Abstract:

PTH 1-34 has an osteogenic effect on antler MSCs.The study aimed to explore the possible mechanism of PTH 1-34 promoting osteogenesis in antler MSCs by using the high-throughput non-reference transcriptome sequencing method.The 3rd generation antler MSCs were randomly divided into three groups(control group,induction group,and PTH 1-34 intervention group)with three replicates each.After the identification of markers and calcium nodules,total RNA was extracted using the TRIzol method and these libraries were double-end sequenced using Next-Generation Sequencing,an Illumina-based sequencing platform.Addition of 10 nmol/L PTH 1-34 for osteogenesis induction significantly increased alkaline phosphatase activity and calcium nodule production in antler mesenchymal stem cells.The non-reference transcriptome sequencing was selected due to less than 50% efficiency of gene sequence comparison with deer family published by NCBI.Through differential gene enrichment analysis,a total of 5 737 differentially expressed genes were screened,of which 1 877 were up-regulated and 3 860 were down-regulated;GO enrichment analysis showed that the types of differential genes mainly included cell motility,proliferation and migration,bone development,angiogenesis and morphogenesis related under the action of biological processes;through screening,eight genes related to osteogenesis were found:RUNX2,BGN,ALPL,SPARC,OPN,CPNE1,STRN4,VAPB;two genes related to cellular autophagy:WiPi2,ATG14;four genes related to angiogenesis:UNC5B,SHC1,FLNA,TNFSF15,which were validated using qRT-PCR method,and the results were consistent with the sequencing results;transcription factors with high predicted correlation family was zf-C2H2,and the osteogenic transcription factor SP7 was screened.PTH 1-34 could promote osteogenic differentiation of antler mesenchymal stem cells by upregulating the mRNA expression of RUNX2,SP7,BGN,ALPL,SPARC,OPN,CPNE1,STRN4,VAPB;possibly regulating angiogenesis and cellular autophagy by inhibiting the process of antler ossification.
