Background

GRPR mediates signals of cellular proliferation and it has been shown to be aberrantly expressed in several cancers such as colon, lung, ovary, pancreas and prostate. It also expressed at very high levels in normal pancreas and at lower levels in brain, breast, colon, lung, lymph node, ovary, placenta, prostate, stomach and uterus.
