摘要:

为探究维生素C对小鼠TM4支持细胞的功能和基因表达影响,采用0、100、250和500 μmol·L-1的L-抗坏血酸2-磷酸倍半镁水合盐 (L-ascorbic acid 2-phosphate magnesium,AA2P)处理小鼠TM4支持细胞不同时间,分析不同AA2P处理水平和处理时间下的细胞活力;进一步采用多种研究方法检测细胞的增殖、凋亡、活性氧(reactive oxygen species,ROS)水平、线粒体功能、RNA甲基化(m6A)和组蛋白H3三甲基化(H3K4me3、H3K9me3和H3K36me3)水平、抗苗勒氏管激素(anti-Müllerian hormone,AMH)、雌二醇、乳酸以及基因表达的变化。结果表明,采用250 μmol·L-1 AA2P处理TM4细胞36 h能显著提高细胞活力,促进细胞增殖,降低细胞早期凋亡和活性氧水平,增强线粒体功能,改变m6A水平和组蛋白H3三甲基化(H3K4me3、H3K9me3和H3K36me3)水平,促进AMH和雌二醇的分泌,降低乳酸水平。RNA-seq检测结果显示,250 μmol·L-1 AA2P处理TM4细胞36 h诱导112个基因表达出现显著差异。GO(gene ontology)和KEGG(Kyoto encyclopedia of genes and genomes)富集到多条通路。综上表明,维生素C可调节小鼠TM4支持细胞的功能和基因表达。

Abstract:

To investigate the effects of vitamin C on the function and gene expression of mouse TM4 Sertoli cells, the cells were treated with 0, 100, 250 and 500 μmol·L-1 of L-ascorbic acid 2-phosphate magnesium hydrate (AA2P) for different time length. Cell viability under different treatments was used to select the optimal conditions for AA2P treatment of TM4 cells. Further, different methods were used to detect cell proliferation, apoptosis, reactive oxygen species (ROS) level, mitochondrial function, RNA methylation (m6A), histone H3 trimethylation levels (H3K4me3, H3K9me3 and H3K36me3), anti-Müllerian hormone (AMH), estradiol, lactate, as well as gene expression alteration. The results showed that treatment of TM4 cells with 250 μmol·L-1 AA2P for 36 h significantly increased cell viability, promoted cell proliferation, reduced early apoptosis, decreased ROS level, enhanced mitochondrial function, altered m6A level and histone H3 trimethylation (H3K4me3, H3K9me3 and H3K36me3) levels, promoted the secretion of AMH and estradiol, and reduced lactate level. RNA-seq results revealed that AA2P treatment (250 μmol·L-1, 36 h) induced significant differential expression of 112 genes, which were involving in multiple GO (gene ontology) items and KEGG (kyoto encyclopedia of genes and genomes) pathways. To sum up, vitamin C could regulate the function and gene expression of mouse TM4 Sertoli cells.
