p27(kip1) (p27) is a cdk-inhibitory protein with an important role in the proliferation of many cell types. SCF(Skp2) is the best studied regulator of p27 levels, but Skp2-mediated p27 degradation is not essential in vivo or in vitro. The molecular pathway that compensates for loss of Skp2-mediated p27 degradation has remained elusive. Here, we combine vascular injury in the mouse with genome-w...

MicroRNA (miR)-221 and miR-222 are frequently upregulated in various types of human malignancy including glioblastoma. Previous studies have identified some targets of miR-221 and miR-222, such as p27 and p57. Inter-relationship between miR-221 and miR-222 expression and global mRNA expression remains elusive. Here we knocked down miR-221 and miR-222 expression and found 158 differentially expr...

The pros and cons of using anaesthesia when handling fish in connection with experiments are debated. A widely adopted practice is to wait thirty minutes after anaesthesia before behavioural observations are initiated, but information about immediate effects of a treatment is then lost. This is pertinent for responses to acute stressors, such as acid injection in the acetic acid pain test. Howe...

microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at the post-transcriptional level. Their roles in regulating the responses of Schwann cells (SCs) to injury stimuli remain unexplored. Here we report dynamic alteration of miRNA expression following rat sciatic nerve injury using microarray analysis. We harvested the proximal nerve stumps and identified 77 miRNAs that sh...

The aim of the research was to examine the expression level of microRNA221/222 (miR-221/222) in the serum of patients with type 2 diabetes mellitus (T2DM) who are also diagnosed with post-menopausal breast cancer. We aimed to evaluate the differences in microRNA expression in patients with T2DM alone, patients with post-menopausal breast cancer alone, and patients with both T2DM and post-menopa...

Mycoplasma pneumoniae pneumonia (MPP) is a type of induced by M. (MP) infection. The present study investigated the effect long non‑coding RNA growth arrest‑specific 5 (GAS5) in MPP and underlying molecular mechanism this. expression GAS5, microRNA‑222‑3p, (miR‑222‑3p) tissue inhibitor metalloproteinases‑3 (TIMP3) was using reverse transcription‑quantitative PCR. Lipid‑associated m...

The epithelial-to-mesenchymal transition (EMT) is a highly conserved physiological program involved in development and tissue repair; however, its aberrant activation has been implicated in accelerating the progression of a variety of cancers. In breast cancer, the microRNAs (miRNAs) miR-221 and miR-222 (miR-221/222) are differentially expressed in the clinically more aggressive basal-like subt...
