ABSTRACT: Purpose: Necroptosis as been implicated in various deseases. The goal of this study is to invastigate the impact of RIPK3 and MLKL in the lipid metabolism of adipocytes. Methods: 3T3-L1 preadipocytes invalidated or not for RIPK3 or MLKL were exposed differenciated into mature adipocytes and the mRNA profiles of wild type (WT), RIPK3-/- knockout (RIPK3-KO) or MLKL-/- knockout 3T3-L1 cells control (J0) or differenciated into mature adipocytes (J7) were generated by deep sequencing, in 3 copies, using Illumina NOVAseq 6000 plateform. Differential expression analysis between two conditions/groups (five biological replicates per condition) was performed using DESeq2 R package. Genes with an adjusted P value < 0.05 found by DESeq2 were assigned as differentially expressed. qRT–PCR validation was performed using SYBR Green assays Results: The DEGs were clustered using a hierarchical clustering algorithm, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis unveiled a clear reduction in the expression of genes involved in the early or late stages of adipogenesis in MLKL-KO cells Conclusions: Taken together, these data suggest that Mlkl but not Ripk3 deficiency impaired adipogenesis of 3T3-L1 cells by reducing the expression of pro-adipogenic factors and genes involved in fatty acid metabolism.
