  • Publication number: 20160039923
    Abstract: Granulin-epithelin precursor (GEP), a pluripotent growth factor, is a hepatic oncofetal protein defining a cancer stem cell (CSC) population in liver cancer. The present invention provides the use of GEP inhibitors (including anti-GEP antibody) for inhibiting immune evasion by liver cancer cells and for eliminating liver cancer stem cells.

  • Patent number: 9207242
    Abstract: Compositions and methods for diagnosing, treating and/or preventing cancers characterized by CDH17 overexpression based on the detection of CDH17 or the use of CDH17 as a target for therapeutic intervention or prophylactic intervention are provided. Methods for diagnosing and/or monitoring liver cancers using the expressing of CDH17 involve detecting and/or quantitating the CDH17 protein or encoding nucleic acids (DNA or RNA) in a biological sample such as urine from the subject. Methods for treating liver cancers using CDH17 as a target and of sensitizing cells with aberrant expression of CDH17 have also been developed. The methods include suppression or knockdown of the expression of CDH17 by administering an effective amount of a CDH17 inhibitor.

  • Publication number: 20110280862
    Abstract: Described herein are methods for manipulating GEP and/or drug transporters (e.g., ABCB5 and/or ABCF1) on a cell, as well as related products. Also described herein are methods for treating cancer cells using GEP and/or drug transporter and/or their binding molecules and suppression thereof. Methods of cancer treatment targeting the GEP and/or drug transporters, alone or in combination with chemotherapy are also described herein. Also provided herein are sets of markers whose expression patterns can be used to differentiate clinical conditions, such as high or low levels of GEP and drug transporters. Based on the levels of GEP and drug transporters, the likelihood of cancer recurrences, drug sensitivity, and prognosis can be determined. Methods of classifying and treating patients based on the prognosis are also provided herein.

  • Patent number: 7960338
    Abstract: Bacterial lipopolysaccharide (LPS) in systemic circulation triggers deleterious super-inflammatory response, which is key pathogenesis of many disorders like gram-negative sepsis and necrotizing enterocolitis. No effective therapeutic interventions are currently available for protection of patients against mortality. Disclosed are methods and therapeutic agents that ablate the biological toxicity of LPS in circulation (Integrin Peptide), and abrogate leukocyte infiltration into lung and liver and suppress adhesion molecule expression (Integrin Peptide and Anti-CD18 ?A scFv). These therapeutic agents can be used alone, or in combination for treatment of endotoxin-mediated pro-inflammatory responses, particularly in cases of acute sepsis and necrotizing enterocolitis.
