Expression levels of immune control points genes in renal cell carcinoma

Abstract

The introduction of new drugs based on the inhibition of immune control points (ICР) into cancer therapy has significantly improved the prognosis for patients. However, such therapy is not always effective. To reveal the possible reasons for this, we studied the expression levels of PD-L1 and other ICР genes - IDO1, CEACAM1, PVR, TDO2, CD276, GAL9 and ADAM17 in samples of clear cell renal cell carcinoma. The analysis revealed the genes most often expressed together with PD-L1 - IDO1, TDO2, CD276, GAL9 and ADAM17. Significant correlation with the expression of PD-L1 was found for the expression of ADAM17, PVR, and CD276 genes. The data obtained may be important for the further development of therapy based on blocking ICP, including PD-L1.
