The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: OBJECTIVE To clarify the relationship between the expression of pol beta and DNA damage /repair induced by Benzo(a)pyrene ( BaP ) . METHODS pol beta wild-type cells ( pol beta +/+ ) , pol beta null cells ( pol beta -/- ) and wild-type pol beta overexpressed cells ( pol beta oe ) which had the same genetic background were studied . Firstly , RT-PCR and Western blot targeting to pol beta were carried out to measure the expression of pol beta mRNA and protein in above three kinds of cells , then MTT test and single cell gel electrophoresis ( comet assay ) were used to compare cell viability and DNA damage/repair of the three kinds of cells when exposed to BaP . RESULTS There was pol beta deletion in pol beta -/- cells and the level of pol beta mRNA and protein in pol beta oe cells was twice higher than that in pol beta +/+ cells . BaP could induce DNA damage and reduce cell viability , when compared with pol beta +/+ cells , IC50 of pol beta -/- cells was remarkably lower , DNA was prone to damage and more difficult to be repaired , on the other hand , IC50 of pol beta oe cells was obviously higher and the damage effect on DNA was weaker and prone to be repaired . CONCLUSION Pol beta played an important role in the repair of DNA damage induced by BaP , deficiency of pol beta could decrease the DNA repair capability of cells , and overexpression of pol beta could help cells response to DNA damage and protect cells from death in a certain degree .
