RNA-seq Analysis of Mier1 Effects in HFD Aging and Adipose Tissue Lipe Knockout Mice after 70% Partial Hepatectomy


ABSTRACT: To explore how Mier1 affiects high-fat diet-fed, aging and adipose tissue Lipe knockout mice liver regeneration, we specifically knocked out liver Mier1 in high-fat diet-fed, aging and adipose tissue Lipe knockout mice through adeno-associated virus (AAV). The mice we used were knocked in a Cre-induced Cas9 expression cassette. Through tail vein injection, we delivered the AAV expressing Cre-recombinase under TBG promoter, and sgRNA targeting Mier1 (AAV-Mier1 sgRNA), into the adult Cas9 knockin mice to knock out the Mier1 gene in liver. AAV vectors with no sgRNA inserted (AAV-Cre) were used in control animals. To assess the role of MIER1 in liver regeneration, we performed 70% partial hepatectomy on high-fat diet-fed, aging and adipose tissue Lipe knockout mice. We then performed RNA sequencing analysis on liver tissues collected from control and Mier1 ko groups at 0 h, 48h or 36 h after partial hepatectomy. RNA-seq analysis showed that after partial hepatectomy, MIER1 loss caused significant upregulation of genes enriched in cell proliferation relevant pathways.
