Final answer:
Constructing a disease helps connect diseases with similar gene expression patterns and aims to identify new drug targets, which is essential for the development of personalized medicine and specific treatments like antisense therapy.
Step-by-step explanation:
Constructing a "diseasome" is a way to connect diseases that share certain gene expression patterns. A goal of this approach is to identify new drug targets.
Understanding gene expression patterns in cancer cells is key to identifying the faulty genes, which aids in developing targeted drug treatments. This approach is integral to the field of personalized medicine, whereby therapy and medicines are tailored to an individual's specific genetic makeup.
Antisense therapy is a relevant technique related to gene expression alterations. It addresses diseases where genes are deregulated by designing nucleic acid sequences to block the synthesis of gene products, leading to reduced target protein production. This is used in treating a variety of conditions, including various cancers and genetic diseases.
