DNA topoisomerase II alpha (TOP2A) reportedly plays a crucial role in several cancers, however, the precise regulatory role of TOP2A in metastatic characteristics of glioma is still poorly understood. Herein, we sought to elucidate the mechanisms by which TOP2A affects the metastatic phenotypes of glioma. We observed that a high level of TOP2A expression was dramatically linked with inferior survival in glioma patients while silencing of TOP2A impaired glioma cell proliferation and aggressiveness. TOP2A was...

In the present study, we aimed to investigate the role of long non-coding RNA terminal differentiation-induced non-coding RNA (TINCR) in cisplatin (DDP) resistance of choroidal melanoma (CM) and the potential molecular mechanisms. CM and non-CM tissues were collected from 60 CM patients. DDP-resistant CM cells were obtained by selection with linearly increased DDP treatment. The expression levels of TINCR, microR-19b-3p (miR-19b-3p), and extracellular signal-regulated kinase 2 (ERK-2) were detected by quantitative real-time PCR. Cholecystokinin octapeptide...

Macroautophagy/autophagy is a conserved cellular process associated with tumorigenesis and aggressiveness, while mechanisms regulating expression of autophagic machinery genes in cancers still remain elusive. Herein, we identified E2F4 (E2F transcription factor 4) as a novel transcriptional activator of cytoprotective autophagy crucial for zinc homeostasis in cancer cells. Gain- and loss-of-function studies showed that E2F4 promoted autophagy in a cell cycle-dependent manner, resulting in facilitated degradation of MT (metallothionein) proteins, elevated distribution of Zn2+ within autophagosomes,...

The anterior cingulate cortex (ACC) is a core brain region processing pain emotion. In this study, we performed RNA sequencing analysis to reveal transcriptomic profiles of the ACC in a rat chronic constriction injury (CCI) model. A total of 1628 differentially expressed genes (DEGs) were identified by comparing sham-operated rats with rats of 12 hours, 1, 3, 7, and 14 days after surgery, respectively. Although these inflammatory-related DEGs were generally increased after CCI, different kinetics...

This study aims to determine the effect of exogenous hydrogen sulfide (H2S) under high glucose (HG)-induced injury in endothelial progenitor cells (EPCs), and to explore the possible underlying mechanisms. Mononuclear cells were isolated from the peripheral blood of healthy volunteers by density-gradient centrifugation and identified as late EPCs by immunofluorescence and flow cytometry. EPCs were treated with high concentrations of glucose, H2S, Baf-A1, 3-MA or rapamycin. Cell proliferation, cell migration and tube formation were measured...

Docosahexaenoic acid (DHA) has numerous functions in adjusting the organic health and pragmatic value in medicine and food field. In this study, we compared glycerol and glucose as the only carbon source for DHA production by Aurantiochytrium. When the glycerol concentration was 120 g/L, the maximum DHA yield was 11.08 g/L, and the DHA yield increased significantly, reaching 47.67% of the total lipid content. When the cells grew in glucose, the DHA proportion was 37.39%....

Chronic stress is a well-established risk factor for cardiometabolic disease. Caregiving for individuals with cancer is perceived as a chronic stressor yet research on the risk for cardiometabolic disease in this population, opposed to the elderly and those with Alzheimer’s disease, is limited. Additionally, few studies have explored the early physiological changes that occur in family caregivers suggesting an elevated risk for illness. This cross-sectional study was designed to examine levels of cardiometabolic risk biomarkers...

A stereo interplanting system with foxtail millet beneath chestnut trees is an effective planting method to raise the utilization of land in chestnut orchards, increase yields and improve quality of chestnut nuts. Consequently, exploration of genes involved in shade tolerance response in foxtail millet and breeding shade-tolerant varieties have become urgent issues. In this study, RNA-seq of leaf samples from two shade-tolerant varieties and three shade-intolerant varieties of foxtail millet at the booting stage was...

Neoproterozoic mafic dyke swarms are an important probe for reconstructing the evolutionary history of the Rodinia supercontinent. Here, we present detailed geochronological, geochemical, and Sr–Nd–Hf isotopic data to constrain the petrogenesis and geodynamic setting of Neoproterozoic mafic dyke swarms in the western Yangtze Block, South China. Petrological and zircon U–Pb dating studies reveal that the studied dykes mainly comprise subophitic-textured dolerite and intergranular dolerite with crystallization ages of ca. 823–817 Ma and ca. 795–794 Ma,...

Osteoporosis is a worldwide disease that seriously affects the quality of life and survival rate of the elderly. The detection of bone biomarkers will provide supplementary information on bone mineral density, contributing to the accurate diagnosis of osteoporosis and better health care for prevention. This study aimed to investigate the efficacy of oxidative stress markers—8-oxo-7,8-dihydroguanine (8-oxoGsn) and 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodGsn) in the assessment of osteoporosis. We conducted a cross-sectional study among menopausal women with a mean...

Capsicum chinense is one of the best ingredients for making chili sauces and extracting capsaicin. In this study, we identified 59 genes associated with shikimic acid, phenylpropane, unsaturated fatty acids, phenylalanine, valine, leucine, isoleucine and other metabolic pathways based on pepper genome. In the present study, 58 of the 59 genes involved in capsaicin synthesis were found to be unevenly distributed on 11 chromosomes, and several genes with the same number of exons and high...

Although cardiac disorder-related adverse events (AEs) have been reported in patients treated with aryl hydrocarbon receptor (AHR) agonists, their safety profiles remain unknown. Here, we identified significant cardiac disorders associated with AHR agonists and further evaluated their relevance. Database queries were performed using OpenVigil 2.1 and AEs voluntarily submitted to Food and Drug Administration Adverse Event Reporting System (FAERS) between 2004 and 2020 were included. This study based on the Medical Dictionary for Regulatory Activities...

Lamivudine is a first-line medication used for human immunodeficiency virus (HIV) treatment. To date, the population pharmacokinetics of lamivudine in Chinese HIV-infected adults have not been assessed. This study aimed to develop a population pharmacokinetic model for oral lamivudine in Chinese HIV-infected adults and to determine the optimal lamivudine dosage regimens. A total of 1113 samples, from 828 Chinese HIV-infected patients treated with lamivudine 300 mg every 24 hours, were pooled from two open-label, prospective...

Predicting omalizumab treatment response has been a challenge and significant aspect for selecting suitable severe allergic asthma patients for omalizumab use. To determine which domains of pretreatment baseline characteristics predict omalizumab treatment response among asthmatic patients. Electronic bases were searched for eligible studies that reported potential biomarkers that could predict omalizumab responsiveness and efficacy. Patients who accepted omalizumab treatment were stratified into responders and non-responders. WMD, OR, and their 95%CI were used to access the...

Despite their poor tolerance, weak opioids are still the most commonly-prescribed medicine for osteoarthritis (OA)-related pain. The objective of this network meta-analysis was to comparatively examine the efficacy and safety of weak opioids in OA treatment. Databases including PubMed, Embase, Cochrane Library and Web of Science were searched from inception to 4 April 2022 to retrieve randomized controlled trials (RCTs) comparing weak opioids with placebo or between one another in OA patients. Bayesian network meta-analysis...

Four new ionones and ionone glycosides (1–4) were isolated from the whole plant of Rehmannia piasezkii Maxim. Their planar structures as well as absolute configuration were confirmed via spectroscopic analysis, ECD calculation, and X-ray crystallography. Compounds 1–4 were tested for their cytotoxicity against five human tumor cell lines and ability to inhibit LPS-activated NO production in the BV2 cell line.
