HMGA2 and leiomyoma: Additionally, the overexpression of HMGA2 in leiomyomas was shown to be associated with increased vasculature density, demonstrated by the increased expression of angiogenic factors and receptors, such as VEGFA, EGF, bFGF, TGFα, VEGFR1, and VEGFR2, which likely contribute to tumour growth [180].
