A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Cholesterol‐enriched plasma membranes in hepatocellular carcinoma impede drug penetration. Cholesterol (+)‐liposomes act as membrane‐specific detergents, extracting cholesterol and reducing barrier function without cytotoxicity. Following endocytosis, cholesterol transfers from endosomes to liposomes and is metabolized in the ER.

According to the somatomedin model, growth hormone (GH)-dependent hepatic synthesis is responsible for maintaining circulating insulin-like growth factor (IGF)-I levels. On the other hand, the local autocrine/paracrine IGF-I expression in peripheral tissue is generally GH-independent and reflects the effects of various and tissue-specific trophic ...

Insulin-like Growth Factor-I in Growth and Metabolism
Journal of Pediatric Endocrinology and Metabolism, 2010Deficiency of insulin-like growth factor-I (IGF-I) results in growth failure. A variety of molecular defects have been found to underlie severe primary IGF-I deficiency (IGFD), in which serum IGF-I concentrations are substantially decreased and fail to respond to GH therapy.

Colocalization of insulin-like growth factor-binding protein with insulin-like growth factor I
American Journal of Physiology-Renal Physiology, 1991We report the localization of insulin-like growth factor I (IGF-I) and a 25-kDa form of insulin-like growth factor-binding protein (IGF-BP-1) in adult rat kidney. The antigens were localized using a rabbit anti-human IGF-I antibody, and a rabbit anti-human IGF-BP-1 antibody raised against human 25-kDa IGF-BP-1 purified from amniotic fluid ...

Insulin-Like Growth Factor -I Deficiency
Hormone Research in Paediatrics, 2001The insulin-like growth factor (IGF) system composed of two ligands, their receptors and regulatory proteins (acid-labile subunit and IGF-binding proteins) plays a central role in the regulation of growth and development in mammals. In addition to its key role in the stimulation of cellular proliferation and growth, IGF-I has important effects on ...

Insulin‐like growth factor I actions on steroidogenesis
Acta Paediatrica, 1994The best evidence that insulin‐like growth factor I (IGF‐I) contributes to normal steroidogenesis comes from patients with growth hormone (GH) insensitivity syndrome due to deletion of the GH receptor gene. These patients have severe GH resistance and severe IGF‐I insufficiency, and present with markedly delayed puberty without gonadotrophin ...
