Background. Contrast-induced acute kidney injury (CI-AKI) is one of the main causes of iatrogenic acute kidney injury (AKI); however, therapeutic strategies for AKI remain limited. This study aims to explore the effect of relaxin (RLX) on contrast-induced HK-2 apoptosis and its underlying mechanisms.Methods. Renal tubular epithelial cells (HK-2) were incubated either with or without ioversol, human H2 relaxin, and LY294002 (the inhibitor of the PI3K/Akt signal pathway). Cell viability was evaluated with a CCK-8 assay. Apoptotic morphologic alterations were observed using the Hoechst 33342 staining method. Apoptosis was detected with Annexin V staining. Western blot analysis was employed to measure the expression of pAkt (S473), Akt, cleaved caspase-3, Bcl-2, Bax, and actin proteins.Results. Ioversol reduced the viability of HK-2 cells. Western blotting results revealed decreased expression of phosphorylated Akt in cells treated with ioversol. The activities of caspase-3 and Bax protein increased, while the expression of Bcl-2 protein decreased. As a result, the Bax/Bcl-2 ratio increased after treatment with ioversol. These effects were reversed when HK-2 cells were cotreated with RLX. However, with preadministration of PI3K/Akt pathway inhibitor LY294002, the effect of RLX was blocked.Conclusion. Our study demonstrates that relaxin attenuates ioversol induced cell apoptosis via activation of the PI3K/Akt signaling pathway, suggesting that RLX might play a protective role in the treatment of CI-AKI.

Glioma is a highly fatal malignancy with aggressive proliferation, migration, and invasion metastasis due to aberrant genetic regulation. This work aimed to determine the function of transmembrane protein 60 (TMEM60) during glioma development. The level of TMEM60 in glioma tissues and normal tissues and its correlation with glioma prognosis were checked in The Cancer Genome Atlas (TCGA) database. The levels of TMEM60 in glioma cell lines and normal astrocytes were determined by quantitative real-time PCR and western blotting assay. TMEM60 knockdown and overexpression were conducted, followed by detection of cell viability, migration, invasion, and apoptosis. CCK-8 and colony formation assay were adopted to detect cell viability proliferation. Transwell assay was performed to measure cell migration and invasion. Cell apoptosis was evaluated by flow cytometry. The alternation of key proteins in the PI3K/Akt signaling pathway was measured by western blotting. TMEM60 expression was significantly higher in glioma tissues than that in the healthy control and was correlated with poor overall survival of patients. The protein and mRNA levels of TMEM60 were both elevated in glioma cell lines in comparison with the normal cell lines. Elevated level of TMEM60 led to enhanced proliferation, migration, and invasion and suppressed cell apoptosis. TMEM60 promoted the activation of PI3K/Akt signaling. Our data suggested that TMEM60 plays an oncogenic role in glioma progression via activating the PI3K/Akt signaling pathway.

Abstract Background Araloside C (AsC), a natural saponin isolated from Aralia elata, has a wide range of anti-inflammatory properties and has been found in recent years to have heart-protective effects. Present study aimed to determine the effects of AsC on myocardial cell apoptosis through regulating PI3K/AKt. Methods and Results Statistical analyses were performed using GraphPadPrism7.0 software. The differences between two groups and multiple groups were analyzed using t-test and one-way ANOVA, respectively. In vivo results showed that AsC administration could improve cardiac functions and apoptotic rate in HF model through PI3K/AKt signaling pathway, including increasing left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS), and decreasing left ventricular end systolic diameter (LVESD) and left ventricular end diastolic diameter (LVEDD) in detection of myocardial function, inhibiting LDH, CK, CK-MB, CK and HBDH in biochemical index level assessment, inhibiting BNP, ANG II, IL-1b, IL-4, IL-6 and TNF-a in immunological index level. ASC regulates the expression of key apoptotic molecules, including increasing the expression of Bcl-2 and Bax. ASC also regulates phosphorylation of p-PI3K and p-Akt.Conclusion This study suggested for the first time that AsC could partially regulate the PI3K/AKt signaling pathway to prevent myocardial cell apoptosis. This study provided a basis for further research on effective substances in the treatment of HF.
