摘要:
Isolated and/or recombinant nucleic acids encoding mycobacterial methionyl-tRNA synthetase have been characterized. Recombinant DNA constructs and vectors having a sequence which encodes mycobacterial methionyl-tRNA synthetase have been made, and can be used for the construction of tester strains as well as for the production of isolated and/or recombinant methionyl-tRNA synthetases. These enzymes or portions thereof are useful in the biochemical separation of methionine and quantification of methionine or ATP, and for producing antibodies useful in the purification and study of the enzyme, for example. Host cells and methods useful for producing recombinant mycobacterial methionyl-tRNA synthetases are described, as are tester strains, which are cells engineered to rely on the function of the tRNA synthetase encoded by an introduced cloned gene. Tester strains can be used to identify inhibitors of the essential tRNA synthetase enzyme encoded by the introduced cloned gene, and thus provide a means to assess the antimicrobial effect and specificity of the inhibitor without employing slow-growing, pathogenic strains of mycobacteria, such as Mycobacterium tuberculosis.
摘要:
This application relates to a novel benzo-heterocycle derivative and more particularly, it relates a composition for preventing and treating cancer or for inhibiting metastasis comprising benzo-heterocycle derivative or pharmaceutically acceptable salts thereof as an active ingredient. The present inventors confirmed that KRS has an effect on cancer metastasis by facilitating cancer (or tumor) cell migration through interaction with 67LR, and also found that a substance inhibiting the interaction between KRS and 67LR can prevent and treat cancer by inhibiting cancer cell metastasis. Accordingly, the composition of the present invention can inhibit cancer metastasis, and thus provide a novel means for prevention and treatment of cancer.

A three-dimensional semiconductor device includes a semiconductor substrate including a cell array region and a peripheral circuit region, an electrode structure including electrodes vertically stacked on the cell array region, a MOS capacitor on the peripheral circuit region, an interlayer dielectric layer covering the electrode structure and the MOS capacitor, first and second power lines spaced apart from each other in a first direction and extending in a second direction on the interlayer dielectric layer, first lower plugs connected to the first power line and a first terminal of the MOS capacitor, and second lower plugs connected to the second power line to a second terminal of the MOS capacitor. The second power line is on one of the first lower plugs that is adjacent to some of the second lower plugs in one of the first and second directions.
摘要:
Pleural empyema removal devices are provided and enable the removal of empyema from the pleural cavity of a human or veterinary patient. The pleural empyema removal devices may be coupled with one or more additional devices, such as suction source, gas source, light source and/or camera source, and monitor. The devices and systems including the devices facilitate the removal of empyema from the pleural cavity of a patient while providing protections from damage to untargeted tissues. The devices, systems, and methods can be used in the treatment process to treat pleural empyema resulting from pleural effusions and infections stemming from various illnesses and disorders, such as pneumonia.
摘要:
The present invention provides, as a novel diagnosis marker for type 1 diabetes mellitus, a type 1 diabetes mellitus diagnostic composition comprising alanyl-tRNA synthetase, glycyl-tRNA synthetase, asparaginyl-tRNA synthetase, or tryptophanyl-tRNA synthetase, a diagnostic kit comprising the same, and a diagnostic method using the same. The composition, the kit, and the method, according to the present invention, may be used for early diagnosis and confirmed diagnosis of type 1 diabetes mellitus because type 1 diabetes mellitus can be easily diagnosed from a patient sample.
摘要:
The present invention relates to novel 2,4-pyrimidine derivatives and a use thereof, and more particularly, to pyrimidine derivatives which are effective for systemic lupus erythematosus, a composition for preventing and treating systemic lupus erythematosus comprising the same as an active ingredient and a method for screening the same. The present inventors found novel materials inhibiting surface translocation of gp96 by mimicking a function of AIMP1 which is a molecular anchor for an intracellular residence of gp96, and identified in vitro and in vivo activity of the materials for preventing and treating SLE by alleviating SLE plasma in autoimmune diseases. Therefore, the present invention provides a novel method for screening a therapeutic agent for SLE, and preventing or treating SLE using the mechanism.
