HPV associated cancer biomarkers are identified and can be used in a screening method for early stage precancerous lesions as well as late stage cancer progression.

The invention provides cytokine induced killer (CIK) cell populations and methods of using CIK cells to treat cellular proliferative disorders. CIK cells generated in vitro include both bulk cultures and clones. Individual CIK cell clones display distinct but overlapping lytic specificities for tumor cells and endothelial cells in vitro. When injected in vivo, bulk CIK cell cultures selectively attack tumor tissue. CIK cells can be used to treat a variety of cellular proliferative disorders, including early and late stage cancers as well as hematopoietic cell and solid tissue tumors.

Mononoclonal antibodies are used to detect oncogenic high risk and low risk HPV types in a single assay, which is not limited to assay type or format. Useful tools for specific detection of invasive cervical cancer are provided. Cervical cancer biomarkers are identified and can be used in a detection method for early stage precancerous lesions as well as late stage cancer progression.

A method for determining whether early stage cancer is present in a subject comprises detecting the expression level of GASP-1 in the subject by detecting the amount of GASP-1 peptide fragments present in a biological sample of the subject. Because cancer can be detected at an early stage, therapeutic targeting may be initiated before cancer reaches late stage (e.g., before the development of overt symptoms). A method for treating early stage cancer in a subject comprises administering to the subject an effective amount of a GASP-1 inhibitor to inhibit the progression of early stage cancer to late stage cancer. A Competitive ELISA capable of detecting GASP-1 peptide fragments at a concentration of less than 1 ng / ml was developed.

Targeting-enhanced anticancer nanoparticles and preparation methods for the nanoparticles are provided. In particular, this invention provides targeting-enhanced anticancer nanoparticles comprising non-covalently bound anticancer drugs, serum albumins as the nanoparticle base material, and porphyrin compounds as tumor-targeting moieties. The targeting-enhanced anticancer nanoparticles described in the present invention are characterized by non-covalently bound constituents: anticancer drugs, serum albumin as the nanoparticle base material, and porphyrin compounds as tumor-targeting moieties, thus preventing common toxic side effects, enhancing the structural stability of nanoparticles, and enhancing tumor targeting by treatment with electromagnetic waves due to the activity of porphyrin, without structural and functional changes. Taken together, the present invention provides a chemotherapeutic method that maximizes drug delivery / tumor targeting and is expected to be a successful therapy for both early-stage and late-stage cancer.

The present invention provides one kind of conotoxin MVII A and Trx fusion protein and its expression and application. Trx-CTX MVII A fusion protein is first cloned and expressed in colibacillus and then chromatographicaly purified, reduced and oxidized to obtain active Trx-CTX MVII A fusion protein. The obtained fusion protein may be applied in preparing analgetic for late stage cancer and AIDS and that for post-operation pain, burns, etc. and may be also applied in preparing medicine for cerebral ischemia and cerebral demage owing to its nerve protecting function. The present invention can obtain fusion protein with great molecular weight and relatively long half time, and may be applied in medicine development directly or as intermediate to be enzyme incised to obtain active omiga-conotoxin MVII A for further medicine development.

A particle separation multi-membrane matrix device and method are provided. The particles isolated may comprise nano-scale particles, such extracellular membrane vesicles, having a size of about 50 to about 150 nm. The vesicles are released by many different cell types, and may be efficiently isolated at high yield and purity according to the present methods from various body fluids (e.g., blood, saliva, breast milk, serum, plasma, ascites fluid, etc.). Such isolated exosome preparations may include biomarkers, such as disease biomarkers (diagnostic markers) for various disease (early stage and late stage cancers, neurological disorders (Parkinson disease, Alzheimer disease), diabetes, pancreatic diseases, renal failure, infectious diseases (HIV, tuberculosis, malaria, hepatitis)). The present methods and devices may be used to detect and monitor animals (human, livestock, companion animal) for infectious diseases, such as tuberculosis and other diseases. The methods and devices require minimal sample material (10 μl), are rapid, economical, yield highly enriched small molecule (eg, exosomes) preparations, and do not require electricity.
