Analysis of the gut microflora revealed significant changes in their composition. Several important micro-organisms that were deficient in the SHRs were found up-regulated by the treatments, including Turicibacter and Romboutsia which are involved in the short-chain fatty acid production.

Exercise training and VC intake individually can modify the gut microflora composition and improve the inflammatory state in both PVN and intestine, which contribute to their anti-hypertensive function. Combination of the two treatments enhanced their effects and worth to be considered as a non-medical aid for the hypertensive patients.

Cell proliferation was examined by MTT, cell cycle and apoptosis were detected by flow cytometry. The overgrowth pterygium tissues were characterized by H&E staining and IHC compared with normal tissues. Differential mRNA expression with MG-132 treatment was determined by RNA sequencing and analyzed by GO and KEGG pathways. The expression levels of Nrf2, MCPIP1, CDKN1B and XBP1, four genes closely associated with pterygium, were detected by RT-qPCR and western blotting. MG-132 dose-dependently inhibited the growth of HPFs, induced G2/M phase arrest of cell cycle at a certain dose, and also caused cell apoptosis, with the levels of cleaved caspase3, cleaved PARP, Bax and p21 increased. Ki-67 and Bcl-2 were highly expressed while Bax was decreased in pterygium tissues. Total 7199 differentially expressed genes (DEGs) were identified, including HSPA family most significantly increased, and AL590428.1, AL122125.1 and lincRNAs such as FGF14-AS2 decreased. The up-regulated DEGs were mainly enriched in RNA degradation pathway, while down-regulated DEGs were related to the regulation of cell cycle. The expressions of Nrf2 and MCPIP1 were significantly increased, while XBP1 and CDKN1B were decreased. In conclusion, MG-132 inhibited the proliferation and induced apoptosis of HPFs in vitro with 7199 DEGs participated in, which may provide a useful reference for the exploitation of MG-132 in treating pterygium.

Accumulating evidence has reported the role of microRNA (miR) on ischemic brain injury. We aim to investigate the mechanism of miR-376b-5p/Sex-determining region Y-box 7 (SOX7)/Wnt/β-catenin axis in mice with ischemic brain injury.

Transient middle cerebral artery occlusion (tMCAO) model was established by suture method. Expression levels of miR-376b-5p, SOX7, and Wnt/β-catenin pathway-related proteins (Wnt3a and β-catenin) in brain tissues of tMCAO mice were determined by RT-qPCR and western blot analysis. The target relationship between miR-376b-5p and SOX7 was tested by bioinformatics analysis and luciferase activity assay. The neurological scores of mice were recorded and their behaviors were observed. Moreover, the brain damage, oxidative stress indices, hemoglobin (Hb) content, content of brain water, infarct area, TUNEL positive cells, blood-brain barrier permeability and the number of intact neurons in the ischemic-side brain tissues of tMCAO mice were detected via upregulated miR-376b-5p or downregulated SOX7.

In mice with ischemic brain injury, miR-376b-5p targeted and downregulated SOX7 in brain tissues, thus activating the Wnt/β-catenin pathway. The tMCAO mice showed higher neurological scores, severe brain damage, decreased number of neurons, as well as elevated blood-brain barrier permeability, Hb content, cerebral edema and infarct area. These symptoms could be alleviated by miR-376b-5p elevation or SOX7 inhibition. SOX7 overexpression reversed the effects of miR-376b-5p elevation on tMCAO mice.

Our study suggests that miR-376b-5p could improve the blood-brain barrier permeability, relieve brain edema and decrease infarct area, thus improve ischemic brain injury via the inhibition of SOX7 and activation of Wnt/β-catenin pathway.

Polo-like kinase 2 (PLK2) belongs to a family of serine/threonine kinases, and it is involved in tumorigenesis. The present study aimed to explore the potential clinical significance of PLK2 in the development of gliomas.

Immunohistochemistry (IHC) was performed to detect the expression of PLK2 in glioma tissues. Cell proliferation and apoptosis were determined by Cell Counting Kit 8 (CCK8) and flow cytometry analysis, respectively.

PLK2 expression gradually increased with the degree of glioma malignancy. High PLK2 expression was associated with a poor prognosis in glioma. Short hairpin RNAs targeting PLK2 (shPLK2) inhibited the viability and induced apoptosis of glioma cells, both in vitro and in vivo. Ring finger protein 180 (RNF180), an E3 ubiquitin ligase, interacted with PLK2 and induced the ubiquitination of PLK2. Overexpression of PLK2 in glioma cells significantly inhibited RNF180 upregulation-induced cell apoptosis. The expression level of RNF180 gradually decreased with the degree of glioma malignancy.

Knocking down of PLK2 may suppress the glioma development through cancer cell proliferation inhibition and cell apoptosis promotion. Furthermore, RNF180 may mediate the ubiquitination of PLK2. The present findings may help improve the clinical management of glioma in the future.
