RIO GRANDE VALLEY, TEXAS – JUNE 3, 2025 – In labs at the UTRGV School of Medicine, researchers like Dr. Diane Nguyen, Dr. Sheema Khan and Dr. Murali Yallapu working to change how cancer is understood and treated, both in the Rio Grande Valley and beyond.

Khan and Yallapu are part of the South Texas Center of Excellence in Cancer Research, where they are developing next-generation diagnostics and therapies for some of the area’s most aggressive and deadly cancers, including breast, cervical, liver, pancreatic, colorectal, and gastrointestinal cancers.

Their shared goal is to bring the latest in medicine to a region historically underserved in cancer care.

“My focus on medicine and cancer research has been shaped by a strong sense of social responsibility and service,” said Khan, assistant professor in the Division of Immunology and Microbiology at the UTRGV School of Medicine and a member of the South Texas Center for Excellence in Cancer Research. “I’ve seen the toll it can take physically, emotionally and socially. Every discovery we make in the lab has the potential to save lives.”

RGV RESEARCH, RGV IMPACT

Khan’s work focuses on the tumor microenvironment, the immune cells, blood vessels, structural tissue, and microorganisms that surround a tumor and can influence its growth.

“In gastrointestinal cancers, this microenvironment can block effective drug delivery and help cancer cells grow uncontrollably,” she said. “By understanding these interactions, we can design more targeted treatments tailored to the biology of each tumor and patient.” 

Colleague Yallapu shares that commitment to precision medicine: His lab is pioneering smart nanoparticle systems to deliver cancer drugs more efficiently and with fewer side effects.

“We’re developing nanoparticles that can seek out tumor cells and release drugs directly into them,” said Yallapu, associate professor in the Division of Immunology and Microbiology at the UTRGV School of Medicine at the UTRGV School of Medicine. “It’s a way to improve treatment success while reducing the toxicity that comes with traditional chemotherapy.”

The researchers emphasize the shift from a one-size-fits-all approach to one that’s more personalized.

“Traditional chemotherapy is like a sledgehammer,” Khan said. “But therapies like antibody-drug conjugates and nano-immunotherapies act more like guided missiles. They go directly to the tumor and spare healthy tissue.”

Their work already is having a great impact. The team recently discovered distinct gut microbiome patterns in Valley patients with liver cancer and non-alcoholic fatty liver disease (NAFLD), a condition common in South Texas.

Some bacterial strains found in tumors may serve as early biomarkers for cancer risk, while others may offer protection. These findings could help pave the way for earlier detection and new prevention strategies.

CARE AT HOME

Cancer patients in the Valley soon will have access to a centralized facility offering comprehensive cancer treatment, diagnostics and research – all in one place. 

Slated to open in 2025, the new UT Health RGV Cancer and Surgery Center will serve as more than a treatment facility. It also will be a center for cancer research where scientists and clinicians can collaborate to improve the options and possibilities for Valley patients.

Dr. Diane Nguyen, Kleberg Foundation Endowed Chair and chief of the Division of Medical Oncology at UT Health RGV, said the cancer center will expand opportunities for clinical research and trials at the UTRGV School of Medicine.

A member of the American Association for Cancer Research (AACR), the American Society of Clinical Oncology (ASCO), and the American Society of Hematology (ASH), Nguyen emphasized that groundbreaking cancer research is already happening in the Valley. 

“People often think major advances only happen in big cities,” she said. “But importantly, innovative research is happening right here at home and it’s improving outcomes for our local patients.” 

She said cancer research is a field in which scientific discovery can translate directly into saving lives.

“It’s a team effort. Everyone works together, the scientists in the lab and the clinicians caring for patients,” she said. “Here in South Texas, we have an opportunity to build a model for cancer research that addresses health disparities head-on.”

Dr. Everardo Cobos, interim dean of the UTRGV School of Medicine and chair of the Department of Medicine and Oncology, agrees that the UT Health RGV Cancer and Surgery Center represents a turning point for cancer research in the Valley.

“It’s about giving our patients access to the best care and the latest treatments without leaving their community,” he said. “We’re building something lasting, something that will benefit the Rio Grande Valley for years to come.”

ABOUT UTRGV

The University of Texas Rio Grande Valley (UTRGV) was created by the Texas Legislature in 2013 as the first major public university of the 21st century in Texas. This transformative initiative provided the opportunity to expand educational opportunities in the Rio Grande Valley, including a new School of Medicine and a School of Podiatry, and made it possible for residents of the region to benefit from the Permanent University Fund – a public endowment contributing support to the University of Texas System and other institutions.

UTRGV has campuses and off-campus research and teaching sites throughout the Rio Grande Valley including Brownsville (formerly The University of Texas at Brownsville campus), Edinburg (formerly The University of Texas-Pan American campus), Harlingen, Weslaco, McAllen, Port Isabel, Rio Grande City and South Padre Island. UTRGV, a comprehensive academic institution, enrolled its first class in the fall of 2015; the School of Medicine welcomed its first class in the summer of 2016, and the School of Podiatric Medicine in the fall of 2022.
