Growth hormone releasing hormone (GHRH) receptor binding has been characterized using a unique binding assay utilizing iodinated GHRH probes. Photoaffinity GHRH probes have been constructed which allow for photolabeling and characterization of the receptor. In addition, high affinity biotinylated GHRH analogs have been constructed. Solubilization of GHRH-R/GHRH complexes and extraction of specifically bound GHRH using a mild detergent solution, followed by affinity chromatography, leads to a substantially purified GHRH-R isolate. Electrophoretic treatment of the GHRH-R isolate produces GHRH-R of sufficient purity to conduct sequencing of the receptor. Cloning of a gene encoding for polypeptides (protein or fragments thereof) having GHRH-R activity is accomplished using a bacterial host, and the cloned gene is expressed in a mammalian cell line. In addition, molecular cloning of the ovine GHRH-R is provided.

Pathological regional adipose tissue accumulation associated with HIV-associated dysmorphic/dysmetabolic syndrome (HADDS) which may occur with or without subcutaneous adipose tissue lipodystrophy (and which is also described as HIV-associated adipose redistribution syndrome or HARS and other specific medical terms), is treated by administering an effective amount of human growth hormone or other substance which binds to and initiates signalling of the hGH receptor. Alternatively, a substance which stimulates production of endogenous hGH, such as human growth hormone releasing hormone, may be administered. HADDS and related syndromes include abnormal adipose tissue accumulation in the visceral, submandibular, supraclavicular, pectoral, mammary and/or dorsocervical (buffalo hump) area, and/or with subcutaneous lipomas, with or without associated metabolic or other physiologic abnormalities.
