The heat shock transcription factor HSF1 was recently demonstrated to play a key role in the development of tumors associated with activation of Ras or inactivation of p53. Here we show that HSF1 is required for cell transformation and tumorigenesis induced by HER2 oncogene responsible for aggressive breast tumors. Upon expression of HER2, untransformed(More)
Depletion of the major heat shock protein Hsp72 leads to activation of the senescence program in a variety of tumor cell lines via both p53-dependent and p53-independent pathways. Here, we found that the Hsp72-depleted cells show defect in phosphorylation and activation of the protein kinase Chk1 by genotoxic stresses, such as UVC irradiation or(More)
The major heat shock protein Hsp72 is expressed at elevated levels in many human cancers and its expression correlates with tumor progression. Here, we investigated the role of Hsp72 in Her2 oncogene-induced neoplastic transformation and tumorigenesis. Expression of Her2 in untransformed MCF10A mammary epithelial cells caused transformation, as judged by(More)
This paper presents a case study of a discrete event simulation model of an Accident and Emergency Unit in a hospital in the UK. The objective of the study is to create a simulation study of the A&E Unit, to evaluate alternative scenarios and hence reducing patient waiting time. The case study uses a novel approach to predict the arrival time of(More)
Reduced expression of the p53 family member p63 has been suggested to play a causative role in cancer metastasis. Here, we show that ΔNp63α, the predominant p63 isoform, plays a major role in regulation of cell migration, invasion and cancer metastasis. We identified mitogen-activated protein (MAP) kinase phosphatase 3 (MKP3) as a downstream target of(More)
