MicroRNAs (miRNAs) are small non-coding RNA molecules that are involved in a variety of cellular functions. Single nucleotide polymorphisms (SNPs) have been identified in mature miRNAs (mmSNPs), some of which have been linked to cancer risk; however, it is unclear which mmSNPs contribute to the susceptibility to thyroid tumors. In the present study, we examined the influence of selected mmSNPs on...
To investigate the association of single nucleotide polymorphism (SNP) rs4355801 near osteoprotegerin (OPG) gene and rs3736228 in low-density lipoprotein receptor-related protein 5 (LRP5) gene with metabolic phenotypes [body mass index (BMI), waist–hip ratio, glucose, total cholesterol (CHO), and triglyceride], we carried out a population-based association study in Uyghur population living in Xinjiang...
Through its transcriptional activities, the proto-oncoprotein c-jun can regulate cellular proliferation, survival, and differentiation. We have established a novel yeast assay that screens for repressors of c-jun transcriptional activity. This screen led to the identification of a ubiquitously expressed novel RING zinc finger protein, termed Makorin RING zinc finger protein 1 (MKRN1), recently shown...
Mammaglobin (SCGB2A2) is a breast-specific member of the secretoglobin (SCGB) gene family. SCGB2A2 has previously been found overexpressed in breast tumors but possible associations between its expression and established prognostic tumor characteristics such as the levels of estrogen and progesterone receptors have not yet been investigated. We evaluated SCGB2A2 expression at the mRNA and at the protein...
The human androgen receptor (hAR) is a member of the nuclear receptor superfamily and functions as a ligand-inducible transcription factor. We have previously proposed that c-Jun mediates the transcriptional activity of this receptor. The modular nature of hAR was used in this study to generate several fusions with the heterologous DNA-binding domain of the yeast transcription factor GAL4 in an attempt...
Upon binding retinoic acid (RA), the retinoic acid receptors (RARs) are able to positively and negatively regulate transcription. It has been shown that the DNA-binding domain and carboxy terminus of RARs are necessary for the ligand-dependent ability of the receptor to repress AP-1 transcriptional activity. A fusion of these two regions, shown to constitutively inhibit AP-1 activity, was used in...
