Coronary atherosclerosis in end-stage idiopathic dilated cardiomyopathy: an innocent bystander?
One-fourth of the patients with end-stage IDCM hearts excised at HTx (all with angiographically normal coronary arteries at first diagnosis) have bystander critical coronary atherosclerosis whose functional role (if any) deserves investigation.
Our results provide the first evidence that dMyc oncoprotein is required in lgl tumour suppressor mutant tissue to promote invasive overgrowth in larval and adult epithelial tissues. Moreover, we show that dMyc abundance inside versus outside the mutant clones plays a key role in driving neoplastic overgrowth.
