BACKGROUND Angiogenesis is essential for tumor growth and progression. Therefore, inhibition of angiogenesis is being studied as a new anticancer therapy. Because cytotoxic chemotherapy is more effective on rapidly growing tumors than on slowly growing tumors, it has been assumed that antiangiogenic therapy will also be effective only on rapidly growing, highly vascularized tumors. We compared ...

CORRECTION After the publication [1] it came to the attention of the authors that one of the co-authors was incorrectly included as Hamza Somrain. The correct spelling is as follows: Hamzeh Sumrein.

Forty years on from its worldwide withdrawal, thalidomide is currently undergoing a remarkable renaissance as a novel and powerful immunomodulatory agent. Over the last decade it has been found to be active in a wide variety of inflammatory and malignant disorders where conventional therapies have failed. Recently, considerable progress has been made in elucidating its complex mechanisms of act...

Angiogenesis is a very complex physiological process, which involves multiple pathways that are dependent on the homeostatic balance between the growth factors (stimulators and inhibitors). This tightly controlled process is stimulated by angiogenic factors, which are present within the tumor and surrounding tumor-associated stromal cells. The dependence of tumor propagation, invasion and metas...

If your Snark be a Snark, that is right: Fetch it home by all means-you may serve it with greens, And it's handy for striking a light. "But oh, beamish nephew, beware of the day, If your Snark be a Boojum! For then You will softly and suddenly vanish away, And never be met with again!" Lewis Carroll The Hunting of the Snark

Enzyme Activity Stimulates Angiogenesis In Vivo: A Potential Downside To the Editor: The study by Fabre et al,1 which demonstrates that tissue inhibition of angiotensin-converting enzyme (ACE) activity stimulates angiogenesis in the rabbit model of hindlimb ischemia, has profound implications that require investigation. Specifically, should ACE inhibitors be contraindicated in individuals with ...

Inhibition of angiogenesis has emerged as a key focus for the treatment of cancer, necessitating a better understanding of the downstream molecular targets of angiogenesis inhibitors. Endostatin, thrombospondin-1, fumagillin, and its synthetic derivative, TNP-470, are potent inhibitors of endothelial cell proliferation and migration in culture and of angiogenesis in vivo. To identify targets th...
