Disease Name: | Liver Cirrhosis |
Sample: | epatic stellate cell |
Dysfunction Pattern: | Interaction(hsa-miR-1291/LEFTY2 Axis) |
Validated Method: | Western Blot//qRT-PCR//PCR//Microarray//RNA Network |
Description: | For example, circCREBBP was significantly down-regulated in primary hepatic stellate cells (HSCs) and liver tissue of HF mice induced by CCl4 compared to those in the vehicle group. Mechanically, circCREBBP acts as a sponge for hsa-miR-1291 and subsequently promotes LEFTY2 expression. |
Causality: | Yes |
Causal Description: | Overexpression of circCREBBP with AAV8-circCREBBP in vivo prevented CCl4-induced HF worsening by reducing serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) contents, liver hydroxyproline levels, collagen deposition, and levels of pro-fibrosis genes and pro-inflammatory cytokines. Furthermore, in vitro function loss and function gain analysis showed that circCREBBP inhibited HSCs activation and proliferation. |
