Previously we have shown that hypoxia strongly induces the expression of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 and -4 (PFKFB-3 and PFKFB-4) genes in several cancer cell lines via a HIF-dependent mechanism. In this paper we studied the expression and hypoxic regulation of PFKFB-4 and PFKFB-3 mRNA as well as its correlation with HIF-1alpha, HIF-2alpha, VEGF and Glut1 mRNA expression in the pancreatic cancer cell line Panc1 and two gastric cancer cell lines MKN45 and NUGC3. This study clearly demonstrated that PFKFB-3 and PFKFB-4 mRNA are expresses in MKN45, NUGC3 and Panc1 cancers cells and that both genes are responsive to hypoxia in vitro. However, their basal level of expression and hypoxia responsiveness vary in the different cells studied. Particularly, PFKFB-3 mRNA is highly expressed in MKN45 and NUGC3 cancer cells, with the highest response to hypoxia in the NUGC3 cell line. The PFKFB-4 mRNA has a variable low basal level of expression in both gastric and pancreatic cancer cell lines. However, the highest hypoxia response of PFKFB-4 mRNA is found in the pancreatic cancer cell line Panc1. The basal level of PFKFB-4 protein expression is the highest in NUGC3 gastric cancer cell line and lowest in Panc1 cells, with the highest response to hypoxia in the pancreatic cancer cell line. Further studies showed that PFKFB-3 and PFKFB-4 gene expression was highly responsive to the hypoxia mimic dimethyloxalylglycine, a specific inhibitor of HIF-alpha hydroxylase enzymes, suggesting that the hypoxia responsiveness of PFKFB-3 and PFKFB-4 genes in these cell lines is regulated by the HIF transcription complex. The expression of VEGF and Glut1, which are known HIF-dependent genes, is also strongly induced under hypoxic conditions in gastric and pancreatic cancer cell lines. The levels of HIF-1alpha protein are increased in both gastric and pancreatic cancer cell lines under hypoxic conditions. However, the basal level of HIF-1alpha as well as HIF-2alpha mRNA expression and their hypoxia responsiveness are different in the MKN45 and NUGC3 cancer cells. Thus, the expression of HIF-1alpha mRNA is decreased in both gastric cancer cell lines treated by hypoxia or dimethyloxalylglycine, but HIF-2alpha mRNA expression is not changed significantly in NUGC3 and slightly increased in MKN45 cells. Expression of PFKFB-4 and PFKFB-3 was also studied in gastric cancers and corresponding nonmalignant tissue counterparts from the same patients on both the mRNA and protein levels. The expression of PFKFB-3 and PFKFB-4 mRNA as well as PFKFB-1 and PFKFB-2 mRNA was observed in normal human gastric tissue and was increased in malignant gastric tumors. The basal level of PFKFB-4 protein expression in gastric cancers was much higher as compared to the PFKFB-3 isoenzyme. In conclusion, this study provides evidence that PFKFB-4 and PFKFB-3 genes are also expressed in gastric and pancreatic cancer cells, they strongly respond to hypoxia via a HIF-1alpha dependent mechanism and, together with the expression of PFKFB-1 and PFKFB-2 genes, possibly have a significant role in the Warburg effect which is found in malignant cells.
