Cryo-EM structure studies of the human VPS10 domain-containing receptor SorCS3.

The human VPS10 domain-containing receptor SorCS3 belongs to the Vps10p-domain receptor family and is an important receptor for regulating normal cellular functions via protein sorting. Here, we determined the cryo-EM structure of the full-length SorCS3 receptor and further found that there were at least three distinct conformations (monomer, M-shaped dimer and N-shaped dimer) of SorCS3 in the apo state. The differences between the two dimer conformations were caused by PKD1-2 assembly.

Bazedoxifene Attenuates Abdominal Aortic Aneurysm Formation Downregulation of Interleukin-6/Glycoprotein 130/Signal Transducer and Activator of Transcription 3 Signaling Pathway in Apolipoprotein E-Knockout Mice.

Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease characterized by aortic dilatation and predominantly affects an elderly population. Accumulating evidence suggests that Interleukin-6 (IL-6) and the signal transducer and activator of transcription 3 (STAT3) play an important role in formation of AAAs. However, it remains unclear whether Bazedoxifene (BAZ) could suppress the activation of IL-6/GP130/STAT3 in vascular cells and the formation of AAA.

Inhibition of Interleukin-6/glycoprotein 130 signalling by Bazedoxifene ameliorates cardiac remodelling in pressure overload mice.

The role of IL-6 signalling in hypertensive heart disease and its sequelae is controversial. Our group demonstrated that Bazedoxifene suppressed IL-6/gp130 signalling in cancer cells but its effect on myocardial pathology induced by pressure overload is still unknown. We explored whether Bazedoxifene could confer benefits in wild-type C57BL/6J mice suffering from transverse aortic constriction (TAC) and the potential mechanisms in H9c2 myoblasts.

Bazedoxifene exhibits growth suppressive activity by targeting interleukin-6/glycoprotein 130/signal transducer and activator of transcription 3 signaling in hepatocellular carcinoma.

The interleukin (IL)-6/glycoprotein (GP)130/signal transducer and activator of transcription (STAT)3 pathway is emerging as a target for the treatment of hepatocellular carcinoma. IL-6 binds to IL-6R, forming a binary complex, which further combines with GP130 to transduce extracellular signaling by activating STAT3. Therefore, blocking the interaction between IL-6 and GP130 may inhibit the IL-6/GP130/STAT3 signaling pathway and its biological effects.

Anticancer drugs-related QTc prolongation, torsade de pointes and sudden death: current evidence and future research perspectives.

Anticancer drugs may have proarrhythmic effects including drug-induced QT interval prolongation, which is of particular importance because it can lead to a fatal polymorphic ventricular tachycardia termed torsade de pointes (TdP). QT interval prolongation and TdP are rare life-threatening untoward effects of anticancer therapy, particularly with arsenic trioxides and anthracyclines, and even some novel molecular targeted drugs touted as 'tumor specific'. Several factors that affect myocardial repolarization can further increase the risk of TdP.

Ursolic acid prevents angiotensin II-induced abdominal aortic aneurysm in apolipoprotein E-knockout mice.

Background And Aims: Abdominal aortic aneurysms (AAA) is a chronic inflammatory disease in which signal transducer and activator of transcription 3 (STAT3), and disintegrin and metalloproteinase 17 (ADAM17) play important roles. However, it remains unclear whether ursolic acid (UA), a natural pentacyclic triterpenoid carboxylic acid, can have an impact on STAT3 and ADAM17 and hence influence the formation of AAA. The objective of this study was to characterize the potential effect of UA on the pathogenesis of AAA and on STAT3 and ADAM17.

Sapylin promotes wound healing in mouse skin flaps.

Seroma formation is one of the most common complications after modified radical mastectomy. Sapylin is an agent used to reduce seroma formation following breast cancer surgery. In this article, we aimed to identify the potential mechanism by which Sapylin reduced seroma formation.
