Previous studies have shown that high levels of PLK1 are expressed in HCC, and PLK1 inhibitors are being tested in clinical trials. However, the mechanisms, which regulate PLK1 expression in HCC, have not been clarified. Here, we show that induction of let-7b over-expression inhibits the PLK1-regulated luciferase activity in HEK-293T cells, and decreases the levels of PLK1 expression in HCC cells...
SLIT2 is a candidate tumor suppressor gene and recent studies have shown that SLIT2 expression is suppressed or reduced by hypermethylation in the promoter region in various cancers. The aim of this study was to investigate the association between SLIT2 promoter methylation and nasopharyngeal carcinoma (NPC) and its relative diagnostic ability for NPC. Bisulfite pyrosequencing technology was performed...
Galectin-3 plays an important role in modulating cardiac inflammation and fibrosis. It also takes part in the pathways underlying cardiac remodeling. Therefore, LGALS3 gene, encoding galectin-3 protein, is a promising candidate for the genetic study of dilated cardiomyopathy (DCM). To date, there has been no research evaluating the association between LGALS3 gene polymorphisms and the susceptibility...
Recent studies have revealed that long non-coding RNAs (lncRNAs) participate in vascular homeostasis and pathophysiological conditions development. But still very few literatures elucidate the regulatory mechanism of non-coding RNAs in this biological process. Here we identified lncRNA taurine up-regulated gene 1 (TUG1) in rat vascular smooth muscle cells (VSMCs), and got 4612bp nucleotide sequence...
The role of miR-335 in the regulation of chemosensitivity and radiosensitivity of small cell lung cancer (SCLC) was investigated. miR-335 was significantly downregulated in multi-drug-resistant SCLC H69AR and H446DDP cells compared with parental cells as detected by qRT-PCR. Then, we demonstrated the negative correlation between miR-335 expression and the chemo-radiosensitivity of SCLC cells, including...
Transcription factor nuclear factor of activated T cells c4 (NFATc4) is the best-characterized target for the development of cardiac hypertrophy. Aberrant microRNA-29 (miR-29) expression is involved in the development of cardiac fibrosis and congestive heart failure. However, whether miR-29 regulates hypertrophic processes is still not clear. In this study, we investigated the potential functions...
Low air pressure and low oxygen partial pressure at high altitude seriously affect the survival and development of human beings and animals. ECE1 is a recently discovered gene that is involved in anti-hypoxia, but the full-length cDNA sequence has not been obtained. For a better understanding of the structure and function of the ECE1 gene and to study its effect in Tibetan pig, the cDNA of the ECE1...
The reduced folate carrier (RFC1) plays a crucial role in mediating folate delivery into a variety of cells. RFC1 polymorphism (A80G) has been reported to be associated with increased risk of neural tube defects (NTDs). However, results derived from individually underpowered studies are conflicting. We performed a systematic search of MEDLINE and EMBASE databases and carried out a meta-analysis on...
N-Myc downstream-regulated gene 1 (ndrg1) is up-regulated in N-Myc knockout mouse embryos. The human NDRG family consists of 4 highly homologous members and human Ndrg1 exhibits approximately 94% homology with mouse ndrg1. However, the regulatory mechanism of NDRG1 via Myc repression is as yet unknown. We previously identified human NDRG2 and demonstrated that this gene is transcriptionally down-regulated...
A metalloprotease and disintegrin (ADAM) is a family of membrane-anchored proteins and all family members have a multi-domain structure containing a zinc metalloprotease domain and a disintegrin domain that may serve as an integrin ligand. Here we reported two novel mammalian transcripts of Adam23, named Adam23β and Adam23γ, to be involved in the development and functional activities of mammalian...
