Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”

Pioneering Houston biotech startup expands to Brazil for next phase

On the Move

Houston biotech company Cemvita has expanded into Brazil. The company officially established a new subsidiary in the country under the same name.

According to an announcement made earlier this month, the expansion aims to capitalize on Brazil’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, which was enacted in 2024. The company said the expansion also aims to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals.

“For decades Brazil has pioneered the bioeconomy, and now the time has come to create the future of the circular bioeconomy,” Moji Karimi, CEO of Cemvita, said in a news release. “Our vision is to combine the innovation Cemvita is known for with Brazil’s expertise and resources to create an ecosystem where waste becomes opportunity and sustainability drives growth. By joining forces with Brazilian partners, Cemvita aims to build on Brazil’s storied history in the bioeconomy while laying the groundwork for a circular and sustainable future.”

The Fuel of the Future Law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

"This is all made possible by our innovative technology, which transforms carbon waste into value,” Marcio Da Silva, VP of Innovation, said in a news release. “Unlike traditional methods, it requires neither a large land footprint nor clean freshwater, ensuring minimal environmental impact. At the same time, it produces high-value green chemicals—such as sustainable oils and biofuels—without competing with the critical resources needed for food production."

In 2024, Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita quadrupled output at its Houston plant. The company had originally planned to reach this milestone in 2029.

Investor advocates now is the time to position Houston as a leading biomanufacturing hub

houston innovators podcast episode 178

Houston has all the ingredients to be a successful synthetic biology hub, says Veronica Wu. She believes so strongly in this that she relocated to Houston from Silicon Valley just over a year ago to start a venture capital firm dedicated to the field. Since then, she's doubled down on her passion for Houston leading in biotech — especially when it comes to one uniquely Houston opportunity: biomanufacturing.

While Houston's health care innovation scene is actively deploying synthetic biology applications, Wu points to Houston-based Solugen, a plant-based chemical producer, as an example of what Houston has to offer at-scale industrial biomanufacturing. Houston has the workforce and the physical space available for more of these types of biomanufacturing plants, which have a huge potential to move the needle on reducing carbon emissions.

"This is really fundamental technology that's going to change the paradigm and whole dialogue of how we are making a significant impact in reducing a carbon footprint and improving sustainability," says Wu, founder and managing partner of First Bight Ventures, on the Houston Innovators Podcast.

Several aspects — government funding, corporate interest, advances in technology — have converged to make it an ideal time for synthetic biology innovators and investors, Wu explains on the show, and she has an idea of what Houston needs to secure its spot as a leader in the space: The BioWell.

First introduced at a Houston Tech Rodeo event at the Texas Medical Center's Innovation Factory, The BioWell is a public-private partnership that aims to provide access to pilot and lab space, mentorship and programming, and more support that biomanufacturing innovators critically need.

"The way we envision The BioWell is it will provide a holistic, curated support for startups to be able to get across the Valley of Death," Wu says, explaining that startups transitioning from research and development into commercialization need extra support. The BioWell will provide that, as well as allow more engagement from corporations, investors, and other players.

Now that her plans for The BioWell have been announced, Wu is looking for those who want to be a part of it.

She shares more about her mission and what's next for First Bight Ventures on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Rice launches 'brain economy' initiative at World Economic Forum

brain health

Rice University has launched an initiative that will position “brain capital” as a key asset in the 21st century.

Rice rolled out the Global Brain Economy Initiative on Jan. 21 at the World Economic Forum in Davos, Switzerland.

“This initiative positions brain capital, or brain health and brain skills, at the forefront of global economic development, particularly in the age of artificial intelligence,” the university said in a news release.

The Rice-based initiative, whose partners are the University of Texas Medical Branch in Galveston and the Davos Alzheimer’s Collaborative, aligns with a recent World Economic Forum and McKinsey Health Institute report titled “The Human Advantage: Stronger Brains in the Age of AI,” co-authored by Rice researcher Harris Eyre. Eyre is leading the initiative.

“With an aging population and the rapid transformation of work and society driven by AI, the urgency has never been greater to focus on brain health and build adaptable human skills—both to support people and communities and to ensure long-term economic stability,” says Amy Dittmar, a Rice provost and executive vice president for academic affairs.

This initiative works closely with the recently launched Rice Brain Institute.

In its first year, the initiative will establish a global brain research agenda, piloting brain economy strategies in certain regions, and introducing a framework to guide financial backers and leaders. It will also advocate for public policies tied to the brain economy.

The report from the McKinsey Health Institute and World Economic Forum estimates that advancements in brain health could generate $6.2 trillion in economic gains by 2050.

