Buparlisib plus fulvestrant versus placebo plus fulvestrant in postmenopausal, hormone receptor-positive, HER2-negative, advanced breast cancer (BELLE-2): a randomised, double-blind, placebo-controlled, phase 3 trial

168 views | Oct 25 2019

Baselga J et al. showed that PI3K inhibition combined with endocrine therapy is effective in postmenopausal women with endocrine-resistant, hormone receptor-positive and HER2-negative advanced breast cancer. Use of more selective PI3K inhibitors, such as α-specific PI3K inhibitor, is warranted to further improve safety and benefit in this setting. No further studies are being pursued because of the toxicity associated with this combination. [Read the Full Post]

Trichostatin A and 5-Aza-2'-Deoxycytidine influence the expression of cold-induced genes in Arabidopsis

255 views | Oct 22 2019

Song Y et al. showed this result will advance our understanding of plant freezing responses and may provide a helpful strategy for cold tolerance improvement in crops. [Read the Full Post]

Exogenous mesenchymal stem cells affect the function of endogenous lung stem cells (club cells) in phosgene-induced lung injury

0 views | Oct 21 2019

Ye K et al. showed that MSCs reduced the secretion of club cells. And MSCs enhanced the proliferation of club cells partly via activating the Notch signaling pathway, which promoted lung injury repair. [Read the Full Post]

The Phosphatidylinositol 3-Kinase Pathway as a Potential Therapeutic Target in Bladder Cancer

105 views | Oct 21 2019

Zeng SX et al. provided new insights into the therapeutic potential of targeting the PI3K pathway for the treatment of bladder cancer. [Read the Full Post]

Prolonged Idasanutlin (RG7388) Treatment Leads to the Generation of p53-Mutated Cells

135 views | Oct 20 2019

Skalniak L et al. showed that although idasanutlin presents much improved activities compared to its precursor, it displays the similar weaknesses, which are limited elimination of cancer cells and the generation of p53-mutated drug-resistant subpopulations. [Read the Full Post]

The anti-caspase inhibitor Q-VD-OPH prevents AIDS disease progression in SIV-infected rhesus macaques

238 views | Oct 20 2019

Laforge M et al. demonstrated that Q-VD-OPH injection in SIV-infected RMs may represent an adjunctive therapeutic agent to control HIV infection and delaying disease progression to AIDS. [Read the Full Post]

Dorsomorphin induces cancer cell apoptosis and sensitizes cancer cells to HSP90 and proteasome inhibitors by reducing nuclear heat shock factor 1 levels

133 views | Oct 19 2019

Li N et al. indicated that dorsomorphin is an HSF1 inhibitor. It induces cancer cell apoptosis, sensitizes cancer cells to both HSP90 and proteasome inhibitors, and suppresses HSP upregulation by these drugs, which may prevent the development of drug resistance. Hence, dorsomorphin and its derivates may serve as potential precursors for developing drugs against cancer. [Read the Full Post]

BI-2536 and BI-6727, dual Polo-like kinase/bromodomain inhibitors, effectively reactivate latent HIV-1

176 views | Oct 19 2019

Gohda J et al. found that BI-2536 synergistically activates the latent provirus in combination with SAHA, a histone deacetylase inhibitor, or the non-tumour-promoting phorbol ester prostratin. Our findings strongly suggest that BI-2536 and BI-6727 are potent LRAs for the "shock and kill" HIV-1 eradication strategy. [Read the Full Post]
