Study of expression of the nuclear receptor nhr-97 in Caenorhabditis elegans
Boušová, Kristýna ; Stiborová, Marie (advisor) ; Vaněk, Ondřej (referee)
Nuclear hormone receptors (NHR) are important transcription factors that regulate development and metabolism in the large group of animals. Caenorhabditis elegans contains 284 nuclear receptors, which is unusually large amount compared to receptors of Drosophila melanogaster (18) and humans (48). 15 receptors of the C. elegans have homologous receptor structure with receptors of D. melanogaster and mammals. The remaining 269 NHR are specific to nematodes and belong to the group of supplementary nuclear receptors (SupNRs), the evolutionary precursor of the HNF4 - an important transcription factor in humans. In this work we describe the nuclear hormone receptor nhr-97 C. elegans, whose expression and function have not yet been studied. The gene is encoded in the genome of C. elegans and is among SupNRs. Nhr-97 consists of two isoforms A and B, whose expression in C. elegans tissues is different. Localization of gene expression in vivo was determined using lines expressing nhr-97:: GFP. For the A isoform expression of nhr-97::GFP was localized in neurons in the pharynx and the tail, in the intestine and hypodermis, in isoform B in the pharynx, in neurons around the corpus of pharynx, the head mesodermal cell and in anal sphincter. Nhr-97 expression during development of C. elegans was determined by...
