The method for detecting metastatic breast, gastric, pancreas or colon cancer cells in paraffin-embedded samples utilizes panels of markers selected from a group consisting of C-Met, MAGE-A3, Stanniocalcin-1, mammoglobin, HSP27, GalNAcT, CK20, and β-HCG.

Provided are methods for intra-operatively predicting, detecting or diagnosing the risk or onset of spinal cord ischemia and / or associated permanent paralysis in a patient, based upon the stress-induced elevation of levels of heat shock proteins, specifically HSP70 and / or HSP27 in the cerebral spinal fluid of the patient, as measured during thoracic-aorta surgery, particularly thoracic aneurysm repair surgery, that will permit intra-operative medical intervention to try to prevent or attenuate severe, and often fatal, complications. Further provided are kits, assay devices and methods of analyzing biomarker data for use in pre-, intra- or post-operatively detecting the stress-induced elevations of the measured levels of HSP70 and / or HSP27, and the biomarker itself.

Also disclosed are kits containing agents for detecting the expression of these genes.

The subject invention concerns materials and methods for treating neurodegenerative diseases and conditions associated with aggregation of the microtubule-associated protein tau. A method of the invention comprises administering an effective amount of a heat shock protein 27 (Hsp27), or a biologically-active fragment or variant thereof, or a polynucleotide encoding the same, to a person or animal in need of treatment. In one embodiment, a heat shock protein 27 (Hsp27), or a biologically-active fragment or variant thereof, is contacted with or provided to a target cell. The target cell can be a neuron. In a specific embodiment, an Hsp27 is delivered to the target cell via a polynucleotide encoding an Hsp27 protein, or a biologically-active fragment or variant thereof. In one embodiment, a method of the invention comprises injecting (e.g., via stereotaxic injection) a polynucleotide expression construct of the invention comprising a polynucleotide encoding an Hsp27 protein directly into neural tissue of a person or animal. The subject invention also concerns compositions comprising i) a heat shock protein 27, or a biologically-active fragment or variant thereof, and / or ii) a polynucleotide encoding an Hsp27, or a biologically-active fragment or variant thereof. The polynucleotide can be an expression construct that provides for expression of an Hsp27 in a target cell.

Therapeutic agents which target heat shock protein (hsp) 27 in vivo are used to provide treatment to individuals, particularly human individuals, suffering from prostate cancer and other cancers that overexpress hsp27. A therapeutic agent, for example an antisense oligonucleotide or RNAi nucleotide inhibitor with sequence specificity for hsp27 mRNA, for example human hsp27 mRNA, is administered to an individual suffering from prostate cancer or some other cancer expressing elevated levels of hsp 27 in a therapeutically effective amount. The therapeutic agent is suitably formulated into a pharmaceutical composition which includes a pharmaceutically acceptable carrier, and packaged in dosage unit form. A preferred dosage unit form is an injectable dosage unit form.

The invention discloses recombinant fusion protein PTP-HSP27 and use thereof; an amino acid sequence is SEQ ID NO.1; the recombinant fusion protein PTP-HSP27 disclosed by the invention not only has the biological activity of HSP27, but also has a transcellular barrier transportation function; the recombinant fusion protein PTP-HSP27 can effectively perforate into lenticular epithelial cells (LEC); the apoptosis of the lenticular epithelial cells is alleviated; and the development and progression of cataract is delayed greatly. According to the invention, the recombinant fusion protein PTP-HSP27 endows the transcellular barrier transportation function of PTD to the HSP27, thus, the HSP27 easily perforates the cell barrier of corneas and effectively enters eyes through cornea tissues; and the application range of the recombinant fusion protein PTD-HSP27 in an eye part is expanded.

The present invention relates to a HSP27 mutation (S135F) mediated Charcot-Marie-Tooth disease (CMT) animal model. Particularly, the vector expressing mutant HSP27 protein wherein the 135th serine is substituted with phenylalanine has been injected in the mouse zygote and then the mouse harboring the expression vector was selected. The selected mouse was confirmed to display Charcot-Marie-Tooth disease phenotype, so that the animal model was expected to be efficiently used for the evaluation of the effect of Charcot-Marie-Tooth disease treating material candidates.

A method for detection or monitoring status of traumatic brain injury (TBI) or spinal cord injury (SCI) in a subject is provided. In one embodiment, the method comprises contacting a specimen of bodily fluid obtained from the subject with reagents for assaying for a marker of TBI selected from aldolase C (ALDOC) and brain lipid binding protein (BLBP), or a trauma-specific break down product (BDP) of ALDOC or BLBP. The method further comprises measuring the amount of marker present in the specimen as compared to a control sample, and determining the presence of TBI or SCI when an elevated amount of marker is present in the specimen compared to the control sample. The method can comprises measuring the amount of glutamine synthetase (GS), astrocytic phosphoprotein PEA-15 (PEA15), αB-crystallin (CRYAB / HSP27), a cleavage product of ALDOC, GS, PEA15, or CRYAB, or a combination of two or more thereof.

A composition for prevention or treatment of pulmonary fibrosis comprising chromenone derivatives represented by Formula I of the present invention or pharmaceutically acceptable salts thereof as an active ingredient, produces altered heat shock protein 27 (HSP27) dimers, thereby preventing normal HSP27 non-phosphorylated polymers from performing a chaperone function and reducing a cell protection function that chaperone originally performs. Thus the inventive composition has a remarkable inhibitory effect on pulmonary fibrosis, in particular, an irradiation-induced pulmonary fibrosis phenomenon.
