Gonadotropin-releasing hormone (GnRH) is exclusively expressed in a unique population of hypothalamic neurons that controls reproductive function. GnRH gene expression is highly dynamic. Its transcriptional activity is regulated in a complex spatiotemporal manner during embryonic development and postnatal life. Although a variety of transcription factors have been identified as regulators of Gn...
Nestin is a molecular marker for neural progenitor cells. Rat and human nestin genes possess a central nervous system-specific enhancer within their second introns. However, the transcription factors that bind to the nestin enhancer have not been fully elucidated. Here, we show that the second intron of the mouse nestin gene is sufficient to drive reporter gene expression in the developing nerv...
IL-13 is a central effector of Th2-mediated allergic inflammation and is critical for the induction of IgE synthesis. Common IL13 variants are associated with allergy phenotypes in populations of distinct ethnic background. We recently demonstrated that IL13 expression by human CD4+ T cells is paralleled by extensive IL13 locus remodeling, which results in the appearance of multiple DNase I hyp...
Linagliptin is a highly potent dipeptidyl peptidase-4 (DPP-4) inhibitor approved for the treatment of type 2 diabetes. Unlike other DPP-4 inhibitors, linagliptin is cleared primarily via the bile and gut. We used a panel of stably and transiently transfected cell lines to elucidate the carrier-mediated transport processes that are involved in linagliptin disposition in vivo and to assess the po...
Introduction: Organic cation transporters collectively called OCTs belong to three gene families (SLC22A1 OCT1, SLC22A2 OCT2, SLC22A3 OCT3, SLC22A4 OCTN1, SLC22A5 OCTN2, SLC29A4 PMAT, SLC47A1 MATE1, and MATE2-K). transport structurally diverse drugs with overlapping selectivity. Some were shown be critically involved in pharmacokinetics therapeutic efficacy of cationic drugs. Drug-drug interact...
For the elimination of environmental toxins and metabolic waste products, the body is equipped with a range of broadspecificity transporters that are generally present in the liver, kidney, and intestine. The polyspecific organic cation transporters OCT1, 2, and 3 (SLC22A1-3) mediate the facilitated transport of a variety of structurally diverse organic cations, including many drugs, toxins, an...
The mechanism of action of retinoic acid (RA) is of broad relevance to cell and developmental biology, nutrition, and cancer chemotherapy. RA is known to induce expression of the Burkitt's lymphoma receptor 1 (BLR1) gene which propels RA-induced cell cycle arrest and differentiation of HL-60 human myeloblastic leukemia cells, motivating the present analysis of transcriptional regulation of blr1...
