Kresoxim-methyl (KM) is a broad spectrum strobilurin fungicide that has been used widely on crops around the world. In the present study, we aimed to investigate the toxic effects of KM using various sublethal endpoints during zebrafish (Danio rerio) larval development. Results showed that the LC50 values of KM to zebrafish at multiple life stages (embryo, larvae, juvenile and adult) were 0.340, 0.224, 0.328 and 0.436 mg/L, respectively. The transcription patterns of 45 genes involved in hypothalamic-pituitary-thyroid/gonadal (HPT/HPG) axis, oxidative stress and apoptosis revealed KM could affect zebrafish larval development at multiple pathways...

BACKGROUND: The pedicled greater omentum has been shown to offer benefit in ischemic heart disease for both animal models and human patients. The impact of cardio-omentopexy in a pressure overload model of left ventricular hypertrophy (LVH) is unknown. METHODS: LVH was created in rats by banding the ascending aorta after right thoracotomy (n=23). Sham surgery was performed in 12 additional rats. Six weeks post-banding, surviving LVH rats were assigned to cardio-omentopexy via left thoracotomy (LVH+Om, n=8) or sham left thoracotomy (LVH, n=8)...

Accumulating research works have reported that long noncoding RNAs (lncRNAs) are involved in various cancers, including cervical cancer. LncRNA DGCR5 has been identified in many cancers. However, the biological role of DGCR5 in cervical cancer remains barely known. We aimed to investigate the biological function of DGCR5 in cervical cancer progression. Here, in our current study, we observed that DGCR5 was downregulated in human cervical cancer cell lines (MS751, SiHa, HeLa, and HT-3) compared with the primary normal cervical squamous cells (NCSC1 and NCSC2)...

Hypoxia promotes tubulointerstitial inflammation in the kidney. Although hypoxia inducible factor-1α (HIF-1α) is a master regulator of the response to hypoxia, the exact mechanisms through which HIF-1α modulates the induction of tubulointerstitial inflammation are still largely unclear. We demonstrated tubulointerstitial inflammation and increased tubular HIF-1α expression in murine models of ischemia/reperfusion injury and unilateral ureteral obstruction. Increased expression of HIF-1α in tubular epithelial cells was associated with selective shedding of microRNA-23a (miRNA-23a)-enriched exosomes in vivo and systemic inhibition of miRNA-23a prior to ischemia/reperfusion injury attenuated tubulointerstitial inflammation...

Vascular remodeling is mainly caused by excessive proliferation of vascular smooth muscle cells (VSMCs). Noncoding RNAs (ncRNAs) have emerged as important regulators in diverse pathological processes. Previous work has shown the functions and mechanisms of long noncoding RNA H19 (LncRNA H19) on VSMCs. As long noncoding RNAs (lncRNAs) are complex in their mechanisms of action, the aim of the study is to identify if there are any other molecular mechanisms of LncRNA H19 on VSMCs. In vivo studies demonstrated that cyclin D1 was overexpressed in neointima of balloon-injured artery...

Hyperuricemia is an important risk factor for vascular inflammation, yet the potential mechanisms of uric acid (UA) in endothelial cells are not well understood. UA has been found to stimulate renin-angiotensin system (RAS) activation in human umbilical vein endothelial cells (HUVECs). (Pro)renin receptor ((P)RR) is widely expressed in endothelial cells and able to induce RAS activation. Whether UA-induced endothelial cell inflammation is via up-regulating (P)RR remained unknown. Primary HUVECs were cultured and treated with UA, under the condition of (P)RR or AT1 silencing...
