SLC26A4-AS1 Agrava a Hipertrofia Cardíaca Induzida por AngII Aumentando a Expressão de SLC26A4

Abstract

FUNDAMENTO: Foi relatado que o RNA 1 antisenso 1 (SLC26A4-AS1) do membro 4 da família de transportadores de soluto 26 está altamente relacionado à hipertrofia cardíaca. OBJETIVO: Esta pesquisa visa investigar o papel e o mecanismo específicos de SLC26A4-AS1 na hipertrofia cardíaca, fornecendo um novo marcador para o tratamento da hipertrofia cardíaca. MÉTODOS: Angiotensina II (AngII) foi infundida em cardiomiócitos ventriculares (NMVCs) de camundongos neonatos para induzir hipertrofia cardíaca. A expressão gênica foi detectada por PCR quantitativo em tempo real (RT-qPCR). Os níveis de proteína foram avaliados por western blot. Ensaios funcionais analisaram o papel de SLC26A4-AS1. O mecanismo de SLC26A4-AS1 foi avaliado por imunoprecipitação de proteína de ligação a RNA (RIP), pull-down de RNA e ensaios de luciferase repórter. O valor de p < 0,05 foi identificado como significância estatística. O teste t de Student avaliou a comparação dos dois grupos. A diferença entre os diferentes grupos foi analisada por análise de variância (ANOVA) de uma via. RESULTADOS: SLC26A4-AS1 é regulado para cima em NMVCs tratados com AngII e promove hipertrofia cardíaca induzida por AngII. SLC26A4-AS1 regula o membro 4 da família de transportadores de soluto 26 (SLC26A4) por meio do funcionamento como um RNA endógeno competitivo (ceRNA) para modular o microRNA (miR)-301a-3p e o miR-301b-3p em NMVCs. SLC26A4-AS1 promove hipertrofia cardíaca induzida por AngII via regulação para cima de SLC26A4 ou absorção de miR-301a-3p/miR-301b-3p. CONCLUSÃO: SLC26A4-AS1 agrava a hipertrofia cardíaca induzida por AngII via absorção de miR-301a-3p ou miR-301b-3p para aumentar a expressão de SLC26A4.
