Epidermal growth factor
Growth factors are polypeptides that are critical for the initiation, progression, and metastasis of cancer. Most tumor cells are capable of synthesizing particular growth factors leading to constitutive pathway activation in these cells through autocrine signaling. Epidermal growth factor (EGF) is a potent mitogenic peptide that exerts direct effects on the proliferation and differentiation of tumor cells in carcinogenesis.
The aim of this study was to verify the association between the epidermal growth factor (EGF) +61 G/A polymorphism and the susceptibility to endometriosis using a case-control design study. The control group included fertile women without endometriosis and the case group included endometriosis patients. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to genotype the EGF +61 G/A polymorphism. Initially, a total of 184 individuals were analyzed.
