BACKGROUND Observations that diabetics treated with biguanide drugs have a reduced risk of developing cancer have prompted an enthusiasm for these agents as anti-cancer therapies. We sought to determine the efficacy of the biguanide phenformin in the chemoprophylaxis and in the treatment of oestrogen receptor (ER)-positive MCF7 and receptor triple-negative(More)
The human oesophageal epithelium is subject to damage from thermal stresses and low extracellular pH that can play a role in the cancer progression sequence, thus identifying a physiological model system that can be used to determine how stress responses control carcinogenesis. The classic heat shock protein HSP70 is not induced but rather is down-regulated(More)
A new cancer gene, HIC-1 (Hypermethylated in Cancer) telomeric to p53 on chromosome 17p may be of clinical importance in sporadic breast cancer. Regional DNA hypermethylation of 17p13.3 resulting in suppression of gene expression has been shown to precede 17p structural changes in human carcinogenesis. In addition, loss of heterozygosity studies have(More)
Fine needle aspiration (FNA) biopsy is the least invasive method of sampling breast cancer in vivo and provides material for breast cancer diagnosis. FNA has also been used to examine cellular markers to predict and monitor the effects of therapy. The aim of this study was to assess the accuracy of using FNA material compared with resected cancer for(More)
