Rice University chemist Han Xiao, who also serves as director of the university’s Synthesis X Center, and cancer biologist Dihua Yu of The University of Texas MD Anderson Cancer Center have received a three-year, $1.5 million grant from the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation.

The funding will allow them to continue their research on treating brain metastasis by overcoming the blood-brain barrier, or the BBB, according to a news release.

Brain metastasis is the leading form of brain cancer, with survival rates below 20 percent within a year of diagnosis, according to the National Library of Medicine. It commonly originates from breast, lung and melanoma cancers.

The BBB typically acts as a protective barrier for the brain. However, it prevents most drugs from being able to directly reach the brain. According to Rice, only 2 percent of FDA-approved small molecule drugs can penetrate the BBB, limiting treatment options.

Xiao and Yu’s approach to dealing with the BBB includes a light-induced brain delivery (LIBD) platform. The advanced system employs nanoparticles that are embedded with a near-infrared dye for the transport of therapeutic agents across the BBB. The research will evaluate the LIBD’s ability to improve the delivery of small-molecule drugs and biological therapies. Some therapies have shown potential for reducing cancer growth in laboratory studies, but they have struggled due to limited BBB penetration in animal models.

“Our LIBD platform represents a novel strategy for delivering drugs to the brain with precision and efficiency,” Xiao said in a news release. “This technology could not only improve outcomes for brain metastasis patients but also pave the way for treating other neurological diseases.”

The Kleberg Foundation looks for groundbreaking medical research proposals from leading institutions that focus on “innovative basic and applied biological research that advances scientific knowledge and human health” according to the foundation.

“This research is a testament to the power of collaboration and innovation,” Xiao said in a news release. “Together, we’re pushing the boundaries of what’s possible in treating brain metastasis and beyond.”

Rice launched the Synthesis X Center, or Synth X, last spring. It was born out of what started about eight years ago as informal meetings between Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center. It aims to turn fundamental research into clinical applications through collaboration.

“This collaboration builds on the strengths of both research teams,” Xiao said in the release. “By combining SynthX Center's expertise in chemistry with Dr. Yu's expertise in cancer biology and brain metastases, we aim to create a transformative solution.”

The funds were awarded to Han Xiao, a scientist at Rice University.

Houston chemist lands $2M NIH grant for cancer treatment research

future of cellular health

A Rice University chemist has landed a $2 million grant from the National Institute of Health for his work that aims to reprogram the genetic code and explore the role certain cells play in causing diseases like cancer and neurological disorders.

The funds were awarded to Han Xiao, the Norman Hackerman-Welch Young Investigator, associate professor of chemistry, from the NIH's Maximizing Investigators’ Research Award (MIRA) program, which supports medically focused laboratories.

Xiao will use the five-year grant to develop noncanonical amino acids (ncAAs) with diverse properties to help build proteins, according to a statement from Rice. He and his team will then use the ncAAs to explore the vivo sensors for enzymes involved in posttranslational modifications (PTMs), which play a role in the development of cancers and neurological disorders. Additionally, the team will look to develop a way to detect these enzymes in living organisms in real-time rather than in a lab.

“This innovative approach could revolutionize how we understand and control cellular functions,” Xiao said in the statement.

According to Rice, these developments could have major implications for the way diseases are treated, specifically for epigenetic inhibitors that are used to treat cancer.

Xiao helped lead the charge to launch Rice's new Synthesis X Center this spring. The center, which was born out of informal meetings between Xio's lab and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center at the Baylor College of Medicine, aims to improve cancer outcomes by turning fundamental research into clinical applications.

They will build upon annual retreats, in which investigators can share unpublished findings, and also plan to host a national conference, the first slated for this fall titled "Synthetic Innovations Towards a Cure for Cancer.”

Houston organizations launch collaborative center to boost cancer outcomes

new to HOU

Rice University's new Synthesis X Center officially launched last month to bring together experts in cancer care and chemistry.

