Pembrolizumab in endometrial cancers: Where we remain today.
Acupuncture inhibited neuronal damage, activation of microglia, and inflammatory cytokines. The expressions of α7nAChR, together with its downstream JAK2/STAT3 pathways were up regulated by acupuncture. PNU282987 mimicked the anti-inflammatory and neuroprotective effects as well as the cognitive improvements of acupuncture. Meanwhile, the benefit effects of acupuncture above were blocked by α-BGT.

It was demonstrated that acupuncture promoted cognitive function and afforded neuroprotective effects against inflammation via activation of α7nAChR and its downstream JAK2-STAT3 pathway in CCH rats. It provides a new insight for acupuncture as an anti-inflammatory intervention for cognitive impairment.

Polycystic ovary syndrome (PCOS), the rifest endocrine disorder in women, is involved in disrupting many metabolic processes. However, the impact of PCOS on cognitive deficits is still uncertain. Recently, Notch signaling pathway was identified as a key modifier in regulating the pathological process in the ovary and various neurodegenerative disorders. Liraglutide has favourable neuroprotective effects that may protect against the possible cognitive dysfunction in PCOS.

PCOS was induced in rats by administrating Letrozole orally for 21 successive days. Then, Liraglutide (LIR) was administered intraperitoneally for 30days. Memory was examined using Y-maze, novel object recognition (NOR), and Morris water maze (MWM) tests. Western blotting, enzyme immunoassay, and quantitative real-time PCR were used to examine Notch signaling downstream targets, as well as assessing the expression of the components of various pathways cross talked with Notch signaling in memory impairment. Furthermore, histopathological etia.Reserpine is a natural indole alkaloid isolated from Rauwolfia serpentina and has potent antioxidant, antimicrobial, and anti-mutagenic properties. Accordingly, this study aimed to investigate the effect of reserpine on DNA repair, cell proliferation, invasion and apoptosis in 7,12-dimethylbenz[a]anthracene(DMBA)-induced hamster buccal pouch (HBP) carcinogenesis. Transforming growth factor-β (TGF-β) was found to induce Smad2, 3 and 4 phosphorylation triggering Smad3/Snail mediated DNA repair proteins and Smad2/4 nuclear translocation. In contrast, reserpine inhibits TGF-β dependent Smad2/3/4 phosphorylation, thereby blockage Smad3/Snail activation and Smad2/4 nuclear translocation. Interruption of these oncogenic signaling pathways leads to downregulating ERCC1, XPF, Ku70, DNA-PKcs, PCNA, cyclin D1, HIF-1α, IL-6, Mcl-1 and stimulates Bax, cytochrome C, Apaf-1, caspase-9, caspase-3 and PARP protein expressions. This study provides therapeutic potential of reserpine in inhibiting DNA repair, cell proliferation, and invasion while simultaneously inducing apoptosis via modulation TGF-β signals.
Gypenoside (GP) is the major bioactive constituent of G. BMS-986278 purchase pentaphyllum, a traditional Chinese medicine. It has been reported that GP can affect autophagy and lipid metabolism in cultured cells. We hypothesize that GP can inhibit foam cell formation in cultured macrophages through autophagy modulation.

THP1 cells were cultured and treated with oxidized low-density lipoprotein (ox-LDL), followed by GP treatment at different concentrations. The autophagy flux was evaluated using western blot and confocal microscope analyses. The ox-LDL uptake and foam cell formation abilities were measured.

We found that ox-LDL impaired the autophagy flux in the cultured macrophages, indicated by a significant reduction of LC3-II and autophagosome puncta quantification, as well as an accumulation of p62 proteins. GP treatment, however, dose-dependently restored the autophagy flux impaired by ox-LDL and reduced the ox-LDL uptake and foam cell transformation from THP1 cells, which can be alleviated, or exacerbated, by modulation of autophagy status using autophagy enhancer or inhibitor. Coimmunoprecipitation assays showed that GP up-regulated Srit1 and FOXO1 expression and enhanced their direct interaction, and thus contributed to the regulation of autophagy.

GP inhibits ox-LDL uptake and foam cell formation through enhancing Sirt1-FOXO1 mediated autophagy flux restoration, suggesting this compound has therapeutic potential for atherosclerosis.

Diabetic nephropathy (DN) is the most frequent complication of diabetes and causes millions of deaths each year. Finding novel therapy to DN is urgent, which requires a good understanding of the pathogenesis. Aims are to investigate the molecular mechanisms of DN by focusing on ANRIL/miR-497/TXNIP axis.

Kidney tissues were collected from diagnosed DN patients. High glucose (HG) treatment of human renal tubular epithelial cell cells (HK-2) was used as the cell model of DN. qRT-PCR and Western blotting were performed to measure levels of ANRIL, miR-497, TXNIP, IL-1β, IL-18, caspase-1, and NLRP3. LDH leakage and cell viability were determined with commercial LDH activity kit and MTT assay. ELISA was employed to examine secreted IL-1β and IL-18 levels. Flow cytometry was used to examine caspase-1 activity. Dual luciferase assay was performed to validate interactions of ANRIL/miR-497 and miR-497/TXNIP.

ANRIL and TXNIP were elevated in DN kidney tissues and HG-treated HK-2 cells while miR-497 was reduced. ANRIL bound miR-497 while miR-497 directly targeted TXNIP. Knockdown of ANRIL suppressed HG-induced LDH leakage, TXNIP/NLRP3/caspase-1 activation, and increases of IL-1β and IL-18 secreted levels. miR-497 knockdown or TXNIP overexpression reversed the effects of ANRIL knockdown on LDH leakage and pyroptosis-related signaling. miR-497 mimics inhibited caspase-1-dependent pyroptosis while co-overexpression of TXNIP blocked its effects in HG-treated HK-2 cells.

ANRIL promotes pyroptosis and kidney injury in DN via acting as miR-497 sponge to disinhibit TXNIP expression. These results shed light on the mechanisms of DN and provide targets for therapy development.
