To correlate the variable clinical features of oestrogen-receptor-positive breast cancer with somatic alterations, we studied pretreatment tumour biopsies accrued from patients in two studies of neoadjuvant aromatase inhibitor therapy by massively parallel sequencing and analysis. Eighteen significantly mutated genes were identified, including five genes(More)

We collected a total of 78 tissue specimens, including primary colorectal carcinoma, normal colonic mucosa, and liver metastases of colon carcinoma, to examine whether the extracts of these tissues inhibited the binding of a monoclonal antibody FH6, specific for sialyl-dimeric LeX antigen. The results of inhibition assays demonstrated that: (a) contents of(More)
The quantity and localization of two lactose-binding lectins with molecular weights of 31,000 and 14,500 in human colorectal carcinoma tissue specimens obtained by surgical resection have been studied using specific polyclonal antibodies. Electrophoretic separation and blotting of detergent extracts of tumor tissues (48 specimens), followed by the binding(More)
Sulfated macromolecules synthesized in tumor and mucosa tissues derived from colorectal cancer patients were labeled with [35S]sulfate and separated into two fractions on DEAE-Sephacel: the slightly acidic peak (peak I) was eluted with 0.2 M NaCl and the highly acidic peak (peak II) was eluted with 0.5 M NaCl. A total of 40 specimens, which included primary(More)

Previous studies using metabolic labeling of fresh colonic mucosa and colorectal carcinoma with [35S]sulfate followed by biochemical analysis demonstrated that the amount of a sulfated high-molecular-weight glycoprotein expressed in primary colorectal carcinoma was lower than that in normal mucosa, and that the amount further decreased in liver metastases.(More)
The search for a hormonal marker in breast cancer has centered on estrogens and their metabolites. However, direct measurements of total amounts of these steroids have shown no convincing or consistent differ ences between normal women and women with breast cancer. The purpose of this study was to measure the percentages of non-protein-bound estradiol(More)
The purpose of this study was to evaluate the effect of a concomitant infusion of ornithine on the difluoromethylornithine (DFMO)-induced thrombocytopenia and antitumor activity. Male Fischer 344 rats with either a transplantable fibrosarcoma or Ward colon tumor were given a 12-day continuous infusion of DFMO (2000 mg/kg/day) alone or with ornithine. The(More)
Polycarbonate cages were modified with clear plastic dividers so that up to four mice could be housed individually in one cage with ad libitum access to feed and water. The method used commercially available components and was applicable for use in any study when it was necessary to keep mice separate for an extended period of time.
