General Disease Association:
Cancer
Specific Cancer Types:
Sarcomas; Acute promyelocytic leukemias (APL)
Comments:
Fes has been demonstrated to be an oncoprotein in several human cancer types, potentially due to abnormal activation of the kinase catalytic function. It was originally identified as an oncoprotein from avian retroviral (Fps in Fujinami sarcoma virus) and cat retroviral (Fes in feline sarcoma virus) studies. Interestingly, Fes has also been shown to act as a tumor-suppressor protein in some human cancer types. For example, reduced or absent expression of the Fes protein is observed in colon cancer specimens and the ectopic expression of Fes in colon cancer cell lines results in the suppression of anchorage-independent cell growth, indicating a tumour suppressing role for the Fes protein. In contrast, Fes expression is significantly elevated in prostate cancer specimens and is thought to actively promote cell growth in renal carcinoma cell lines. The Fes gene has been mapped to the long arm of chromosome 15. This chromosomal region has been implicated as a causal factor of acute promyelocytic leukemia, as leukemogenesis of this cancer type is associated with a translocation between chromosome 15 and 17. This translocation has been confirmed in human patients with acute promyelocytic leukemia in which the Fes gene was found to be located on chromosome 17, instead of chromosome 15. In animal studies, mice lacking Fes expression displayed deficits in hematopoiesis and had significantly reduced numbers of circulating mature myeloid cells and immature myeloid precursors, indicating a oncogenic role for the Fes protein in this cancer. In addition, as a result it was also suggested that the Fes protein may have a role in regulating the innate immune response.
Gene Expression in Cancers:
The COSMIC website notes an up-regulated expression score for FES in diverse human cancers of 374, which is 0.8-fold of the average score of 462 for the human protein kinases. The down-regulated expression score of 38 for this protein kinase in human cancers was 0.6-fold of the average score of 60 for the human protein kinases.
Mutagenesis Experiments:
Insertional mutagenesis studies in mice have not yet revealed a role for this protein kinase in mouse cancer oncogenesis.
Mutation Rate in All Cancers:
Percent mutation rates per 100 amino acids length in human cancers: 0.07 % in 25042 diverse cancer specimens. This rate is only -9 % lower and is very similar to the average rate of 0.075 % calculated for human protein kinases in general.
Mutation Rate in Specific Cancers:
Highest percent mutation rates per 100 amino acids length in human cancers: 0.33 % in 805 skin cancers tested; 0.31 % in 830 upper aerodigestive tract cancers tested; 0.29 % in 589 stomach cancers tested; 0.26 % in 1093 large intestine cancers tested; 0.16 % in 846 ovary cancers tested.
Frequency of Mutated Sites:
Most frequent mutations with the number of reports indicated in brackets: E651G (20).
Comments:
Only 1 deletion and no complex mutations, but 18 insertions at A653fs*50 located in the kinase catalytic domain, are noted on the COSMIC website.
