FcγRIIB-Independent Mechanisms Controlling Membrane Localization of the Inhibitory Phosphatase SHIP in Human B Cells

2605 views | Apr 10 2018

Pauls SD et al. indicated that FcγRIIB is not uniquely able to promote membrane recruitment of SHIP, but rather modulates its function via formation of distinct signaling complexes. Membrane recruitment of SHIP via Syk-dependent mechanisms may be an important factor modulating immunoreceptor signaling. [Read the Full Post]

Susceptibility of porcine endogenous retrovirus to anti-retroviral inhibitors

775 views | Apr 09 2018

Argaw T et al. indicated that some of the licensed anti-retroviral drugs may be useful for controlling PERV infection. However, the efficacy at nanomolar concentrations put forward integrase inhibitors as a drug that has the potential to be useful in the event that xenotransplantation recipients have evidence of PERV transmission and replication.

Novel Akt activator SC-79 is a potential treatment for alcohol-induced osteonecrosis of the femoral head

1805 views | Apr 09 2018

Chen YX et al. showed that alcohol-induced ONFH is associated with suppression of p-Akt-Ser473 in the Akt/GSK3β/β-catenin signaling pathway in bone mesenchymal stem cells. We propose that SC-79 treatment to rescue Akt activation could be tested in the clinic as a potential therapeutic approach to preventing the development of alcohol-induced ONFH. [Read the Full Post]

1601 views | Apr 08 2018

Ji Y et al. provided new insights into a functional role of MKP-1 in oxidative stress-induced cell death by regulating ERK1/2 MAP kinase in intestinal epithelial cells. [Read the Full Post]

ABCB1 as predominant resistance mechanism in cells with acquired SNS-032 resistance

882 views | Apr 08 2018

Löschmann N et al. showed that ABCB1 expression represents the primary (sometimes exclusive) resistance mechanism in neuroblastoma cells with acquired resistance to SNS-032. Thus, ABCB1 inhibitors may increase the SNS-032 efficacy in ABCB1-expressing cells and prolong or avoid resistance formation. [Read the Full Post]

The Bub1-Plk1 kinase complex promotes spindle checkpoint signalling through Cdc20 phosphorylation

1133 views | Apr 07 2018

Jia L et al. showed that human checkpoint kinase Bub1 not only directly phosphorylates Cdc20, but also scaffolds Plk1-mediated phosphorylation of Cdc20. [Read the Full Post]

Synergistic effects of selective inhibitors targeting the PI3K/AKT/mTOR pathway or NUP214-ABL1 fusion protein in human Acute Lymphoblastic Leukemia

0 views | Apr 07 2018

Simioni C et al. found that co-targeting NUP214-ABL1 fusion gene and PI3K/Akt/mTOR signaling pathway could represent a new and effective pharmacological strategy to improve the outcome in NUP214-ABL1 positive T-ALL. [Read the Full Post]

Cancer-associated fibroblasts attenuate Cisplatin-induced apoptosis in ovarian cancer cells by promoting STAT3 signaling

1125 views | Apr 06 2018

Yan H et al. suggested that CAFs could activate the anti-apoptotic STAT3 signaling, thereby decrease the Cisplatin-induced apoptosis and promote chemoresistance in ovarian cancer. [Read the Full Post]

Neuroprotective effects of piperine on the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's disease mouse model.

0 views | Apr 06 2018

Yang W et al. showed that piperine exerts a protective effect on dopaminergic neurons via antioxidant, anti-apoptotic, and anti-inflammatory mechanisms in an MPTP-induced mouse model of PD [Read the Full Post]

In situ electrochemical evaluation of dsDNA interaction with the anticancer drug danusertib nitrenium radical product using the DNA-electrochemical biosensor

3306 views | Apr 05 2018

Diculescu VC et al. indicated the danusertib nitrenium cation radical redox metabolite was covalently attached to the C8 of guanine residues preventing their oxidation. An interaction mechanism of dsDNA-danusertib is proposed and the formation of the danusertib redox nitrenium radical metabolite-guanine adduct explained. [Read the Full Post]

Targeting Autophagy Sensitizes BRAF-Mutant Thyroid Cancer to Vemurafenib
