The major yolk protein (MYP) in sea urchins has historically been classified as a vitellogenin based on its abundance in the yolk platelets. Curiously, it is found in both sexes of sea urchins where it is presumed to play a physiological role in gametogenesis, embryogenesis, or both. Here we present the primary structure of MYP as predicted from cDNAs of(More)
Mounting evidence has demonstrated that a specialized extracellular matrix exists in the mammalian brain and that this glycoprotein-rich matrix contributes to many aspects of brain development and function. The most prominent supramolecular assemblies of these extracellular matrix glycoproteins are perineuronal nets, specialized lattice-like structures that(More)
The major yolk protein of sea urchins is an iron-binding, transferrin-like molecule that is made in the adult gut. Its final destination though is the developing oocytes that are embedded in somatic accessory cells and encompassed by two epithelial layers of the ovary. In this study, we address the dynamics of yolk transport, endocytosis, and packaging(More)
OBJECTIVE To understand if patient-provider race-concordance is associated with improved health outcomes for minorities. DESIGN A comprehensive review of published research literature (1980-2008) using MEDLINE, HealthSTAR, and CINAHL databases were conducted. Studies were included if they had at least one research question examining the effect of(More)
Sea urchin oocytes grow to 10 times their original size during oogenesis by both synthesizing and importing a specific repertoire of proteins to drive fertilization and early embryogenesis. During the vitellogenic growth period, the major yolk protein (MYP), a transferrin-like protein, is synthesized in the gut, transported into the ovary, and actively(More)
The Life Sciences-Howard Hughes Medical Institute Outreach Program at Harvard University supports high school science education by offering an on-campus program for students and their teachers to participate in investigative, hands-on laboratory sessions. The outreach program has recently designed and launched a successful zebrafish embryology protocol that(More)
