The invention belongs to the field of research of biomedicines, and particularly relates to application of a human DNAJC24
gene as a target to preparation of medicines for treating
lung cancers or medicines for diagnosing the
lung cancers. Based on extensive and profound researching finding, by adopting a RNAi method, expression of the human DNAJC24 is regulated-down, so that proliferation of thelung
cancer cells can be effectively inhibited and
cell apoptosis is promoted, and a growth progress of the
lung cancers can be effectively controlled. According to the siRNA or a
nucleic acid construction body including an siRNA sequence and chronic viruses provided by the invention, the proliferation velocity of the
lung cancer cells can be specifically inhibited, the
cell apoptosis of the lungcancers is promoted,
cell cloning of the lung cancers is inhibited,
cell invasion of the lung cancers is inhibited, cell transferring of the lung cancers is inhibited, and growth of the lung cancers is inhibited, so that the lung cancers can be treated, and a new direction is developed for treatment of the lung cancers.
