Mitochondrial DNA Somatic Mutation in Cancer
Cancer cells are known to drastically alter cellular energy metabolism. The Warburg effect has been known for over 80 years as pertaining cancer-specific aerobic glycolysis. As underlying molecular mechanisms are elucidated so that cancer cells alter the cellular energy metabolism for their advantage, the significance of the modulation of metabolic profiles is gaining attention. Now, metabolic ...
متن کاملDetection of Somatic Mutation in Exon 12 of DNA Polymerase β in Ovarian Cancer Tissue Samples
Background: DNA polymerase β (pol β) is a key enzyme of base excision repair pathway. It is a 1-kb gene consisting of 14 exons. Its catalytic part lies between exon 8 and exon 14. Exon 12 has a role in deoxyribonucleotide triphosphate selection for nucleotide transferase activity. Methods: Genomic DNA was isolated from ovarian carcinoma samples. Single strand conformation polymorphism...
متن کاملComprehensive scanning of somatic mitochondrial DNA mutations in breast cancer.
To investigate the role of mitochondrial DNA (mtDNA) in tumorigenesis, a temporal temperature gradient gel electrophoresis method was used to analyze the somatic mtDNA mutations in breast cancer. The entire mitochondrial genomes in 19 tumor samples and paired normal tissues from the same patients were amplified using 32 pairs of overlapping primers. DNA fragments showing different banding patte...
متن کاملSomatic mutation of mitochondrial DNA in cancerous and noncancerous liver tissue in individuals with hepatocellular carcinoma.
Unlike other types of cancer, hepatocellular carcinoma (HCC) is usually preceded by chronic inflammation caused by viral infection. The mutation of mitochondrial DNA (mtDNA) in hepatocarcinogenesis associated with viral infection was investigated. Compared with control liver tissue, the frequency of mtDNA mutations was markedly increased in both noncancerous and cancerous liver specimens from i...
متن کاملSomatic mutation of PTEN in vulvar cancer.
PTEN, a candidate tumor suppressor gene located at chromosome 10q23.3, has been shown to be mutated in approximately 40% of endometrial cancers. Such mutations have also been identified in endometrial hyperplasia, indicating that inactivation of the PTEN tumor suppressor gene is an early event in the genesis of some endometrial cancers. In this study, we have extended the analysis of PTEN in gy...
