P roper cholesterol homeostasis requires a complex network of sterol-sensing proteins, membrane dynamics, and extensive regulation of transcription, translation, posttranslation modifications, and protein turnover. Together, multilayered regulatory modules control 3 key processes to balance cellular cholesterol levels: de novo cholesterol biosynthesis, cholesterol uptake through lipoprotein rec...

Atherosclerosis is driven by intimal arterial macrophages accumulating cholesterol. also predominantly occurs in areas consisting of proinflammatory endothelial cells. At time writing, there are no available clinical treatments that precisely remove excess cholesterol from lipid-laden macrophages. Delivery anti-miR-33a-5p to has been shown increase apoAI-mediated efflux via ABCA1 upregulation b...

MicroRNAs (miRNAs) are single-stranded RNA molecules which regulate gene expression at the post-transcriptional level and several miRNAs have been found to be associated with some types of cancer. We sought to identify the expression and involvement of miRNAs in supraglottic carcinoma tissues compared with normal tissues and to determine whether miRNA expression is predictive of disease. Unsupe...

Introduction There are currently no diagnostic or treatment-guiding biomarkers for major depressive disorder (MDD). Microribonucleic acids (miRNA) may facilitate understanding the reorganisation of gene expression networks in MDD. Identifying miRNA and target mRNA pathways that contribute to MDD open new therapeutic avenues, such as inhibiting endogenous administering exogenous miRNA. Objective...

Numerous studies have examined the role of microRNAs (miRNAs) in cell homeostasis and cardiovascular disease and have markedly improved our understanding of RNA biology in general and the potential role of miRNAs in atherosclerosis. In atherosclerosis, several miRNAs, such as miR-33a,b, miR-92a, miR-126 and others, have been identified that are relevant mediators of pathological processes, incl...

MicroRNAs (miRNAs) have within the past decade emerged as key regulators of metabolic homoeostasis. Major tissues in intermediary metabolism important during development of the metabolic syndrome, such as β-cells, liver, skeletal and heart muscle as well as adipose tissue, have all been shown to be affected by miRNAs. In the pancreatic β-cell, a number of miRNAs are important in maintaining the...

OBJECTIVE The ATP-binding cassette transporter A1 (ABCA1) protein maintains cellular cholesterol homeostasis in several different tissues. In the liver, ABCA1 is crucial for high-density lipoprotein biogenesis, and in the pancreas ABCA1 can regulate insulin secretion. In this study, our aim was to identify novel microRNAs that regulate ABCA1 expression in these tissues. APPROACH AND RESULTS W...

Chemoresistance is one of the main factors treatment failure cervical cancer (CC). Here, we intended to discover role and mechanism miR-509-5p in paclitaxel chemoresistance CC cells. RT-PCR was conducted verify miR-509-3p expression. HCC94 C-33A paclitaxel-resistant cell models were constructed. Additionally, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay flow cytometr...

Type 2 diabetes is a major public health concern worldwide. Xylobiose (XB) consists of two molecules of d-xylose and is a major disaccharide in xylooligosaccharides that are used as prebiotics. We hypothesized that XB could regulate diabetes-related metabolic and genetic changes via microRNA expression in db/db mice. For six weeks, C57BL/KsJ-db/db mice received 5% XB as part of the total sucros...