The center was born out of what started about seven years ago as informal meetings between Rice chemist Han Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center at the Baylor College of Medicine. The level of collaboration between the two teams has grown significantly over the years, and monthly meetings now draw about 100 participants from across disciplines, fields and Houston-based organizations, according to a statement from Rice.

Researchers at the new SynthX Center will aim to turn fundamental research into clinical applications and make precision adjustments to drug properties and molecules. It will focus on improving cancer outcomes by looking at an array of factors, including prevention and detection, immunotherapies, the use of artificial intelligence to speed drug discovery and development, and several other topics.

"At Rice, we are strong on the fundamental side of research in organic chemistry, chemical biology, bioengineering and nanomaterials,” Xiao says in the statement. “Starting at the laboratory bench, we can synthesize therapeutic molecules and proteins with atom-level precision, offering immense potential for real-world applications at the bedside ... But the clinicians and fundamental researchers don’t have a lot of time to talk and to exchange ideas, so SynthX wants to serve as the bridge and help make these connections.”

SynthX plans to issue its first merit-based seed grants to teams with representatives from Baylor and Rice this month.

With this recognition from Rice, the teams from Xiao's lab and the TMC will also be able to expand and formalize their programs. They will build upon annual retreats, in which investigators can share unpublished findings, and also plan to host a national conference, the first slated for this fall titled "Synthetic Innovations Towards a Cure for Cancer.”

“I am confident that the SynthX Center will be a great resource for both students and faculty who seek to translate discoveries from fundamental chemical research into medical applications that improve people’s lives,” Thomas Killian, dean of the Wiess School of Natural Sciences, says in the release.

Rice announced that it had invested in four other research centers along with SynthX last month. The other centers include the Center for Coastal Futures and Adaptive Resilience, the Center for Environmental Studies, the Center for Latin American and Latinx Studies and the Rice Center for Nanoscale Imaging Sciences.

Earlier this year, Rice also announced its first-ever recipients of its One Small Step Grant program, funded by its Office of Innovation. The program will provide funding to faculty working on "promising projects with commercial potential," according to the website.

Axiom Space-tested cancer drug advances to clinical trials

mission critical

A cancer-fighting drug tested aboard several Axiom Space missions is moving forward to clinical trials.

Rebecsinib, which targets a cancer cloning and immune evasion gene, ADAR1, has received FDA approval to enter clinical trials under active Investigational New Drug (IND) status, according to a news release. The drug was tested aboard Axiom Mission 2 (Ax-2) and Axiom Mission 3 (Ax-3). It was developed by Aspera Biomedicine, led by Dr. Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute (SSCI).

The San Diego-based Aspera team and Houston-based Axiom partnered to allow Rebecsinib to be tested in microgravity. Tumors have been shown to grow more rapidly in microgravity and even mimic how aggressive cancers can develop in patients.

“In terms of tumor growth, we see a doubling in growth of these little mini-tumors in just 10 days,” Jamieson explained in the release.

Rebecsinib took part in the patient-derived tumor organoid testing aboard the International Space Station. Similar testing is planned to continue on Axiom Station, the company's commercial space station that's currently under development.

Additionally, the drug will be tested aboard Ax-4 under its active IND status, which was targeted to launch June 25.

“We anticipate that this monumental mission will inform the expanded development of the first ADAR1 inhibitory cancer stem cell targeting drug for a broad array of cancers," Jamieson added.

According to Axiom, the milestone represents the potential for commercial space collaborations.

“We’re proud to work with Aspera Biomedicines and the UC San Diego Sanford Stem Cell Institute, as together we have achieved a historic milestone, and we’re even more excited for what’s to come,” Tejpaul Bhatia, the new CEO of Axiom Space, said in the release. “This is how we crack the code of the space economy – uniting public and private partners to turn microgravity into a launchpad for breakthroughs.”
