    Abstract: The present invention provides for identification of agents that induce growth arrest and survival of cancer cells, which remain dormant in bone marrow, thus preventing their eradication through use of standard chemotherapy or radiation therapy. Basic fibroblast growth factor (FGF-2), a mammary differentiation factor abundant in the bone marrow stroma, induces growth arrest of relatively differentiated breast cancer cells and restricts their survival to fibronectin by upregulating integrin α5β 1. Most of the FGF-2-arrested cells fail to establish optimal ligation to fibronectin and undergo cell death. Cells that do attach to fibronectin, another major constituent of the bone marrow microenvironment, stay alive and growth-arrested for many weeks. Using function-blocking antibodies and peptides, a specific contribution of α5β1-fibronectin interaction in maintaining survival of growth-arrested cells was demonstrated. The present invention thus allows for methods, agents and pharmaceutical compositions that can be used to potentiate the activity of chemotherapy or radiation therapy.

    Abstract: A method for treating pulmonary hypertension and other diseases involving a defect in collagen metabolism, by administration of an effective amount of a liposome encapsulated copolymer conjugate antifibrotic composition, is disclosed. The antifibrotic agent is preferably proline analogs, such as cis-4-hydroxy-L-proline (CHOP), 3,4-dehydro-DL-proline (DHP), (R)-(-)-2-thiazolidine-4-carboxylic acid (THP), and (S)-(-)-2-azetidinecarboxylic acid (ACA). Consistent, high loadings (>90%) of the antifibrotic agent are achieved by first forming a dipeptide with L-lysine, after which the dipeptide is copolymerized with the polymer component to form the copolymer conjugate. The polymer is preferably poly(ethylene glycol) having a weight average molecular weight of from about 500 to about 15,000. Efficient delivery and consistent release of the antifibrotic agent inhibits collagen accumulation and treats the diseases involved. Accordingly, there is a substantial reduction in the quantity of antifibrotic agent necessary, and thus a corresponding reduction in the potential for toxicity that would otherwise result from its prolonged administration.

    Abstract: The present invention discloses a novel single nucleotide polymorphism (SNP) in the isolated 5' tandem repeats of the thymidylate synthase (TS) gene and methods for its use. The novel SNP, located in the 12th nucleotide of a 28 bp third tandem repeat (3R) of the TS gene, substitutes a C for a G, and is the variant form of the repeat. Subjects with the wild-type form of 3R have greater transcription of the TS gene than subjects with the variant form. The invention also reveals that a six base pair deletion in the 3' region of TS (-6 bp/1494) indicates mRNA instability and thus reduced production of TS. In diseased tissue, such as cancer, reduced production of TS is beneficial because it prevents the cancerous cells from growing and spreading. Analysis of either polymorphism or both together allows for prediction of a subject's response to chemotherapeutic and anti-cardiovascular disease treatments because both diseases are related to TS levels in a subject.
