Research

In 2011, Reddy's research group made a significant breakthrough by revealing the existence of circadian clocks within human red blood cells (erythrocytes).[3] This discovery challenged prior assumptions that mammals lacked circadian clocks without DNA, RNA production, or protein production. The oscillations observed in red blood cells could be interpreted as a form of biochemical or chemical oscillation, extending over a prolonged 24-hour timeframe.[4] The impact of this work garnered recognition from notables like Sir Christopher Dobson, who drew parallels to established short-period oscillations in chemical systems.[4] The research received commendation within the circadian rhythms research community, with peers describing it as 'exceptional' in post-publication peer reviews on Faculty of 1000.[5][6][7][8]

In collaboration with the research team led by Andrew Millar in Edinburgh, Reddy's group extended their contributions by demonstrating 24-hour oscillations that manifest in marine algae without necessitating RNA production.[9] This groundbreaking finding represented the inaugural display of circadian rhythms in higher organisms without the involvement of new RNA formation.

In 2012, Reddy's research group unveiled a comprehensive revelation: redox circadian oscillations are universally present across evolutionary epochs, spanning from bacteria to humans. This insight was enabled by the utilization of peroxiredoxin proteins, a novel molecular perspective into circadian dynamics.[10] Michael Rosbash, a Nobel laureate, acknowledged the significance of this contribution, highlighting how it challenged conventional animal models that emphasized PER-CLK transcription. Rosbash underscored the emerging consideration of metabolism and peroxiredoxin hyperoxidation in the orchestration of circadian rhythms.[11]

In 2018, Reddy's team showed the intimate links between core glucose metabolism and circadian transcriptional oscillations, as well as non-canonical circadian rhythms in clock-less fruit fly cells.[12] These findings show that there continues to be an incomplete understanding of molecular circadian rhythms in a range of organisms.[13]

Controversy

In December 2019, Reddy underwent a hearing at the Medical Practitioners Tribunal regarding alleged overpayment by both University College of London and the University of Cambridge.[14] Reddy was suspended for nine months from the medical practice in the United Kingdom; the case is subject to an appeal in the High Court, and sanctions have not yet been applied.
