Methods The expression levels of these genes were determined with RT-PCR and the protein levels and expression using ELISA and IHC methods, respectively. Results In RT-PCR analysis, statistically significant upregulated expression was determined of 1.84-fold of BAP1, 2.85-fold of OGT and 3.06-fold of YY1 genes (p < 0.05). In the patient group, compared to the control group, there was a similar statistically significant strong correlation between the proteins (BAP1 and YY1; r = 0.850, BAP1 and OGT; r = 0.811, OGT and YY1; r = 0.755) (p < 0.05). In the ELISA and IHC analysis methods, a significant increase in BAP1 and YY1 protein expression levels was observed compared to the control group (p < 0.05). Conclusions The study results demonstrated that BAP1 and YY1 genes and protein levels were upregulated in eyelid tumor tissue with BCC.eninfo:eu-repo/semantics/openAccessBAP1basal cell carcinomaexpressioneyelidOGTtumorYY1Article46670971910.1515/tjb-2021-01602-s2.0-85123446713Q4WOS:000734474200001Q4
