Novel and differential accumulation of mitochondrial DNA deletions in Swedish and vietnamese patients with colorectal cancer.

The 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...

Role of Mitochondria in Ataxia-Telangiectasia: Investigation of Mitochondrial Deletions and Haplogroups

Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...

A Novel Large-Scale Deletion of The Mitochondrial DNA of Spermatozoa of Men in North Iran

Genetic Analysis of D-Loop Region of Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study

Background and Objectives: Familial adenomatous polyposis (FAP) is an inherited disorder and a rare form of colorectal cancer. This disease appears equally in both sexes and its occurrence is more in the second or third decade of life. Mutations and alterations of the mitochondrial genome, especially the D-loop region, have been reported in various human tumors. But the exact role of these muta...

Promoter hypermethylation of KLOTHO; an anti-senescence related gene in colorectal cancer patients of Kashmir valley

Hypermethylation of CpG islands located in the promoter regions of genes is a major event in the development of the majority of cancer types, due to the subsequent aberrant silencing of important tumor suppressor genes. KLOTHO; a novel gene associated primarily with suppressing senescence has been shown to contribute to tumorigenesis as a result of its impaired function. Recently the relevance ...
