Mitochondrial DNA 4977 BP deletion mutations in lung carcinoma.
BACKGROUND The most common and also the most often assayed mtDNA deletion mutation, degrees mtDNA 4,977 sub has been demonstrated in various types of human cancer. However, knowledge about degrees mtDNA 4,977 in lung carcinoma is poor. AIM To study the 4,977 bp deletions of mitochondrial DNA ( degrees mtDNA 4,977) in lung cancer, adjacent histologically normal and normal lung tissue and its p...
متن کاملMitochondrial DNA content and 4977 bp deletion in unfertilized oocytes.
Previous studies analysing the incidences of mitochondrial DNA (mtDNA) deletions and mtDNA content in unfertilized oocytes in relation to donors' age have been controversial. The objective of the study was to compare these two parameters in unfertilized oocytes and relate them to the donors' age. Fifty-two women donated 155 unfertilized metaphase II (MII) oocytes. The incidence of 4977 bp delet...
متن کاملThe Mitochondrial DNA 4977-bp Deletion in Patients with Colorectal Cancer: a Case-control Study in Iran
Colorectal cancer (CRC) is the third leading cause of cancer-related death worldwide, and its occurrence can be ascribed to genetic susceptibility. Mitochondrial DNA 4977-bp (mtDNA 4977), as the most described mtDNA deletion, has been long proposed to be involved in various types of cancers. However, a few studies on mtDNA 4977-bp deletion in Iranian patients with CRC have been reported. The cu...
متن کاملSensitive detection of the 4977-bp deletion in human mitochondrial DNA of young individuals.
Specific deletions in mitochondrial DNA (mtDNA) are present at high levels in skeletal muscle and other tissues (7). It has been suggested that an accumulation of these somatic deletions could be caused by oxidative damage that increases with age (2). In recent years, more than 20 different types of deletions have been identified using polymerase chain reaction (PCR) techniques (16). The most f...
متن کاملDetection of mitochondrial DNA with 4977 bp deletion in leukocytes of patients with ischemic stroke
BACKGROUND Coronary artery disease is associated with a common mitochondrial DNA alteration, a 4977 bp deletion (mtDNA4977). The role of mtDNA4977 in ischemic stroke is unknown. METHODS Real-time quantitative PCR was performed to quantify total mtDNA and mtDNA4977 in leukocytes in 283 ischemic stroke cases and 135 controls. Ratios of mtDNA4977 to total-mtDNA and total-mtDNA to nuclear-DNA wer...
