Polymer-drug conjugates (polymer therapeutics) are finding increasing use as novel anticancer agents. Here a series of poly(ethylene glycol) PEG-doxorubicin (Dox) conjugates were synthesized using polymers of linear or branched architecture (molecular weight 5000-20000 g/mol) and with different peptidyl linkers (GFLG, GLFG, GLG, GGRR, and RGLG). The(More)
Imatinib is a potent drug used in treatment of chronic myeloid leukaemia (CML). It acts by inhibition of the CML-specific p210 BCR-ABL tyrosine kinase, but also blocks other pathways such as platelet-derived growth factor (PDGF) and c-kit receptor signalling. Clinical trials have confirmed the efficacy of imatinib, which has toxic effects in cells that(More)
Water soluble polymer anticancer conjugates can improve the pharmacokinetics of covalently bound drugs by limiting cellular uptake to the endocytic route, thus prolonging plasma circulation time and consequently facilitating tumor targeting by the enhanced permeability and retention (EPR) effect. Many of the first generation antitumor polymer conjugates(More)
The present study reports the dietary effects of bovine alpha whey fraction, bovine casein and soy protein isolate on the immune responsiveness of C57BL/6J mice infected with Eimeria vermiformis. During the patent period, mice fed alpha whey fraction had significantly higher blood total white cell, CD4+ and CD8+ lymphocyte counts and higher Con A-stimulated(More)
Levels of 9 different oncoproteins and growth factors were assayed by immunoblotting with monoclonal antibodies in 91 serum samples collected between March 1983 and August 1987 from 46 pneumoconiosis patients (36 asbestosis, 10 silicosis) at high risk for the development of cancer. Follow-up of these patients through June 1991 showed that 18 had developed(More)
Firefighters are potentially at increased risk for cancer and non-malignant respiratory disease due to their toxic exposures on the job. Growth factors and oncogene proteins are thought to play a role in the development of various malignancies and pulmonary fibrotic diseases. Therefore, a cohort of firefighters and matched controls have been screened for(More)
