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.
Scientists at Vanderbilt have developed a unique polypeptide using cell-penetrating SOCS polypeptides or SOCS sequences designed to inhibits cytokine signaling and thus prevent or treat inflammation or an inflammatory related disease such as diabetes. This strategy has been validated in NOD mice models for either induced or naturally occurring diabetes and have been efficacious.
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.
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.
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.
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.
Therapeutic methods for the treatment of prostate cancer are described. The methods include a gene therapy method for prostate cancer using the BRCA family of genes, including the BRCA1 and BRCA2 genes. The BRCA family of gene products inhibit the growth and tumorigenesis of prostate cancer cells. Therapeutic methods using the BRCA family of gene products are also described.
In accordance with the present invention, there are provided amphiphilic polyamine compounds and derivatives thereof having the property of promoting transfection of polynucleotides and polypeptides into cells, and formulations comprising said compounds.
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.
A novel method of treating human diseases using natural products found in roasted coffee. The use of natural products or derivatives thereof would permit the general public to improve their health without having to use prescription drugs.
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.
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.
