Biochem/physiol Actions

c-Fos is a proto-oncogene, which is the human homolog of the retroviral oncogene v-fos. It is one of the essential transcription factors that helps in initiation of adipocyte differentiation.6 FOS protein expression in human glioma is found to be strong and probably plays a critical role in the progression of gliomas.7 c-Fos may be involved in regulating lipid synthesis.8 c-Fos is associated with prognosis of ovarian cancer (OvCa) by changing the adhesion of OvCa cells to peritoneal surfaces.9
