Project description:Colorectal cancer (CRC) has become a predominant cancer worldwide. In order to understand the process of carcinogenesis, an shRNA library screening is employed for searching candidate genes that promote proliferation in the CRC cell line HT29. The candidate genes overlapped with differentially expressed genes in 32 CRC tumor tissues in the GEO dataset GSE8671. The seventh-ranked TEX10 is upregulated in CRC and its knockdown decreased cell proliferation. The TEX10 high-expression group exhibits worse overall survival (P = 0.003) and progression-free survival (P < 0.001) than the TEX10 low-expression group. TEX10 depletion decreases the growth of CRC cells in vitro and in vivo. GSEA indicates that the NF-κB pathway is significantly enriched in the genes downregulated by TEX10 knockdown. Mechanistically, TEX10 interacts with p65 and increases its nuclear localization. TEX10 promotes p65 occupancy at gene promoters and regulates the expression of a subset of p65-targeted genes including TNFAIP8, SAT1 and IL6ST. Taken together, this study identifies that TEX10 promotes the proliferation of CRC cells in a p65-dependent manner. In addition, high TEX10 expression is associated with poor prognosis in CRC patients.

Project description:To systematically investigate the expression patterns of all potential niche factors in testis, we performed single-cell RNA sequencing (scRNA-seq) of all testicular somatic cell types. To enrich somatic cells, we depleted Tomato+ cells from the testes of 2-month-old Ddx4-creER; R26tdTomato mice at 4 weeks after tamoxifen treatment. Then the cells were further captured with 10x Genomics platform. After analysis of the integrated data, we mapped the expression patterns of all known niche factors in testicular somatic cells. We also performed scRNA-seq of testicular cells from 6-week-old control and Amh-cre;Scf fl/fl mice to study the effect of Scf conditional knockout from Sertoli cells on spermatogenesis. By scRNA-seq data analysis, we found that conditional knockout of Scf from Sertoli cells blocks spermatogenesis by depleting differentiating spermatogonia

Project description:Post-transcriptional regulation mediated by RNA binding proteins is crucial for male germline development. Insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1), an RNA binding protein, is specifically expressed in human and mouse male gonads and is involved in manifold biological processes and tumorigenesis. However, the function of IGF2BP1 in mammalian spermatogenesis remains poorly understood. Herein, we generated an Igf2bp1 conditional knockout mouse model using Nanos3-Cre. Germ cell deficiency of Igf2bp1 in mice caused spermatogenic defects in an age-dependent manner, resulting in decreased numbers of undifferentiated spermatogonia and increased germ cell apoptosis. Immunoprecipitation-mass spectrometry analysis revealed that ELAV-like RNA binding protein 1, a well-recognized mRNA stabilizer, interacted with IGF2BP1. Single cell RNA-sequencing showed distinct mRNA profiles in spermatogonia from conditional knockout versus wide type mice. Further research showed that IGF2BP1 plays a vital role in the modulation of spermatogenesis by regulating Lin28a mRNA, which is essential for clonal expansion of undifferentiated spermatogonia. Thus, our results highlight the crucial effects of IGF2BP1 on spermatogonia for the long-term maintenance of spermatogenesis

Project description:Super-enhancers (SEs) are large clusters of transcriptional enhancers that are co-occupied by multiple lineage specific transcription factors driving expression of genes that define cell identity. In embryonic stem cells (ESCs), SEs are highly enriched for Oct4, Sox2, and Nanog in the enhanceosome assembly and express enhancer RNAs (eRNAs). We sought to dissect the molecular control mechanism of SE activity and eRNA transcription for pluripotency and reprogramming. Starting from a protein interaction network surrounding Sox2, a key pluripotency and reprogramming factor that guides the ESC-specific enhanceosome assembly and orchestrates the hierarchical transcriptional activation during the final stage of reprogramming, we discovered Tex10 as a novel pluripotency factor that is evolutionally conserved and functionally significant in ESC self-renewal, early embryo development, and reprogramming. Tex10 is enriched at SEs in a Sox2-dependent manner and coordinates histone acetylation and DNA demethylation of SEs. Our study sheds new light on epigenetic control of SE activity for cell fate determination. Genome binding/occupancy profiling of Tex10 was performed in mouse embryonic stem cells by ChIP sequencing.
