Abstract:
Epithelial ovarian cancer (EOC) is the most common and deadly ovarian cancer. Most of the patients have abdominal/pelvic invasion and metastasis at the time of diagnosis, but the underlying mechanism remains unclear. Insufficiency of blood perfusion and diffusion within most solid tumors can lead to a hypoxic tumor microenvironment and promotes tumor malignancy. In the present study, we detected the role of the spermatogenesis- and oogenesis-specific basic helix-loop-helix (bHLH) transcription factor 2 (sohlh2) on migration, invasion and epithelial-mesenchymal transition (EMT) of EOC cell lines under hypoxia in vitro. We also investigated the possible mechanism underlying it. The results showed that sohlh2 inhibited the migration, invasion and EMT of EOC cells and might function through suppression of the hypoxia-inducible factor 1α (HIF1α)/carbonic anhydrase 9 (CA9) signaling pathway. Our results may open a new avenue for the further development of diagnostic tools and novel therapeutics that will benefit EOC patients.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
