The trio at the centre of the scandal are Professor Ravi Kambadur, an India-trained New Zealander who was with the Nanyang Technological University (NTU), Dr Mridula Sharma, who was associate professor at the National University of Singapore's (NUS) Yong Loo Lin School of Medicine and former NTU researcher Sudarsanareddy Lokireddy.
Their work at the Singapore research institutes focused on myostatin - a protein that regulates muscle growth in humans and animals, whose suppression the researchers claimed could keep people in "fat-burning mode" and let them shed kilos.
Prof Kambadur, 54, was set to make waves in the world of biomedical research, as leader of one of the four teams awarded up to SGD10 million each in research grants in 2009.
Dr Sharma is no longer at NUS and Dr Lokireddy has had his PhD from NTU revoked.

NTU said its investigations in December last year led to three myostatin papers published in 2011 and 2012 being retracted.
Three more papers published from 2012 to 2014, based on research funded by the Agency for Science, Technology and Research (A*Star) and the National Research Foundation (NRF), are now being retracted from the journals Molecular Endocrinology and Journal of Biological Chemistry.
Retraction Watch, a website that monitors retractions of scientific publications, reported that the falsifications also happened in Dr Lokireddy's NTU doctoral thesis.
In 2012, his team reported a discovery of reprogramming skin cells to help slow loss of muscle mass in the elderly.
They had found that by blocking the protein myostatin, muscle growth could be enhanced and fat utilization in the body could be increased.
The research is now being called into question after investigation by NTU said that data from laboratory experiments had been falsified, the report said.
NTU said that "disciplinary proceedings" are being taken against other researchers and that Prof Kambadur's research students will be re-assigned to appropriate supervisors.
