The method as disclosed herein utilizes a high throughput screening assay (GigaAssay) to produce a comprehensive mutation effect on gene activity (MEGA)-mutation activity profile (Map). The methods as disclosed herein can be used to assess the mutational effect for any gene, under any condition (e.g., drug treatment) with any assay in mammalian cells in culture. Thus, the methods provided herein can be utilized to discover and screen dominant negative variants, and provide a reliable solution to the problem of identifying unique pharmacologically active variants of proteins. Furthermore, the method provided herein can be integrated to cell-based assays to investigate disease pathology and test potential drugs.

The present invention provides a double-stranded RNA used to suppress the expression of mannan-binding lectin-related serine protease 2 (MASP2) in cells, cells containing the nucleotide encoding the same, and a method for treating a disease or condition mediated by or related to MASP2 expression in a subject using the dsRNA or cells.

The invention discloses a test method of reaction of EPHX1 genotype based COPD to NAC. The test method comprises the following steps: extracting a DNA by a phenol / chloroform method and sequencing, dividing COPD patients into slow and very slow gene activity group and a quick and normal gene activity group according to EPHX1 gene polymorphism, giving 600 mg Bid of NAC for 1 year to both groups, performing baseline measurement of pulmonary function parameters, completing SGRQ and 6MWT, measuring FVC and FEV1 at a follow-up day every 12 weeks, completingSGRQ and 6MWT in 24 and 48 weeks, and recording the number of acute exacerbationof COPD in one year. The data were statistically analyzed with SPSS. The results show that NAC is effective in the treatment of slow and very slow EPHX1 gene activityCOPD patients. The test method provided by the invention provides a solid basis for demonstrating the effect and mechanism of NAC based on pharmacogenomics in the individualized treatment of COPD.

This invention discloses a KDM4C inhibitor and its applications, relating to the field of biomedical technology. Specifically, this invention discloses the application of the KDM4C inhibitor in any of A1) to A5): A1) preparing a drug for the prevention or treatment of obesity; A2) preparing a drug for reducing weight; A3) preparing a drug for reducing food intake; A4) preparing a drug for reducing insulin sensitivity; A5) preparing a drug for enhancing glucose homeostasis. This is achieved through knockout... Kdm4c Inhibiting KDM4C gene activity or inhibiting KDM4C activity can significantly reduce obesity induced by a high-fat diet, thereby regulating the secretion of related hormones / adipokines, affecting food intake, improving insulin resistance, and enhancing insulin sensitivity, making it a potential target for the treatment of obesity.
