Anti-apoptotic Bcl-XL but not Mcl-1 contributes to protection against virus-induced apoptosis

436 views | Jul 17 2018

Ohmer M et al. showed that Mcl-1 is dispensable for the regulation of apoptosis during infection with different large DNA viruses, either because the viruses replace its function (in fibroblasts and epithelial cells) or because the pro-apoptotic activity generated by the infection appears not to be blocked by it (in macrophages).

Selective Sparing of Human Tregs by Pharmacologic Inhibitors of the Phosphatidylinositol 3-Kinase and MEK Pathways

373 views | Jul 16 2018

Zwang NA et al. suggested less functional reliance on PI3K and MEK signaling in Tregs compared with conventional CD4(+) and CD8(+) lymphocytes. Therefore, the PI3K and MEK pathways are attractive pharmacologic targets for transplantation and treatment of autoimmunity. [Read the Full Post]

PI3Kα isoform-dependent activation of RhoA regulates Wnt5a-induced osteosarcoma cell migration

0 views | Jul 15 2018

Zhang A et al. demonstrated that RhoA acts as the downstream of PI3K/Akt signaling (specific PI3Kα, Akt1 and Akt2 isoforms) and mediated Wnt5a-induced the migration of osteosarcoma cells. [Read the Full Post]

Ribonucleotide Reductase Catalytic Subunit M1 (RRM1) as a Novel Therapeutic Target in Multiple Myeloma

426 views | Jul 15 2018

Sagawa M et al. demonstrated that RRM1 is a novel therapeutic target in multiple myeloma in the preclinical setting and provide the basis for clinical evaluation of RRM1 inhibitor, alone or in combination with DNA-damaging agents, to improve patient outcome in multiple myeloma.

Hypoxia potentiates the cytotoxic effect of piperlongumine in pheochromocytoma models

844 views | Jul 12 2018

Bullova P et al. reported for the first time that PL mediates PHEO cell death by activating both apoptosis and necroptosis in vitro and in vivo. This effect is magnified in hypoxic conditions, making PL a promising potential candidate for use as a therapeutic option for patients with PHEO/PGL, including those with SDHB mutations.

Role and mechanism of PTEN in adiponectin-induced osteogenesis in human bone marrow mesenchymal stem cells

531 views | Jul 11 2018

Liu X et al. suggested that APN enhanced osteogenic differentiation of hBMSCs in vitro partially by inhibiting PTEN expression. APN could be a therapeutic agent in tissue regeneration engineering and bone regeneration by inhibiting PTEN expression and then promoting the osteogenic differentiation of hBMSCs.
