This study aimed to explore the roles of microRNAs (miRNAs) in calf rumen development during early life. Rumen tissues were collected from 16 calves (8 at pre-weaning and 8 at post-weaning) for miRNA-sequencing, differential expression (DE), miRNA weighted gene co-expression network (WGCNA) and miRNA-mRNA co-expression analyses. 295 miRNAs were identified. Bta-miR-143, miR-26a, miR-145 and miR-27b were the most abundantly expressed. 122 miRNAs were significantly DE between the pre- and post-weaning periods and the most up- and down-regulated miRNAs were bta-miR-29b and bta-miR-493, respectively...

Prostate cancer is the most common cancer among men in the western world. Clinical practice is continuously challenged by the pitfalls of the available diagnostic tools. microRNAs may represent promising biomarkers in many types of human cancers, including prostate cancer. The aim of this study was to investigate microRNA expression in tumour tissue and matched plasma in a cohort of patients with primary metastatic prostate cancer. The relative expression of 12 microRNAs was assessed in diagnostic needle biopsies from the prostate and matched plasma samples in two prospective cohorts (screening cohorts) comprising 21 patients with metastatic prostate cancer and 25 control patients...

Ascospores act as the primary inoculum of Fusarium graminearum , which causes the destructive disease Fusarium head blight (FHB), or scab. MicroRNAs (miRNAs) have been reported in the F. graminearum vegetative stage, and Fgdcl2 is involved in microRNA-like RNA (milRNA) biogenesis but has no major impact on vegetative growth, abiotic stress or pathogenesis. In the present study, we found that ascospore discharge was decreased in the Fgdcl1 deletion mutant, and completely blocked in the double-deletion mutant of Fgdcl1 and Fgdcl2 ...

Osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) is essential for the human bone formation, and emerging evidence shows that long non-coding RNAs (lncRNAs) play important roles in hBMSC osteogenic differentiation. MALAT1 is often regarded as a tumor-related lncRNA, but its function in mesenchymal stem cell differentiation remains to be defined. In this study, we aimed to investigate whether MALAT1 regulates Osterix (Osx) expression by sponging miR-143 to promote hBMSC osteogenic differentiation...

MiR-1 and miR-143 are frequently reduced in human prostate cancer (PCa), while miR-141 and miR-21 are frequently elevated. Consequently, these miRNAs have been studied as cell-autonomous tumor suppressors and oncogenes. However, the cell-type specificity of these miRNAs is not well defined in prostate tissue. Through two different microdissection techniques, and droplet digital RT-PCR, we quantified these miRNAs in the stroma and epithelium of radical prostatectomy specimens. In contrast to their purported roles as cell-autonomous tumor suppressors, we found miR-1 and miR-143 expression to be predominantly stromal...

Epithelial ovarian cancer (EOC) is one of the most lethal malignancies of the female reproductive organs. Increasing evidence has revealed that long non‑coding RNAs (lncRNAs) participate in tumorigenesis. Metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is an lncRNA and plays a role in various types of tumors. However, the function of MALAT1 on cellular behavior in EOC remains unclear. The current study explored the expression of MALAT1 in ovarian cancer tissues and in EOC cell lines. Quantitative RT‑PCR analysis revealed that the expression of MALAT1 was higher in human ovarian malignant tumor tissues and EOC cells than in normal ovarian tissues and non‑tumorous human ovarian surface epithelial cells, respectively...

MiR-143 is an miRNA with the function of specifically inhibiting the insulin-AKT pathway via the downregulation of oxysterol-binding protein-related protein 8 (ORP8), thus resulting in the inhibition of AKT phosphorylation, insulin tolerance, and final development of type II diabetes mellitus (T2DM). Aerobic exercise can prevent T2DM by downregulating miR-143. However, the underlying mechanisms for exercise-induced change of miR-143 remain unclear. In the present study, we will summarize the involvement of miR-143 in regulating the development of T2DM and the underlying mechanisms for potential diagnosis, prevention, and treatments, including exercise intervention for T2DM by targeting miR-143...

Propofol, a widely used intravenous anesthetic, was previously considered as a neuroprotective agent. Recently, however, accumulating evidence suggests that it may cause neurotoxicity, especially in the development of neural stem cells (NSCs). The potential mechanisms contributing to propofol-induced neurotoxicity during neurogenesis, such as those involving microRNAs (miRNAs), are still unknown. In this study, a total of 27 differentially expressed miRNAs were identified in our initial screen and 6 miRNAs were validated by qRT-PCR...

Genetic studies have managed to explain many cases of familial amyotrophic lateral sclerosis (ALS) through mutations in several genes. However, the cause of a majority of sporadic cases remains unknown. Recently, epigenetics, especially miRNA studies, show some promising aspects. We aimed to evaluate the differential expression of 10 miRNAs, including miR-9, miR-338, miR-638, miR-663a, miR-124a, miR-143, miR-451a, miR-132, miR-206, and let-7b, for which some connection to ALS was shown previously in ALS culture cells, animal models or patients, and in three miRNA host genes, including C1orf61 (miR-9), AATK (miR-338), and DNM2 (miR-638), in leukocyte samples of 84 patients with sporadic ALS...

Our previous study showed that progesterone (P4) can specifically regulate the expression of some microRNAs (miRNAs) in endometrial epithelium. In the present study, we verified the P4-dependent expression of miR-145/miR-143 in endometrial epithelial cells, explored the regulative mechanism of the P4 receptor (PR), and investigated their effects on the proliferation of endometrial epithelial cells. Our results showed that P4 can induce the expression of miR-145/143 in endometrial epithelial cells by acting on the PR A subtype...

The prevalence of overweight and obesity in the population, along with their associated complications, is a major factor contributing to increased morbidity and mortality in developed countries. The liver is a vital organ for maintaining metabolic homeostasis, especially in the adjustment periods in fasting and feeding. Per-Arnt-Sim (PAS) kinase (PASK) controls glucose homeostasis and energy metabolism in response to nutritional status. PASK-deficient mice with a high-fat diet (HFD) resist the development of obesity and hepatic steatosis, with improved insulin sensitivity...

Hypoxia and expression of hypoxia-related biomarkers are associated with disease progression and treatment failure in prostate cancer (PCa). We have reported that exosomes (nanovesicles of 30-150 nm in diameter) secreted by human PCa cells under hypoxia promote invasiveness and stemness in naïve PCa cells. Here, we identified the unique microRNAs (miRNAs) loaded in exosomes secreted by PCa cells under hypoxia. Using TaqMan® array microRNA cards, we analyzed the miRNA profile in exosomes secreted by human PCa LNCaP cells under hypoxic (ExoHypoxic ) and normoxic (ExoNormoxic ) conditions...

Accumulating data indicates that certain microRNAs (miRNAs or miRs) are differently expressed in samples of tumors and paired non-tumorous samples taken from the same patients with colorectal tumors. We previously reported to clarify the relationship between the expression of the miRNAs and the endoscopic morphological appearance of the colorectal tumors. In this report, we focused on colorectal adenoma (tubular or tubulovillous adenoma), or tubular early carcinoma or type 2 adenocarcinoma, familial adenomatous polyposis (FAP), ulcerative colitis-associated tumor (UCAT), and sessile serrated adenoma/polyp (SSA/P)...
