University of Hyderabad in the quest of climate-proof super grains
From tilling the soil to harvesting by hand, every step is carried out with care. Here, fieldwork meets genomics, where the sweat of the brow is matched by scientific precision, all in pursuit of developing climate-resilient, nutrient-rich grains.
Leading this effort is Dr Mehanathan Muthamilarasan, who launched The Millet Lab in 2020 with a clear mission: to decode the genetic makeup of millets and enhance their natural resilience through cutting-edge gene editing. In India, the world's largest millet producer, this research couldn't be more timely. With droughts, soil degradation and salinity threatening food systems, millets may hold the key to ensuring nutritional security in the years to come.
Dr Muthamilarasan notes a sharp contrast within the grass family: rice, wheat and millets may be botanical cousins, but when it comes to climate resilience, millets stand apart. Producing 1 kg of rice takes around 2,500 litres of water, compared to just 250 litres for the same amount of millets.
Rather than pushing for a sudden shift away from rice, his team is working on a visionary solution: identifying climate-resilient genes in foxtail millet (korralu in Telugu) and transferring them into rice through genetic engineering. So far, they've mapped over 500 key genes that could help staple crops survive extreme environmental stress.
Backed by the Department of Biotechnology (DBT) and the Anusandhan National Research Foundation (ANRF), the team recently identified a stress-associated protein gene in millets that enables the plant to endure extreme heat. This breakthrough could be pivotal in developing heat-tolerant crops, critical in an era of rising temperatures.
Researcher Pooja Shukla, who works closely on the project, tells TNIE, 'We cultivate and study foxtail and kodo millets at our university farm.'

Hyderabad: City startup achieves global first in regenerative medicine for liver failure
Hyderabad: In a significant achievement for India's biotechnology sector, Tulsi Therapeutics, a startup incubated at ASPIRE-BioNEST at the University of Hyderabad, has announced the world's first successful animal trial of a novel stem cell-exosome combination therapy for chronic liver failure. The investigational product, Tulsi-28X, is a groundbreaking regenerative therapy derived from Wharton's Jelly mesenchymal stem cells and their native exosomes. It's a combination that has never been tested in any animal model worldwide. Although conceptualised in the United States, the platform was developed in India through three years of intensive research at ASPIRE-BioNEST. The preclinical trial, conducted in collaboration with global experts including Dr. Naga Chalasani (Indiana University, USA) and Dr. Ajay Duseja (PGIMER, Chandigarh), demonstrated 100% of the animals treated with Tulsi-28x showed reversal of liver fibrosis (indicating liver regeneration) resulting in zero deaths, compared to only 14% reversal (p<0.001) and 43% deaths (p<0.0066) in the untreated control group. 'This is a significant milestone for India's biotech industry,' said Dr. Sairam Atluri, Founder & CEO of Tulsi Therapeutics. 'ASPIRE-BioNEST provided a world-class platform that helped us translate our vision into scientific reality. While human trials are the next challenge, this study opens doors to a new class of biologics in liver disease.' Key results were presented at the prestigious AASLD 2024 Liver Conference in San Diego and accepted for publication in the Journal of Regenerative Medicine. Tulsi Therapeutics is recognised as the world's first biotech company developing a dual stem cell–exosome biologic. Tulsi-28X works by secreting regenerative proteins and growth factors, stimulating the repair of diseased liver tissue. 'We are committed to developing world-class yet affordable regenerative solutions,' said Dr. Ravi Bonthala, Chief Scientific Officer, Tulsi Therapeutics. 'Our next step is to take Tulsi-28X into human clinical trials in collaboration with Nizam's Institute of Medical Sciences (NIMS).' Chronic liver failure remains a serious public health concern in India, contributing to nearly 20% of global liver-related deaths. With transplantation being the only current treatment, Tulsi-28X represents a potential paradigm shift. 'This milestone highlights how India's innovation ecosystem—anchored by institutions like the University of Hyderabad and enabled by BIRAC and incubators like ASPIRE-BioNEST—is capable of delivering breakthrough global biotech products,' said Prof. B.J. Rao, Vice Chancellor, University of Hyderabad. 'It reflects the power of science, policy, and startup synergy.' 'Tulsi Therapeutics' achievement is a proud moment for all of us at ASPIRE-BioNEST,' said Dr. Anil Kondreddy, CEO, ASPIRE-BioNEST. 'It reflects our mission to nurture science-led innovation with real-world impact. Being rooted in the University of Hyderabad gives us the strength of academic excellence, and it's incredibly fulfilling to see this ecosystem support a global-first breakthrough in regenerative medicine. This is precisely the kind of outcome we work to enable.'

City startup incubated at UoH develops stem cell treatment for chronic liver failure
Hyderabad: A startup incubated at the University of Hyderabad (UoH) successfully tested a new treatment for chronic liver failure using stem cells. Called Tulsi-28X, the treatment is touted to be the first in the world by the firm to use a special combination of stem cells and natural healing particles called exosomes. These are taken from a part of the umbilical cord known as Wharton's Jelly. Although the concept was born in the US, the entire platform was developed in India by Tulsi Therapeutics after three years of rigorous research at ASPIRE-BioNEST, UoH's biotech incubator. "We have done trials on rats. All animals treated with Tulsi-28X showed reversal of liver fibrosis, indicating liver regeneration, resulting in zero deaths, compared to only 14% reversal and 43% deaths in the untreated control group," Dr Sairam Atluri, founder & CEO of Tulsi Therapeutics, told TOI. The preclinical trial was conducted in collaboration with Indiana University, US, and PGIMER, Chandigarh. He said that this treatment method can be a game-changer as it would give a new lease of life to those with liver failure and waiting for transplantation. "Right now, the only treatment for liver failure is transplant. However, there are not enough donors, the treatment is very expensive, and it comes with various complications. The medicine that we developed can be administered intravenously," added Atluri, and said he moved from the US to India to work on this idea and bring it to life.

"Our next step is to take Tulsi-28X into human clinical trials in collaboration with Nizam's Institute of Medical Sciences."
