Perilipin 1 (PLIN1) is a protein encoded by the gene in eukaryotes. PLIN1 is a member of the PAT protein family, a family of proteins related to lipid droplet (LD) surface proteins. PLIN1 phosphorylation plays a vital role during fat metabolism of adipose tissue lipolysis and fat storage in adipocytes. However, to further explore the regulation of the gene on the proliferation, differentiation and lipid metabolism of bovine adipocytes. In this study, the mRNA expression of at day six, was the highest during bovine adipocyte differentiation. Moreover, can promote the proliferation and differentiation of preadipocytes in cattle. On the sixth day, after transfection with, and overexpression of, the gene in bovine preadipocytes via adenovirus, cell samples were collected, and transcriptome sequencing was performed. A total of 1923 differentially expressed genes were detected. Through GO and KEGG pathway analysis, the differentially expressed genes were established to be mainly enriched in the AMPK, Wnt, and PPAR signaling pathways related to fat proliferation and differentiation. In conclusion, at the transcriptional level, plays an important role in regulating fat proliferation and metabolism. Additionally, the sequencing results screened new differentially expressed genes related to fat metabolism, providing theoretical support for molecular breeding of Qinchuan beef cattle.
perilipin 1(PLIN1)是真核生物中由该基因编码的一种蛋白质。PLIN1是PAT蛋白家族的成员,该家族是一类与脂滴(LD)表面蛋白相关的蛋白质。PLIN1磷酸化在脂肪组织脂解的脂肪代谢和脂肪细胞中的脂肪储存过程中起着至关重要的作用。然而,为了进一步探究该基因对牛脂肪细胞增殖、分化和脂质代谢的调控作用。在本研究中,在牛脂肪细胞分化过程中,第6天的mRNA表达量最高。此外,该基因可以促进牛前体脂肪细胞的增殖和分化。在第6天,通过腺病毒将该基因转染到牛前体脂肪细胞中并使其过表达后,收集细胞样本并进行转录组测序。共检测到1923个差异表达基因。通过GO和KEGG通路分析,确定差异表达基因主要富集在与脂肪增殖和分化相关的AMPK、Wnt和PPAR信号通路中。总之,在转录水平上,该基因在调节脂肪增殖和代谢中起重要作用。此外,测序结果筛选出了与脂肪代谢相关的新的差异表达基因,为秦川肉牛的分子育种提供了理论支持。
