Description
The ability of male reproduction is seriously dependent on Sertoli cells. However, the mechanisms governing the functional integrity of Sertoli cells remained largely unexplored. Tyrosine phosphatase protein Shp2 is expressed in germ, Leydig and Sertoli cells of mice testes. But the physiological role of Shp2 in the spermatogenesis was not fully understood. Thus, we conditionally deleted Shp2 gene in Sertoli cells using two transgenic models, and demonstrated that Shp2 deficiency caused infertility, excessive differentiation of SSCs and abnormal BTB in mice. To further discover the underlying mechanism of Shp2 regulation, we collected the mRNA of testes from wild type or knockout mice at 16.5 fetal day, Postnatal 3 days, 1 weeks, 2 weeks, and then screened the gene expression.

Description
Haploid stem cells offer an easy-to-manipulate genetic system and therefore have great values for studies of recessive phenotypes. Here, we show that mouse androgenetic haploid ES (ahES) cell lines can be established by transferring sperm into enucleated oocyte. The ahES cells maintain haploidy and stable growth over 30 passages, express pluripotent markers, possess the ability to differentiate into all three germ-layers in vitro and in vivo, and contribute to germline of chimeras when injected into blastocysts. Although epigenetically distinct from sperm cells, the ahES cells can produce viable and fertile progenies after intracytoplasmic injection into mature oocytes. The oocyte injection procedure can also produce viable transgenic mice from genetically engineered ahES cells.

Description
Haploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

Description
Regulatory T cells (Tregs) are a barrier to effective anti-tumor immunity. Neuropilin-1 (Nrp1) is required to maintain intratumoral Treg stability and function but is dispensable for peripheral immune homeostasis, Treg-restricted Nrp1 deletion in mice results in profound tumor resistant due to Treg functional fragility. Drivers of Treg fragility, the mechanistic basis of Nrp1 dependency, and the relevance of these processes for human cancer and immunotherapy remain unknown. NRP1 expression on human Tregs in melanoma and HNSCC was highly heterogeneous and correlated with prognosis. Using a mouse model of melanoma in which mutant Nrp1-deficient (Nrp1–/–) and wild type (WT) Tregs could be assessed in a competitive environment, we found that a high proportion of intratumoral Nrp1–/– Tregs produce interferon-? (IFN?), which in turn drove the fragility of surrounding WT Tregs, boosting anti-tumor immunity and facilitating tumor clearance. We also show that IFN?-induced Treg fragility is required for an effective response to PD1 immunotherapy, suggesting that cancer therapies promoting Treg fragility may be efficacious . Overall design: Tregs from B16 tumors and non-draining lymph nodes NDLN from WT, Nrp-1 deficient homozygous and heterozygous mice

Description
The goal of this study was to investigate the role of intragenic CTCF in alternative pre-mRNA splicing through a combined CTCF-ChIP-seq and RNA-seq approach. CTCF depletion led to decreased inclusion of weak upstream exons. Overall design: CTCF ChIP-seq was performed in BJAB and BL41 B cell lines and normalized relative to Rabbit Ig control IP-seq reads. RNA-seq was performed in BJAB and BL41 cells transduced with shRNA against CTCF or RFP as a control, and in untransduced cells as well.
