Chromosomal radiosensitivity in two cell lineages derived from clinically radiosensitive cancer patients.
PURPOSE Despite its prominent contribution to cancer cure and palliation, around 1% to 5% of cancer patients suffer serious side effects from radiotherapy. A cardinal goal in the fields of radiobiology and oncology is to predict normal tissue radiosensitivity of a cancer patient before radiotherapy. Higher tumor control rates are likely if radiotherapy individualization could be achieved by app...
متن کاملTelomere length abnormalities in mammalian radiosensitive cells.
Telomere lengths in radiosensitive murine lymphoma cells L5178Y-S and parental radioresistant L5178Y cells were measured by quantitative fluorescence in situ hybridization. Results revealed a 7-fold reduction in telomere length in radiosensitive cells (7 kb) in comparison with radioresistant cells (48 kb). Therefore, it was reasoned that telomere length might be used as a marker for chromosomal...
متن کاملAdenosine deaminase messenger RNAs in lymphoblast cell lines derived from leukemic patients and patients with hereditary adenosine deaminase deficiency.
Hereditary deficiency of adenosine deaminase (ADA) usually causes profound lymphopenia with severe combined immunodeficiency disease. Cells from patients with ADA deficiency contain less than normal, and sometimes undetectable, amounts of ADA catalytic activity and ADA protein. The molecular defects responsible for hereditary ADA deficiency are poorly understood. ADA messenger RNAs and their tr...
متن کاملThe Expression of Heme Oxygenase-1 in Human-Derived Cancer Cell Lines
Background: Heme oxygenase-1 (HO-1) is a cytoprotective and antiapoptotic enzyme, which has been involved in maintaining cellular homeostasis, and plays an important protective role by modulating oxidative injury. Up-regulation of (HO-1) has contributed to tumorogenicity of some cancers. In this study we investigated the expression pattern of the HO-1, in five different human-derived cancer cel...
متن کاملCancer stem cells from colorectal cancer-derived cell lines.
Cancer stem cells (CSCs) are the subpopulation of cells within a tumor that can self-renew, differentiate into multiple lineages, and drive tumor growth. Here we describe a two-pronged approach for the identification and characterization of CSCs from colorectal cancer cell lines, using a Matrigel-based differentiation assay, and cell surface markers CD44 and CD24. About 20 to 30% of cells from ...
