Perturbed ER homeostasis by IGF-IIR α promotes cardiac damage under stresses
In this study, we investigate the molecular mechanism and contribution of IGF-IIRα in endoplasmic reticulum stress induction in the heart under doxorubicin-induced cardiotoxicity. Using in vitro H9c2 cells, in vivo transgenic rat cardiac tissues, siRNAs against CHOP, chemical ER chaperone PBA, and western blot experiments, we found that IGF-IIRα overexpression enhanced ER stress markers ATF4, ATF6, IRE1α, and PERK which were further aggravated by DOX treatment. This was accompanied by a significant perturbation in stress-associated MAPKs such as p38 and JNK. Interestingly, PARKIN, a stress responsive cellular protective...

Forskolin regulates retinal endothelial cell permeability through TLR4 actions in vitro
Mol Cell Biochem. 2021 Aug 28. doi: 10.1007/s11010-021-04252-9. Online ahead of print.ABSTRACTTo investigate whether forskolin, a protein kinase A agonist, regulates toll-like receptor 4 actions on retinal endothelial cell permeability in vitro. We also evaluated whether PKA could regulate TLR4 signaling independent of exchange protein activated by cAMP in REC in culture. REC were grown in normal (5 mM) or high (25 mM) glucose. Cells were treated with forskolin to increase PKA levels, siRNA against TLR4, siRNA against myeloid differentiation primary response 88, siRNA against translocating chain associated membrane protein...

Effects of miR-202-5p silencing PIK3CA gene expression on proliferation, invasion, and epithelial-mesenchymal transition of cervical cancer SiHa cells through inhibiting PI3K/Akt/mTOR signaling pathway activation
In conclusion, the overexpression of miR-202-5p can suppress PIK3CA gene expression and the activation of PI3K/Akt/mTOR signaling pathway to suppress the proliferation, invasion, and EMT of cervical cancer.PMID:34244973 | DOI:10.1007/s11010-021-04211-4

Hepatocyte steatosis inhibits hepatitis B virus secretion via induction of endoplasmic reticulum stress
Mol Cell Biochem. 2021 May 13. doi: 10.1007/s11010-021-04143-z. Online ahead of print.ABSTRACTThe effects of hepatocyte steatosis on hepatitis B virus (HBV) DNA replication and HBV-related antigen secretion are incompletely understood. The aims of this study are to explore the effects and mechanism of hepatocyte steatosis on HBV replication and secretion. Stearic acid (SA) and oleic acid (OA) were used to induce HepG2.2.15 cell steatosis in this study. The expressions of glucose-regulated protein 78 (GRP78), phosphorylation of protein kinase R-like endoplasmic reticulum (ER) kinase (p-PERK), and eukaryotic translation init...

Activation of AMPK inhibits Galectin-3-induced pulmonary artery smooth muscle cells proliferation by upregulating hippo signaling effector YAP
Mol Cell Biochem. 2021 Apr 2. doi: 10.1007/s11010-021-04131-3. Online ahead of print.ABSTRACTGalectin-3(Gal-3) is an effective regulator in the pathological process of pulmonary arterial hypertension (PAH). However, the detailed mechanisms underlying Gal-3 contribution to PAH are not yet entirely clear. The aim of the present study was to explore these issues. Proliferation of rat pulmonary arterial smooth muscle cells (PASMCs) was determined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Small interfering RNA (siRNA) was applied to silence the expression of yes-associated protein (YAP) a...
