Abstract

The present invention relates to exosomes comprising an miRNA pool based on the inhibition of TGF-β signaling involved in cancer growth and metastasis. The exosomes, which are derived from tripartite motif containing 40 (TRIM40) transformed cells treated with staurosporine, comprise a pool of miRNAs that inhibit the expression of ECM- and EMT-related genes, the miRNAs include miR-1343-3p (which inhibits the expression of TGBR1 and TGFBR2), miR-4285 (which inhibits the expression of the TGFB1 gene), and miR-194-3p (which inhibits the TGF-beta signaling pathway), which inhibit the TGF-beta signaling pathway in cancer cells, thereby comprehensively blocking the expression of EMT- and ECM-related genes by surpassing a one-dimensional method of loading one specific miRNA or a small molecule that exhibits anticancer activity so as to inhibit TGF-beta signaling pathways when the miRNAs are absorbed and delivered into cancer cells, and thus the cancer microenvironment is modulated such that strong anticancer responses can be induced in preclinical settings.

Abstract

The present invention relates to an autoimmune disease animal model and a method for preparing the same. The animal model of the present invention efficiently generates an autoantibody that causes autoimmune disease, by introducing an autoantigen-encoding gene through the Cre-LoxP system, which enables stable and continuous expression of the autoantigen at a desired time by treatment of Cre recombinase. Contrary to the conventional method that fails to effectively produce autoantibody due to leaky expression and immune tolerance, or requires repeated administration over several weeks, the present invention achieves sustainable expression of an effective amount of autoantigen by only one TAT-Cre recombinase treatment, thus may be utilized as an outstanding animal model reproducing various symptoms and molecular mechanisms of autoimmune diseases.

The present invention relates to a composition for prevention or treatment of inflammatory or autoimmune skin diseases. The composition of the present invention may be useful as a fundamental therapeutic composition that is able to efficiently ameliorate skin tissue damage caused by inflammation while having a minimized impact on systemic immune activity by specifically inhibiting the activity of skin-specific T cells. In addition, the composition of the present invention may be efficiently delivered to the stratum corneum of the skin, so that it is able to exert a lesion-specific and intensive immune control effect as a composition for topical application to the skin. Moreover, it shows little toxicity to normal skin tissue, and thus is suitable even for long-term administration for the treatment of atopic dermatitis, a chronic disease. The present invention also provides, based on the newly identified correlation between skin-specific T cells and PIK3CD protein, a screening method capable of quickly and highly reliably identifying promising therapeutic candidates that are able to alleviate various autoimmune and inflammatory damages occurring in skin tissue.

Abstract

The present invention relates to a nucleic acid construct that can express and inhibit a gene simultaneously.

Accordingly, a protein to be expressed may be expressed normally while expression of a particular gene may be specifically inhibited. The mRNA-siRNA nucleic acid construct activates an immune system by expressing a target protein in an antigen-presenting cell, and at the same time, overcomes interference of immune escape by blocking the activity of an immune checkpoint protein, and thus is expected to be remarkably useful in the fields of immunotherapy, especially in the field of cancer immunotherapy.

Abstract

The present invention relates to a composition for diagnosing endometriosis, the composition comprising an agent for measuring the level of miRNA as an active ingredient. The present invention was developed in an effort to overcome the conventional diagnostic difficulties and treatment limitations associated with endometriosis. As a result, during the search for new diagnostic targets in endometrial cells isolated from healthy controls and patients with endometriosis, a difference in the expression of miRNA within exosomes was identified. It was found that the expression of miRNA within exosomes isolated from patients with endometriosis significantly increased or decreased compared to healthy controls, leading to the completion of the present invention. The composition can be advantageously utilized as a diagnostic and therapeutic agent for endometriosis.

Abstract

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths worldwide, but lacks effective prognostic indicators. Methionyl-tRNA synthetase 1 (MARS1), which is an important enzyme in translation initiation for delivering Met to initiator tRNA, is associated with cancer development and progression. MARS1 expression was found to significantly increase in PDAC compared to normal pancreatic duct tissue. In addition, the high expression of MARS1 was found to be associated with poor prognosis in PDAC patients. This suggests that MARS1 is involved in pancreatic carcinogenesis and has potential as a novel prognostic indicator for PDAC.

Abstract

The present invention relates to a method for predicting the response to immunotherapeutic agents, comprising a step of measuring, in cancer cells or cancer tissue, the expression level of a dexamethasone-induced ras-related protein 1 (Dexras 1) gene or a protein encoded thereby. According to the present invention, research has been carried for prediction of the response to immunotherapeutic agents and, particularly, research has been carried out for prediction of the response to immunotherapeutic agents, highly reliable therapeutic agents and effective diagnosis of stem cell-like gastric cancer, which has the poorest prognosis and for which discovery of an effective treatment and diagnosis is difficult. As a result, it has been identified that in refractory carcinoma, the expression of Dexras 1 is high and, when an immunotherapeutic agent is injected, resistance to the immunotherapeutic agent is exhibited. In addition, changes in the expression level of Dexras 1 in cancer samples are measured such that immunotherapeutic agents for refractory cancer, such as stem cell-like gastric cancer that is difficult to be treated, are provided and refractory cancer can be diagnosed, and the response to anticancer immunotherapeutic agents for effective immunotherapy can be predicted such that the present invention has been completed. Therefore, the present invention is expected to be widely used in the development of novel therapeutic agents for refractory cancer.
