Intestinal ischemia-reperfusion (I/R) is a critical event in the pathogenesis of multiple organ dysfunction syndromes (MODS). The lungs are some of the most vulnerable organs that are impacted by intestinal I/R. The aim of this study is to investigate whether ginsenoside Rb1 can ameliorate remote lung injury induced by intestinal I/R. Adult male Wistar rats were randomly divided into four group...

PURPOSE To further our understanding of the biology and prognostic significance of various chromosomal 13q14 deletions in chronic lymphocytic leukemia (CLL). EXPERIMENTAL DESIGN We analyzed data from SNP 6.0 arrays to define the anatomy of various 13q14 deletions in a cohort of 255 CLL patients and have correlated two subsets of 13q14 deletions (type I exclusive of RB1 and type II inclusive o...

Tumor necrosis factor receptor associated protein 1(TRAP1) is a member of the Hsp90 family that acts as a molecular chaperon to the tumor suppressor retinoblastoma susceptibility gene (RB1). We have previously demonstrated that TRAP1-positive cells contain a high level of cell proliferating genes, whilst TRAP1-negative cells contain a high level of genes involved in cell cycles and metastases. ...

PURPOSE Linkage analysis at the retinoblastoma gene (RB1) locus is required for identification of individuals at risk of developing retinoblastoma and osteosarcoma. Identification of disease causing mutations is necessary for accurate risk prediction. However, the usefulness of direct mutation analysis is impeded by the size and complexity of the RB1 gene. The authors report an alternative poly...

OBJECTIVE Advanced hepatocellular carcinoma (HCC) is a lethal malignancy with limited treatment options. Palbociclib, a well-tolerated and selective CDK4/6 inhibitor, has shown promising results in the treatment of retinoblastoma (RB1)-positive breast cancer. RB1 is rarely mutated in HCC, suggesting that palbociclib could potentially be used for HCC therapy. Here, we provide a comprehensive cha...

BACKGROUND The herb pair of Salvia miltiorrhiza and Panax notoginseng has widely been used for improving coronary and cerebral circulation in China. However, the exact contribution of the major active components of S. miltiorrhiza and P. notoginseng to cardioprotection is far from clear. In the present study, three representative ingredients, salvianolic acid B (SalB) from S. miltiorrhiza and g...

BACKGROUND Lamin A (LMNA) is a component of the nuclear lamina and is mutated in several human diseases, including Emery-Dreifuss muscular dystrophy (EDMD; OMIM ID# 181350) and the premature aging syndrome Hutchinson-Gilford progeria syndrome (HGPS; OMIM ID# 176670). Cells from progeria patients exhibit cell cycle defects in both interphase and mitosis. Mouse models with loss of LMNA function h...

PURPOSE Retinoblastoma (RB), the most common intraocular tumor occurring in infancy and early childhood, is most often related to mutations in the RB1 gene. In this study, we screened the RB1 germline mutations in 41 unrelated Moroccan patients with retinoblastoma, 25 heritable cases, and 16 sporadic unilateral cases. METHODS After complete ophthalmic examinations were performed and consent o...

A method has been devised for the chromatographic resolution of glucosidic compounds, ginseng saponins, on polyethersulphone (PES) membrane. The method results in good resolution and quantitative immunoassay for ginsenoside Rb1 (G-Rb1), G-Rc, and G-Rd in crude extracts of various ginsengs. The newly established method is simpler and applies for quantitative analysis. Ginsenosides developed by a...

Emery-Dreifuss muscular dystrophy (EDMD1) is caused by mutations in either the X-linked gene emerin (EMD) or the autosomal lamin A/C (LMNA) gene. Here, we describe the derivation of mice lacking emerin in an attempt to derive a mouse model for EDMD1. Although mice lacking emerin show no overt pathology, muscle regeneration in these mice revealed defects. A bioinformatic array analysis of regene...
