RNA-seq Analysis of Fat Tissue Before and After Grafting in Mice

Purpose: To investigate the influence of grafting on adipose tissues, samples were collected from the inguinal fat tissues of mice before grafting and 1 week after grafting. Methods: The RNA-seq analysis was performed by Novogene (Beijing, China). Total RNA was drawn from the tissues with TRIzol reagent (Absin, Shanghai, China). Transcriptome sequencing were performed by using the Illumina HiSeq X Ten (Novogene Bioinformatics Technology Co., Ltd., Beijing, China). Mapping of 150-bp paired-end reads to the genes was undertaken. Result: In fat tissues one week after grafting, 28145 genes were detected. And 3271 genes were found to be upregulated, while 3745 genes were downregulated (padj < 0.05 and log2(FC) > 1), when compared with that in the natural fat tissues. Conclusions: Our study firstly reported the differentially expressed genes in adipose tissues after grafting, providind a valuable reference for fat grafting studies. RNA was extracted from the fat tissues before grafting and 1 week after fat grafting in mice for RNA-seq analysis (3 biological replicates per group).
