatment is intended to disrupt the activity of a transcription protein called ENL that helps fuel the growth of leukemia cells in several acute forms of the disease.
  • A project that could discover how to inspire cancer cells to kill themselves, using a cancer-associated enzyme called lysine demethylase 4A. Baylor’s Dr. Ruhee Dere and Rice’s Dr. Anna Karin-Gustavsson are studying the KDM4A with the process of apoptosis, or programmed cell death, in mind for the aberrant cells.

The seed grants are managed by Rice’s office for Educational and Research Initiatives for Collaborative Health (ENRICH). Each of the three grants is intended to last two years and includes funds of up to $80,000.

The goal is to allow research teams to collect preliminary data that can be used to apply for more substantial grants from bodies like the Cancer Prevention and Research Institute of Texas (CPRIT) or the National Institute of Health (NIH).

Three quarters of the funds will be provided in the first year. Teams that produce grant submissions with multiple principal investigators in that first year will be eligible to collect the additional quarter.

Houston organizations snag chunk of recently announced $49M cancer research grant funding

show me the money

Houston’s Baylor College of Medicine is beefing up its team of cancer researchers.

The college just received $6 million from the state agency Cancer Prevention and Research Institute of Texas (CPRIT) to recruit three cancer researchers: Graham Erwin, Michael Robertson and Dr. Varun Venkataramani. Each researcher is getting $2 million.

In addition, the University of Texas MD Anderson Cancer Center snagged a $2 million CPRIT grant to recruit Simon Eschweiler.

In all, CPRIT recently announced $49 million in cancer research and prevention grants, including nearly $24 million for recruitment of cancer researchers.

Here’s a rundown of the recruitment grants awarded in Houston:

  • Graham Erwin. Erwin is a postdoctoral fellow at Stanford University’s Stanford Cancer Institute. He’s a biologist who specializes in DNA sequencing related to the development of cancer therapeutics and diagnostics.
  • Michael Robertson. Robertson also is a postdoctoral fellow at Stanford. He focuses on molecular and cellular physiology at Stanford’s medical school.
  • Dr. Varun Venkataramani. Venkataramani, a neuroscientist, is a brain tumor researcher at University Hospital Heidelberg, one of the largest hospitals in Germany.
  • Simon Eschweiler. Eschweiler is a research assistant professor at Southern California’s La Jolla Institute for Immunology. He specializes in immunotherapy for cancer patients.

Aside from the recruitment grants, three institutions in the Houston area received nearly $6 million in funding for cancer treatment and prevention programs. Here’s an overview of those grants:

  • Almost $2.5 million for expansion of a program at the University of Texas Medical Branch at Galveston that supplies HPV vaccinations for new mothers.
  • Nearly $2.5 million for an MD Anderson program that promotes physical activity for cancer survivors.
  • Almost $500,000 for an MD Anderson program to increase treatment of tobacco users who are participating in opioid treatment programs.
  • Nearly $500,000 for a University of Houston program designed to help LGBTQ+ Texans lead tobacco-free lives.

“From new research programs, recruitment of preeminent scientists to Texas, pilot studies, new technology, and expanding the reach of successful cancer prevention programs, [the] grants highlight the effect CPRIT is having on not just cancer research and prevention efforts, but on life science infrastructure in Texas,” Wayne Roberts, the organization’s CEO, said in a news release.

UH team lands $4.7M grant for discovery linking origins of two aggressive cancers

funds granted

Frank McKeon, professor of biology and biochemistry and director of the Somatic Stem Cell Center at the University of Houston, will lead a new five-year $4.7 million grant from the National Cancer Institute to advance important findings about aggressive stomach and esophageal cancers.

McKeon and a team of researchers have already uncovered a surprising finding about two types of cancers: stomach and esophagus esophageal adenocarcinoma (EAC) and intestinal gastric cancer (iGC). According to their research, the two cancers have identical precursor stem cells or "cells of origin."

The cells are highly susceptible to mutations, which can cause them to develop into cancerous lesions.

Currently, patients who present these types of lesions struggle with an advanced disease with a low survival rate, according to a statement from UH.

"We anticipate that the identification of these cells will enable drug discovery to pre-empt these cancers at their site of origin,” McKeon said in a statement.

Uncovering this information about the cancers' cells of origin also helps researchers group EAC and iGC as a cluster distinct from other gastric and esophageal cancers.

McKeon will be joined on the project by Wa Xian, research associate professor of biology and biochemistry at UH, and Dr. Jaffer Ajani of MD Anderson Cancer Center.

Xian is an expert in stem cell cloning. The team aims to clone the EAC and iGC precursor legions to better understand the evolution of the cancers as part of their research.

"We anticipate that our studies will provide new insights into the biology and origin of these remarkably similar and widespread cancers, provide datasets essential for prospective early detection screens and yield highly selective therapeutics that eliminate the nascent lesions essential for the evolution of these cancers,” McKeon added in the statement.

Other UH researchers have received major grants for cancer-fighting innovations in recent months. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston and a M.D. Anderson professor in the Department of Biology & Biochemistry, received a $1.8 million grant from the National Institutes of Health to develop a cancer-fighting virus in July.

The nonprofit Cancer Prevention & Research Institute of Texas (CPRIT) also shelled out nearly $22 million in grants to successfully lure nine high-profile cancer researchers to Houston late last year.

University of Houston researchers snag $1.8M to develop cancer-fighting virus

immunotherapy innovation

Viruses attack human cells, and that's usually a bad thing — some Houston researchers have received fresh funding to develop and use the evil powers of viruses for good.

