We previously confirmed the targeting of high-mobility group box 1 (HMGB1) by miR-25. This project aims to further investigate whether miR-25 improves myocardial ischemia-reperfusion injury (IRI) in vivo by targeting HMGB1. ⋯ MiR-25 mitigated myocardial IRI-induced damage by targeting HMGB1.

Rapamycin is a type of immunosuppressive agent that acts through inhibition of mammalian target of rapamycin (mTOR). Hepatopulmonary syndrome (HPS) is a lethal complication in cirrhotic patients. It is characterized by hypoxia and increased intrapulmonary shunts, in which pulmonary inflammation and angiogenesis play important roles. The current study aimed to evaluate the effect of rapamycin on HPS using the experimental model of common bile duct ligation (CBDL)-induced cirrhosis in rats. ⋯ High-dose rapamycin ameliorates HPS in cirrhotic rats as evidenced by the alleviated hypoxia and decreased intrapulmonary shunts. Downregulation of the mTOR/P70S6K, NFκB, and VEGF signaling pathways might play a key role.

Lung cancer (LC) is a major killer disease globally. This situation is further supported by yearly increase in new LC cases and its poor 5-year survival which is less than 15%. Although a large percentage of LC cases have been attributed to smoking, a considerable amount of nonsmokers also develops this disease, thereby suggesting a genetic and/or epigenetic undertone to LC development. ⋯ Therefore, this review will discuss important ncRNAs, namely miRNA, lncRNA, and circRNA in LC progression. Paracrine effect of exosomal ncRNA will be also reviewed. In addition, the prospect of these ncRNAs in enhancing better LC treatment will be highlighted as well.

Immunosuppressant-related acceleration of fibrosis has been documented in chronic hepatitis C (CHC) patients who receive organ transplantation (Tx), and sustained virological response (SVR) rates for these patients by pegylated interferon (IFN)-based therapy are generally poor and associated with unfavorable safety profiles. In addition, IFN treatment varies by patient and poses a high risk of post-renal Tx graft rejection. This study was aimed to investigate the efficacy and safety of all oral direct acting antivirals (DAAs) for CHC patients following organ Tx. ⋯ Highly responsive treatment and favorable tolerability were achieved by all oral DAAs in this difficult-to-treat patient population.
