Result(s)
To date, the pathogenesis of uterine leiomyomas is not well understood. However, genetic alterations (especially MED12 and HMGA2) and involvement of epigenetic mechanisms (DNA methylation, histone modifications, and microRNA) in leiomyoma provide the clue of initiator of this tumor. Estrogens and P are considered as promoters of leiomyoma growth, and growth factors, cytokines, and chemokines are thought to be as potential effectors of estrogens and P. Extracellular matrix components are a major structural part of leiomyoma tissue that are abnormally orientated and can modify mechanical stress on cells, which leads to activation of internal mechanical signaling and may contribute to leiomyoma growth.
Conclusion(s)
Besides many genetics and epigenetic factors, the important link among the sex steroids, growth factors, cytokines, chemokines, and extracellular matrix and their involvement in cell proliferation, fibrotic processes, apoptosis, and angiogenesis are implicating a complex network in leiomyoma formation and growth. Those findings could provide information to establish future therapeutic options for the management of this tumor.
