Heading towards a dead end: the role of DND1 in germ line differentiation of human iPSCs

Project description:The DND microRNA-mediated repression inhibitor 1 (DND1) is a conserved RNA binding protein (RBP) and plays an important role in survival and maintenance of primordial germ cells (PGCs) and the development of the male germline in zebrafish and mice. It was shown to be expressed in human pluripotent stem cells (PSCs), PGCs, and spermatogonia, but little is known about its specific role in pluripotency and human germline development. Here we use CRISPR/Cas mediated knockout and PGC-like cell (PGCLC) differentiation in human iPSCs to analyse if DND1 (1) plays a role in maintaining pluripotency and (2) in specification of PGCLCs. We generated several clonal lines with biallelic loss of function mutations and analysed their potential to differentiate towards PGCLCs and their gene expression on RNA and protein level via bulk RNA sequencing and mass spectrometry. The generated knockout iPSCs showed no differences in pluripotency gene expression, proliferation nor trilineage differentiation potential, but yielded reduced numbers o PGCLCs compared to their parental iPSCs. RNAseq analysis in PGCLCs showed significantly reduced expression of genes associated with cellular developmental processes and cell differentiation in knockout cells, including known markers for PGCs (NANOS3, SOX17, PRDM1, EPCAM) and naïve pluripotency (TFCP2L, DNMT3L).

Transcriptome expression pattern of E11.5 PGCs, P2 GSCs, and CD49f+GSCs.

Project description:The cell identities of CD49f+GSCs were further identified by comparing them with the E11.5 PGCs and P2 GSCs. The transcriptomic analysis revealed that the CD49f+GSCs had 1/3 similar genes profile to the E11.5 PGCs and P2 GSCs. Further gene ontology (GO) analysis demonstrated that the E11.5 PGCs, P2 GSCs, and CD49f+GSCs shared the partial similar gene expression profile of pluripotency regulation signaling pathway, PI3K-AKT signaling, chemokine signaling, and HIF-1 signaling.

Transcriptome changes in leaves of the DEFENSE NO DEATH 1 (DND1) silenced potato plants

Project description:Silencing of DND1 in potato leads to resistance to late blight, powdery mildew and Botrytis cinerea. At the same time, however, it reduces plant growth and causes leaf necrosis. To get knowledge on the molecular events behind the pleiotropic effect of DND1 downregulation in potato transcriptome analysis were performed on three DND1 silenced lines in comparison with the potato cultivar ‘Désirée’ as a wild-type.

Transcriptome profiling of wild type primordial germ cells (PGC) by RNAseq

Project description:Purpose: To identify molecular pathways underlying epigenetic reprogramming in early germ cell precursors, we examined global gene expression of wild type primordial germ cells using mRNA sequencing. Methods: Given the limited number of PGCs collected from E9.5 to E13.5 (ranging from 300 to 5000), we used a low-input RNA sequencing method, Smart-Seq. RNA libraries were pooled and sequenced by Illumina Hiseq. Results: We generated >22 million uniquely mapped reads per sample and identified >10 thousand transcripts per genotype (RPKM>0.1). Hierarchical clustering and correlation analysis on gene expression indicates samples were clearly separated according to their genotypes with Spearman correlation coefficient of 0.98/0.99 within biological replicates. Compared with E9.5 PGCs, 479 genes were significantly up-regulated and 248 genes were down-regulated in E11.5 PGCs. When compared with E11.5 PGCs, male E13.5 PGCs had 362 up-regulated, and 239 down-regulated genes, whereas female E13.5 PGCs had 1163 up-regulated and 333 down-regulated genes. Overall, the number of up-regulated genes was greater than that of the down-regulated genes in every comparison, suggesting that gene expression is generally activated during PGC reprogramming. mRNA profiles of primordial germ cells derived from developmental embryos stages (E9.5, E11.5 and E13.5) were generated by deep sequencing, in duplicates (E9.5 and E11.5) or triplicates (E13.5f and E13.5m), using Illumina Hiseq.

Heading towards a dead end: the role of DND1 in germ line differentiation of human iPSCs

Project description:We knocked out DND1 in human iPSCs and analysed its role in pluripotency and differentiation. We showed that general pluripotency gene expression is not affected, but KO iPSCs differentiate less efficiently towards PGC-like cells and remaining PGCLCs show reduced expression of NANOS3 and PRDM1.

Proteome landscape of mouse primordial germ cells

Project description:Primordial germ cells (PGCs) are precursors of both male and female gametes as fundamental materials for organism development. The transcriptome, methylome and chromatin accessibility profiles of PGCs in both mice and humans have been recently reported. However, little is known about the characteristics of PGCs at the protein levels, which directly exert cellular functions. Here, we construct landscapes of both proteome of mouse PGCs at E11.5, E13.5 and E16.5 days, the three critical developmental windows for PGCs’ sex differentiation, female meiosis initiation and male mitotic arrest. In each developmental stage of PGCs nearly 2000-3000 proteins are identified, among which specific functional pathways such as oxidative phosphorylation, DNA damage repair, and meiotic cell cycle are involved for different events during PGCs development. Thus, our work offers a valuable resource for the systematic investigations of PGC development at protein level.
