is likely that once the breast milk will no longer be only a source of nutrition for infants.Perhaps it will help to determine the risk of a nursing mother of one of the most feared diseases for women: breast cancer.
study, which is now held by scientific staff of the University of Massachusetts (USA), refers to such complex issues of cancer research, particularly as the methylation of DNA molecules.This is one of the processes that underlie gene expression, ie the implementation of laid down in their genetic information.Earlier studies have already proved that the DNA methylation cancer tumors significantly disrupted.In addition, it is especially important that these biochemical mechanisms of breakage may occur many years before the appearance of the cancer.
However, previous work studying the methylation of breast cancer has been limited by significant cell invasiveness preparation for anal
In the new study, scientists interested in the question whether the useful information can be less traumatic ways.For this purpose, they studied the samples of breast milk from 250 lactating women, the risk of developing breast cancer who was ranked as high.All of the fair sex have declared their willingness to participate voluntarily in the study, which was sponsored by Avon.
Milk samples were collected from both breasts, where it was stored for 24 hours before analysis.Scientists interested in the content of milk cells from which later may develop cancer.This epithelial cells that researchers have isolated DNA for further study.
First of all, they were looking for three genes from a possible 30, which substantially impaired methylation in breast cancer.It appeared that in 13 women with breast cancer was confirmed by biopsy with subsequent histological analysis.And it is these women in cells derived from breast milk, it has been particularly hard disturbed methylation of specific genes.
Head of the work, Dr. Kathleen Arkar (Kathleen F. Arcaro) believes the data is very important.Despite the relatively small number of women who participated in the study, with the transfer of its results to the female population as a whole new method shows significant diagnostic value.Especially this study is important for young mothers, early detection of breast cancer who can help them maintain normal life and raise a child.The work continues, and scientists plan to study further 9 genes associated with impaired methylation in breast cancer.
