Chronic nephropathies represent a real global public health concern. In particular, nephronophthisis (NPH) is an orphan genetic disease affecting the kidney. This recessive affection usually manifests with polyuria followed by a gradual reduction in kidney function related to progressive renal scarring. To date, no treatment is available for this affection. Now the inventors show that inhibition of the Hippo signalling pathway represents a new therapeutic avenue for the treatment of chronic nephropathies such as NPH. In particular, the inventors show that inhibition of MST1/2 or LATS1/2 reduces the NPH pro-inflammatory signature in mIMCD-3 renal cells even in response to uropathogenic bacteria. Thus the present invention relates to use of inhibitors of the Hippo signalling pathway for the treatment of chronic nephropathies.
