Mechanical stress-induced Hippo signaling in respect to primordial follicle development and polycystic ovary syndrome pathogenesis

Abstract

Polycystic ovary syndrome (PCOS) is a heterogeneous reproductive disease that can cause infertility. The Hippo signaling pathway, a network highly conserved throughout evolution, maintains the balance between follicle proliferation and dormancy. Dynamic changes in primordial follicles cannot occur without the participation of biological signals and mechanical force; however, little is known about the mechanism by which biomechanical signaling triggers PCOS, especially in the context of primordial follicle development. To investigate the contribution of mechanical stress and the Hippo signaling pathway to the onset of PCOS, we searched the literature via the PubMed database, and inclusion and exclusion criteria were established to ensure the rigor of this research. We eventually included 54 publications in which Hippo signaling and mechanical force were suggested to play a vital role in the development of primordial follicles as well as elucidate the pathogenesis of PCOS. The Hippo pathway modulating follicle growth can be perturbed via extracellular mechanical stress caused by the stiff ovarian cortical environment in PCOS. Clinical intervention targeting the Hippo pathway can alter the activity of core Hippo members, such as the Yes-associated protein/ transcriptional co-activator PDZ-binding motif complex. In some patients with PCOS, follicle overactivation can be attributed to the dysfunction of Hippo signal transduction. PCOS, a condition with various patterns, cannot be accurately explained by a single, specific mechanism. The present review identifies potential targets and therapeutic strategies for PCOS.
