摘要:
The p21 gene encodes a cyclin dependent kinase inhibitor which affects cell cycle progression, but the role of this gene product in altering tumor growth has not been established. The present inventors have now discovered that the growth of malignant cells in vivo is inhibited by expression of p21. Expression of p21 resulted in an accumulation of cells in G0/G1, alteration in morphology, and cell differentiation.

摘要:
A method for the direct treatment towards the specific sites of a disease is disclosed. This method is based on the delivery of proteins by catheterization to discrete blood vessel segments using genetically modified or normal cells or other vector systems. Endothelial cells expressing recombinant therapeutic agent or diagnostic proteins are situated on the walls of the blood vessel or in the tissue perfused by the vessel in a patient. This technique, provides for the transfer of cells or vectors and expression of recombinant genes in vivo and allows the introduction of proteins of therapeutic or diagnostic value for the treatment of diseases.
摘要:
The invention provides insight into the function of Protein Arginine N-Methyltransferase-2 (PRMT-2) and provides methods for modulating PRMT-2 activity or expression in cells. The methods of the invention can be used to inhibit the function of NFκB, E2F1 and STAT3 and have utility for treating a variety of conditions including, for example, inflammation, HIV infection, cancer and obesity.
摘要:
Disclosed herein are novel composition and methods for altering the proliferation of a cell. Included are wild-type and mutant hKIS polypeptides along with cyclin kinase inhibitors containing mutations that prevent their inhibition with serine/threonine kinases.

摘要:
The invention relates to fusion proteins useful in delivering a targeted nucleic acid to a target cell, comprising a gene delivery fusion protein (GDFP), said GDFP comprising a nucleic acid binding domain (NBD) that binds to the targeted nucleic acid, fused to a gene delivery domain (GDD) that mediates delivery of the targeted nucleic acid to the target cell, wherein said GDD comprises one or more components that facilitate delivery of a targeted nucleic acid to a target cell, and wherein one of said components is a transport/localization component and wherein said transport/localization component is an adenovirus protein V or derivative thereof that retains protein V activity, and related methods of making and using thereof.
摘要:
The present disclosure relates to stabilized forms of the HIV gp120 envelope protein in complex with the broadly neutralizing CD4-binding site antibody b12, to crystalline forms of the stabilized forms of the HIV gp120 envelope protein in complex with the broadly neutralizing CD4-binding site antibody b12, and to the high resolution structure obtained from these crystals by X-ray diffraction methods. Methods for identifying immunogenic polypeptides based on these structures are also disclosed.
