From the dichloromethane extract of Ulex airensis three new isoflavonoids, ulexin C (1), ulexin D (2), and 7-O-methylisolupalbigenin (3), were isolated and characterized by spectroscopic methods. Ulexin D (2) was also identified from the dichloromethane extract of Ulex europaeus ssp. europaeus.
A new naturally occurring isoflavone, derrone, was isolated from Ulex jussiaei (Leguminosae) together with the isoflavones ulexins A-C, lupalbigenin, isolupalbigenin, 7-O-methylso-lupalbigenin, isoderrone, ulexone A and isochandalone, the pterocarpans (6aR,11aR)-(-)-maackiain,
In this study, lectin binding was compared with pathological prognostic factors and clinical follow-up details. Formalin-fixed, paraffin-embedded tissues from 43 cases of breast carcinoma were studied for binding with Ulex Europeus Agglutinin (UEA-I) lectin. Staining results were compared with tumor
Aleuria aurantia lectin (AAL) is an L-fucose-specific lectin produced in the mycelia and fruit-bodies of the widespread ascomycete fungus Aleuria aurantia. It is extensively used in the detection of fucose, but its physiological role remains unknown. To investigate this, we analyzed the interaction
BACKGROUND
Lymphangiosarcoma is a rare, aggressive malignancy that originates from the endothelial cells lining lymphatic vessels and carries an extremely poor prognosis. Its clinical and histologic features are often indistinguishable from angiosarcoma.
OBJECTIVE
We sought to better characterize
Tumor metastasis is usually a serious problem in tumor patients because of the lack of therapeutic approaches. A new compound, N-all-trans-retinoyl-L-proline (ATRP), has been developed and its metastasis inhibition activity has been studied. Low concentrations of ATRP have already been found to
Number and function of endothelial progenitor cells (EPCs) are down-regulated in patients with coronary artery disease (CAD). Integrin-linked kinase (ILK) is a signal and adaptor protein that regulates survival of mature endothelial cells and vascular development. Here we show that EPC dysfunction
Patients with critical limb ischemia (CLI) have low levels of endothelial progenitor cells (EPC). Iloprost has been demonstrated to stimulate vascular endothelial growth factor (VEGF) and promote angiogenesis. We investigated the effects of iloprost on EPC levels in vivo in CLI patients.
In a prospective study investigating the therapeutic role of anagrelide in myelofibrosis with myeloid metaplasia, 20 patients received anagrelide in daily oral doses of 0.5-3 mg. 17 patients were evaluable and received anagrelide for a median of 2 years (range 0.5-4 years). No patient had a
We examined the staining pattern of various lectins in the malignant and benign prostatic tissues to clarify the difference of sugar residues of mucosubstances between them. The binding of different lectins (Concanavalia ensiformis [Con A], Triticum vulgaris [WAG], Ricinus communis [RCA-I], Arachis
BACKGROUND
Lung cancer remains the leading cause of cancer-related death, largely owing to the lack of effective treatments. A tumour vascular targeting strategy presents an attractive alternative; however, the molecular signature of the vasculature in lung cancer is poorly explored. This work aimed
Blood-derived adult stem cells were previously considered impractical for therapeutic use because of their small numbers. This report describes the isolation of a novel human cell population derived from the peripheral blood, termed synergetic cell population (SCP), and defined by the expression of
Surface engineering of nanoparticles with lectins opened a novel pathway to improve the brain uptake of agents loaded by biodegradable PEG-PLA nanoparticles following intranasal administration. Ulex europeus agglutinin I (UEA I), specifically binding to l-fucose, which is largely located in the
We have used rhesus monkey embryonic stem (ES) cells to study endothelial cell development. Rhesus ES cells (R366.4 cell line) exposed to medium containing vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), insulin-like growth factor (IGF), and epidermal growth factor
OBJECTIVE
Animal studies have indicated that pancreatic exocrine acinar cells have phenotypic plasticity. In rodents, acinar cells can differentiate into ductal precursors that can be converted to pancreatic ductal adenocarcinoma or insulin-producing endocrine cells. However, little is known about
