Interleukin 8 production and interleukin 8 receptor expression in human myometrium and leiomyoma.
Interleukin 8 is a potent chemoattractant cytokine that is expressed in a variety of human tumors and is known to induce mitogenesis. We aimed to investigate the production of interleukin 8 and the expression of its receptor in myometrium and leiomyoma, in which we hypothesized that interleukin 8 may contribute to cellular proliferation.L M Senturk, I Sozen, L Gutierrez, A Arici

Isolated growth hormone deficiency: analysis of the growth hormone (GH)-releasing hormone gene and the GH gene cluster.
Isolated GH deficiency (IGHD) cannot be distinguished on the grounds of anti-human (h) GH antibodies and stunted growth response to exogenous hGH. DNA analysis was proposed to classify children with IGHD. Genomic DNA was extracted and studied by restriction endonuclease analysis after extraction from the circulating lymphocytes of 53 children with IGHD. These children included 5 pairs of siblings and 5 individuals from 10 families, whose parents (n = 20) and brothers and sisters (n = 5) were also analyzed. Twenty-five adults, including individuals from 3 families of normal height, were studied as controls. No deletion within the hGH gene cluster was identified using a [32P]hGH cDNA clone as a probe. A compound heterozygosity for a hGH-1 deletion or a mutation have not been found. The allelic frequencies for 5 common restriction fragment length polymorphisms were similar in patients and controls. The distribution and frequency of the distinct haplotypes in the hGH gene family revealed no differences between IGHD (n = 30 chromosomes) and controls (n = 48 chromosomes). No deletion or restriction fragment length polymorphisms could be found using a hGH-releasing hormone cDNA clone as a probe in patients or controls. This large volume of data gathered from a caucasian population indicates that the great majority of patients with IGHD has no structural abnormalities of the hGH gene cluster, particularly no hGH-1 gene deletion. In addition, they have no gross deletions within the hGH-releasing hormone gene.P Mullis, M Patel, P M Brickell, C G Brook

Release of the 22,000- and the 20,000-dalton variants of growth hormone in vivo and in vitro by human anterior pituitary cells.
Using a combination of polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate and immunoblotting with antihuman GH (anti-hGH) serum, we quantitatively and independently measured the major 22,000-dalton form of hGH (hGH22K) and the 20,000-dalton form (hGH20K). This technique was equally effective in assaying cell culture media or human sera. We studied isolated human pituitary cell cultures during a 16-day incubation period with and without stimulation by GH-releasing hormone (GHRH). Under basal conditions, the cells released 2.83 +/- 0.24 (+/- SEM) microgram hGH22K/ml . day and 0.67 +/- 0.17 microgram hGH20K/ml . day. GHRH (10(-8) M) treatment resulted in stimulation of both hGH22K and hGH20K by 24 h. We also measured both hGH22K and hGH20K in the sera of normal subjects before and after an iv bolus injection of 100 micrograms GHRH. hGH20K increased as did hGH22K. Peak concentrations of both variants occurred 45 min after GHRH administration. The results of this study indicate that the combination of sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting is an accurate and effective means of separately assaying hGH22K and hGH20K. We also demonstrated that primary monolayer cultures of human pituitary cells are an excellent model system for study of the secretion of these two hGH variants.E Markoff, D W Lee, F L Culler, K L Jones, U J Lewis