“Stronger brains build stronger societies,” Eyre says. “When we invest in brain health and brain skills, we contribute to long-term growth, resilience, and shared prosperity.”

Rice Alliance and the Ion leader Brad Burke to retire this summer

lasting legacy

Brad Burke—a Rice University associate vice president who leads the Ion District’s Rice Alliance for Technology and Entrepreneurship and is a prominent figure in Houston’s startup community—is retiring this summer after a 25-year career at the university.

Burke will remain at the Rice Alliance as an adviser until his retirement on June 30.

“Brad’s impact on Rice extends far beyond any single program or initiative. He grew the Rice Alliance from a promising campus initiative into one of the most respected university-based entrepreneurship platforms,” Rice President Reginald DesRoches said in a news release.

During Burke’s tenure, the Rice Business School went from unranked in entrepreneurship to The Princeton Review’s No. 1 graduate entrepreneurship program for the past seven years and a top 20 entrepreneurship program in U.S. News & World Report’s rankings for the past 14 years.

“Brad didn’t just build programs — he built an ecosystem, a culture, and a reputation for Rice that now resonates around the world,” said Peter Rodriguez, dean of the business school. “Through his vision and steady leadership, Rice became a place where founders are taken seriously, ideas are rigorously supported, and entrepreneurship is embedded in the fabric of the university.”

One of Burke’s notable achievements at Rice is the creation of the Rice Business Plan Competition. During his tenure, the competition has grown from nine student teams competing for $10,000 into the world’s largest intercollegiate competition for student-led startups. Today, the annual competition welcomes 42 student-led startups that vie for more than $1 million in prizes.

Away from Rice, Burke has played a key role in cultivating entrepreneurship in the energy sector: He helped establish the Energy Tech Venture Forum along with Houston Energy and Climate Startup Week.

Furthermore, Burke co-founded the Texas University Network for Innovation and Entrepreneurship in 2008 to bolster the entrepreneurship programs at every university in Texas. In 2016, the Rice Alliance assumed leadership of the Global Consortium of Entrepreneurship Centers.

In 2023, Burke received the Trailblazer Award at the 2023 Houston Innovation Awards and was recognized by the Deshpande Foundation for his contributions to innovation and entrepreneurship in higher education.

“Working with an amazing team to build the entrepreneurial ecosystem at Rice, in Houston, and beyond has been the privilege of my career,” Burke said in the release. “It has been extremely gratifying to hear entrepreneurs say our efforts changed their lives, while bringing new innovations to market. The organization is well-positioned to help drive exponential growth across startups, investors, and the entrepreneurial ecosystem.”

Starting April 15, John “JR” Reale Jr. will serve as interim associate vice president at Rice and executive director of the Rice Alliance. He is managing director of the alliance and co-founder of Station Houston, beginning April 15. Reale is co-founder of the Station Houston startup hub and a startup investor and was also recently named director for startups and investor engagement for the Ion.

“The Rice Alliance has always been about helping founders gain advantages to realize their visions,” Reale said. “Under Brad’s leadership, the Rice Alliance has become a globally recognized platform that is grounded in trust and drives transformational founder outcomes. My commitment is to honor what Brad has built and led while continuing to serve our team and community, deepen relationships and deliver impact.”

Burke joined the Houston Innovators Podcast back in 2022. Listen to the full interview here.

Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

cancer research

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within.

Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum.

Gao and her team have developed Nano-273, a dual-function drug, packaged in an albumin-based particle, that boosts the immune system to help it better fight pancreatic and lung cancers. Gao’s lab recently received a $900,000 grant from the Cancer Prevention and Research Institute of Texas (CPRIT) to aid in fueling her research into the nanodrug.

“Nano-273 both activates STING and blocks PI3Kγ—a pathway that drives Breg expansion, while albumin nanoparticles help deliver the drug directly to immune cells, reducing unwanted side effects,” Gao said in a press release. “This approach reduces harmful Bregs while boosting immune cells that attack cancer, leading to stronger and more targeted anti-tumor responses.”

In studies using models of both pancreatic and lung cancers, Nano-273 has shown great promise with low toxicity. Its best results thus far have involved using the drug in combination with immunotherapy or chemotherapy.

With the CPRIT funds, Gao and her team will be able to charge closer to clinical use with a series of important steps. Those include continuing to test Nano-273 alongside other drugs, including immune checkpoint inhibitors. Safety studies will follow, but with future patients in mind, Gao will also work toward improving her drug’s production, making sure that it’s safe and high-quality every time, so that it is eventually ready for trials.

Gao added: “If successful, this project could lead to a new type of immunotherapy that offers lasting tumor control and improved survival for patients with pancreatic and lung cancers, two diseases that urgently need better treatments."
