BAENA, Juvenal et al. EDNRB and CDX2 expression as possible biomarkers in progression to cervical cancer. Rev. colomb. biotecnol [online]. 2018, vol.20, n.1, pp.6-15. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v20n1.64114.

According into account the natural history of cervical cancer, where low- and high-grade preneoplastic lesions may present regression or progression phenomena, there is great interest in the search for biomarkers to predict the behavior of preneoplastic lesions of the cervix. These biomarkers may be of genetic origin, or epigenetics that alter the expression of genes and that may be associated with carcinogenesis in different types of human tissue. The objective of the study was to analyze the expression of the mRNA of the SFRP1, PTPRN, CDO1, EDNRB, CDX2, EPB41L3 and HAND1 genes in samples negative for cervical intraepithelial lesions (n = 9), low grade intraepithelial lesions (n=10) and high grade (n = 11). Expression analysis of the mentioned genes was performed using qRT-PCR and data analysis was performed using the non-parametric ANOVA test. The statistical difference was determined in values p <0.05. For the EDNRB and CDX2 genes, a 66.7% decrease was observed in the samples without cervical histological alterations, compared to a decrease in expression of 50% in LIEBG samples and 36.4% in the LIEAG group for the EDNRB gene And 27.3% for the CDX2 gene giving a statistically significant difference p = 0.02. Suggesting that EDNRB and CDX2 could be useful as potential biomarkers in cervical carcinogenesis.
