  • Patent number: 12029730
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating cancer, a radiosensitizer composition for treating cancer, and a health functional food for preventing or improving cancer, which comprise N-1H-benzimidazol-2-yl-3-(1H-pyrrol-1-yl) benzamide, a derivative thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The pharmaceutical composition comprising N-1H-benzimidazol-2-yl-3-(1H-pyrrol-1-yl) benzamide or a derivative thereof as an active ingredient according to the present invention arrests the mitosis of cancer cells to prevent proliferation and at the same time, to exhibit low toxicity in normal cell lines and induce apoptosis only in cancer cell lines, so it can be used as an effective anticancer agent. In addition, the N-1H-benzimidazol-2-yl-3-(1H-pyrrol-1-yl) benzamide of the present invention can increase the sensitivity of the treated cancer cells to radiation, so it can be used as a radiosensitizer composition for cancer treatment.

  • Publication number: 20230099264
    Abstract: The present invention provides a method for providing information for diagnosis of metastasis of radiotherapy-treated lung cancer, the method comprising the steps of: (a) measuring an expression level of receptor-interacting protein kinase 1 (RIP1) in a sample from a lung cancer patient who has undergone radiotherapy; (b) measuring an expression level of RIP1 in a normal control sample; and (c) comparing the expression levels of step (a) and step (b).

  • Patent number: 9963701
    Abstract: The present invention relates to a pharmaceutical composition for treating a radiation- or drug-resistant cancer, containing an agent capable of inhibiting the expression of hepatoma-derived growth factor (HDGF)-related protein-3 (HRP-3), a method of treating a radiation- or drug-resistant cancer by administering the pharmaceutical composition, and the use of an HRP-3 inhibitor for preparing an agent for treating a radiation- or drug-resistant cancer. The use of the pharmaceutical composition of the present invention enables to treat a resistant cancer in combination with a conventional anticancer chemotherapy or radiotherapy. Accordingly, the pharmaceutical composition of the present invention can reduce both the costs for developing anticancer agents against resistant cancers and the costs for treating cancers in patients, thus being useful for the economic and effective treatment of resistant cancers.

  • Patent number: 9588119
    Abstract: Disclosed are increased expression of ERp57, ERp57-STAT3 complex, and ERp57-STAT3-Mcl-1 in laryngeal cancer, especially in radioresistant laryngeal cancer and their regulations on radioresistance of laryngeal cancer. As such, the efficacy of radiotherapy can be enhanced by diagnosing prognosis in laryngeal cancer and radioresistance of laryngeal cancer. Furthermore, provided are a method of screening a therapeutic agent for laryngeal cancer including selecting a candidate drug that inhibits the expression of ERp57 or inactivates ERp57, and a therapeutic method for inhibiting or treating laryngeal cancer or radioresistant laryngeal cancer, thereby being useful in the treatment of laryngeal cancer.

  • Publication number: 20120034235
    Abstract: A composition for detecting a marker for the diagnosis or prognosis of liver cancer is disclosed. The composition includes an agent capable of assessing the expression level of UQCRH (ubiquinol-cytochrome c reductase hinge protein). In addition, a kit having the composition, a microarray for the diagnosis of liver cancer using the marker, and a method for detecting the marker, and predicting recurrence following surgery in liver cancer patients are disclosed. The marker is able to contribute to the early diagnosis of liver cancer and prediction of recurrence following surgery and survival of liver cancer patients who have undergone hepatic resection, and also is significant for being a promising therapeutic target for liver cancer.
