          Abstract

          Aim: To evaluate the serum leptin levels and the effects of flutamide treatment on the leptin levels in women with polycystic ovary syndrome (PCOS). Methods: 20 women with PCOS and 20 controls were enrolled in the study. Leptin levels and leptin response to an oral glucose tolerance test were assessed in both groups before and after a 4-week flutamide therapy period. Results: The leptin levels were similar in both groups at baseline. In the PCOS group, leptin levels and area under curve for leptin levels increased significantly after flutamide treatment. Conclusions: Women with PCOS had similar leptin levels to those of controls with similar age and body mass index. Flutamide treatment led to increased leptin levels and leptin responses to oral glucose tolerance tests in PCOS patients. Further studies are needed to gain insights into the clinical consequences of these effects of flutamide.

          A mutation in the human leptin receptor gene causes obesity and pituitary dysfunction.

          The adipocyte-specific hormone leptin, the product of the obese (ob) gene, regulates adipose-tissue mass through hypothalamic effects on satiety and energy expenditure. Leptin acts through the leptin receptor, a single-transmembrane-domain receptor of the cytokine-receptor family. In rodents, homozygous mutations in genes encoding leptin or the leptin receptor cause early-onset morbid obesity, hyperphagia and reduced energy expenditure. These rodents also show hypercortisolaemia, alterations in glucose homeostasis, dyslipidaemia, and infertility due to hypogonadotropic hypogonadisms. In humans, leptin deficiency due to a mutation in the leptin gene is associated with early-onset obesity. Here we describe a homozygous mutation in the human leptin receptor gene that results in a truncated leptin receptor lacking both the transmembrane and the intracellular domains. In addition to their early-onset morbid obesity, patients homozygous for this mutation have no pubertal development and their secretion of growth hormone and thyrotropin is reduced. These results indicate that leptin is an important physiological regulator of several endocrine functions in humans.

              Design and synthesis of multi-haem proteins.

              A water-soluble, 62-residue, di-alpha-helical peptide has been synthesized which accommodates two bis-histidyl haem groups. The peptide assembles into a four-helix dimer with 2-fold symmetry and four parallel haems that closely resemble native haems in their spectral and electrochemical properties, including haem-haem redox interaction. This protein is an essential intermediate in the synthesis of molecular 'maquettes', a novel class of simplified versions of the metalloproteins involved in redox catalysis and in energy conversion in respiratory and photosynthetic electron transfer.
