Numerous clinical trials are being conducted to assess the benefits of using commercial preparations containing G. frondosa extracts in cancer treatment. We tested a commercially available product containing polysaccharides from the G. frondosa (CGFP) and studied their effect on gene expression in Jurkat T cells. An mRNA differential display was performed to gain insight into the cell response to the substance. HAI1, hnRNP A2/B1, PKC iota, KLRC1, and genes of the ubiquitin system were identified as possible regulators in the mechanism of tumor-suppressor action of CGFP. Real-time polymerase chain reaction (qPCR) was used to investigate the effect of CGFP on cytokine expression in Jurkat T cells. The qPCR results showed that the expression of the gene for IL-5 is increased. %8 2010-08-24
