ABSTRACT
OBJECTIVE:
To identify immune-related gene expression profiles of adipocytes under low temperatures with RNA sequencing as a model for Bell's palsy implications.METHODS:
Adipocytes were harvested from the white adipose tissue of male Sprague-Dawley rats and cultured under different acute-grade cold exposure conditions of 30, 20, and 10°C, and their genomes were sequenced for RNA sequencing analysis. The differentially expressed genes (DEGs) were validated with reverse transcription polymerase chain reaction.RESULTS:
In total, 55 (35 upregulated and 20 downregulated), 121 (76 upregulated and 45 downregulated), and 92 (64 upregulated and 28 downregulated) DEGs were identified under 30, 20, and 10°C compared with the control, respectively. KEGG and GO analysis revealed that the DEGs were considerably enriched in immune-related pathways (leukocyte transendothelial migration and platelet activation) and infection (bacterial invasion of epithelial cells and Salmonella infection). The levels of key inflammatory chemokines (CSF1, CXCL1, CCL2, and CCL7) were enhanced after cold exposure.CONCLUSION:
These findings broaden our understanding of the immune responses to cold exposure in adipocytes. The molecular profiles of adipocyte immune function will help clarify the potential mechanism impacting myelin, which might contribute to the development of strategies to control Bell's palsy.Palavras-chave
