The existence of tumor-suppressor genes was originally demonstrated by functional complementation through whole-cell and microcell fusion. Transfer of chromosome 11 into a human non-small-cell lung cancer (NSCLC) cell line, A549, suppresses tumorigenicity. Loss of heterozygosity (LOH) on the long arm of chromosome 11 has been reported in NSCLC and other(More)
We have recently identified the TSLC1 gene as a novel tumor suppressor in human non-small cell lung cancers. TSLC1 encodes a membrane glycoprotein with an extracellular domain homologous to those of immunoglobulin superfamily proteins. Truncation of TSLC1 in the cytoplasmic domain in a primary human tumor suggests that this domain is important for tumor(More)
A new class of rye-specific repetitive DNA elements designated Superior has been identified. The rye genome library was constructed by cleavage with EcoO109I, the recognition sites of which consisted of 5'-PuGGNCCPy-3' multi-sequences and were present with high frequency in the rye repetitive families. A novel 495-bp segment enriched in the rye genome was(More)
OBJECTIVE To elucidate whether prognosis after acute myocardial infarction can be predicted by measuring plasma adrenomedullin, a novel vasorelaxant peptide. PATIENTS AND DESIGN Plasma adrenomedullin concentrations on day 2 after myocardial infarction were measured in 113 patients with myocardial infarction with other clinical and haemodynamic variables(More)
To investigate the time course of the effects of alcohol on blood pressure, we studied the response of ambulatory blood pressure, neurohumoral variables, and hemodynamics to a single moderate dose of alcohol in hypertensive patients. Sixteen Japanese men (22-70 years old) with essential hypertension who were habitual drinkers were examined under(More)
The causative mechanisms of hypertension were investigated by studying the renal function (pressure-natriuresis) curve in patients with primary aldosteronism (n = 6) and renovascular hypertension (n = 6). Before and after radical operation (removal of adenoma in primary aldosteronism and percutaneous transluminal angioplasty in renovascular hypertension),(More)
To clarify the role of renal prostanoid in hyperreninemia and high blood pressure in human renovascular hypertension, we measured prostaglandin E2 and renin activity in renal venous and abdominal aortic plasma before and after the intravenous administration of the cyclooxygenase inhibitor, aspirin DL-lysine. Subjects were six patients with unilateral(More)
The minimum degree of renal arterial stenosis needed to cause hypertension was identified by renal arterial angiography of anesthetized dogs. The effects of renal nerves and prostanoids on the critical stenosis were also examined. The left renal artery was constricted concentrically by a radiolucent constrictor device, and the stenosis of the artery was(More)
By use of a specific radioimmunoassay for endothelin (ET), the regional distribution of ET-like immunoreactivity (LI) was studied in rats. The antiserum used cross-reacted equally with synthetic porcine and rat ET. Significant amounts of ET-LI are detectable not only in aorta, but also in kidney, lung, heart, liver and central nervous system. Gel(More)
