GLOD5 and cancer: The results showed that the HIV peptides with the highest homology to TAAs identified in breast (CCR9), colon (EPCAM, GLOD5, CEACAM8) as well as prostate (NDUFS2) cancer and linked to most frequent HLA alleles (01:01; 02:01 and 24:02), are highly conserved across HIV isolates (Additional file 1: Fig. S5).
