ABSTRACT

Simple Summary WWOX is a gene that plays a key role in regulating cellular processes related to maintaining homeostasis and protecting against cancer, through interactions with many proteins and signalling pathways. One of the important partners of WWOX is the hypoxia inducible factor HIF1α. Through this interaction, WWOX modulates cancer cell metabolism, which serves as an important prognostic factor. This study assessed the prognostic significance of the WWOX/HIF1A ratio in various cancers: breast cancer subtypes, glioblastoma multiforme, low-grade glioma, and hepatocellular carcinoma. It was found that in breast cancer, the WWOX/HIF1A ratio allows for the identification of groups of patients with favourable and unfavourable prognosis—in basal and HER2 breast cancer subtypes, high WWOX/HIF1A was associated with a more favourable prognosis, whereas in luminal A and B subtypes, it correlated with a less favourable prognosis. In the remaining analysed cancers, a higher WWOX/HIF1A expression ratio also allowed for determining the prognosis; in brain tumours and hepatocellular carcinoma, it clearly correlated with better survival. In conclusion, the WWOX/HIF1A expression ratio might be considered as a potential biomarker determining the prognosis of cancer patients.
