microrna30a

BACKGROUND: The aim of this study was investigated if estrogen deficiency during puberty affects the expression of miRNA30a and miRNA503 in maxillary and mandibular growth centers, and also evaluated if ERα and ERβ are correlated with miRNA30a and miRNA503 expressions. METHODS: Samples from 12 female Wistar rats randomized into experimental group (OVX) and control group (SHAM). At an age of 45 days animals were euthanized for miRNA expression analyses. RT-qPCR was performed to determine miRNA30a and miRNA503 expression in growth sites: midpalatal suture, condyle, mandibular angle, symphysis/parasymphysis and coronoid process...

OBJECTIVE: To establish obese rat models by high-fat diet, screen microRNAs by microarray in the omental adipose tissue, and find out differential expression of microRNAs in obese rats, for further understanding the role of microRNAs as regulating molecules in obesity-induced lipid metabolism disorders. METHODS: 40 male SD rats were randomly divided into normal diet group and high-fat diet group, respectively. After fed for 8 weeks, rats were weighted, measured length and other characteristics were observed...

Dysregulation of transcription via the Wnt/β-catenin signaling pathway underlies the pathogenesis of a wide variety of frequent human cancers. These include epithelial carcinomas such as colorectal cancer and hematologic malignancies such as multiple myeloma. Thus, the Wnt/β-catenin in pathway potentially offers an attractive target for cancer therapy. This approach, however, has thus far proved challenging because the pathway plays a number of critical roles in physiologic homeostasis, [corrected] and because drugs that broadly target the pathway have unacceptable side effects...

Precise spatiotemporal regulation of the SIX1 homeoprotein is required to coordinate vital tissue development, including myogenesis. Whereas SIX1 is downregulated in most tissues following embryogenesis, it is re-expressed in numerous cancers, including tumors derived from muscle progenitors. Despite crucial roles in development and disease, the upstream regulation of SIX1 expression has remained elusive. Here, we identify the first direct mechanism for Six1 regulation in embryogenesis, through microRNA30a (miR30a)-mediated repression...
