IIT Madras Researchers Engineer Plant Cells To Produce Drug For Cancer

Researchers from the prestigious Indian Institutes of Technology (IIT) Madras and Mandi have achieved a significant milestone in the field of biotechnology. They have successfully metabolically engineered plant cells to boost the production of the anti-cancer drug camptothecin (CPT).

Addressing the Challenge of Endangered Plant Conservation

CPT, traditionally extracted from the endangered plant Nathapodytes nimmoniana, has been a source of concern due to the plant’s declining population. The International Union for Conservation of Nature has red-listed this species, noting a 20% decrease in its population in the past decade. This development by IIT researchers comes as a critical solution to both medicinal production and plant conservation.

Innovative Research for Sustainable Production

In a groundbreaking research paper published in 2021, IIT Madras researchers identified a sustainable and high-yielding microbe alternative for CPT production. The Plant Cell Technology Lab at IIT Madras, using computational tools, developed a genome-scale metabolic model for N. nimmoniana plant cells.

The Team Behind the Innovation

This notable achievement was the result of collaborative efforts by a team of experts. Professors Karthik Raman and Smita Srivastava of the Biotechnology department at IIT Madras, along with Sarayu Murali and Maziya Ibrahim of the Computational Systems Biology Lab, and Shyam K. Masakapalli and Shagun Saini from the Metabolic Systems Biology Lab at IIT Mandi, spearheaded this research.

Funding and Recognition

The Science and Engineering Board (SERB) and the Department of Science and Technology provided essential funding for this research, which was published in the esteemed peer-reviewed journal, Frontiers of Plant Science.

Enhanced and Sustainable Drug Production

Principal investigator Smita Srivastava emphasized the integration of metabolic and bioprocess engineering principles as key to ensuring an enhanced and sustainable drug production. This approach is not just innovative but also addresses the growing market demand efficiently.

The Future of Commercial Viability

The research focuses on overexpressing certain genes in the plant to increase CPT production, analogous to widening roads to allow more traffic flow. The goal is to make this process commercially feasible within three to five years, thereby revolutionizing the way this vital cancer drug is manufactured.
