Lack of inactivation of a mouse X-linked gene physically separated from the inactivation centre.
Previous evidence had shown that, when a mammalian X-chromosome is broken by a translocation, only one of the two X-chromosome segments shows cytological signs of X-inactivation in the form of late replication or Kanda staining. In the two mouse X-autosome translocations T(X;4)37H and T(X;11)38H the X-chromosome break is in the A1-A2 bands; in both, the shorter translocation product fails to ex...
متن کاملX-linked genes in female embryonic stem cells carry an epigenetic mark prior to the onset of X inactivation.
We use chromatin immunoprecipitation to show that genes on the two active X chromosomes in undifferentiated, XX female embryonic stem cells (ES cells) are marked by hyperacetylation of all core histones, hyper(di)methylation of H3 lysine 4 and hypo(di)methylation of H3 lysine 9, compared with autosomal genes or genes on the single active X in XY male cells. The mark is found on both coding and ...
متن کاملX-inactivation modifies disease severity in female carriers of murine X-linked Alport syndrome.
BACKGROUND Female carriers of X-linked Alport syndrome (XLAS) demonstrate variability in clinical phenotype that, unlike males, cannot be correlated with genotype. X-inactivation, the method by which females (XX) silence transcription from one X chromosome in order to achieve gene dosage parity with males (XY), likely modifies the carrier phenotype, but this hypothesis has not been tested direc...
متن کاملIntegrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis
Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
متن کاملPrenatal sex determination in suspicious cases of X-linked recessive diseases by the amelogenin gene
Objective(s):To determine the fetal discernment in suspected cases of sex linked recessive disease in the first trimester of pregnancy. Materials and Methods: After collection of 100 Chorionic Villi samples, the DNAs were extracted and baby gender was determined. Meanwhile, after increasing the sensitivity, the system was able to detect the sex of each cell which was obtained by biopsy. Resul...
