Suppression of malignant mesothelioma by overexpression or stimulation of endothelial protein C receptors (EPCR)
The influence of TF, endothelial cell protein C receptor (EPCR) and protease activated receptor-1 (PAR1) on tumor growth of malignant pleural mesothelioma (MPM) is disclosed. MPM cells that lack or express TF, EPCR or PAR1 and a murine orthotopic model of MPM led to the discovery that intrapleural administration into nude mice of REN MPM cells expressing TF and PAR1 but lacking EPCR and PAR2 generated large pleural cavity tumors. Suppression of TF or PAR1 expression markedly reduced tumor growth. Overexpression of TF in non-aggressive MPM cells expressing EPCR and PAR1 but exhibiting minimal levels of TF failed to alter their tumorigenicity. Introduction of EPCR expression in aggressive MPM cells attenuated tumor growth whereas EPCR silencing in non-aggressive MPM cells overexpressing TF increased tumorigenicity of non-aggressive cells. Expression of EPCR by MPM cells suppresses tumor growth and treats MPM.
COEXPRESSION PLASMID
The object of the invention is to provide an anaerobic enterobacterium having a higher therapeutic effect on an anaerobic site such as a solid tumor tissue and an ischemic disease site. A bacterium of the genus Bifidobacterium, which is transformed with a plasmid co-expressing two types of heterologous polypeptides and comprising two types of secretory expression cassettes each sequentially comprising a promoter DNA functioning in the bacterium of the genus Bifidobacterium; a DNA encoding a secretory signal peptide; a DNA encoding a heterologous polypeptide; and a terminator DNA functioning in the bacterium of the genus Bifidobacterium, efficiently secretes the two types of heterologous peptides, i.e., two types of antibodies having anticancer effects, outside the bacterial cell.
Bioactive compositions derivable from platelet concentrates, and methods for preparing and using same
The present disclosure provides a composition comprising a bioactive fraction derived from a platelet concentrate, methods of making the bioactive fraction, and culture medium supplemented with the bioactive fraction. Preferred bioactive fractions have relatively low fibrinogen concentrations while retaining native growth factors in beneficial amounts and ratios.
METHODS OF TREATMENT AND RELATED COMPOSITIONS
The present invention relates to methods of treating a disease characterised by aberrant cell proliferation (e.g., a cancer) in a human subject in need thereof. In particular, the present invention relates to treating the above conditions by administering a therapeutically effective amount of at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon, and administering to the subject at least one agent that inhibits the Hedgehog (Hh) signalling pathway (e.g., Vismodegib). Also provided are pharmaceutical compositions, including controlled release pharmaceutical compositions, containing at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon (e.g., a checkpoint inhibitor), an inhibitor of Hh signalling pathway, and a controlled release matrix such as a SiO.sub.2 matrix gel.

CELL-FREE COMPOSITIONS AND METHODS FOR RESTORATION OR ENHANCEMENT OF TISSUE FUNCTION
Cell-free compositions for promoting restoration of tissue function or enhancement of tissue function and methods of stimulating or promoting restoration or enhancement of tissue function using the cell-free compositions. The compositions herein help stimulate endogenous pathways via a subject's own cells effectively for improving tissue function, enhancing tissue function, enhancing cell proliferation, etc. The compositions comprise one or a plurality of therapeutic components such as growth factors, extracellular matrix, DNA, RNA, hormones, drugs, cell surface receptors, enzymes, cytokines, angiogenesis modulating factors, etc., e.g., any material that can effectively activation endogenous pathways in the subject's own cell to a desired effect. The cell-free composition comprises a carrier or is attached to or integrated into and/or within a carrier. The carrier may help provide for containment of the therapeutic components and/or provide for time-release of the therapeutic components of the cell-free composition.
