Chromosomal damage and ageing: effect on micronuclei frequency in peripheral blood lymphocytes.

BACKGROUND Instability in the organization and expression of the genetic material has been hypothesized as the basic mechanism of ageing. OBJECTIVE To quantify the effect of ageing on chromosomal damage as measured by spontaneous micronuclei (MN) frequency in peripheral blood lymphocytes. METHOD Analysis of a large population sample from two laboratories applying the cytokinesis-block techn...

G2 chromosomal radiosensitivity and background frequency of sister chromatid exchanges of peripheral blood lymphocytes of breast cancer patients

Background: Chromosomal alterations play an important role in carcinogenesis. Enhanced chromosomal radiosensitivity is shown for many cancer predisposition conditions including breast cancer. In this study chromosomal radiosensitivity and the frequency of background sister chromnatid exchanges (SCE) in lymphocytes of normal individuals and breast cancer patients was compared. Materials...

Induction of DNA damage, apoptosis and micronuclei in peripheral blood lymphocytes following injection of contrast media in patients with abdominal CT scan

Background: Medical diagnostic procedures such as X-ray and computed Tomography (CT) scan account for considerable percent of patient's exposure to ionizing radiation. The exposure of cells to Ionization radiation results in induction of DNA damage and chromosomal aberrations. Contrast media (CM) are widely used in diagnostic radiology and CT scan. The aim of this study was to study adverse gen...

High frequency of micronuclei in peripheral blood lymphocytes as index of susceptibility to pleural malignant mesothelioma.

We evaluated the frequency of micronuclei (MN) in peripheral blood lymphocytes of patients with pleural malignant mesotelioma (MM), lung cancer, benign respiratory diseases, and healthy controls. A significant increased frequency of MN was observed in patients with MM in comparison with all the other groups (median, 11.4 binucleated MN/1000 binucleated cells versus 5.1, 6.1, and 6.2, respective...

Abstract: Biological Effect Monitoring in Peripheral Blood Lymphocytes from Subjects Occupationally Exposed to Antineoplastic Drugs: Assessment of Micronuclei Frequency: Milena

Antineoplastic drugs (ANPDs) are a heterogeneous group of chemicals that include alkylating agents (e.g., cyclophosphamide, melphalan, chlorambucil), antimetabolites (e.g., thioguanine, 5-fluorouracil, methotrexate), antibiotics (e.g., doxorubicin), mitotic spindle inhibitors (e.g., vincristine), hormones (e.g., diethylstilbestrol, free radical generators (e.g., bleomycin) and topoisomerase inh...
