We studied the pattern of the human VG5Q (AGGF1) mRNA expression in both normal and noeplastic colorectal and bladder tissues. VG5Q mRNA was detected by RT-PCR technique. VG5Q is weekly expressed in the majority of normal cases (n=12). Seven of eight colorectal carcinomas (87.5%) overexpressed VG5Q mRNA when compared to their corresponding normal colorectal tissues of the same patient The level of VG5Q expression in primary tumor is also upregulated in (75%) of the cases when compared to their corresponding liver metastasis. No consistent relationship in the expression level of VG5Q could be deduced when comparing normal colorectal samples to their liver metastasis colorectal tumors. Comparing 4 normal bladder and 16 bladder carcinomas samples reveal that VG5Q expression is also upregulated in bladder carcinomas. The level of VG5Q expression is more frequently upregulated in low grade when compared to high grade bladder carcinomas. These are the first results indicating the association of the newly discovered VG5Q gene transcript with human colorectal and bladder carcinomas. Further studies are needed to evaluate the usage of VG5Q as a complementary histopathologic and a candidate tumor marker among other modalities in both and other types of cancers.
