gene therapy

Gene therapy typically involves gene silencing, gene enhancement, and gene modification: gene silencing refers to the phenomenon in which specific genes in an organism are not expressed or reduced in expression for some reason. Gene silencing can occur naturally or be achieved through human manipulation. Here, gene silencing specifically refers to a medical technique of gene therapy. Because gene silencing only affects pathogenic genes and does not affect other unrelated genes, it has good targeting and minimal adverse reactions, demonstrating great potential and application prospects in clinical treatment. Gene enhancement is a gene therapy method that compensates for defective gene function. It transfers normally functioning genes to cells with gene defects or deletions to express normal products, thereby achieving the goal of disease treatment. Gene enhancement, as an emerging technology, brings benefits to humanity but also carries certain risks. To ensure safety, the implementation of gene enhancement must carefully evaluate the insertion position of exogenous genes.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Genes are the basic functional units that carry biological genetic information and are a specific sequence located on chromosomes. Gene therapy is the process of introducing exogenous normal genes into target cells to correct or compensate for diseases caused by genetic defects and abnormalities, achieving the therapeutic goal. The basic process of gene therapy includes: acquisition of therapeutic genes, selection of gene vectors, selection of target cells, determination of gene transfer methods, selection and identification of transduced cells, and reinfusion into the body. Among them, each step is an extremely complex and important process. Gene therapy is mainly used in some genetic diseases, malignant tumors, cardiovascular diseases, infectious diseases, etc.
