Description
TCL1 is an an oncogene and transgenic (Tg) mice expressing TCL1 specifically in B-cells are well-characterized models for chronic lymphocytic leukemia. On the contrary, PTPROt is a phosphatase with tumor suppressor characteristics in many cancers including leukemia. Our hypothesis was that transgenic expression of PTPROt in the B-cells of TCL1 Tg mice will alleviate disease phenotype and allow the study of the in vivo mechanism of action of PTPROt. To test this we have generated Tg mice with B-cell specific expression of PTPROt and crossed these mice with the TCL1 Tg mice.

Description
The euchromatin histone methyltransferase 2 (EHMT2, aka G9a) methylates histone H3K9 to repress gene expression, but it also acts as a coactivator for some nuclear receptors. The molecular mechanisms underlying this activation remain elusive. Here we show that G9a functions as a bona fide coactivator of the endogenous estrogen receptor a (ERa) in breast cancer cells in a histone methylation-independent manner. G9a dimethylates ERa protein at lysine 235 both in vitro and in cells. Dimethylation of ERaK235 (ERaK235me2) is recognized by the Tudor domain of PHF20, which in turn recruits the MOF histone acetyltransferase (HAT) complex to ERa target gene promoters to deposit histone H4K16 acetylation promoting active transcription. Together, our in vitro and in vivo data establish the molecular mechanism by which G9a functions as an ERa coactivator. Along with the PHF20/MOF complex, G9a links the crosstalk between ERa methylation and histone acetylation governing the epigenetic regulation of hormonal gene expression. Overall design: G9a KD RNA-seq and PHF20 KD RNA-seq with and without E2 treatment

Description
Non-syndromic cleft lip/palate (NSCL/P) is a complex, frequent congenital malformation, determined by the interplay between genetic and environmental factors during embryonic development. Previous findings have appointed an aetiological overlap between NSCL/P and cancer, and alterations in similar biological pathways may underpin both conditions. Here, using a combination of transcriptomic profiling and functional approaches, we report that NSCL/P dental pulp stem cells exhibit dysregulation of a co-expressed gene network mainly associated with DNA double-strand break repair and cell cycle control (p = 2.88x10-2 5.02x10-9). This network included important genes for these cellular processes, such as BRCA1, RAD51, and MSH2, which are predicted to be regulated by transcription factor E2F1. Functional assays support these findings, revealing that NSCL/P cells accumulate DNA double-strand breaks upon exposure to H2O2. Furthermore, we show that E2f1, Brca1 and Rad51 involved in DNA repair are co-expressed in the developing embryonic orofacial primordia, and may act as a molecular hub playing a role in lip and palate morphogenesis. In conclusion, we show that cellular defences against DNA damage may take part in the pathogenesis of NSCL/P, in accordance with the hypothesis of aetiological overlap between this malformation and cancer. These results provide more information regarding the aetiology of NSCL/P and have the potential tocan potentially assist incontribute to the development of future preventive strategies.

Description
Non-coding RNAs regulate many biological processes including neurogenesis. The brain-enriched miR-124 is assigned as a key player of neuronal differentiation via its complex, but little understood, regulation of thousands of annotated targets. To systematically chart its regulatory functions, we used CRISPR/Cas9 gene editing to disrupt all six miR-124 alleles in human stem cells. Upon neuronal induction, miR-124-depleted cells underwent neurogenesis and became functional neurons, albeit with altered morphology and neurotransmitter specification. By RNA-induced-silencing-complex precipitation, we found that other miRNA species were upregulated in miR-124 depleted neurons. Furthermore, we identified 98 miR-124 targets of which some directly led to decreased viability. We performed advanced transcription-factor-network analysis and revealed indirect miR-124 effects on apoptosis and neuronal subtype differentiation. Our data emphasizes the need for combined experimental- and systems-level analyses to comprehensively disentangle and reveal miRNA functions, including their involvement in the neurogenesis of diverse neuronal cell types found in the human brain. Overall design: RNA profile for timecourse of neuronal Neurogenin-1 and 2-triggered differentiation from human iPSCs (wildtype and ?miR-124).
