ABSTRACT
Recent studies in diverse organisms implicate proto-oncogenic pathways, including insulin-like growth factor-I (IGF-I), Ras and AKT/protein kinase B in the ageing process. Although IGF-I is thought to contribute to cancer by promoting growth and preventing apoptosis, evidence from model organisms suggests that proto-oncogene homologues might contribute to the DNA mutations and chromosomal damage that are observed in tumour cells by increasing DNA damage, in both dividing and non-dividing cells, and involving error-prone systems in DNA repair. This raises the possibility that cancer can be reduced by chronic downregulation of pro-ageing pathways.

    Faithful repair of DNA double-strand breaks (DSBs) is vital for animal development, as inappropriate repair can cause gross chromosomal alterations that result in cellular dysfunction, ultimately leading to cancer, or cell death. Correct processing of DSBs is not only essential for maintaining...

    Overexpression of the epidermal growth factor receptor (EGFR) is a hallmark of head and neck cancers and confers increased resistance and inferior survival rates. Despite targeted agents against EGFR, such as cetuximab (C225), almost half of treated patients fail this therapy, necessitating...

    The last few years have seen a significant increase in our understanding of the molecular pathways governing cell function in cancer. This has led to an explosive interest in novel molecularly-targeted agents and, until recently, the focus of research effort has been to combine these agents with...

    Purpose: Activation of the epidermal growth factor (EGF) receptor has previously been shown to increase the sensitivity of cancer cells to DNA-damaging agents, including cisplatin, UV-B, and γ-radiation. We now investigated the mechanisms by which EGF enhances the sensitivity of human ovarian...
