Moreover, circ_400068 regulated the proliferation of HK‑2 cells by targeting the miR‑210‑5p/SOCS1 axis, as the effects on cell proliferation caused by treatment using exosomes isolated from the culture media of RCC cells were abolished by miR‑210‑5p mimics. It was found that enhanced cell proliferation induced by miR‑210‑5p inhibitors was attenuated by the knockdown of SOCS1, while the influences triggered by miR‑210‑5p mimics were reversed by SOCS1 overexpression. Collectively, the present findings provided a novel insight into the crucial regulatory functions of circ_400068 in RCC, and the circ_400068/miR‑210‑5p/SOCS1 axis could be a candidate therapeutic target for the treatment of patients with RCC.Recent studies have demonstrated that nobiletin (NOB) displays anti‑oxidative and anti‑apoptotic efficacies against multiple pathological insults. However, the potential effects of NOB on the injury caused by ischemia and reperfusion (I/R) in the kidney remain undetermined. In the present study, I/R injury was elicited by right kidney removal and left renal pedicel clamping for 45 min, followed by reperfusion for 24 h. NOB was added at the start of reperfusion. Histological examination, detection of biomarkers in plasma, and measurement of apoptosis induced by endoplasmic reticulum stress (ERS) were used to evaluate renal injury. Additionally, the PI3K/AKT inhibitor LY294002 was also used in mechanistic experiments. NOB pre‑treatment significantly reduced renal damage caused by I/R injury, as indicated by decreased serum levels of creatine, blood urea nitrogen and tubular injury scores. Furthermore, NOB inhibited elevated ERS‑associated apoptosis, as evidenced by reduced apoptotic rates and ERS‑related signaling molecules (such as, C/EBP homologous protein, caspase‑12 and glu