The developing cancer treatment is called oncolytic virotherapy and has risen in popularity among immunotherapy research. The viruses can kill cancer cells while being ineffective to surrounding cells and tissue. Basically, the virus targets the bad guys by "activating an antitumor immune response made of immune cells such as natural killer (NK) cells," according to a news release from the University of Houston.

However exciting this rising OV treatment seems, the early stage development is far from perfect. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston, is hoping his work will help improve OV treatment and make it more effective.

“We have developed a novel strategy that not only can prevent NK cells from clearing the administered oncolytic virus, but also goes one step further by guiding them to attack tumor cells. We took an entirely different approach to create this oncolytic virotherapy by deleting a region of the gene which has been shown to activate the signaling pathway that enables the virus to replicate in normal cells,” Zhang says in the release.

Zhang, who is also a M.D. Anderson professor in the Department of Biology & Biochemistry, has received a $1.8 million grant from the National Institutes of Health to continue his work.

Zhang and his team are specifically creating a new OV — called FusOn-H2 and based on the Herpes simplex 2 virus.

“Our recent studies showed that arming FusOn-H2 with a chimeric NK engager (C-NK-E) that can engage the infiltrated natural killer cells with tumor cells could significantly enhance the effectiveness of this virotherapy,” he says. “Most importantly, we observed that tumor destruction by the joint effect of the direct oncolysis and the engaged NK cells led to a measurable elicitation of neoantigen-specific antitumor immunity.”

Houston engineers develop breakthrough device to advance spinal cord treatment

future of health

A team of Rice University engineers has developed an implantable probe over a hundred times smaller than the width of a hair that aims to help develop better treatments for spinal cord disease and injury.

Detailed in a recent study published in Cell Reports, the probe or sensor, known as spinalNET, is used to explore how neurons in the spinal cord process sensation and control movement, according to a statement from Rice. The research was supported by the National Institutes of Health, Rice, the California-based Salk Institute for Biological Studies, and the philanthropic Mary K. Chapman Foundation based in Oklahoma.

The soft and flexible sensor was used to record neuronal activity in freely moving mice with high resolution for multiple days. Historically, tracking this level of activity has been difficult for researchers because the spinal cord and its neurons move so much during normal activity, according to the team.

“We developed a tiny sensor, spinalNET, that records the electrical activity of spinal neurons as the subject performs normal activity without any restraint,” Yu Wu, a research scientist at Rice and lead author of the study said in a statement. “Being able to extract such knowledge is a first but important step to develop cures for millions of people suffering from spinal cord diseases.”

The team says that before now the spinal cord has been considered a "black box." But the device has already helped the team uncover new findings about the body's rhythmic motor patterns, which drive walking, breathing and chewing.

"Some (spinal neurons) are strongly correlated with leg movement, but surprisingly, a lot of neurons have no obvious correlation with movement,” Wu said in the statement. “This indicates that the spinal circuit controlling rhythmic movement is more complicated than we thought.”

The team said they hope to explore these findings further and aim to use the technology for additional medical purposes.

“In addition to scientific insight, we believe that as the technology evolves, it has great potential as a medical device for people with spinal cord neurological disorders and injury,” Lan Luan, an associate professor of electrical and computer engineering at Rice and a corresponding author on the study, added in the statement.

Rice researchers have developed several implantable, minimally invasive devices to address health and mental health issues.

In the spring, the university announced that the United States Department of Defense had awarded a four-year, $7.8 million grant to the Texas Heart Institute and a Rice team led by co-investigator Yaxin Wang to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation.

That same month, the university shared news that Professor Jacob Robinson had published findings on minimally invasive bioelectronics for treating psychiatric conditions. The 9-millimeter device can deliver precise and programmable stimulation to the brain to help treat depression, obsessive-compulsive disorder and post-traumatic stress disorder.

Houston clean hydrogen startup to pilot tech with O&G co.

stay gold

Gold H2, a Houston-based producer of clean hydrogen, is teaming up with a major U.S.-based oil and gas company as the first step in launching a 12-month series of pilot projects.

The tentative agreement with the unnamed oil and gas company kicks off the availability of the startup’s Black 2 Gold microbial technology. The technology underpins the startup’s biotech process for converting crude oil into proprietary Gold Hydrogen.

The cleantech startup plans to sign up several oil and gas companies for the pilot program. Gold H2 says it’s been in discussions with companies in North America, Latin America, India, Eastern Europe and the Middle East.

The pilot program is aimed at demonstrating how Gold H2’s technology can transform old oil wells into hydrogen-generating assets. Gold H2, a spinout of Houston-based biotech company Cemvita, says the technology is capable of producing hydrogen that’s cheaper and cleaner than ever before.

“This business model will reshape the traditional oil and gas industry landscape by further accelerating the clean energy transition and creating new economic opportunities in areas that were previously dismissed as unviable,” Gold H2 says in a news release.

The start of the Black 2 Gold demonstrations follows the recent hiring of oil and gas industry veteran Prabhdeep Singh Sekhon as CEO.

“With the proliferation of AI, growth of data centers, and a national boom in industrial manufacturing underway, affordable … carbon-free energy is more paramount than ever,” says Rayyan Islam, co-founder and general partner at venture capital firm 8090 Industries, an investor in Gold H2. “We’re investing in Gold H2, as we know they’ll play a pivotal role in unleashing a new dawn for energy abundance in partnership with the oil industry.”
