GenomePixelizer is a visualization tool that generates custom images of the physical or genetic positions of specified sets of genes in whole genomes or parts of genomes. Multiple sets of genes can be shown simultaneously with user-defined characteristics displayed. It allows the analysis of duplication events within and between species based on sequence(More)
Cells undergoing oncogenic transformation frequently inactivate tumor suppressor pathways that could prevent their uncontrolled growth. Among those pathways p53 and p38MAPK pathways play a critical role in regulation of cell cycle, senescence and cell death in response to activation of oncogenes, stress and DNA damage. Consequently, these two pathways are(More)
UV irradiation is a major natural and artificial stress factor that may cause severe skin injury. UV irradiation induces DNA damage, which, eventually, may lead to cell death, senescence or oncogenic mutations and tumor growth. Wip1 is a phosphatase involved in the regulation of DNA damage response and oncogenic stress. Here, we studied response to UV-B(More)
Inactivation of p53 found in more than half of human cancers is often associated with increased tumor resistance to anti-cancer therapy. We have previously shown that overexpression of the phosphatase Wip1 in p53-negative tumors sensitizes them to chemotherapeutic agents, while protecting normal tissues from the side effects of anti-cancer treatment. In(More)
A key regulator of cellular senescence, mTORC1 complex, is a target of many signaling cascades, including Ras/Raf/MEK/ERK cascade. In this paper, we investigated the role of the MEK/ERK branch of this cascade in the process of cellular senescence induced by sodium butyrate (NaBut), a histone deacetylase inhibitor (HDACI), in transformed rat-embryo(More)
We have studied the role of the stress kinases p38 and JNK1,2 in premature senescence induced by sodium butyrate (NaBut), a histone deacetylase inhibitor, in mouse embryonic fibroblasts transformed by E1A+cHa-Ras oncogenes. It was found that transformants from p38 knockout cells are able to implement NaBut-induced senescence exhibited by cell cycle arrest,(More)
