Present in more than one billion adults, hypertension is the most significant modifiable risk factor for mortality resulting from cardiovascular disease. Although its pathogenesis is not yet fully understood, the disruption of the renin‑angiotensin system (RAS), consisting of the systemic and brain RAS, has been recognized as one of the primary reasons for several types of hypertension. Therefore, acquiring sound knowledge of the basic science of RAS and the underlying mechanisms of the signaling pathways associated with RAS may facilitate the discovery of novel therapeutic targets with which to promote the management of patients with cardiovascular and kidney disease. find more In total, 4 types of angiotensin II receptors have been identified (AT1R‑AT4R), of which AT1R plays the most important role in vasoconstriction and has been most extensively studied. It has been found in several regions of the brain, and its distribution is highly associated with that of angiotensin‑like immunoreactivity in nerve terminals. Theghlight the prevalence, functions, interactions and modulation means of central AT‑1R in an effort to assist in the treatment of several pathological conditions. The identification of angiotensin‑derived peptides and the development of AT‑2R agonists may provide a wider perspective on RAS, as well as novel therapeutic strategies.Previous studies have confirmed that 50 µmol/l pinacidil postconditioning (PPC) activates the nuclear factor‑E2 related factor 2 (Nrf2)‑antioxidant responsive element (ARE) pathway, which protects the myocardium from ischemia‑reperfusion (IR) injury; however, whether this is associated with reactive oxygen species (ROS) generation remains unclear. In the present study, a Langendorff rat model of isolated myocardial IR was established to investigate the mechanism of PPC at different concentrations, as well as the association between the rat myocardial Nrf2‑ARE signaling pathway and ROS. A total of 48 rats were randomly divided into the following six groups (n=8 per group) i) Normal; ii) IR iii) 10 µmol/l PPC (P10); iv) 30 µmol/l PPC (P30); v) 50 µmol/l PPC (P50); and vi) N‑(2‑mercaptopropionyl)‑glycine (MPG; a ROS scavenger) + 50 µmol/l pinacidil (P50 + MPG). At the end of reperfusion (T3), compared with the IR group, the P10, P30 and P50 groups exhibited improved cardiac function, such as left ventricular dev cardiac function of the P50 + MPG group was significantly decreased, ultrastructure of cardiomyocytes was significantly impaired and the relative expression levels of genes and proteins in the Nrf2‑ARE pathway were decreased. The aforementioned results confirmed that different PPC concentrations promoted early generation of ROS and activated the Nrf2‑ARE signaling pathway following reperfusion, regulated expression levels of downstream antioxidant proteins and alleviated myocardial IR injury in rats. Treatment with 50 mmol/l pinacidil resulted in the best myocardial protection.Prednisolone is an anti‑inflammatory drug used to treat a number of conditions, including liver disease and cancer. Numerous studies have demonstrated that glucocorticoids such as prednisolone modified by ionizing radiation can promote anticancer activity in cancer cells. To the best of our knowledge, however, the effect of ionizing radiation on prednisolone structure and cancer cells has not yet been identified. The present study created a novel prednisolone derivative using γ‑irradiation, and its anticancer properties were investigated in liver cancer cells. The present study confirmed the structure of the new prednisolone derivative using liquid chromatogram‑mass spectrometry. MTT assays determined the cytotoxic effects of γ‑irradiated (IR)‑prednisolone in liver cancer cells. Flow cytometry analysis evaluated apoptosis, mitochondrial membrane potential and cell cycle distribution. Western blotting was used to analyze the proteins associated with apoptosis. The chromatogram profile revealed that IR‑prednisolone produced a number of peaks compared with the single peak of the original prednisolone. In contrast to prednisolone, the MTT results showed that IR‑prednisolone significantly prevented the growth of liver cancer cells. IR‑prednisolone promoted apoptosis and arrested the cell cycle at the G0/G1 stage in Huh7 cells. IR‑prednisolone also altered the mitochondrial membrane potential and activated caspase‑associated proteins, which activated the intrinsic apoptotic signaling pathway. In conclusion, IR‑prednisolone promoted anticancer effects in liver cancer cells via apoptosis activation. The present study demonstrated that IR‑prednisolone may be a potential anticancer agent against liver cancer, although specific molecules have yet to be identified.Endometriosis (EM) is a common gynecological disease, and its pathological process is accompanied by the migration and proliferation of uterine cells. Berberine (BBR) has been shown to exhibit antitumor activity; however, the effects of BBR on EM have seldom been reported to date. The expression of microRNA (miR)‑429 is upregulated in EM and miR‑429 can be used as a target for drug regulation of cancer cells. Whether BBR plays a regulatory role in EM by targeting miR‑429 has not been reported. Thus, the aim of the present study was to determine the effects of BBR on EM cells. The survival rate of immortalized human endometrial stromal cells (HESCs) was determined using a Cell Counting Kit‑8 assay. A colony formation assay was used to detect the rate of cell proliferation. The expression levels of proliferation‑related proteins, including proliferation marker protein Ki‑67 (Ki‑67) and proliferating cell nuclear antigen (PCNA), were detected by reverse transcription‑quantitative PCR (RT‑qPCR) and western blottiing the expression of miR‑429.Kidney cancer is a malignant tumor of the urinary system. Although the 5‑year survival rate of patients with kidney cancer has increased by ~30% in recent years due to the early detection of low‑grade tumors using more accurate diagnostic methods, the global incidence of kidney cancer continues to increase every year. Therefore, identification of novel and efficient candidate genes for predicting the prognosis of patients with kidney cancer is important. The present study aimed to investigate the role of SEC61 translocon subunit‑γ (SEC61G) in kidney cancer. The Cancer Genome Atlas database was screened to obtain the expression profile of SEC61G and identify its association with kidney cancer prognosis. Furthermore, the in vitro effect of SEC61G knockdown on kidney cancer cell proliferation, migration, invasion and apoptosis was investigated using a Cell Counting Kit‑8 assay, wound healing assay, Transwell assay and flow cytometry. The results demonstrated that compared with healthy tissues, SEC61G was upregulated in human kidney tumor tissues, which was associated with poor prognosis.
