Abstract:
In the present work we sought to investigate the content of sphingolipids (sphingosine, sphinganine, sphingosine-1-phosphate and ceramide) in human fibroids and pair-matched healthy uterus tissue. We demonstrated that, in uterine leiomyomas, the contents of sphingosine, sphinganine, sphingosine-1-phosphate and ceramide remains quite constant. However, a trend towards elevation of ceramide and simultaneous reduction of sphingosine-1 phosphate levels was also noticed. Additionally, in uterine leiomyomas we found relevant activation of both PTEN and MAPK(ERK1/2) signaling pathways with only a minor change in AKT activity and relatively absent HIF-1α/AMPK activation. In conclusion, rather modest changes in sphingolipids are correlated with the activation of PTEN and MAPK(ERK1/2) signaling proteins in human uterine leiomyomas.

In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
