CD146 expression and its close relationship to tumor progression in systemic malignancies besides gall bladder...

Recent data suggest that CD146 may be involved in tumor development and may influence tumor prognosis in a number of systemic tumors besides gall bladder carcinomas. For instance, CD146 augments the development and progression of gastric carcinomas. It performs this function by accentuating epithelial mesenchymal transition (Liu et al., Int J Mol Sci 13:6399-6406, 2012). CD146 thus points towards a poor clinical outcome in gastric malignancies. An increase in gastric tissue vimentin is seen with an increase in CD146 levels. Similarly, around 8.7 % of lung adenocarcinomas express CD146. A decreased 5-year overall survival rate is seen following lung resection of pulmonary adenocarcinomas in male patients who express CD146 (Zeng et al., Proc Natl Acad Sci USA 109:1127-1132; 2012).
