Antisense therapy is a type of treatment that can be used to treat disorders or disease. Drugs are used to treat cancers, diabetes, asthma, arthritis, HIV/AIDS, high cholesterol, or hemorrhagic fever viruses. Many diseases are linked to the production of certain protein; if this production is somehow stopped to disturbed, the disease can be cured. Antisense therapy works in such a way that, a special synthesized stand of short RNA binds to mRNA product of the disease. When this happens, the gene shuts down, and it is deactivated; this causes the disease from reproducing and eventually dies. Antisense drugs are designed in such a way that they bind to the mRNA of a target protein, inhibiting the production process of that specific protein.
