ABSTRACT
The 24th European Academy of Dermatology and Venereology was held in Copenhagen, Denmark, from 7-11 October 2015. It has become Europe's biggest meeting of its kind with roughly 10,000 participants, approximately 3000 abstracts and about 180 exhibitors from all over the world. The organizers offer a venue for the latest cutting edge research and newest developments. Thus, their goal is to foster progress in clinical care and promote scientific excellence related to dermatovenereology for the benefit of patients with skin diseases.

Somatostatin (SRIF) exerts inhibitory effects on virtually all endocrine and exocrine secretions. Five distinct SRIF receptor subtypes (sst 1-5) have been identified. In contrast to the other subtypes, very little is known about specific functions of sst4. We investigated structure and regulation of the human sst4 gene. A genomic clone containing the 5' region of the sst4 gene was isolated. 1.5 kb of the promoter was sequenced and putative transcription factor binding sites were identified. The transcription start site was located 88 nucleotides upstream of the translation start site. A -984 sst4 promoter directed significant levels of luciferase expression in GH4 rat pituitary cells, Skut-1B endometrium cells, and BEAS-2B human bronchial epithelial cells, whereas only low activity was detected in JEG3 chorion carcinoma cells or COS-7 monkey kidney cells. A minimal -209 promoter allowed cell specific expression, its activity in COS-7 cells is not enhanced by co-transfection of the pituitary-specific transcription factor Pit-1. An enhancer element was localized between nt -459 and -984. We did not find any regulation of the sst4 promoter region analyzed by SRIF, forskolin, TPA, IGF-1, EGF, T3, glucocorticoids or 17beta-estradiol. These studies identify the 5' region of the sst4 gene. Furthermore, specific activity of the promoter in various cell lines is demonstrated.
