a triantennary trisialylated glycan, and 3086.39, a lewis type triantennary glycan) combined with CA125 performed better descrimination of these two groups with AUC of 0.88. These altered glycans might serve as biomarkers to reflect patients' drug sensitivity and to guide clinical treatment. V.AIMS RING1 and YY1-binding protein (RYBP) is an epigenetic regulator and plays crucial roles in embryonic development. The anti-tumor effect of RYBP has been reported in several cancers recently, but the role of RYBP in esophageal squamous cell carcinoma (ESCC) has not been fully elucidated. The present study aimed to investigate the biological function and the underlying molecular mechanisms of RYBP in ESCC. MATERIALS AND METHODS We detected the expression of RYBP in ESCC tissue microarrays (TMA) by immunohistochemistry. Cell proliferation was assessed by CCK8 and colony formation assays. Cell cycle was analyzed by flow cytometry. Gene expression was determined by transcriptome arrays, quantitative real-time PCR (qRT-PCR) and Western blot. Four-week-old male nude mice were used to evaluate the effect of RYBP in ESCC growth. KEY FINDINGS We found that RYBP was downregulated in ESCC compared with adjacent normal tissues. A high level of RYBP expression predicted a better outcome of ESCC patients. Furthermore, overexpression of RYBP inhibited ESCC growth both in vitro and in vivo. Transcriptome arrays and functional studies showed that RYBP decreased the expression of genes related to cell cycles, especially CDC6 and CDC45, which were essential to initiate the DNA replication and G1-S transition. https://www.selleckchem.com/products/pf-06952229.html SIGNIFICANCE Taken together, our study suggests that RYBP suppresses ESCC proliferation by downregulating CDC6 and CDC45, thus inhibiting the G1-S transition. Although extensive research progress has been made in breast cancer in recent years, yet the morbidity and mortality rates of breast cancer are rising, making it the major disease that endangers women's health. Energy metabolism reprogramming is featured by a state termed "aerobic glycolysis" or the Warburg effect that glycolysis is preferred even under aerobic conditions in neoplastic diseases. Widely acknowledged as an emerging hallmark in cancers, this metabolic switch shows a sophisticated role in the pathogenesis of breast cancer. The regulating effect of non-coding RNAs (ncRNAs) composed of microRNAs, long non-coding RNAs and circular RNAs is closely related to the glycolysis in breast cancer. Therefore, understand the mechanisms of ncRNAs of aerobic glycolysis in breast cancer may provide new strategy for the disease. AIMS Cisplatin (CDDP) is an effective antineoplastic agent, however, its serious nephrotoxicity limits therapeutic use. Human growth hormone (hGH) has proved antioxidant and anti-inflammatory activities. The present study aimed to investigate the nephroprotective effects of hGH against CDDP-induced nephrotoxicity and the mechanisms underlying this nephroprotection. MAIN METHODS Male albino rats injected with CDDP (7 mg/kg) and nephrotoxicity indices, oxidative stress and inflammatory biomarkers (high mobility group box protein-1 (HMGB-1), soluble epoxide hydrolase (sEH), and nuclear factor-kappa B (NF-κB)) were assessed. Also, insulin-like growth factor-1 (IGF-1) and Nuclear factor-erythroid-2 (Nrf2)/heme oxygenase-1 (HO-1) pathway were assessed. KEY FINDINGS hGH (1 mg/kg) improved kidney function and antioxidant systems and showed intact renal tubular epithelium. Cisplatin upregulated the HMGB-1/NF-κB and downregulated Nrf2/HO-1 pathways which were reversed by hGH and aligned with increased renal IGF-1 expression. Also, IGF-1/sEH crosstalk might be involved in hGH nephroprotection. Moreover, hGH downregulated HSP70 and caspase-3 expressions. SIGNIFICANCE these results concluded that hGH can attenuate the inflammation and oxidative stress attained by CDDP probably through inhibition of Nrf2/HO-1 pathway. We also suggested that Keap1/Nrf2-mediated upregulation of the antioxidant HO-1 might inhibit HMGB-1/NF-κB signaling and thus provide the principal protection mechanism offered by hGH against CDDP-induced kidney injury. Chronic intermittent hypoxia (CIH) is a consequence of obstructive sleep apnea (OSA), which increases reactive oxygen species (ROS) generation, resulting in oxidative damage and neurocognitive impairment. This study was designed to determine whether abnormal iron metabolism occurs in the brain under conditions of CIH and whether Huperzine A (HuA) could improve abnormal iron metabolism and neurological damage. The mouse model of CIH was established by reducing the percentage of inspired O2 (FiO2) from 21% to 9% 20 times/h for 8 h/day, and Huperzine A (HuA, 0.1 mg/kg, i.p.) was administered during CIH exposure for 21 days. HuA significantly improved cognitive impairment and neuronal damage in the hippocampus of CIH mice via increasing the ratio of Bcl-2/Bax and inhibiting caspase-3 cleavage. HuA considerably decreased ROS levels by downregulating the high levels of NADPH oxidase (NOX 2, NOX 4) mediated by CIH. There was an overload of iron, which was characterized by high levels of ferritin (FTL and FTH) and transferrin receptor 1 (TfR1) and low levels of ferroportin 1 (FPN1) in the hippocampus of CIH mice. Decreased levels of TfR1 and FTL proteins observed in HuA treated CIH group, could reduce iron overload in hippocampus. HuA increased PSD 95 protein expression, CREB activation and BDNF protein expression to protect against synaptic plasticity impairment induced by CIH. HuA acts as an effective iron chelator to attenuate apoptosis, oxidative stress and synaptic plasticity mediated by CIH. BACKGROUND Hip fractures are associated with mortality, disability, and loss of independence in older adults. While several risk factors associated with poor outcomes following a hip fracture have been identified, the effect of frailty status prior to hip fracture is not well established. AIM To examine the associations of frailty with mortality, change in activities of daily living (ADL) limitations, and transition to permanent residential aged care in older people following a hip fracture. METHODS A retrospective cohort study was conducted on people aged 65 years and older with a surgically treated hip fracture between 2003 and 2015. Frailty was estimated using a cumulative deficit-based frailty index and categorized into quartiles. Cox multivariable regression, logistic regression, and Fine-Gray multivariable regression models estimated associations of frailty with mortality, ADL limitations, and entry into permanent residential aged care, respectively. Hazard ratios (HR), odds ratios (OR), subdistribution hazard ratios (SHR), and 95% confidence intervals (95%CI) are reported.
