Small marker X chromosomes lack the X inactivation center

Witrynaimprinting, with exclusive inactivation of the paternal X chromosome (Xp) (3, 4). This seems to be due to an imprint on the maternal X chromosome (Xm) to remain active, as well as a paternal imprint to inactivate (5). By the third wave of differentiation, in epiblast cells derived from the inner cell mass (ICM), X inactivation is random ... WitrynaThe fragile site appears to have equal chances of being detected when located either on the early- or on the late-replicating X, which leads to the conclusion that the frequency of the fragile site is a consequence of the proportion of cells with the active Martin-Bell syndrome (MBS) gene and not the result of a better visualization of the site on … Witryna15 cze 2001 · Imprinted Xist expression is considered the exclusive cause of non-random inactivation of X P in the trophectoderm ( 29 ). The preferential inactivation of X P is due either to the resistance of X M to inactivation or a predisposition of X P to inactivation. A recent finding made by Tada et al. ( 44) favors the former possibility. pop up background
