How A Drug-Lead Compound Kills Cancer Cells By 'Starving' Them Of Energy, Preventing Tumor Formation
5/23/2012
A team of scientists from the National University of Singapore's (NUS) Department of Biological Sciences and Mechanobiology Institute have discovered how a drug-lead compound - a compound that is undergoing preclinical trials as a potential drug - can deprive cancer cells of energy and stop them from growing into a tumour. This drug-lead compound is named BPTES...
Lung Cancer CT Screening Guidelines Revised
