The accuracy of prostate cancer staging in a population-based tumor registry and its impact on the Black-White stage difference (Connecticut, United States)
Stage at diagnosis of prostate cancer is a major determinant of survival. Among Blacks, prostate cancer is diagnosed at a later stage of disease than among Whites. This study examined the accuracy of routine c...

The establishment of two cell lines from a mouse uterine cervical carcinoma (U14) and their metastatic phenotype changes
This paper studies the heterogeneity of metastatic potential of murine cervical carcinoma (U14). Two cell lines, P11–90 and L10–90, were established from a pulmonary metastatic substrain (U14AP11) and a lymphatic...

Regulation of desmosomal cell adhesion in human tumour cells by polyunsaturated fatty acids
Desmosomes are key structures in cell-cell adhesion. In this study we examined the effect of n-6 essential fatty acids on the expression of desmoglein (Dsg), desmosomal cadherin and the formation of desmosomes...

Comparison between `in vivo' and `in vitro' methods for evaluating tumor angiogenesis using cervical carcinoma as a model
The role of angiogenesis in tumorigenesis is widely accepted. Therefore, it is mandatory to develop a clinically useful method for assessing tumor angiogenesis. This study was designed to compare the `in vivo' an...

Open AccessPreferential down-regulation of phospholipase C-β in Ewing’s sarcoma cells transfected with antisense EWS-Fli-1
EWS-Fli-1, a fusion gene found in Ewing’s sarcoma and primitive neuro-ectodermal tumour (PNET), encodes a transcriptional activator and promotes cellular transformation. We have made stable Ewing’s sarcoma cel...

Article
Production and characterization of a Tie2 agonist monoclonal antibody
The Tie2 receptor and its known ligands, the angiopoietins, play a critical role in endothelial cell differentiation during the process of angiogenesis. Recent experimental observations indicate that the agoni...

Article
Distinct regulation of genes by bFGF and VEGF-A in endothelial cells
A finely tuned balance of angiogenic inhibitors and inducers controls the activity of angiogenesis characterized by proliferation, migration and differentiation of endothelial cells. Among many angiogenic fact...

Open AccessTyrphostin AG 1024 modulates radiosensitivity in human breast cancer cells
Insulin-like growth factor-1 (IGF-1) plays an important growth-promoting effect by activating the PI3K/Akt signalling pathway, inhibiting apoptotic pathways and mediating mitogenic actions. Tyrphostin AG 1024,...

The thin prep rat aortic ring assay: A modified method for the characterization of angiogenesis in whole mounts
The rat aortic ring model has gained broad acceptance as an angiogenic assay. This system can be used to study the activity of angiogenic and anti-angiogenic factors, and investigate the molecular mechanisms o...

Induction of focal angiogenesis through adenoviral vector mediated vascular endothelial cell growth factor gene transfer in the mature mouse brain
Vascular endothelial growth factor (VEGF) is a potent endothelial cell mitogen and morphogen, which stimulates angiogenesis in a wide variety of tissues and lesions in vivo. In this study, we applied adenoviral v...

Article
Gangliosides regulate tumor cell adhesion to collagen
The ability of tumor cells to adhere to extracellular matrix proteins is critical for migration and invasion. The factors that regulate tumor cell adhesion are poorly characterized. Gangliosides promote platel...

The Mouse Aorta Model: Influence of Genetic Background and Aging on bFGF- and VEGF-Induced Angiogenic Sprouting
Angiogenesis can be studied ex vivo by culturing rat or mouse aortic rings in collagen gels. Unlike rat aorta explants, unstimulated mouse aortic rings were unable to spontaneously produce an angiogenic response ...

Open Accessn-3 Polyunsaturated fatty acids decrease mucosal/epidermal reactions and enhance antitumour effect of ionising radiation with inhibition of tumour angiogenesis
The purpose of this study was to evaluate the effect of n-3 polyunsaturated fatty acids (n-3 PUFAs) on normal tissue (lip mucosa) and tumour growth when combined with ionising radiation. The oral region (snout...
