The serotonin transporter (5-HTT) gene contains a variable number tandem repeat (VNTR) domain within intron 2 that is often associated with a number of neurological conditions, including affective disorders. The implications of this polymorphism are not yet understood, however, we have previously demonstrated that the 5-HTT VNTR is a transcriptional(More)
Two distinct variable number tandem repeats (VNTRs) within the human serotonin transporter gene (SLC6A4) have been implicated as predisposing factors for CNS disorders. The linked polymorphic region in the 5'-promoter exists as short (s) and long (l) alleles of a 22 or 23 bp elements. The second within intron 2 (Stin2) exists as three variants containing 9,(More)
The serotoninergic pathways are possible targets for the action of lithium, a therapeutic agent for treatment of bipolar affective disorders. This study aimed to investigate the molecular mechanisms regulating human serotonin transporter gene (SLC6A4) expression by lithium and, specifically, the role of the variable number tandem repeat (VNTR) polymorphic(More)
Interleukin-22 (IL-22) is a proinflammatory cytokine that has been associated with the pathogenesis of inflammatory skin disorders. However, the impact of IL-22 on microRNA (miRNA) expression in epidermal keratinocytes is unknown. Here we show that IL-22 induces miR-184 in reconstituted human epidermis (RHE) and in the HaCaT keratinocyte cell line. Exposure(More)
