In mammalian cells, Id proteins coordinate proliferation and differentiation. Id2 is a dominant-negative antagonist of basic helix-loop-helix transcription factors and proteins of the retinoblastoma (Rb) family. Here we show that Id2-Rb double knockout embryos survive to term with minimal or no defects in neurogenesis and haematopoiesis, but they die at(More)
PURPOSE To investigate the activity and toxicity of gemcitabine as a single agent in patients with advanced non-small-cell lung cancer (NSCLC) after recurrence or failure of previous treatment with a platinum-containing regimen. PATIENTS AND METHODS From November 1995 to October 1997, 83 patients with stage IIIB or IV NSCLC received gemcitabine 1,000(More)
Cardiac progenitor/stem cells in adult hearts represent an attractive therapeutic target for heart regeneration, though (inter)-relationships among reported cells remain obscure. Using single-cell qRT-PCR and clonal analyses, here we define four subpopulations of cardiac progenitor/stem cells in adult mouse myocardium all sharing stem cell antigen-1 (Sca1),(More)
Cardiac muscle creation during embryogenesis requires extracellular instructive signals that are regulated precisely in time and space, intersecting with intracellular genetic programs that confer or fashion the ability of the cells to respond. Unmasking the essential signals for cardiac lineage decisions has paramount importance for cardiac development and(More)
The elucidation of factors that activate the regeneration of the adult mammalian heart is of major scientific and therapeutic importance. Here we found that epicardial cells contain a potent cardiogenic activity identified as follistatin-like 1 (Fstl1). Epicardial Fstl1 declines following myocardial infarction and is replaced by myocardial expression.(More)
Retinoic acid (RA) has several established functions during cardiac development, including actions in the fetal epicardium required for myocardial growth. An open question is if retinoid effects are limited to growth factor stimulation pathway(s) or if additional actions on uncommitted progenitor/stem populations might drive cardiac differentiation. Here we(More)
AIM Mutations in a sarcomeric protein can cause hypertrophic cardiomyopathy (HCM) or dilated cardiomyopathy (DCM), the opposite ends of a spectrum of phenotypic responses of the heart to mutations. We posit the contracting phenotypes could result from differential effects of the mutant proteins on interactions among the sarcomeric proteins. To test the(More)
Within the developing and adult heart, the fibroblast is often dismissed as merely a structural element, important just to mechanical integrity or to scarring when excessive in disease. Ieda et al. in this issue of Developmental Cell now report an essential program of paracrine factor production in cardiac fibroblasts that controls heart muscle cell growth,(More)
AIM Brain natriuretic peptide (BNP) is a cardioactive molecule produced in the myocardium. BNP is a sensitive marker of cardiac failure and its measurement in blood could be useful to the diagnosis and the treatment of this disease. Sporting activities, especially endurance ones, can induce cardiac problems, owing to the high workload for the myocardium(More)
26 previously treated patients with progressive recurrent small cell lung cancer (SCLC) were given vinorelbine (Navelbine), 30 mg/m2 weekly. All patients had responded to first-line chemotherapy and were off therapy for at least 3 months. Partial response was observed in 4 out of 25 eligible patients (16%; 95% confidence interval 4-36%), stable disease in 7(More)
