miR-206 regulates cisplatin resistance and EMT in human lung adenocarcinoma cells partly by targeting MET

431 views | May 14 2018

Chen QY et al. found that miR-206 could also sensitize A549/DDP cells to cisplatin in mice model. Taken together, our study implied that activation of miR-206 or inactivation of its target gene pathway could serve as a novel approach to reverse cisplatin resistance in lung adenocarcinomas cells.

Activation of the Chicken Anemia Virus Apoptin Protein by Chk1/2 Phosphorylation Is Required for Apoptotic Activity and Efficient Viral Replication

484 views | May 13 2018

Kucharski TJ et al. determined that checkpoint kinase 1 and 2 signaling is important for apoptin regulation and is a likely feature of both tumor cells and host cells producing virus progeny. Inhibition of checkpoint signaling prevents apoptin toxicity in tumor cells and attenuates CAV replication, suggesting it may be a future target for antiviral therapy. [Read the Full Post]

0 views | May 12 2018

Yun T et al. found that HDAC inhibitors can induce p53 acetylation at lysine 120, which in turn enhances mitochondrion-mediated apoptosis through transcriptional up-regulation of Apaf-1. [Read the Full Post]

Investigating proteasome inhibitors as potential adjunct therapies for experimental cerebral malaria

536 views | May 11 2018

Howland SW et al. reported here that bortezomib, which has been associated with neurological adverse events, accelerated death in ECM-infected mice. [Read the Full Post]

Gp130-mediated STAT3 activation by S-propargyl-cysteine, an endogenous hydrogen sulfide initiator, prevents doxorubicin-induced cardiotoxicity

Wu J et al. offered a novel molecular basis and therapeutic strategy of H2S donor for the treatment of heart failure. [Read the Full Post]

Identification of TG100-115 as a new and potent TRPM7 kinase inhibitor, which suppresses breast cancer cell migration and invasion

360 views | May 10 2018

Song C et al. indicated that TG100-115 can be used as a potent TRPM7 kinase inhibitor and a potent inhibitor of breast cancer cell migration. [Read the Full Post]

Therapeutic implication of HER2 in advanced biliary tract cancer

813 views | May 10 2018

Nam AR et al. suggested that HER2 could be a therapeutic target, and that a HER2-targeting strategy should be developed further in patients with HER2-positive advanced BTC. [Read the Full Post]

Increased translocation of antigens to endosomes and TLR4 mediated endosomal recruitment of TAP contribute to nicotine augmented cross-presentation

402 views | May 09 2018

Wang YY et al. suggested that increased recruitment of TAP to Ag-containing vesicles contributes to the superior cross-presentation efficacy of α7 nAchR activated DCs. [Read the Full Post]

Dihydroartemisinin restricts hepatic stellate cell contraction via an FXR-S1PR2-dependent mechanism

399 views | May 09 2018

Xu W et al. suggested that DHA could restrict HSC contraction through modulating FXR/S1PR2 pathway-mediated Ca(2+) -dependent and Ca(2+) -sensitization signaling. Our discoveries make DHA a potential candidate for portal hypertension. [Read the Full Post]

A repressive role of enhancer of zeste homolog 2 in 11β-hydroxysteroid dehydrogenase type 2 expression in the human placenta

924 views | May 08 2018

Zuo R et al. found that enhancer of zeste homolog 2 (EZH2) accounts for the silence of 11β-HSD2 expression via trimethylation of histone H3 lysine 27 at the promoter of the 11β-HSD2 gene. [Read the Full Post]

Anandamide Suppresses Proinflammatory T Cell Responses In Vitro through Type-1 Cannabinoid Receptor-Mediated mTOR Inhibition in Human Keratinocytes

386 views | May 08 2018

Chiurchiù V et al. demonstrated that AEA suppresses highly pathogenic T cell subsets through CB1-mediated mammalian target of rapamycin inhibition in human keratinocytes. Thus, it can be speculated that the latter pathway might be beneficial to the physiological function of the skin, and can be targeted toward inflammation-related skin diseases. [Read the Full Post]

Oncogenic epithelial cell-derived exosomes containing Rac1 and PAK2 induce angiogenesis in recipient endothelial cells

0 views | May 07 2018

Gopal SK et al. demonstrated for the first time that oncogenic cells undergoing EMT can communicate with endothelial cells via exosomes, and establish exosomal Rac1/PAK2 as angiogenic promoters that may function from early stages of the metastatic cascade. [Read the Full Post]
