LncRNA GAS5 restrains ISO-induced cardiac fibrosis by modulating mir-217 regulation of SIRT1.

Considering the effect of SIRT1 on improving myocardial fibrosis and GAS5 inhibiting occurrence and development of myocardial fibrosis at the cellular level, the aim of the present study was to investigate whether LncRNA GAS5 could attenuate cardiac fibrosis through regulating mir-217/SIRT1, and whether the NLRP3 inflammasome activation was involved in this process. Isoprenaline (ISO) was given subcutaneously to the male C57BL/6 mice to induce myocardial fibrosis and the AAV9 vectors were randomly injected into the left ventricle of each mouse to overexpress GAS5. Primary myocardial fibroblasts (MCFs) derived from neonatal C57BL/6 mice and TGF-β1 were used to induce fibrosis.

Presently, suspected breast masses assessed as Breast Imaging-Reporting and Data System (BI-RADS) grade 4 provide a wide range of positive predictive values. Moreover, subcategories (4a, 4b, and 4c) are still under consideration as the diagnostic criteria are neither comprehensive nor objective.

SIRT1 activation attenuates cardiac fibrosis by endothelial-to-mesenchymal transition.

Endothelial-to-mesenchymal transition (EndMT) is closely related to the pathogenesis of various diseases, including cardiac fibrosis. Transforming growth factor (TGF)-β1 strongly induces EndMT, and sirtuin 1 (SIRT1) may play vital roles in TGF-β/Smad pathway inhibition. This study aimed to determine whether SIRT1 activation inhibits EndMT, thereby attenuating cardiac fibrosis.

Type 2 diabetic mellitus (T2DM) has reached pandemic status and shows no signs of abatement. Diabetic neuropathic pain (DNP) is generally considered to be one of the most common complications of T2DM, which is also recognized as one of the most difficult types of pain to treat. As one kind of peripheral neuropathic pain, DNP manifests typical chronic neuralgia symptoms, including hyperalgesia, allodynia, autotomy, and so on.

Treatment with angiotensin-(1-9) alleviates the cardiomyopathy in streptozotocin-induced diabetic rats.

Diabetic cardiomyopathy, a disorder of the heart muscle in diabetic patients, is one of the major causes of heart failure. We hypothesized that angiotensin-(1-9) [Ang-(1-9)] attenuates cardiomyopathy in streptozotocin (STZ)-induced diabetic rats. Rats were injected with a single intraperitoneal injection of STZ (55 mg/kg body weight) to induced diabetic cardiomyopathy.

The Apelin-APJ axis is an endogenous counterinjury mechanism in experimental acute lung injury.

Background: Although the mechanisms and pathways mediating ARDS have been studied extensively, less attention has been given to the mechanisms and pathways that counteract injury responses. This study found that the apelin-APJ pathway is an endogenous counterinjury mechanism that protects against ARDS.

Methods: Using a rat model of oleic acid (OA)-induced ARDS, the effects of ARDS on apelin and APJ receptor expressions and on APJ receptor binding capacity were examined.
