Growth of new blood vessels (angiogenesis), required for all tumor growth, is stimulated by the expression of vascular endothelial growth factor (VEGF). VEGF is up-regulated in all known solid tumors but also in atherosclerosis, diabetic retinopathy, arthritis, and many other conditions. Conventional VEGF isoforms have been universally described as proangiogenic cytokines. Here, we show that an...
RATIONALE Systemic sclerosis (SSc) is characterized by widespread microangiopathy, fibrosis, and autoimmunity. Despite the lack of angiogenesis, the expression of vascular endothelial growth factor A (VEGF) was shown to be upregulated in SSc skin and circulation; however, previous studies did not distinguish between proangiogenic VEGF(165) and antiangiogenic VEGF(165)b isoforms, which are gener...
Recent studies have suggested that serum levels of vascular endothelial growth factor (VEGF) may provide useful prognostic information in patients with various types of cancers. However, there has been a debate on whether serum VEGF level is a true reflection of tumor angiogenic activity in cancer patients. This debate originates from the finding that most VEGF in the serum is released from pla...
Angiogenesis and vascular regression are critical for the female ovulatory cycle. They enable progression and regression of follicular development, and corpora lutea formation and regression. Angiogenesis in the ovary occurs under the control of the vascular endothelial growth factor-A (VEGFA) family of proteins, which are generated as both pro-(VEGF(165)) and anti(VEGF(165)b)-angiogenic isofor...
BACKGROUND AND PURPOSE Receptor tyrosine kinase inhibitors (RTKIs) targeted at VEGF receptor 2 (VEGFR2) have proved to be attractive approaches to cancer therapy based on their ability to reduce angiogenesis. Here we have undertaken a quantitative analysis of the interaction of RTKIs and two VEGF splice variants, VEGF(165)a and VEGF(165)b, with VEGFR2 by studying nuclear factor of activated T-c...
It has been documented that hypoxia enhances coronary vasculogenesis and angiogenesis in cultured embryonic quail hearts via the upregulation of vascular endothelial growth factor (VEGF). In this study, we compared the functions of two VEGF splice variants. Ventricles from 6-day-old embryonic quail hearts were cultured on three-dimensional collagen gels. Recombinant human VEGF(121) or VEGF(165)...
Introduction: Cloxacillin is the second most prescribed antibiotic for skin and soft tissue infection in Malaysia. A similar pattern was seen Kuala Selangor, which our district demonstrated that Defined Daily Dose (DDD) of high (3.0-8.7) compared to recommended value from World Health Organization (WHO). However, resistant patterns are alarming. This study focuses on appropriate use prevent fur...
