[Enhancement of bleomycin or hyperthermia induced tumor cell damage by ADPRT inhibitor]. 1992

Institute of Radiation Medicine, Beijing.

Enhancement of tumor cell damage by ADPRT inhibitor, 3-aminobenzamide (3AB) was investigated. 3AB could inhibit DNA strand break repair in HeLa S3 cells after treatment with bleomycin. 3AB was able to lower the clonogenic ability of HeLa S3 cells after bleomycin treatment and hyperthermia. 3AB could also prevent potentially lethal damage repair (PLDR) in HeLa S3 cells treated with bleomycin. This work presents some experimental evidence and theoretical background for the possible use of 3AB as a sensitizer in the treatment of cancer.

UI	MeSH Term	Description	Entries
D006979	Hyperthermia, Induced	Abnormally high temperature intentionally induced in living things regionally or whole body. It is most often induced by radiation (heat waves, infra-red), ultrasound, or drugs.

D001761	Bleomycin	A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.

D004249	DNA Damage	Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.	DNA Injury,DNA Lesion,DNA Lesions,Genotoxic Stress,Stress, Genotoxic,Injury, DNA,DNA Injuries
