A panel of 73 samples, including 52 primary breast carcinomas, 10 normal breast tissues and 11 axillary lymph nodes, has been analysed for the presence of amplifications and gross structural alterations, in the oncogenes c-erbB-2, c-erbA, c-myc, N-myc, c-mos and c-Ha-ras. The tumours were also classified, graded and staged histopathologically and their DNA(More)
Methotrexate continues to be one of the most widely used systemic immunosuppressive agents in dermatology. In addition to the important, well-characterized adverse effects such as hepatotoxicity and myelosuppression, methotrexate may induce a number of rare cutaneous adverse events including methotrexate-induced ulceration. We present a case of(More)
The monoclonal antibodies HMFG1 and HMFG2 identify antigens of the milk fat globule membrane which are also found on breast epithelial cells. Immunohistochemical staining was performed using both antibodies on formalin fixed, paraffin embedded sections of 93 breast carcinoma, 36 histologically benign lesions and 29 histologically normal breast tissue(More)
The sites of tumour development for 6 rat tumours injected into syngeneic rats via different vascular routes was determined. Xenografts of human tumours were also injected intra-arterially (i.a.) into immunosuppressed rats. Following intravenous (i.v.) and intraportal (i.ptl.) injection of cells tumour colonies localized in lung and liver respectively due(More)
Malignant lymphoma complicating coeliac disease has been characterised on morphological and immunocytochemical grounds as malignant histiocytosis of the intestine (MHI). Fresh tissue from four cases of MHI was studied by means of a panel of monoclonal antibodies; in three cases tumour DNA was studied for immunoglobulin and T-cell receptor (TCR) gene(More)
The increase in reports of novel diseases in a wide range of ecosystems, both terrestrial and marine, has been linked to many factors including exposure to novel pathogens and changes in the global climate. Prevalence of skin cancer in particular has been found to be increasing in humans, but has not been reported in wild fish before. Here we report(More)
Previous studies of natural killer (NK) activity in the peripheral blood of breast cancer patients have failed to show a reduction in cytotoxicity, an observation at variance with results obtained in other malignancies. Interpretation of the data however is complicated by the presence of treated and post-mastectomy patients in the groups studied.In this(More)
Accumulating evidence suggests autophagy, the principle catabolic process for lysosomal degradation of surplus macromolecules (Roy and Debnath 2010) is fundamental to tumourigenesis. Impaired autophagy results in accumulation of cellular breakdown products, increased oxidative stress and neoplastic transformation (Mathew et al. 2009); whilst efficient(More)
Liver toxicity is a well recognised side-effect of endothelin receptor antagonists (ERAs) (bosentan, sitaxentan and ambri-sentan) and long-term monthly monitoring of liver function tests (LFTs) is mandatory. Sitaxentan is thought to be less commonly associated with liver toxicity compared with the older agent bosentan and has been used as an alternative in(More)
The title of this multiauthor volume is a little misleading. The contributions are based on the proceedings of the 31st annual symposium on the Regulation of Enzyme Activity and Synthesis in Normal and Neoplastic Cells. This was held in Indianopolis in October 1990 so the material is fairly topical. There are 24 papers covering a wide range of subjects. Not(More)
