- Abstract
Aim: Vitamin D
3 has been implicated in multiple reproductive events, whereas the effect of its bioactive metabolite 1α, 25 dihydroxyvitamin D3 (1,25(OH)2 D3 ) on transcriptome profile of the placenta is unclear. The aim of this article is to determine transcriptome-wide profile caused by 1,25(OH)2 D3 in human placental trophoblast cells., Methods: We performed RNA sequencing after stimulation of HTR-8/SVneo cells with 0.1, 1, 10, and 100 nM 1,25(OH)2 D3 for 24 h, identified differentially expressed genes by edgeR package (version 3.38.4), and analyzed Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways by webtool Metascape. Also, common genes and specific genes in different concentrations of 1,25(OH)2 D3 were identified., Results: There were 180, 158, 161, and 174 differentially expressed genes after 0.1, 1, 10, and 100 nM 1,25(OH)2 D3 stimulation, respectively. KEGG pathway analysis displayed that "lipid and atherosclerosis" were significantly enriched at 0.1 and 1 nM 1,25(OH)2 D3 , while "cytokine-cytokine receptor interaction," "TGF-beta signaling pathway" and "hippo signaling pathway" were significantly enriched in 1, 10, and 100 nM 1,25(OH)2 D3 . CYP24A1 was a significantly expressed common gene. UCP3 was significantly expressed in low concentrations and might affect energy metabolism. TCF24, EIF3CL, ABCD2, EPHA7, CRLF1, and SECTM1 were specific genes at physiological concentration. Similarly, SPDYE1, IQUB, IL18R1, and ZNF713 were considered as specific genes at supraphysiological concentration., Conclusions: 1,25(OH)2 D3 mainly affected the expression of CYP24A1 gene in HTR-8/SVneo cells. Specific genes accounted for the majority of differentially expressed genes at different concentrations. However, their functions need to be further confirmed., (© 2023 Japan Society of Obstetrics and Gynecology.)- Published
