Abstract
Endometriosis is a disease common in women of reproductive age, characterized by pelvic
pain and infertility. Despite its prevalence, the factors and mechanisms which contribute
to the development and survival of ectopic lesions remain uncertain. MicroRNAs (miRNAs)
are small RNA molecules that regulate posttranscriptional gene regulation which have
been proposed to contribute to the pathogenesis of many diseases including that of
endometriosis. This review summarizes the results of initial studies describing differentially
expressed miRNAs between endometriotic lesion tissue and eutopic endometrium. Focus
then moves toward discussion of studies on examining function of differentially expressed
miRNAs to determine if they play a permissive role (driver of the disease) in events
conducive to endometriosis progression/survival. Included in this discussion are the
potential targets of these miRNAs and how their mis-expression may contribute to the
disease. Limitations and challenges faced in studying miRNAs and endometriosis pathogenesis
and recommendations to overcome these hurdles are presented at the end.
