Abstract: The present invention provides methods for modulating the growth and/or yield of plants. In particular the methods comprise the use of agents which functionally inhibit the expression of plant D-like cyclin inhibitors including isolated polynucleotide sequences which interact with DNA or RNA encoding proteins capable of binding plant D-like cyclins. Further, the present invention provides recombinant polynucleotide sequences, vectors and host cells which encode proteins capable of binding to and inactivating the activity of plant D-like cyclin/cyclin dependent kinase complexes preventing plant cells from exiting the cell cycle. Methods for determining and agents which are inhibitors of the BRO cyclin dependent kinase inhibitor proteins which are capable of modulating plant cell cycle progression are also provided. Methods for the production of transgenic plant cells and plants with increased growth rates and yields when compared to wild-type plants are also provided.

Abstract: Hypercellular nonhuman organisms have functionally inactivated expression of a cyclin inhibitor gene, especially p27. The growth rate of nonhuman organisms are increased such that a desired size is attained more quickly than as compared to nonvariant organisms. Inhibitors of the p27 cyclin dependent kinase inhibitor protein or sequences encoding the protein modulate vertebrate cell cycle progression and increase the proportion of dividing cells to non-dividing cells in a population of treated cells. As the proportion of dividing cells increases, the cell population, e.g., hematopoietic progenitor (stem) cells, is more efficiently used for gene therapy applications. Transgenic animals and plants, and knockout alleles are provided.

Abstract: Whole cell or cell-free test systems for screening and identifying compounds that modulate or alter Cyclin E activity. Whole cell assays measure the G1 phase of cells in the presence or absence of the test compound. Additional whole cell or cell-free assays measure binding of cyclin E to a cell division kinase, measure cyclin E activity directly, or measure the cell division kinase activity directly in the presence or absence of the test compound.

Abstract: This invention relates to the diagnosis of preeclampsia using an assay to measure a mitogenic factor in blood. Preeclampsia is a serious problem in pregnant women. It is an idiopathic life threatening hypertensive condition. The condition of preeclamptic women can often deteriorate to a point where serious injury will occur to either the mother, child or both. Preeclampsia is a leading cause of death both maternal and infant.

Abstract: Multiple copies of a foreign DNA I coding for the production of a protein may be introduced into eucaryotic cells by cotransforming suitable cells with foreign DNA I and with foreign DNA II which includes a functionally deficient, amplifiable gene coding for a selectable or identifiable trait, preferably carried on the same DNA molecule as a foreign DNA III, which includes a functional, amplifiable gene coding for another selectable or identifiable trait. The cotransformation is carried out under suitable conditions permitting selection or identification of cells expressing the gene on DNA I or that on DNA III, but not that on DNA II. The cotransformed cells so identified or selected are recovered and cloned under conditions where the functionally deficient gene on DNA II is expressed. Cells expressing the gene on DNA II are recovered. They contain multiple copies of DNA I. This method can be used to produce mRNA transcripts or protein products such as human and animal growth hormone, insulin and the like.

Abstract: A coin game which is played on a game board having thereon a multiplicity of individualized landing spaces along the game board path. Each landing space has a specific designation. Along the path, are general landing squares, each representing one of a set of 24 Peace Dollar Series coins. Other landing squares are action squares wherein a player has the option of buying or selling coins, buying or selling silver shares or gold shares, or receiving money. The object of the game is to either collect the entire 24 Peace Dollar Series of coins or alternatively accumulate a sufficient amount of cash so that the player can acquire the rare 1927-D $20 St. Gaudin gold coin for $150,000. The game pits players against each other. Each player is given a certain amount of cash at the start of the game and a playing piece to move along the game board. The game is educational in that it teaches the player about coins and coin collecting and is also a game of both chance and skill.
