Cotargeting BET proteins overcomes resistance arising from PI3K/mTOR blockade-induced protumorigenic senescence in colorectal cancer.

Therapeutics targeting the phosphatidylinositol 3-kinase/mammalian target of rapamycin (PI3K/mTOR) pathway initially produce potent antitumor effects, but resistance frequently occurs. Using a phosphoproteome analysis, we found that colorectal cancer (CRC) cells exhibit resistance against PI3K/mTOR inhibition through feedback activation of multiple receptor tyrosine kinases, and their downstream focal adhesion kinase, Src and extracellular signal-regulated kinases signaling. Unexpectedly, PI3K/mTOR blockade causes senescence, mediated by the activation of the stress kinase p38.

Attractor landscape analysis of the cardiac signaling network reveals mechanism-based therapeutic strategies for heart failure.

Apoptosis and hypertrophy of cardiomyocytes are the primary causes of heart failure (HF), a global leading cause of death, and are regulated through the complicated intracellular signaling network, limiting the development of effective treatments due to its complexity. To identify effective therapeutic strategies for HF at a system level, we develop a large-scale comprehensive mathematical model of the cardiac signaling network by integrating all available experimental evidence. Attractor landscape analysis of the network model identifies distinct sets of control nodes that effectively suppress apoptosis and hypertrophy of cardiomyocytes under ischemic or pressure overload-induced HF, the two major types of HF.

Effect of Antioxidant Water on the Bioactivities of Cells.

It has been reported that water at the interface of a hydrophilic thin film forms an exclusion zone, which has a higher density than ordinary water.
