BACKGROUND The mechanisms of lipid raft regulation by microRNAs in breast cancer are not fully understood. This work focused on the evaluation and identification of miR-3908, which may be a potential biomarker related to the migration of breast cancer cells, and elucidates lipid-raft-regulating cell migration in breast cancer. METHODS To confirm the prediction that miR-3908 is matched with Ad...

BACKGROUND AND AIMS To explore the molecular mechanisms of miR-886-5p in breast cancer., we examined roles in inhibiting growth and migration of MCF-7 cells. METHODS MiR-886-5p mimics and inhibitors were used to express or inhibit MiR-886-5p, respectively, and MTT and clone formation assays were used to determine the survival and proliferation. Hoechst 33342/ PI double staining was applied to...

OBJECTIVES MicroRNA-7 (miR-7) is highly connected to cancerous cell proliferation and metastasis. It is also involved in myocardial ischemia-reperfusion (I/R) injury and is upregulated in cardiomyocyte under simulated I/R (SI/R). We aimed to investigate the role of miR-7 during myocardial I/R injury in vitro and in vivo and a possible gene target. METHODS AND RESULTS Real-time PCR revealed th...

Multidrug resistance (MDR) correlates with treatment failure and poor prognosis among breast cancer patients. This study was aimed to investigate the possible mechanism by which microRNA-130b-3p (miR-130b) mediates the chemoresistance and proliferation of breast cancer. MiR-130b was found to be up-regulated in tumor tissues versus adjacent tissues of breast cancer, as well as in adriamycin (ADR...

Breast cancer (BC) is the most common cause of death in women throughout the world. Although microRNAs (miRNAs) have been identified as novel regulators in carcinogenesis, there are still abundant hidden treasure needed to be excavated. In the present study, we found that miR-519d expression was remarkably decreased in both human BC tissues and MCF-7 cells. CCK8 and 5-Ethynyl-2'-deoxyuridine (E...

Fenhexamid and fludioxonil are antifungal agents used in agricultural applications, which are present at measurable amounts in fruits and vegetables. Fenhexamid and fludioxonil showed endocrine disruptor activity as antiandrogens in an androgen receptor reporter assay in engineered human breast cancer cells. Little is known about how environmental chemicals regulate microRNA (miRNA) expression....

Dysfunctional microRNA (miRNA) networks contribute to inappropriate responses following pathological stress and are the underlying cause of several disease conditions. In pancreatic β cells, miRNAs have been largely unstudied and little is known about how specific miRNAs regulate glucose-stimulated insulin secretion (GSIS) or impact the adaptation of β cell function to metabolic stress. In this...

The use of glucagon-like peptide-1 analogues, such as liraglutide, as hypoglycemic drugs has been widely employed in clinical practice. Liraglutide is reported to exert potential anti‑breast cancer effects, however the specific mechanisms of this action remain unknown. In the present study, MCF‑7 human breast cancer cells were cultured in vitro and treated with various concentrations of liraglu...

objective(s):an earlier meta-analysis on gene expression data derived from four microarray, two cdna library, and one sage experiment had identified rgs5 as one of only ten non-housekeeping genes that were reported to be expressed in human trabecular meshwork (tm) cells by all studies. rgs5 encodes regulator of g-protein signaling-5. the tm tissue is the route of aqueous fluid outflow, and is r...
