NUCL EAR DNA CONTENT AND DNA PLOIDY ANALYSIS IN BREAST CANCER
To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...
متن کاملIncreased incidence of retroperitoneal teratomas and decreased incidence of sacrococcygeal teratomas in infants with Down syndrome.
Individuals with Down syndrome (DS) have a unique profile of neoplasms, with a higher incidence of leukemias and a lower incidence of solid tumors than seen in the general population. We recently encountered two cases of infants with DS with retroperitoneal teratoma. After reviewing the literature on teratomas in DS, we found that the incidence of retroperitoneal teratomas was higher and the in...
متن کاملDNA content measurement for DNA ploidy and cell cycle analysis.
This unit presents the most common methods of DNA content analysis. The techniques differ primarily in the mode of cell permeabilization (detergents versus prefixation with alcohol) and composition of the stain solution. Protocols are given for analysis of fixed cells, tissue samples, live cells (for subsequent sorting and culture), archival paraffin-embedded tissue, and apoptotic cells.
متن کاملFlow cytometric DNA ploidy analysis of ovarian granulosa cell tumors.
The nuclear DNA content of 50 ovarian tumors initially diagnosed as granulosa cell tumors was measured by flow cytometry using paraffin-embedded archival material. The follow-up period of the patients ranged from 4 months to 19 years. Thirty-eight tumors were diploid or near-diploid, while 5 were aneuploid. DNA profiles of 7 tumors could not be evaluated. All 50 tumors were immunohistochemicall...
متن کاملMeasurement of ploidy and cell proliferation in the rodent liver.
In most investigations of cell proliferation in vivo, the population under study consists of mononuclear diploid cells that undergo replication via normal complete division cycles. Because the phenomena associated with the cell cycle are sequential, only one is normally measured and it is usually adequate to quantify the proliferative activity in one of two ways. The first involves labeling the...
