چکیده

Breast Cancer (BC) is considered as one of the most important causes of death worldwide. Previous studies showed that apolipoprotein B mRNA- editing catalytic polypeptide-like 3 (APOBEC3) gene deletion significantly increased the risk of BC risk in Chinese and European women. The present study aimed to assess the possible impact of APOBEC3 deletion and the risk of BC in a sample of Iranian population. The APOBEC3 insertion/deletion (I/D) was analyzed in a case- control study including 262 BC patients and 217 healthy women. Polymerase chain reaction (PCR) was used to genotype the variant in APOBEC3 gene. The findings of this study showed that I/D as well as I/D+D/D genotype increased the risk of BC (OR= 1.57, 95% CI= 1.07- 2.31, p= 0.025 and OR= 1.50, 95% CI= 1.03- 2.19, p= 0.037, respectively) in comparison with I/I genotype. In conclusion, our findings suggest that APOBEC3 deletion polymorphism increased the risk of BC in an Iranian population in the southeast of Iran.

A 40-bp Insertion/Deletion Polymorphism of Murine Double Minute2 (MDM2) Increased the Risk of Breast Cancer in Zahedan, Southeast Iran

Background: MDM2 (Murine Double Minute2) is an oncoprotein that inhibits the P53 activity. Overexpression of MDM2 gene has been reported in several human tumors. In the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of MDM2 and susceptibility to breast cancer in a sample of Iranian population. Methods: This case-control study wa...

APOBEC3 deletion polymorphism is associated with breast cancer risk among women of European ancestry.

Copy number variations occur frequently in the genome and are a significant source of human genetic variation accounting for disease. Recently, we discovered a common deletion located in the APOBEC3A and APOBEC3B genes significantly associated with breast cancer in Chinese women. Investigating this locus in other populations would be an expedient way to evaluate the generalizability of the nove...

بررسی ارتباط مولکولی جهش حذف 5395bp ژن CHEK2 و ابتلا به سرطان پستان

Background & Objectives: Breast cancer is the most common cancer among women and the second most common cause of cancer death. Genetic factors play an important role in the development of breast cancer. Among these genetic factors, CHEk2 (checkpoint kinase 2) gene, as a tumor suppressor gene, plays a critical role in DNA repair. Germline mutations in CEHK2 result in the loss of this feature. On...
