Exploring oxysterols and protein carbonylation in cervicovaginal secretions as biomarkers for cervical cancer development

Cervical cancer, a major global health issue and the fourth most common cancer among women, is strongly linked to Human Papillomavirus (HPV) infection. Emerging evidence indicates that oxidative stress plays a critical role in the carcinogenesis of cervical tissue. This study investigates the relati...

description Cervical cancer, a major global health issue and the fourth most common cancer among women, is strongly linked to Human Papillomavirus (HPV) infection. Emerging evidence indicates that oxidative stress plays a critical role in the carcinogenesis of cervical tissue. This study investigates the relationship between oxidative stress markers—specifically oxysterols, lipid oxidation, and protein carbonylation—and the progression of cervical neoplasia.Oxysterols, which are elevated in various inflammatory diseases and cancers, were measured in cervicovaginal fluid samples using LC-MS/MS. The targeted oxysterols included 27-hydroxycholesterol (27-OHC), 7β-hydroxycholesterol (7β-OHC), 7-ketocholesterol (7-KC), and 7α,27-dihydroxycholesterol (7α,27-diOHC). Among these, 7α,27-dihydroxycholesterol was significantly increased in correlation with the severity of neoplastic stages. In parallel, protein carbonylation, an indicator of cellular oxidative stress, was assessed. Results revealed higher levels of protein carbonylation in neoplastic samples compared to non-neoplastic controls. These modifications were further analysed through redox proteomics to identify the specific proteins affected.The study demonstrates that elevated lipid oxidation and protein carbonylation in cervicovaginal secretions are linked to the development and progression of cervical cancer. Identifying these biomarkers may improve screening strategies, enabling the identification of individuals at increased risk for cervical neoplasia and guiding timely interventions.
