FSHR and colonic neoplasm: Moreover since the follicle-stimulating hormone receptor FSH-R has been shown to be expressed by the vascular endothelium in several human cancers [45] as well as in tumor metastases [46], including colon cancer [47], the detection of SexH receptors by RT-PCR may reflect the expression of SexH receptors on the surface of tumor-associated cells of the vasculature.
