Disulfiram (DSF) is an anti-alcoholism medication with superior antitumor activity and clinical safety; its mechanisms in gastric cancer (GC) have not been fully explored. In the present work, low nontoxic concentrations of copper (Cu) ions substantially enhanced DSF's activity, inhibiting proliferation growth GC cell lines. DSF/Cu elevated generation reactive oxygen species (ROS), apoptosis was induced ROS-dependent manner. This process might involve primary inhibition by through induction...

Abstract Systemic immune-inflammation index (SII) emerged as a biomarker of chronic inflammation and an independent prognostic factor for many cancers. We aimed to investigate the associations SII level with total cause-specific mortality risks in general populations, potential modification effects lifestyle-related factors on above associations. In this study, we included 30,521 subjects from Dongfeng-Tongji (DFTJ) cohort 25,761 National Health Nutrition Examination Survey (NHANES)...

Abstract Prostate cancer (PCa) causes significant mortality and morbidity, with advanced metastasis. WNT signaling is a promising therapeutic target for metastatic PCa. GIPC2 GIPC1 paralog involved in pathways associated tumor progression, but its role PCa metastasis remains unclear. Herein, we demonstrated that high expression tissues was significantly distant poor prognosis. Functional studies due to CpG-island demethylation promoted increased capabilities of cells. Conversely, silencing...

Breast cancer (BC) is the most common gynecologic tumor worldwide where aberrant expression of microRNAs (miRNAs) frequently involved. Here, we evaluated function miR-375 on BC development and molecules implicated. Differentially expressed genes between paired normal tissues from patients were screened out by microarray analyses. was abundantly in cells, it correlated with poor prognosis patients. Downregulation introduced into cell lines MCF-7 HCC1954, after which viability, colony...

Observational epidemiological studies have reported the associations of high body mass index (BMI) with elevated serum uric acid (UA) level and increased risk postmenopausal breast cancer. However, whether UA is causally induced by BMI functioned in BMI-breast cancer relationship remains unclear.To elucidate causality direction between UA, bidirectional Mendelian randomization (MR) analyses were performed using summarized data from largest Asian genome-wide association (GWAS) carried out...

Tight junctions regulate paracellular permeability, create the luminal fluid microenvironment of blood vessels and digestive tract, also form protective barrier in stratified epithelium including epidermis. Claudins are integral membrane proteins at tight a multigene family composed least 24 members, but knowledge subcellular localization each claudin is still fragmentary. We performed RT-PCR for fifteen species to examine mRNA expression various mouse tissues, focused on investigating...

Circulating white blood cell (WBC) counts have been related to lung function impairment, but causal relationship was not established. We aimed evaluate independent effects and relationships of WBC subtypes with function.The 19,159 participants from NHANES 2011-2012 (n = 3570), coke-oven workers (COW, n 1762) Dongfeng-Tongji (DFTJ, 13,827) cohorts were included in the observational studies.

Administration of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) is believed to be an effective method for treating neurodevelopmental disorders. In this study, we investigated the possibility hUC-MSCs treatment neonatal hypoxic/ischemic brain injury associated with maternal immune activation and underlying mechanism. We established rat models by exposing pregnant rats lipopolysaccharide on day 16 or 17 pregnancy. Rat offspring were intranasally administered postnatal 14....
