Fleshy fruits are classically divided into climacteric and nonclimacteric types. It has long been thought that the ripening of climacteric and nonclimacteric fruits is regulated by ethylene and abscisic acid (ABA), respectively. Here, we report that sucrose functions as a signal in the ripening of strawberry (Fragaria × ananassa), a nonclimacteric fruit.(More)
Angiogenesis is a complex process that involves endothelial cell proliferation, migration, basement membrane degradation, and neovessel organization. Angiostatin, consisting of four homologous triple-disulfide bridged kringle domains, has previously been shown to exhibit profound inhibition of endothelial cell proliferation in vitro and angiogenesis in(More)
We report the isolation and characterization of a third isoform of placenta growth factor (PlGF), generated by alternative splicing of its RNA transcript. This novel form of PlGF, PlGF-3, was cloned by the polymerase chain reaction technique using a human cDNA library prepared from the terminal placental tissue. PlGF-3 contains an in-frame insertion of(More)
Angiogenesis is a multi-step process that includes endothelial cell proliferation, migration, basement membrane degradation, and new lumen organization. Angiostatin, an internal fragment of plasminogen comprising the first four triple disulfide-linked kringle structures, is one of the most potent endogenous angiogenesis inhibitors described to date.
