P21 as a transcriptional co-represor of S-phase and mitotic control genes-kp21

ABSTRACT: Our goal is to find new genes regulated by p21 in human primary cells . To get it we carried out a gene expression profiling in two different models, human myeloid leukemia K562 cells and human keratinocytes both of them with conditional expression of p21. In order to find genes regulated by p21 in human primary cells we carried out a gene expression profiling in human myeloid leukemia K562 cells with conditional expression of p21. We previously described a K562 derivative, termed Kp21-4, that carries a zinc-inducible p21 gene (Munoz-Alonso MJ et at., 2005). We performed a kinetic study to identify the expression peak of p21 in this system. This transient induction of p21 was accompanied by proliferation arrest and an increase in polyploid cells after 48-72 h (Munoz-Alonso MJ et at., 2
