Researchers Discover Mechanism Linked to Cellular Respiration

In a study published in the December issue of Cell Metabolism, Miller School scientists have uncovered a system that regulates the formation of the terminal oxidase protein complex required for cellular respiration. The system involves a heme-mediated oxygen sensing mechanism that also was found to regulate the mitochondrial respiratory chain’s function as the powerhouse of the cell.

High School Student Finds Success in Dr. Vineet Gupta’s Lab

During the past three summers and, on as many days as she could during the school year, Ellora Sarkar left her typical teenage life behind and headed to the Gupta lab, where, under his guidance, she has been developing a novel, easy-to-use diagnostic test to detect TB in patients and pinpoint multidrug-resistant tuberculosis (MDR-TB), the classification of TB that is resistant to the two most powerful, first-line drugs for th
