Not all heroes wear capes. Some wear lab coats. Almost daily, it seems there's a new breakthrough or discovery for life-saving innovations.

These three cancer-related innovations are coming out of Houston, and they are ones to watch.

Researchers from the University of Houston have teamed up with their colleagues at the University of Pennsylvania to try to get a biosensor that can detect the recurrence of prostate cancer into the doctor's office.

The research is funded by a $399,988 grant from the National Science Foundation and led by Dmitri Litvinov, principal investigator and professor of electrical and computer engineering at UH.

"Such tests exist in clinical laboratories, but there remains a critical need for inexpensive, versatile and high-sensitivity diagnostic platforms which can bring the performance to the point of care or doctor's office," says Litvinov in a release.

The biosensor platform would be less than $3 per test — an alluring fact for patients and health care providers — and would function more or less like a pregnancy test, but without a simple positive or negative response. Rather, the test can assess how much prostate-specific antigen is in a patient's blood

"Our technology has potential to help improve survival rates with more accessible, affordable and easier testing," Litvinov says.

A recent study in the Proceedings of the National Academy of Sciences revealed that a cancer-linked version of the protein mitoNEET can shut the gateways of mitochondria cells that supply chemical energy.

José Onuchic, a physicist and co-director of Rice University's Center for Theoretical Biological Physics, co-authored the paper and noted that the gateways, called voltage-dependent anion channels, or VDACs, typically open and shut to allow the passage of metabolites and other small molecules between mitochondria and the rest of the cell.

"The VDAC channel transports all types of metabolites between the cytosol and the mitochondria," says Onuchic in a release. "Dysfunction of this channel is involved in many diseases including cancer and fatty liver disease."

Co-author Patricia Jennings, a structural biologist at UCSD, explains in the news release.

"The discovery that mitoNEET directly gates VDAC, the major porin of mitochondria, as well as the accompanying structural analysis and predictions for this interaction, affords a new platform for investigations of methods to induce cancer cells to commit cell suicide, or apoptosis/ferroptosis, in a cancer-specific, regulated process," she writes.

The study opens doors for a new approach to cancer-treating drugs.

"Fine-tuning a drug that specifically alters the redox-state of interaction between VDAC and mitoNEET would allow the development of new weapons to battle multiple cancers," Onuchic says.

Baylor College of Medicine's digital tool for childhood cancer survivors

Childhood cancer survivors face a lifetime of obstacles to overcome, and Baylor College of Medicine and Texas Children's Cancer Center have developed a resource to help these patients have the best quality of life in remission.

Passport for Care, a free online resource, features a "survivorship care plan" for the patient, his or her doctor, and family members. The program's new Screenings Recommendations Generator tool can provide a childhood cancer survivor with potential late effects and how to manage their care.

"This tool is especially helpful for patients who have moved on to other doctors who they did not see as a child and who might not be familiar with their particular treatment and the subsequent health risks," says Dr. David Poplack, founder of the Passport for Care and associate director of the Texas Children's Cancer and Hematology Centers, in a news release. "It helps physicians understand their patient's history and know how to address future health problems."

Over 37,000 cancer survivors are using Passport for Care at 138 clinics around the world. Additionally, patients can also register through the Screenings Recommendations Generator.

Passport for Care is funded by the Cancer Prevention & Research Institute of Texas, as well as through a grant from Hyundai Hope on Wheels.

"We created Passport for Care with the goal of empowering survivors in their healthcare decisions," Poplack says. "Their care doesn't end when cancer treatment is over. Survivorship care is a lifelong journey."

Houston doctor wins NIH grant to test virtual reality for ICU delirium

Virtual healing

Think of it like a reverse version of The Matrix. A person wakes up in a hospital bed and gets plugged into a virtual reality game world in order to heal.

While it may sound far-fetched, Dr. Hina Faisal, a Houston Methodist critical care specialist in the Department of Surgery, was recently awarded a $242,000 grant from the National Institute of Health to test the effects of VR games on patients coming out of major surgery in the intensive care unit (ICU).

