P27 knockout mice viable
WebMar 13, 2007 · Conventional p27 knockout mice exhibit a 70% increase in the number of cerebellar granule cells ( 14 ). However, LOH naturally occurs in sporadic cells rather than throughout entire tissues. Moreover, conventional knockout precludes analysis of the cell autonomy of gene function. WebFigure 1. The p27→p57 knock-in mouse. (A) Structures of p27 and p57. The two proteins share CKI and QT domains at their NH 2 - and COOH-termini, respectively, whereas p57 harbors a unique central domain that is not conserved between human and mouse. (B and C) Phenotypic normalization of p57 knockout mice by knock-in of the p27 gene.

WebMar 10, 2009 · Although p27 and p57 are structurally related cyclin-dependent kinase inhibitors (CKIs), and are thought to perform similar functions, p27 knockout (p27 KO) and p57 KO mice show distinct phenotypes. To elucidate the in vivo functions of these CKIs, we have now generated a knock-in mouse model (p57 p27KI), in which the p57 gene has been … http://genesdev.cshlp.org/content/18/21/2602.full.html
WebConsistent with its role as a negative regu- lator of cell proliferation, p27 knockout mice are about 25% larger than wild-type littermates (3–5). Most organs of p27 knockout mice have postmitotic and properly dif- ferentiated cells in greater numbers. The phenotypes of cells cultured from p27 knockout mice are cell-type spe- cific.

WebThe p57p²⁷KI mice are viable and appear healthy, with most of the developmental defects characteristic of p57KO mice having been corrected by p27 knock-in. Such developmental defects of p57KO mice were also ameliorated in mice deficient in both p57 and the transcription factor E2F1, suggesting that loss of p57 promotes E2F1-dependent apoptosis.
