In accordance with the literature, Alpha-Smooth Muscle Actin (α-SMA), Integrin Beta-1 (CD29), the Fibroblast Activation Protein (FAP), Fibroblast-Specific Protein 1 (FSP1), and Platelet-Derived Growth Factor Beta Receptor (PDGFRβ), are fibroblast markers frequently associated with ovarian cancers [97,98]. The gene discussed is ACTA1; the disease is ovarian carcinoma.