The five-year study will focus on older patients using mental stimulation techniques to reduce incidences of delirium. The award comes courtesy of the National Institute on Aging K76 Paul B. Beeson Emerging Leaders Career Development Award in Aging.

“As the population of older adults continues to grow, the need for effective, scalable interventions to prevent postoperative complications like delirium is more important than ever,” Faisal said in a news release.

ICU delirium is a serious condition that can lead to major complications and even death. Roughly 87 percent of patients who undergo major surgery involving intubation will experience some form of delirium coming out of anesthesia. Causes can range from infection to drug reactions. While many cases are mild, prolonged ICU delirium may prevent a patient from following medical advice or even cause them to hurt themselves.

Using VR games to treat delirium is a rapidly emerging and exciting branch of medicine. Studies show that VR games can help promote mental activity, memory and cognitive function. However, the full benefits are currently unknown as studies have been hampered by small patient populations.

Faisal believes that half of all ICU delirium cases are preventable through VR treatment. Currently, a general lack of knowledge and resources has been holding back the advancement of the treatment.

Hopefully, the work of Faisal in one of the busiest medical cities in the world can alleviate that problem as she spends the next half-decade plugging patients into games to aid in their healing.

Houston scientists develop breakthrough AI-driven process to design, decode genetic circuits

biotech breakthrough

Researchers at Rice University have developed an innovative process that uses artificial intelligence to better understand complex genetic circuits.

A study, published in the journal Nature, shows how the new technique, known as “Combining Long- and Short-range Sequencing to Investigate Genetic Complexity,” or CLASSIC, can generate and test millions of DNA designs at the same time, which, according to Rice.

The work was led by Rice’s Caleb Bashor, deputy director for the Rice Synthetic Biology Institute and member of the Ken Kennedy Institute. Bashor has been working with Kshitij Rai and Ronan O’Connell, co-first authors on the study, on the CLASSIC for over four years, according to a news release.

“Our work is the first demonstration that you can use AI for designing these circuits,” Bashor said in the release.

Genetic circuits program cells to perform specific functions. Finding the circuit that matches a desired function or performance "can be like looking for a needle in a haystack," Bashor explained. This work looked to find a solution to this long-standing challenge in synthetic biology.

First, the team developed a library of proof-of-concept genetic circuits. It then pooled the circuits and inserted them into human cells. Next, they used long-read and short-read DNA sequencing to create "a master map" that linked each circuit to how it performed.

The data was then used to train AI and machine learning models to analyze circuits and make accurate predictions for how untested circuits might perform.

“We end up with measurements for a lot of the possible designs but not all of them, and that is where building the (machine learning) model comes in,” O’Connell explained in the release. “We use the data to train a model that can understand this landscape and predict things we were not able to generate data on.”

Ultimately, the researchers believe the circuit characterization and AI-driven understanding can speed up synthetic biology, lead to faster development of biotechnology and potentially support more cell-based therapy breakthroughs by shedding new light on how gene circuits behave, according to Rice.

“We think AI/ML-driven design is the future of synthetic biology,” Bashor added in the release. “As we collect more data using CLASSIC, we can train more complex models to make predictions for how to design even more sophisticated and useful cellular biotechnology.”

The team at Rice also worked with Pankaj Mehta’s group in the department of physics at Boston University and Todd Treangen’s group in Rice’s computer science department. Research was supported by the National Institutes of Health, Office of Naval Research, the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation, the American Heart Association, National Library of Medicine, the National Science Foundation, Rice’s Ken Kennedy Institute and the Rice Institute of Synthetic Biology.

James Collins, a biomedical engineer at MIT who helped establish synthetic biology as a field, added that CLASSIC is a new, defining milestone.

“Twenty-five years ago, those early circuits showed that we could program living cells, but they were built one at a time, each requiring months of tuning,” said Collins, who was one of the inventors of the toggle switch. “Bashor and colleagues have now delivered a transformative leap: CLASSIC brings high-throughput engineering to gene circuit design, allowing exploration of combinatorial spaces that were previously out of reach. Their platform doesn’t just accelerate the design-build-test-learn cycle; it redefines its scale, marking a new era of data-driven synthetic biology.”
