modifications of ribosomal RNAs. Loss of SNORP functions is believed to contribute to Prader-Willi syndrome. Molecular diagnosis of these syndromes is based on assessment of methylation status of marker genes and FISH. The importance of imprinting is not restricted to rare chromosomal disorders. Parent-of-origin effects have been identified in a variety of inherited diseases, such as Huntington disease and myotonic dystrophy and in tumorigenesis. Key Concepts Genomic Imprinting ▪
Nailfold capillary loops are distorted early in the course of disease, and later they disappear. Telltale signs of endothelial activation and injury (e.g., increased levels of von Willebrand factor) and increased platelet activation (increased percentage of circulating platelet aggregates) have also been noted. However, what causes the vascular injury is not known; it could be the initiating event or the result of chronic inflammation, with mediators released by inflammatory cells inflicting

signaling pathways that ultimately induce the production of proteins that are involved in driving cells through the cell cycle and other proteins that release blocks on the cell cycle (checkpoints) (Chapter 1). In addition to responding to growth factors, cells use integrins to bind to ECM proteins, and signals from the integrins can also stimulate cell proliferation. In the process of regeneration, proliferation of residual cells is supplemented by development of mature cells from stem cells.
