Bioactive function

Cysteine-rich protein 61 (Cyr61/CCN1) is an angiogenic factor and a member of a family of growth factor-inducible immediate-early genes with functions in cell adhesion, pro-liferation and differentiation.We investigated the regulatory mechanisms and signaling pathways involved inCyr61/ CCN1gene activation in smoothmuscle cells.Treatment of these cells with sphingosine 1-phosphate (S1P), a bioactive lysolipid, increased rapidly but transiently the expression of theCyr61/CCN1gene at both themRNAandprotein levels....

Peptides function as chemical signals between cells of multicellular organ-isms via specific receptors on target cells. Many hormones, neuromodula-tors and growth factors are peptides. Peptide hormones and other biologically active peptides are synthesized as higher molecular weight pre-cursor proteins (pro-hormones), which must undergo post-translational modification to yield the bioactive peptide(s).

In the early 1980’s, the Japanese were the first to recognize dairy components as having significant contributions to “physiologically functional foods.” Since then there has been an increasing number of investigations that have supported this view.Current evidence for the health benefits of most dairy foods and dairy components is based primarily on in vitro and in vivo animal studies. Human clinical studies are still needed in many areas.
