Detection of damage-recognition proteins from human lymphocytes.
نویسندگان
چکیده
Proteins recognizing and binding to damaged DNA (DDB-proteins) were analyzed in human lymphocytes obtained from healthy donors. Using an electrophoretic mobility shift assay several complexes between nuclear extract proteins and damaged DNA were detected: a complex specific for DNA damaged by N-acetoxy-N-acetylaminofluorene, another complex specific for UV-irradiated DNA, and two complexes specific for DNA damaged by cis-dichlorodiammine platinum. All the detected complexes differed in electrophoretic mobility and possibly contained different proteins. Complexes specific for free DNA ends were also detected in protein extracts from lymphocytes.

Studies on electron beam induced DNA damage and repair kinetics in lymphocytes by alkaline comet assay
Background: Exposure to ionizing radiation is known to induce oxidative stress followed by damage to critical biomolecules like lipids, proteins and DNA through radiolysis of cellular water. Since radiation has been widely used as an important tool in therapy of cancer, the detailed investigation regarding the DNA damage and repair kinetics would help to predict the radiation sensitivity of cel...
متن کاملSEPARATION OF NONHISTONE HIGH MOBILITY GROUP (HMG) FROM HUMAN LYMPHOCYTES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...

Objective: Ferula szowitsiana has been widely used for medicinal purposes around the world. The anti-oxidant effect of F.szowitsiana had been proved. The current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from F. szowitsiana, against hydrogen peroxide (H2O2) - induced oxidative DNA damage in human lymphocytes. Materials and Methods: Human lymphocyt...
متن کاملExposure to Antineoplastic Agents Induces Cytotoxicity in Nurse Lymphocytes: Role of Mitochondrial Damage and Oxidative Stress
Cytotoxicity and mitochondrial parameters were studied in isolated lymphocytes and their mitochondria obtained from occupationally exposed nurses through inhalation exposure to antineoplastic drugs and results were compared to those of unexposed nurses. The group of occupationally exposed nurses consisted of 50 individuals ranging in age from 30 to 35 years. The control group included 50 nurses...
