Neuroinflammation plays important roles in the pathogenesis and progression of altered neurodevelopment, sensorineural hearing loss, and certain neurodegenerative diseases. Hyperoside (quercetin-3-O-β-D-galactoside) is an active compound isolated from Hypericum plants. In this study, we investigate the protective effect of hyperoside on neuroinflammation and its possible molecular mechanism. Lipopolysaccharide (LPS) and hyperoside were used to treat HT22 cells. The cell viability was measured by MTT assay. The cell apoptosis rate was measured by flow cytometry assay. The mRNA expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) were determined by quantitative reverse transcription polymerase chain reaction. The levels of oxidative stress indices superoxide dismutase (SOD), reactive oxygen species (ROS), catalase (CAT), glutathione (GSH), and malondialdehyde (MDA) were measured by the kits. The expression of neurotrophic factor and the relationship among hyperoside, silent mating type information regulation 2 homolog-1 (SIRT1) and Wnt/β-catenin, and sonic hedgehog was examined by western blotting. In the LPS-induced HT22 cells, hyperoside promotes cell survival; alleviates the level of IL-1β, IL-6, IL-8, TNF-α, ROS, MDA, Bax, and caspase-3; and increases the expression of CAT, SOD, GSH, Bcl-2, BDNF, TrkB, and NGF. In addition, hyperoside upregulated the expression of SIRT1. Further mechanistic investigation showed that hyperoside alleviated LPS-induced inflammation, oxidative stress, and apoptosis by upregulating SIRT1 to activate Wnt/β-catenin and sonic hedgehog pathways. Taken together, our data suggested that hyperoside acts as a protector in neuroinflammation.
Gliomas are the most common and aggressive type of primary adult brain tumors. Although GGNBP2 has previously been considered to be a tumor suppressor gene, little is known about the association between GGNBP2 and glioma. In this study, we clearly demonstrated that GGNBP2 was downexpressed in glioma tissues, and its downexpression is related to the pathological grade and overall survival of patients with gliomas. Overexpression of GGNBP2 suppressed the proliferation, migration, and invasion of glioma cells. Mechanistically, we demonstrated that the PI3K/Akt and Wnt/β-catenin signaling pathways were suppressed by GGNBP2 overexpression. In contrast, knockdown of GGNBP2 has precisely the opposite effect. Collectively, these data indicate that GGNBP2 shows tumor suppressive activity in human glioma cells and may stand out as a potential therapeutic target for glioma.
The objective of this study was to investigate the effect of ATP7B antisense oligodeoxynucleotides (ASODNs) on regulating the sensitivity to cisplatin in ovarian carcinoma cell line SKOV3ip1. The ATP7B ASODNs and the corresponding sense oligodeoxynucleotide (SODN) as control were transfected into SKOV3ip1 cells by lipofectamine-2000. The changes of ATP7B were detected by reverse transcription-polymerase chain reaction, flow cytometry, and Western blotting. The survival rate of the SKOV3ip1 cells was assessed by MTT assay. Compared with nontransfected cell, the transfer of ASODN/lipofectin (LF) into SKOV3ip1 cells resulted in (1) 73.70% and 48.30% reduction of ATP7B in messenger RNA and protein, respectively, (2) an obviously decreased intracellular fluorescence intensity from 79.42 to 50.87 (P < 0.01), and (3) a decreased IC(50) value for cisplatin from 126.63 to 80.90 micromol/L (P < 0.01), while no significant changes were detected for groups treated with SODN/LF and LF only. ASODN transfection can inhibit the expression of ATP7B and increase the cisplatin sensitivity in SKOV3ip1 cells.
Objective: To investigate the clinical efficacy and safety of interventional embolization in the treatment of anterior circulation aneurysms. Methods: Eighty patients with anterior circulation aneurysms admitted to People’s Hospital of Leshan from June 2019 to December 2021 were retrospectively analyzed. According to the different surgical methods, they were divided into two groups: the observation group and the control group. Patients in the observation group were given interventional embolization, while those in the control group were given craniotomy clipping. The surgical efficacy, postoperative neurological function and quality of life, surgical prognosis and surgical complications of the two groups were compared. Results: The intraoperative blood loss and hospitalization time in the observation group were lower than those in the control group (p<0.05). The scores of the Hunt-Hess and modified Rankin scale in the observation group were significantly lower than those in the control group three months after surgery (p<0.05). The good prognosis rate of the observation group was higher than that of the control group (p<0.05). Moreover, the complication rate of the observation group was 12.50%, which was significantly lower than 32.50% in the control group (p<0.05). Conclusion: Interventional embolization shows the advantages of minimally invasive procedures such as shorter operative times and shorter hospital stays. It has better clinical safety because it can significantly improve the neurological function and quality of life of patients, improve the prognosis of patients, and reduce the incidence of complications. doi: https://doi.org/10.12669/pjms.39.5.7092 How to cite this: Lei B, You G, Wan X, Wu H, Zheng N.
