miRNAs can play vital role in migration, invasion and proliferation in Squamous cell carcinoma of head and neck (SCCHN). In our study, we attempted to validate the expression and function of miR-1275 in SCCHN, and we also identified the mechanism by which miR-1275 affects migration, invasion and proliferation of SCCHN.Real-time polymerase chain reaction (RT-PCR) was employed to evaluate the expression...
Waardenburg syndrome type IV (WS4) is a rare genetic disorder, characterized by auditory–pigmentary abnormalities and Hirschsprung disease. Mutations of the EDNRB gene, EDN3 gene, or SOX10 gene are responsible for WS4. In the present study, we reported a case of a Chinese patient with clinical features of WS4. In addition, the three genes mentioned above were sequenced in order to identify whether...
Cten is a focal adhesion molecule and a member of the tensin family. Its expression is highly enriched in the prostate and placenta, suggesting that cten gene might be closely associated with mammalian species. Recent studies have reported that cten expression is frequently up-regulated in a variety of cancers and its levels appear to correlate with tumorigenicity. Here, we have (1) analyzed cten...
Both transcription factors (TFs) and microRNAs (miRNAs) regulate gene expression. TFs activate or suppress the initiation of the transcription process and miRNAs regulate mRNAs post-transcriptionally, thus forming a temporally ordered regulatory event. Ectopic expression of key transcriptional regulators and/or miRNAs has been shown to be involved in various tumors. Therefore, uncovering the coregulation...
We previously isolated, from the earliest population of CD34+ hematopoietic progenitors that form in the aorta of the human embryo, a partial DNA complementary to RNA (cDNA) sequence that was later identified as the human homologue of rat sucrose non-fermenting protein (SNF-1) related kinase (rSNRK), a novel SNF-1-related kinase previously characterized in the rat. In the present study we report the...
The determinants governing the self-catalyzed splicing and cleavage events by a mini-intein of 154 amino acids, derived from the dnaB gene of Synechocystis sp. were investigated. The residues at the splice junctions have a profound effect on splicing and peptide bond cleavage at either the N- or C-terminus of the intein. Mutation of the native Gly residue preceding the intein blocked splicing and...
