ABSTRACT

The inositol polyphosphate-5-phosphatase ( INPP5E) gene encodes INPP5E, which is widely distributed in various tissues of humans and mice like the heart, brain and testis.It affects the phosphoinositide metabolic pathway by regulating the intracellular phosphatidylinositol triphosphate content, thus participating in intracellular signal transduction, cell proliferation and differentiation, cell polarity and other processes.The INPP5E gene plays a pivotal role in primary ciliogenesis and is closely related to childhood ciliary diseases.Therefore, this article review the research progress of the INPP5E gene in primary cilium-related pediatric diseases.Combined with laboratory findings, this review aims to provide new ideas for the regulation of the INPP5E gene in primary cilia and the prevention and treatment of pediatric ciliopathies.

ABSTRACT

Objective:To evaluate the role of silencing regulatory protein (SIRT1) and its associated microRNAs (miRNAs) in dexmedetomidine-induced attenuation of renal damage in diabetic mice.Methods:SPF grade C57 male mice, aged 8 weeks, in which diabetes mellitus model was developed by intraperitoneal injection of 1% streptozotocin, were used.Thirty mice in which the model was successfully developed were divided into 5 groups ( n=6 each) using the random number table method: diabetes mellitus group (D group), diabetes mellitus + dexmedetomidine group (DD group), diabetes mellitus + dexmedetomidine + EX527 group (DDE group), diabetes mellitus + dexmedetomidine + miR-34a-3p-agomir group (DDH group), and diabetes mellitus + dexmedetomidine + miR-34a-3p-agomirNC group (DDC group). Six normal mice were selected as control group (C group). Dexmedetomidine 40 μg/kg was intraperitoneally injected once every 2 h, 3 times in total in DD, DDE, DDH and DDC groups.miR-34a-3p-agomir and miR-34a-3p-agomirNC 2.5 mmol were intraperitoneally injected via the tail vein at 72 h before dexmedetomidine administration once every 3 days, 2 times in total in DDH and DDC groups, respectively.SIRT1 inhibitor EX527 10 mg/kg was intraperitoneally injected at 1 h before dexmedetomidine administration in group DDE.At 24 h after the end of administration, serum concentrations of IL-6, IL-18, Cr and BUN, contents of nitric oxide (NO) and total antioxidant capacity (T-AOC), ROS activity, and expression of SIRT1, FoxO3a and P53 protein and mRNA, and expression of miR-217, miR-138 and miR-34a in renal tissues were determined. Results:Compared with group C, the serum IL-6, IL-18, Cr and BUN concentrations, contents of T-AOC and NO, and ROS activity were significantly increased, the expression of P53 protein and mRNA, miR-34a, miR-217 and miR-138 was up-regulated, and the expression of SIRT1 and FoxO3a protein and mRNA was down-regulated in group D ( P<0.05). Compared with group D, serum IL-6, IL-18, Cr and BUN concentrations, ROS activity and NO content were significantly decreased, T-AOC content was increased, the expression of SIRT1 and FoxO3a protein and mRNA was up-regulated, and the expression of miR-34a was down-regulated in group DD ( P<0.05). Compared with group DD, the serum IL-6, IL-18, Cr and BUN concentrations, NO content and ROS activity were significantly increased, T-AOC content was decreased, and the expression of SIRT1 and FoxO3a protein and mRNA was down-regulated in group DDE and group DDH ( P<0.05), no significant change was found in the expression of P53 protein and mRNA, miR-217, miR-34a and miR-138 in group DDE ( P>0.05), and the expression of P53 protein and mRNA and miR-34a was significantly up-regulated in group DDH ( P<0.05). Conclusions:The mechanism by which dexmedetomidine attenuates renal injury may be related to down-regulation of miR-34a expression, which further up-regulates SIRT1/FoxO3 expression and decreases oxidative stress in diabetic mice.
