Efeitos antiinflamatórios e antiproliferativos dos glicocorticóides: concordância ou discordância?

Abstract: A AÇÃO DOS GLICOCORTICÓIDES (GC) é mediada por um receptor protéico intracelular, o receptor de GC (RG), que pertence à superfamília dos receptores nucleares e age como um fator de transcrição ativado pelo hormônio, regulando a expressão dos genes responsivos aos GC. O gene do RG humano (GenBank NR3C1) encontra-se na porção distal do cromossomo 5, sendo composto por 9 éxons. Várias isoformas do receptor são produzidas por splicing alternativo de um único gene (1,2). A isoforma α, a forma clássica do RG, é o me… Show more

“…Only a small fraction (6%) exists as a free hormone, and passes through cell membranes binding to specific plasma receptors. 10 The hormone-receptor complex enters the nucleus where it will stimulate, suppress or influence the process of protein synthesis by means of interaction with DNA (genomic action) or with proteins involved in the transcription process (non-genomic action). 8,11 A third mechanism which was not dependent on intra-nuclear action could explain the rapid action of some corticosteroids, which supports their use for pulse therapy.…”
