  • Patent number: 8648231
    Abstract: The disclosure relates to methods for modulating plant growth and organogenesis using dominant-negative receptor-like kinases. The disclosure further provides a method for increasing plant yield relative to corresponding wild type plants comprising modulating the expression in a plant of a nucleic acid encoding a Wall-Associated Kinase-like 14 polypeptide or a homolog thereof, and selecting for plants having increased yield or growth on a nutrient deficient substrate.

  • Publication number: 20060039911
    Abstract: A method for the treatment of gastroesophageal reflux disease comprising a combination of active immunization with an anti-gastrin immunogenic composition with an antagonist that blocks or inhibits gastric acid pump activity; or alternatively administering purified anti-gastrin antibodies with an H2 antagonist or proton pump inhibitor of the gastric acid producing enzyme system.

  • Publication number: 20050187152
    Abstract: Serum-associated hypergastrinemia is treated by administration of gastrin active or passive immunization. An anti-gastrin immunogenic composition containing a gastrin G17 or G34 peptide fragment which is amino acid spacer-linked to an immunogenic carrier, is administered so as to effectively neutralize the circulating gastrin hormone, and moreover, inhibit autocrine activity by progastrin such as Gly-extended G17, and amidated G17, in patients with pernicious anemia. Moreover, the method includes administration of a therapeutically effective amount of anti-G17 or anti-G34 antibodies which may be in humanized form. Finally, the method provides ameliorating treatment of hypergastrinemic effects of proton pump inhibitors or H2 histamine receptor blocking agents or antagonists, in addition to treatment of hypergastrinemia caused by diseases such as pernicious anemia.

  • Publication number: 20050025770
    Abstract: A method of treating gastrointestinal cancers dependent on the prohormones amidated gastrin-17 and glycine extended G-17, comprising the administration to the patient of an anti-gastrin 17 immunogen which induces antibodies which bind and neutralize amidated and glycine-extended gastrin-17.
