Antitumor activity of miR-34a in peritoneal mesothelioma relies on c-MET and AXL inhibition: persistent activation of ERK and AKT signaling as a possible cytoprotective mechanism

852 views | Feb 06 2018

El Bezawy R et al. showed impressive inhibitory effects induced by miR-34a on DMPM cell proliferation, invasion, and growth in immunodeficient mice strongly suggest the potential clinical utility of a miR-34a-replacement therapy for the treatment of such a still incurable disease. On the other hand, we provide the first evidence of a potential cytoprotective/resistance mechanism that may arise towards miRNA-based therapies through the persistent activation of RTK downstream signaling.

Epigenetic regulation of glucose-stimulated osteopontin (OPN) expression in diabetic kidney

779 views | Feb 04 2018

Cai M et al. concluded that glucose is a potent inducer of histone acetylation and methylation, which in turn leads to upregulation of OPN gene expression. Treatment targeting histone marks may therefore represent an alternative method to protect kidneys from deleterious effects of glucose. [Read the Full Post]

3D microtumors in vitro supported by perfused vascular networks

1841 views | Feb 02 2018

Sobrino A et al. indicated that tumors in the VMT show strong metabolic heterogeneity when imaged using NADH Fluorescent Lifetime Imaging Microscopy and, compared to their surrounding stroma, many show a higher free/bound NADH ratio consistent with their known preference for aerobic glycolysis. The VMT platform provides a unique model for studying vascularized solid tumors in vitro. [Read the Full Post]
