The invention discloses application of a
CC chemokine receptor 7 inhibitor in preparation of a
medicine for treating
cardiac hypertrophy. The CC type
chemokine receptor 7 (
chemokine (C-C motif) ligand 7, CCL7) inhibitor comprises a
reagent which can be used for inhibiting the expression of a CCL7
gene at the transcription or translation level of the CCL7
gene. Preferably, the
CC chemokine receptor 7 inhibitor comprises siRNA (small interfering Ribonucleic Acid), shRNA (short hairpin Ribonucleic Acid), a carrier or a
virus containing the siRNA / shRNA, and an
antibody of CCL7. According to the application disclosed by the invention, a new function of the CCL7 is found, that is, the CCL7 has an effect of worsening
myocardial hypertrophy; the invention further provides application of the
CC chemokine receptor 7 as a
drug target in screening of drugs for preventing, relieving and / or treating
cardiac hypertrophy and application of a CCL7 inhibitor in preparation of drugs for preventing, relieving and / or treating
cardiac hypertrophy. The invention provides a new technical means for preventing, relieving and / or treating cardiac hypertrophy.
