Anidulafungin-Induced Suicidal Erythrocyte Death

0 views | Nov 01 2017

Anidulafungin triggers hemolysis and eryptosis with cell shrinkage and phospholipid scrambling of the erythrocyte cell membrane, an effect in part due to Ca2+ entry and activation of p38 kinase. [Read the Full Post]

Inhibition of β-Catenin to Overcome Endocrine Resistance in Tamoxifen-Resistant Breast Cancer Cell Line

0 views | Oct 31 2017

Won HS et al. suggested that beta-catenin plays a role in tamoxifen-resistant breast cancer, and the inhibition of beta-catenin may be a potential target in tamoxifen-resistant breast cancer. [Read the Full Post]

Lee MJ, et al. demonstrated that PI3Kδ regulates Dectin-2 signaling and its dendritic cell function. [Read the Full Post]

Coordinate involvement of Nodal-dependent inhibition and Wnt-dependent activation in the maintenance of organizer-specific bmp2b in zebrafish

1055 views | Oct 30 2017

Xue Y et al. suggested that maintenance of organizer-specific bmp2b expression involves opposite and concerted regulation by Nodal and Wnt signaling. [Read the Full Post]

S100B impairs glycolysis via enhanced poly(ADP-ribosyl)ation of glyceraldehyde-3-phosphate dehydrogenase in rodent muscle cells

1148 views | Oct 30 2017

Hosokawa K et al. concluded that S100B as a humoral factor may impair glycolysis in muscle cells independent of insulin action, and the effect may be attributed to the inhibition of GAPDH activity from enhanced poly(ADP-ribosyl)ation of the enzyme. conclude that S100B as a humoral factor may impair glycolysis in muscle cells independent of insulin action, and the effect may be attributed to the inhibition of GAPDH activity from enhanced poly(ADP-ribosyl)ation of the enzyme.

Functional Effects of AKT3 on Aurora Kinase Inhibitor-induced Aneuploidy

0 views | Oct 29 2017

Noguchi K et al. suggested that AKT3 could repress the antiproliferative effects of AURKi, with a novel activity particularly suppressing the aneuploidy induction. [Read the Full Post]

Enhancement of macrophage inflammatory responses by CCL2 is correlated with increased miR-9 expression and downregulation of the ERK1/2 phosphatase Dusp6

628 views | Oct 29 2017

Carson WF 4th et al. indicated that CCL2 supports the classical activation of macrophages, with miR-9 mediated down-regulation of Dusp6 and enhanced ERK-mediated signal transduction possibly mediating this enhanced pro-inflammatory gene expression. [Read the Full Post]

Overcoming Resistance of Cancer Cells to PARP-1 Inhibitors with Three Different Drug Combinations

872 views | Oct 28 2017

Yalon M et al. showed that combination of vorinostat and ABT-888 could potentially prove useful for treatment of cancer with innate resistance to PARPis due to active HRR machinery, while the combination of vorinostat and 6-TG could potentially overcome innate or acquired resistance to PARPis due to secondary or reversal BRCA mutations, to decreased PARP-1 level or to increased expression of multiple drug resistant proteins.

Cancer-associated fibroblasts promote hepatocellular carcinoma metastasis through chemokine-activated hedgehog and TGF-β pathways

1033 views | Oct 28 2017

Liu J et al. found that CAF-secreted CCL2, CCL5, CCL7 and CXCL16 promote HCC metastasis through the coordinate activation of Hh and TGF-β pathways in HCC cells. [Read the Full Post]

Disulfiram overcomes bortezomib and cytarabine resistance in Down-syndrome-associated acute myeloid leukemia cells

625 views | Oct 26 2017

Bista R et al. provided evidence that DSF/Cu2+ overcomes Ara-C and BTZ resistance in cell lines from DS-AMKL patients. A novel mutation underlying BTZ resistance was detected that may identify BTZ-resistant patients, who may not benefit from treatment with CFZ or Ara-C, but may be responsive to DSF/Cu2+. Our findings support the clinical development of DSF/Cu2+ as a less toxic efficacious treatment approach in patients with relapsed/refractory DS-AMKL. [Read the Full Post]

MEK inhibitors block growth of lung tumours with mutations in ataxia-telangiectasia mutated

EMT is associated with, but does not drive resistance to ALK inhibitors among EML4-ALK non-small cell lung cancer

0 views | Oct 25 2017

Gower A et al. showed that EMT does not drive resistance to ALK inhibitors and HSP90 inhibition demonstrates more efficacy when further ALK inhibition may not. This study warrants more exploration of HSP90 inhibitors for ALK-positive patients who progress on 1st and 2nd line ALK inhibitor therapy. [Read the Full Post]
