MAP3K7CL Inhibits the Inflammatory Responses in Goose Fatty Liver.

Area of Science:

• Veterinary Science
• Molecular Biology
• Hepatology

Background:

• Inflammation is common in human liver disease but repressed in geese.
• Goose fatty liver disease pathogenesis remains incompletely understood.
• The role of MAP3K7CL in goose liver health requires investigation.

Purpose of the Study:

• To investigate the function of MAP3K7CL in goose fatty liver formation.
• To explore the relationship between MAP3K7CL and inflammatory pathways in geese.
• To analyze gene expression changes related to MAP3K7CL in goose hepatocytes.

Main Methods:

• Overfeeding model in healthy male geese (control vs. overfed groups).
• Transcriptome analysis of goose primary hepatocytes with MAP3K7CL overexpression.
• Lipopolysaccharide (LPS) treatment to induce inflammatory responses.

Main Results:

• MAP3K7CL mRNA expression was elevated in overfed geese livers.
• MAP3K7CL overexpression altered MAPK signaling pathway genes, downregulating DDIT3, IGF1R, NF1, PDGFB and upregulating HSPB1.
• MAP3K7CL overexpression reduced LPS-induced LITAF and caspase-3 expression; DDIT3 and LITAF were downregulated, while HSPB1 was upregulated in overfed geese.
• LPS decreased MAP3K7CL expression but increased LITAF and IL-6; co-overexpression of MAP3K7CL with LPS downregulated LITAF and IL-6.

Conclusions:

• MAP3K7CL plays a role in goose fatty liver development.
• MAP3K7CL may exert anti-inflammatory effects in goose fatty liver.
• MAP3K7CL influences key inflammatory and apoptotic genes in goose liver cells.
