VEGF Spliced Variants: Possible Role of Anti-Angiogenesis Therapy

VEGF Spliced Variants: Possible Role of Anti-Angiogenesis Therapy

Angiogenesis has been targeted in retinopathies, psoriasis, and a variety of cancers (colon, breast, lung, and kidney). Among these tumour types, clear cell renal cell carcinomas (RCCs) are the most vascularized tumours due to mutations of the von Hippel Lindau gene resulting in HIF-1 alpha stabilisation and overexpression of Vascular Endothelial Growth Factor (VEGF). Surgical nephrectomy remai...

Pazopanib and anti-VEGF therapy

Pazopanib (Votrient™, GlaxoSmithKline), a multi-kinase inhibitor with activity against VEGFR and other receptors, was recently approved by the FDA for the treatment of advanced renal cell carcinoma (RCC). Here, we review the history of its development, together with an overview of VEGF and its receptors and co-receptors. Results from selected clinical trial data in RCC and other malignant disea...

ANTI-VEGF THERAPY FOR DIABETIC MACULAR EDEMA Anti-VEGF Therapy For Diabetic Macular Edema

Anti-VEGF Agents for Ocular Angiogenesis and Vascular Permeability

We review articles describing intravitreal injection of anti-VEGF drug trials, while discussing the mechanisms of the action of anti-VEGF antibodies, and also evaluating their outcomes. Intraocular injections of anti-VEGF drug are considered to be an effective treatment for macular edema after retinal vein occlusion, however, recurrent/persistent edema is common. The recent reports may lead to ...

Tumor refractoriness to anti-VEGF therapy

Vascular endothelial growth factor (VEGF) has been identified as the most potent cytokine involved in tumor angiogenesis and metastasis formation. Clinical results of anti-angiogenic therapies targeting VEGF and its receptors are very modest, resulting in a moderate improvement of overall survival. The clinical outcome is associated with the development of resistance and the increased risk of i...
