Ligand-dependent and -independent effects of splice variant 1 of growth hormone-releasing hormone receptor.

Comparison of Expression of Growth Hormone-Releasing Hormone and Its Receptor Splice Variant 1 in Different Stages of Endometriosis

Expression of neuropeptide hormone receptors in human adrenal tumors and cell lines: antiproliferative effects of peptide analogues.

Peptide analogues targeting various neuropeptide receptors have been used effectively in cancer therapy. A hallmark of adrenocortical tumor formation is the aberrant expression of peptide receptors relating to uncontrolled cell proliferation and hormone overproduction. Our microarray results have also demonstrated a differential expression of neuropeptide hormone receptors in tumor subtypes of ...

Antiproliferative effect of growth hormone-releasing hormone (GHRH) antagonist on ovarian cancer cells through the EGFR-Akt pathway

BACKGROUND Antagonists of growth hormone-releasing hormone (GHRH) are being developed for the treatment of various human cancers. METHODS MTT assay was used to test the proliferation of SKOV3 and CaOV3. The splice variant expression of GHRH receptors was examined by RT-PCR. The expression of protein in signal pathway was examined by Western blotting. siRNA was used to block the effect of EGFR...

The immunohistochemical expression of growth hormone-releasing hormone receptor splice variant 1 is a favorable prognostic marker in colorectal cancer.

Hypothalamic growth hormone (GH)-releasing hormone (GHRH) regulates the release of GH from the pituitary gland. The receptors for GHRH (GHRH-R) are expressed predominantly in the pituitary. Recent evidence demonstrates that splice variants of the GHRH receptor are also expressed in several nonpituitary tissues, both normal and tumoral, as well as in cancer cell lines. The aim of this study was ...

Kinetic analysis of the internalization and recycling of [3H]TRH and C-terminal truncations of the long isoform of the rat thyrotropin-releasing hormone receptor-1.

The C-terminal tail of the long splice variant of the rat thyrotropin-releasing hormone (TRH) receptor-1 (TRHR-1L) comprises around 93 amino acids. A series of C-terminal truncations was constructed and expressed transiently in HEK-293 cells. The extent of steady-state internalization of these in response to [(3)H]TRH was dependent upon the degree of truncation. Little effect was produced by de...
