The NAVBO Meritorious Awards Committee and Council is pleased to announce the selection of Rakesh K. Jain, Ph.D., as the 2018 recipient of the Earl P. Benditt Award, in recognition of his numerous contributions to our understanding of the unique characteristics
of tumor vasculature.
The occurrence of reoxygenation following hypoxic exposures of various degrees is inherent in the dynamic nature
of the tumor vasculature [43, 44].
Not exact matches
«Because the particles are so small, if they happen to reach the
tumor site they have a chance
of penetrating through the blood vessel wall because the
vasculature of tumors is usually leaky.»
Unfortunately, approximately 85 percent
of cancer patients are ineligible for surgery at the time
of diagnosis, either because the
tumor is entwined in critical
vasculature or the disease has progressed too far.
«The enhancing effect was not seen in a patient
tumor sample with a low level
of NRP - 1 expression on the
vasculature.
And because
tumors typically have a leaky, ill - formed
vasculature, the particles tend to leak out at the site
of cancer tissue and be picked up and internalized inside
tumor cells.
Targeting

tumor vasculature of colorectal carcinomas in mice.
Early observations suggesting that the virus might attack cancer in part by damaging blood vessels that feed
tumor growth led the SillaJen team to strike up a collaboration with McDonald, an expert in
tumor vasculature, to investigate the virus's mechanism
of action in animal models.
The irregular
vasculature of solid
tumors creates hypoxic regions, which are characterized by cyclic periods
of hypoxia and reoxygenation.
The NCI's website describes active targeting as «the targeting
of nanoparticles to
tumor cells, microenvironment or
vasculature, as well as directed delivery to intracellular compartments, through nanoparticle surface modification with small molecules, antibodies, affibodies, peptides or aptamers.»
Dr. Jain's nominators note that, in sum, his work has provided ``... unprecedented molecular, cellular, anatomical and functional insights into the vascular pathophysiology
of tumors, for proposing the seminal hypothesis that antiangiogenic therapy can «normalize» the aberrant
vasculature and microenvironment
of tumors and thereby improve both delivery and efficacy
of treatment
of solid
tumors.»
This would bypass the potential adverse effects
of hypoxia on the CSC fraction while limiting
tumor progression due to the general
vasculature effects.

tumors present on both sides without significant evidence
of invasion into the
vasculature or surrounding structures.
