IgG subclasses determine pathways of anaphylaxis in mice

2174 views | Feb 27 2017

Beutier H et al. proposed that the differential expression of inhibitory FcγRIIB on myeloid cells and its differential binding of IgG subclasses controls the contributions of mast cells, basophils, neutrophils, and macrophages to IgG subclass-dependent anaphylaxis. Collectively, our results unravel novel complexities in the involvement and regulation of cell populations in IgG-dependent reactions in vivo. [Read the Full Post]

Suppressing Cyclooxygenase-2 prevents nonalcoholic steatohepatitis and inhibits apoptosis of hepatocytes that are involved in the Akt/p53 signal pathway

1125 views | Feb 27 2017

Wu J, et al.'s findings suggested that suppressing COX-2 can improve steatohepatitis by inhibiting hepatocyte apoptosis in mice via regulating the Akt/p53 pathway. Celecoxib treatment may be a favorable treatment option for NASH. [Read the Full Post]

1415 views | Feb 27 2017

Chen H, et al.'s results establish the importance of SIK3 as a mitotic regulator and underscore the potential of SIK3 as a druggable antimitotic target. [Read the Full Post]

CDK4/6 Inhibition Controls Proliferation of Bladder Cancer and Transcription of RB1

876 views | Feb 26 2017

Sathe A, et al. provide preclinical evidence that CDK4/6 inhibition is a potential therapeutic strategy for retinoblastoma positive bladder cancer that probably acts by negatively regulating retinoblastoma transcription. [Read the Full Post]

Epothilone B induces apoptosis and enhances apoptotic effects of ABT-737 on human cancer cells via PI3K/AKT/mTOR pathway

1001 views | Feb 25 2017

These data indicate that ABT-737 may be a pertinent sensitizer to epothilone B, and the strategy of combining epothilone B with ABT-737 appears to be an attractive option for overcoming the resistance and neurotoxicity of epothilone B. [Read the Full Post]

X66, a novel N-terminal heat shock protein 90 inhibitor, exerts antitumor effects without induction of heat shock response

1394 views | Feb 25 2017

The HSP90 inhibitory action and the potent antitumor activity, with the anti-HSR action, promise X66 a novel HSP90-targeted agent, which merits further research and development. [Read the Full Post]

Solitary inhibition of the breast cancer resistance protein (BCRP) efflux transporter results in a clinically significant drug-drug interaction with rosuvastatin by causing up to a two-fold increase in statin exposure

1957 views | Feb 25 2017

Elsby R, et al.'s result shows that solitary inhibition of the intestinal BCRP transporter can result in clinically significant DDIs with rosuvastatin, causing up to a maximum 2-fold increase in exposure, which may warrant statin dose adjustment in clinical practice [Read the Full Post]

Relative cytotoxic potencies and cell death mechanisms of α1 -adrenoceptor antagonists in prostate cancer cell lines

1703 views | Feb 24 2017

Prazosin and doxazosin demonstrated cytotoxic actions on both castration-resistant PC-3 and androgen-sensitive LNCap prostate cancer cells. The mechanisms involved included changes in a number of proliferation and apoptosis regulatory proteins. The role of autophagy depended on the cell type, but contributed to cell death in PC3 cells.
