The aims of the present study were to identify the expression profile of microRNA (miR)-143/145 in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC), explore its association with prognosis and investigate whether the serum miR-143/145 expression levels may serve as a diagnostic indicator of HBV-associated HCC. The microRNA (miRNA) chromatin immunoprecipitation dataset was obtain...

We examined whether lenalidomide exposure up-regulates miRNAs and mRNAs, previously shown to play a role in the disease phenotype of del(5q) myelodysplastic syndrome, in pre-treatment CD34(+) marrow cells. We hypothesized that increased expression would predict for clinical response. Changes in miR-143, miR-145, miR-146a, miR-146b, miR-378, miR-584, SPARC and RPS14 were examined in del(5q) (n=1...

RATIONALE High-angiotensin-converting enzyme (ACE)-levels are associated with cardiovascular disease, but little is known about the regulation of its expression. OBJECTIVE To assess the molecular mechanisms regulating endothelial ACE expression focusing on the role of the AMP-activated protein kinase (AMPK) and miR-143/145. METHODS AND RESULTS Shear stress decreased ACE expression in cultur...

Epidermal growth factor receptors (EGFR) contribute to colonic tumorigenesis in experimental models of colon cancer. We previously showed that EGFR was also required for colonic tumor promotion by Western diet. The goal of this study was to identify EGFR-regulated microRNAs that contribute to diet-promoted colonic tumorigenesis. Murine colonic tumors from Egfr(wt) and hypomorphic Egfr(wa2) mice...

Objective To evaluate the effects of environmental factors and microRNAs (miRNAs) (miR-126, miR-143, and miR-145) on the risk of coronary heart disease (CHD). Methods A frequency-matched case-control study (450 patients, 450 controls) was conducted from April 2014 to December 2016 in Fuzhou City, China. Environmental factors were investigated using a self-administered questionnaire, and the e...

BACKGROUND Prostate cancer has become a serious threat to the life of patients. microRNAs are small non-coding RNA molecules that regulate the growth and apoptosis of cells. We aimed to investigate the regulation and mechanism of microRNA (miR-143) in the proliferation and apoptosis of prostate cancer LNCap cells. MATERIAL AND METHODS miR-143 and control scramble miRNA were synthesized and resp...

MicroRNAs (miRNAs) are endogenously expressed 20–24 nucleotide RNAs thought to repress protein translation through binding to a target mRNA (1–3). Only a few of the more than 250 predicted human miRNAs have been assigned any biological function. In an effort to uncover miRNAs important during adipocyte differentiation, antisense oligonucleotides (ASOs) targeting 86 human miRNAs were transfected...

Elevated levels of insulin-like growth factor-I (IGF-I) are associated with carcinogenesis and cancer progression. However, the molecular mechanisms by which IGF-I promotes prostate cancer development remain to be elucidated. Docetaxel chemotherapy is an important therapeutic strategy in many types of human cancers including prostate cancer. In this study, we showed that IGF-I rendered PC-3 and...

Osteosarcoma is one primary malignant bone tumor that commonly occurs in children and teenagers. Its high malignancy, invasiveness and metastasis all lead to unfavorable prognosis even with combined treatment. Cisplatin is a common chemotherapy agent in treating various solid tumors including ovarian, pulmonary, nasopharyngeal, esophageal, thyroid cancers and osteosarcoma, but leaving its mecha...

background: absent in melanoma 2 (aim2) is an intracellular microbial dsdna sensor which plays an important role in production of proinflammatory cytokines through apoptosis associated speck-like protein containing a caspase activation and recruitment domain (asc) and caspase-1. micro-rnas (mirnas) play important roles in regulation of immune related genes. however, there is little information ...
