What can we learn from miRNA?
(Insert Figure left) miRNA are small units of RNA that play a regular role in gene regulation. miRNA binds and cleaves messenger RNA, inhibiting gene expression. There are hundreds of miRNA, and their profile and activity vary between different cell types. This makes it is possible to tell the difference between cells from the uterus and liver based on miRNA profiles. Furthermore, cells from the uterus of women with endometriosis have been found to have dysregulated miRNA in comparison to cells from the uterus of women who do not have endometriosis().
