Lipoxygenase Proteins and Nucleic Acids

Isolated and purified lipoxygenase proteins and nucleic acids are described. Particularly, a novel human 15(S) lipoxygenase (15-Lox-2) protein and cDNA and a cDNA for mouse 8S-lipoxygenase are described. Recombinant host cells, recombinant nucleic acids and recombinant proteins are also described, along with methods of producing each. Isolated and purified antibodies to 15-Lox-2 and 8-Lox, and methods of producing the same, are also described.

Guava (Psidium Guajava) 13-Hydroperoxide Lyase and Uses Thereof

This invention relates to fatty acid 13-hydroperoxide lyase protein from guava (Psidium guajava) and the gene encoding the protein. Expression systems for recombinant guava 13-hydroperoxide lyase and methods of using recombinant guava 13-hydroperoxide lyase for the production of green notes are provided.

BMP-15 Compositions

Purified BMP-15-related proteins and processes for producing them are disclosed. DNA molecules encoding the BMP-15-related proteins are also disclosed. The proteins may be used in the treatment of bone and cartilage and/or other connective tissue defects and in wound healing and related tissue repair.

Nuclear Targeting Peptide Nucleic Acid (PNA)

A composition comprising a nuclear localization sequence and a peptide nucleic acid oligomer (NLS-PNA) is described. Uses of the composition include, but are not limited to: regulation of gene expression, gene therapy, and the production of pharmaceutical nucleic acids and proteins. In addition, the NLS-PNA is useful for scientific and therapeutic transfection and expression of nucleic acids in cells types that previously were resistant to transfection and therapy including quiescent cells, differentiated cells, embryonic stem cells, and eukaryotic cells with intact nuclear membranes. The NLS-PNA can be combined with a membrane transport sequence (MTS) forming a novel compound referred to as an MTS-NLS-PNA wherein the MTS provides transport through the cytoplasmic membrane of a cell. A nuclear targeted peptide nucleic acid oligomer is useful for the treatment of genetic based diseases and diseases that can be treated genetically including heart disease, cancer, cerebrovascular diseases, chronic pulmonary diseases, human immunodeficiency virus, and other diseases, conditions and disorders.

Analysis of Paralinguistic Properties of Speech for Near-term Suicidal Risk Assessment

Method and apparatus to measure jitter (period-to-period fluctuations in fundamental frequency) among the voices of suicidal, major depressed, and non-suicidal patients to predict near-term suicidal risk.

A Method for Genetically Engineering Proteins with Cell Membrane Translocating Activity

The invention describes a membrane-translocating peptide sequence (MTS) which facilitates entry of polypeptides and proteins into cells. Also described is an isolated nucleotide sequence encoding the membrane-translocating peptide and a method of using this sequence to genetically engineer proteins with cell membrane permeability. The MTS, and the method of genetically engineering proteins with cell membrane permeability, are useful for polypeptide and protein delivery for human and veterinary applications such as vaccine delivery and cancer therapy.

Ligation of Side-Chain Unprotected Peptides

A method of chemical ligation of peptides that requires no side chain protecting groups and no activation of the C-.alpha. carboxyl group is presented. The method consists of three steps. In the first step, initiation, a masked glycoaldehyde ester is enzymatically or chemically coupled to the C-terminal carboxylic acid of an sidechain unprotected first peptide. In the second step, ring formation, the masked aldehyde ester of the first peptide is unmasked, and then reacted with the N-.alpha. amino acid of a second sidechain unprotected peptide to form a ring structure. In the third step, rearrangement, the O-acyl ester linkage transfers at higher pH to an N-acyl linkage on the ring to form a peptide bond.

Methods of Purifying and Differentiating Spermatogonial Stem Cells

The invention relates to cell proliferation, cell differentiation, male infertility, male fertility and to compositions and methods involved therein. Also methods of culturing spermatogonial stem cells with bone morphogenetic protein 8 are disclosed.

Assay for Novel Serotonin Transporter Blockers

The mutant SERTs we have developed can provide for a platform to screen for novel modes/molecules interrupting SERT function. As SERT blockers are effective antidepressants, this strategy can lead to novel antidepressant medications. It may also be useful in development of animal models to test antidepressant action in vivo.

MMP-7 Null Mice

The only MMP-7-null mouse that has been generated. Used to determine biological function of MMP-7. Mice have been used in more than 10 publications at this point, and will be distributed by a commercial vendor in the near future.

Method for Regulation of DNA and RNA Transcription and Translation

Vanderbilt researchers have discovered and patented a means of selectively expressing genes of interest in specific cells. This research tool allows an inactive nucleic acid to be delivered to a specific cell of interest and then the researcher can activate the nucleic acid by exposure to light. This system allows temporal controlled expression over exogenous nucleic acids only in targeted cells or selectively regulating endogenous gene expression.

Heterologous Expression System for Studying Recombinant Human Brain Voltage-Gated Sodium Channel, SCN1A

Isolated nucleic acids encoding human SCN1A polypeptides, recombinantly expressed and isolated human SCN1A polypeptides, heterologous expression systems for recombinant expression of human SCN1A polypeptides, assay methods employing the same, and methods and compositions for modulation of sodium channel function.
