Ferroptosis is an autophagic cell death process

393 views | Jul 12 2018

Gao M et al. indicated that ferroptosis is an autophagic cell death process, and NCOA4-mediated ferritinophagy supports ferroptosis by controlling cellular iron homeostasis. [Read the Full Post]

Hypoxia potentiates the cytotoxic effect of piperlongumine in pheochromocytoma models

574 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

358 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.

The afatinib resistance of in vivo generated H1975 lung cancer cell clones is mediated by SRC/ERBB3/c-KIT/c-MET compensatory survival signaling

673 views | Jul 11 2018

Booth L et al. showed the inhibition of ERBB3 signaling via both blockade of SRC and ERBB1 results in tumor cell death. [Read the Full Post]

Inhibiting PLK1 induces autophagy of acute myeloid leukemia cells via mammalian target of rapamycin pathway dephosphorylation

Tao YF et al. provided new insights into the molecular mechanism of PLK1 in regulating autophagy. [Read the Full Post]

Fibroblastic foci, covered with alveolar epithelia exhibiting epithelial-mesenchymal transition, destroy alveolar septa by disrupting blood flow in idiopathic pulmonary fibrosis

545 views | Jul 10 2018

Yamaguchi M et al. showed that inhibition of transforming growth factor-β signaling, which can suppress EMT of the alveolar epithelial cells in vitro, is a potential strategy for treating IPF. [Read the Full Post]

HIV-1 gp120 Glycoprotein Interacting with Dendritic Cell-specific Intercellular Adhesion Molecule 3-grabbing Non-integrin (DC-SIGN) Down-Regulates Tight Junction Proteins to Disrupt the Blood Retinal Barrier and Increase Its Permeability

Qian YW et al. elucidated a novel mechanism by which HIV, type 1 invades ocular tissues and provides additional insights into the translocation or invasion process of ocular complication-associated pathogens. [Read the Full Post]

Activation of IGF1R/p110β/AKT/mTOR confers resistance to α-specific PI3K inhibition

1193 views | Jul 08 2018

Leroy C, et al. demonstrated that the IGF1R/p110β/AKT/mTOR axis confers resistance to BYL719 in PIK3CA mutant breast cancers. This provides a rationale for the combined targeting of p110α with IGF1R or p110β in patients with breast tumors harboring PIK3CA mutations. [Read the Full Post]
