DGCR8 haploinsufficiency leads to primate-specific RNA dysregulation and pluripotency defects

Project description:The 22q11.2 deletion syndrome (22qDS) is caused by a microdeletion in one of the chromosomes 22, comprising around 40 genes and including DGCR8, an essential gene for miRNA biogenesis and transposable elements control. Most of the clinical manifestations of 22qDS have their origin during embryonic development, but the contribution of human DGCR8 hemizygosity to the disease is unknown. To clarify the overall effect of DGCR8 in the context of 22qDS, we have generated two human embryonic models of DGCR8 +/-.In this dataset we use small RNA-seq to study the effect of DGCR8 heterozygosity on steady state miRNA levels in human embryonic stem cells.

Stabilizing Heterochromatin by DGCR8 Alleviates Senescence and Osteoarthritis

Project description:DiGeorge syndrome critical region 8 (DGCR8) is a critical component of the canonical microprocessor complex for microRNA biogenesis. However, the non-canonical functions of DGCR8 have not been studied. Here, we demonstrate that DGCR8 plays an important role in maintaining heterochromatin organization and attenuating aging. An N-terminal-truncated version of DGCR8 (DR8dex2) accelerated senescence in human mesenchymal stem cells (hMSCs) independent of its miRNA-processing activity, which is mediated by its C-terminal domains. Further studies revealed that DGCR8 maintained heterochromatin organization by interacting with the nuclear envelope protein Lamin B1, and heterochromatin-associated proteins, KAP1 and HP1 Overexpression of any of these proteins, including DGCR8, reversed premature senescent phenotypes in DR8dex2 hMSCs. Finally, DGCR8 was downregulated in pathologically and naturally aged hMSCs, whereas DGCR8 overexpression alleviated hMSC aging and osteoarthritis in mice. Taken together, these analyses uncovered a novel, miRNA processing-independent role for DGCR8 in maintaining heterochromatin organization and attenuating senescence. DGCR8 may therefore represent a new therapeutic target for alleviating human aging-related disorders.

Haploinsufficiency of the mouse Tshz3 gene leads to kidney dysfunction

Project description:Renal tract defects and autism spectrum disorder (ASD) deficits represent the phenotypic core of the 19q12 deletion syndrome caused by the loss of one copy of the TSHZ3 gene. While a proportion of Tshz3 heterozygous (Tshz3+/lacZ) mice display ureteral defects, no kidney defects have been reported in these mice. The purpose of this study was to characterize the expression of Tshz3 in adult kidney as well as the renal physiological consequences of embryonic haploinsufficiency of Tshz3 by analyzing the morphology and function of Tshz3 heterozygous adult kidney. Here, we described Tshz3 expression in the smooth muscle and stromal cells lining the renal pelvis, the papilla and glomerular endothelial cells (GEnCs) of the adult kidney. Histological analysis showed that Tshz3+/lacZ adult kidney had an average of 29% fewer glomeruli than wild type kidney. Transmission electron microscopy (TEM) of Tshz3+/lacZ glomeruli revealed ultrastructural defects. Compared to wild type, Tshz3+/lacZ mice showed no difference in their urine parameters but lower blood urea, phosphates, magnesium and potassium at 2 months of age. At the molecular level, transcriptome analysis identified differentially expressed genes related to inflammatory processes in Tshz3+/lacZ compare to wild type (WT; control) adult kidneys. Lastly, analysis of the urinary peptidome revealed 33 peptides associated with Tshz3+/lacZ adult mice. These results provide the first evidence that in the mouse Tshz3 haploinsufficiency leads to cellular, molecular and functional abnormalities in the adult mouse kidney.

Prkar1a haploinsufficiency leads to an overall increase in tumors caused by other genetic defects or chemical induction

Project description:[original title] Prkar1a haploinsufficiency in mice leads to an overall increase in tumors caused by other genetic defects or chemical induction We investigated the Prkar1a+/- mice when bred within the Rb1+/- or Trp53+/- genetic backgrounds, or treated with a 2-step skin carcinogenesis protocol. Prkar1a+/-Trp53+/- mice developed more bone sarcomas than Trp53+/- mice (p<0.05) and Prkar1a+/-Rb1+/- mice grew more and larger pituitary and thyroid tumors than Rb1+/- mice. All mice with double heterozygosity had significantly reduced life-spans compared with their single-heterozygous counterparts. Finally, Prkar1a+/- mice developed more papillomas than wild-type animals when treated with a 2-step skin carcinogenesis protocol. A whole-genome transcriptome profiling of tumors produced by all three models identified Wnt signaling as the main pathway activated by abnormal cAMP signaling in these tissues, along with (expected) cell cycle gene abnormalities, all confirmed by qRT-PCR array and immunohistochemical analyses.
