OBJECTIVE To summarize the evidence linking dietary habits to the incidence of several types
of cancer with special emphasis on the chemoprotective properties of foods that originate …

The blood–brain barrier (BBB) restricts the entry of proteins as well as potential drugs to
cerebral tissues. We previously reported that a family of Kunitz domain‐derived peptides called …

p‐glycoprotein (p‐gp) is an ATP‐binding cassette transporter and its overexpression is
responsible for the acquisition of the multidrug resistance phenotype in human tumors. p‐gp is …

We have investigated the effects of different biologically active components from natural
products, including green tea polyphenols (GTP), resveratrol, genistein and organosulfur …

Recent evidence indicates that bone-marrow-derived stromal cells (MSCs) have a histology
coherent with endothelial cells that may enable them to contribute to tumor angiogenesis …

By controlling access to the brain, the blood-brain barrier (BBB) restricts the entry of proteins
and potential drugs to cerebral tissues. We demonstrate here the transcytosis ability of …

Many beneficial proprieties have been associated with polyphenols from green tea, such as
chemopreventive, anticarcinogenic, antiatherogenic and antioxidant actions. In this study, …

The stimulation of vascular endothelial growth factor receptor-2 (VEGFR-2) by tumor-derived
VEGF represents a key event in the initiation of angiogenesis. In this work, we report that …

The blood–brain barrier (BBB) performs a neuroprotective function by tightly controlling access
to the brain; consequently it also impedes access of proteins as well as pharmacological …

1. The blood–brain barrier (BBB) contributes to brain homeostastis and fulfills a protective
function by controlling the access of solutes and toxic substances to the central nervous …
