Protein carbonylation as a possible way to modulate breast cancer cell proliferation

MiR-6165 Dysregulation in Breast Cancer and Its Effect on Cell Proliferation and Migration

Background: ncRNAs have been identified as oncogenic drivers and tumor suppressors in any type of cancer. Although many classes of ncRNAs have been reported, most studies have been performed on microRNAs (miRNAs). miRNAs can regulate several target genes and affect important processes such as homeostasis, angiogenesis, cell proliferation, differentiation, and apoptosis. Located in the p75NTR ge...

Effects of berberine on proliferation, cell cycle distribution and apoptosis of human breast cancer T47D and MCF7 cell lines

Objective(s):Berberine, a naturally occurring isoquinoline alkaloid, has shown antitumor properties in some in vitro systems. But the effect of berberine on breast cancer has not yet been completely studied. In this study, we evaluated anticancer properties of berberine in comparison to doxorubicin. Materials and Methods: The antiproliferative effects of berberine and doxorubicin alone and in ...

Protein kinase A activates the Hippo pathway to modulate cell proliferation and differentiation.

The Hippo tumor suppressor pathway plays an important role in tissue homeostasis that ensures development of functional organs at proper size. The YAP transcription coactivator is a major effector of the Hippo pathway and is phosphorylated and inactivated by the Hippo pathway kinases Lats1/2. It has recently been shown that YAP activity is regulated by G-protein-coupled receptor signaling. Here...

Cell Proliferation Signal Strength To Differentially Modulate T Surfactant Protein A Integrates Activation

Protein carbonylation.

Protein carbonylation is a type of protein oxidation that can be promoted by reactive oxygen species. It usually refers to a process that forms reactive ketones or aldehydes that can be reacted by 2,4-dinitrophenylhydrazine (DNPH) to form hydrazones. Direct oxidation of side chains of lysine, arginine, proline, and threonine residues, among other amino acids, in the ‘‘primary protein carbonylat...
