Decreased mRNA expression of GATA1 and GATA2 is associated with tumor aggressiveness and poor outcome in clear cell renal cell carcinoma

GATA-binding proteins 1 (GATA1) and 2 (GATA2) are zinc-finger transcription factors and belong to the GATA family proteins 1–6. GATA1 interacts with the TP53 tumor suppressor gene, and both GATAs have been shown to be involved in cell growth, apoptosis, and tumorigenesis of several solid tumors. GATA1 and GATA2 expression alterations are associated with poor survival and adverse clinicopathology in prostate and colorectal cancer, while the significance and prognostic value in clear cell renal cell carcinoma (ccRCC) has not been investigated as yet. We investigated relative messenger RNA (mRNA) expression levels of GATA1 and GATA2 in 77 ccRCC and 58 paired adjacent noncancerous renal tissues by quantitative real-time reverse-transcribed PCR. Relative mRNA expression levels were determined using the ΔΔCt method. GATA1 and GATA2 expression levels were significantly decreased in tumor tissues compared with normal tissues (p
