XIST Gene Deletion in Breast Cancer Therapy

September 16, 2019 updated by: CN Fayez, Assiut University

Detection of XIST Gene Deletion by Fluorescence in Situ Hybridization in Patients With Breast Cancer and Its Relation With Different Response to Therapies

Very little is known about the role of X-inactive specific transcript RNA in human breast cancer and in regulating different response to therapy .

the relation between the breast cancer predisposing gene BRCA1 & X-inactive specific transcript RNA has been investigated but still controversial.

Loss of X chromosome inactivation (XCI) is observed in breast cancer . Other studies sheds light on a possible mechanism of breast carcinogenesis mediated by XIST misbehaviour.

Detailed Description

breast cancer is an important cause of morbidity and mortality in women .Genetics of female contributes to her risk of having breast cancer . this disease is still discovered in their late stages due to the negligence of females inspite of self inspection and clinical examination of the breast .the identification of markers that could predict the tumor behavior is important in breast cancer management , staging, evaluation of therapeutic response and development of new therapeutic modalities .XIST (X-inactive specific transcript) RNA is a long non -coding RNA which plays an important role in inactivation of x_ chromosome which act as an example for long non _ coding RNA mediated gene regulation .Very little is known about the role of XIST in human breast cancer and in regulating different response on therapy . the relation between the breast cancer predisposing gene BRCA1 & XIST has been investigated but still controversial .Loss of X chromosome inactivation (XCI) is observed in breast . some studies provide evedience that BRCA1 Is involved in XIST regulation on the active X chromosome but not its localization .other studies sheds light on a possible mechanism of breast carcinogenesis mediated by XIST misbehaviour .
