P-201: Prevalence of 4977bp Deletion in Mitochondrial DNA in IVF Failure Women
نویسندگان
چکیده مقاله:
Background: Successful IVF process is limited by factors such as oocyte quality. Oocyte quality can be defined as its abilities to be fertilized, mature and give rise to normal offspring and it is dependent on nuclear maturation and cytoplasm maturation. Damage to mitochondrial DNA (mtDNA) has been described in oocytes in IVF failure women that decrease cytoplasmic quality because Mitochondria are essential for respiration and oxidative phosphorylation of the cell. The presence of mtDNA 4977bp deletion in many different tissues can serve as a marker of this damage. However, no attempt has been made to detect the presence of mtDNA 4977bp in blood cells of these women. This is the first report concerning the 4977bp deletion in IVF failure women. Materials and Methods: Polymerase chain reaction techniques (PCR) were used to detect mtDNA 4977bp deletion in blood samples of 100 IVF failure women and compared with 100 women who had success IVF procedure. Results: The prevalence of 4977bp deletion in mtDNA was 88% in IVF failure women and 45% in control samples. Conclusion: The higher prevalence of mtDNA 4977bp deletion in patients in this study indicates that damage to mtDNA in blood cells can serve as a marker that demonstrate reduced quality of oocyte.

Mitochondrial DNA 4977bp Deletion Mutation in Peripheral Blood Reflects Atrial Remodeling in Patients with Non-Valvular Atrial Fibrillation
PURPOSE Recently, mitochondrial DNA 4977bp deletion (mtDNA4977-mut), a somatic mutation related to oxidative stress, has been shown to be associated with atrial fibrillation (AF). We hypothesized that patient age, as well as electroanatomical characteristics of fibrillating left atrial (LA), vary depending on the presence of mtDNA4977-mut in peripheral blood among patients with non-valvular AF....

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...

Background: P53, p63, and p73 transcription factors which are belong to The p53 family, are conserved during evolution. They have important roles in many molecular and cellular functions, including tumor suppression, the development of epithelial cell layers, and the development of central nervous system and immune system. Studies show these molecules also have role in maintaining the genomic i...
