Pesquisa de alvos terapêuticos no quadro da nefronoftise e das ciliopatias renais associadas (NPH1)

Pesquisa de alvos terapêuticos no quadro da nefronoftise e das ciliopatias renais associadas - NPH_1

Nephronophthisis (NPH) is an autosomal recessive, genetically heterogeneous disease, with mutations identified in over 20 genes (notably NPHP1 and NPHP4).

These genetic defects are associated with reduced urine concentration, chronic tubulointerstitial nephritis, etc., and progress to end-stage renal failure before the age of 20.

Nephronophthisis may occur as an isolated pathology, but is also often associated with various extrarenal symptoms.

NPHP genes account for around 50% of the genes responsible for NPH. No effective treatment is available to date.

Studying NPHP proteins and associated signaling pathways could help identify how to circumvent the problems of protein distribution and therapeutic mRNA, and could be applicable to a broad set of NPHP mutations. To this end, Dr. Saunier's laboratory at Institut Imagine has recently identified approved drugs that correct some of the ciliary and epithelial defects found in cells with NPHP mutations.

Descrição detalhada

Nephronophthisis (NPH) is an autosomal recessive, genetically heterogeneous disease, with mutations identified in over 20 genes (notably NPHP1 and NPHP4).

These genetic defects are associated with reduced urine concentration, chronic tubulointerstitial nephritis, etc., and progress to end-stage renal failure before the age of 20.

Nephronophthisis may occur as an isolated pathology, but is also often associated with various extrarenal symptoms such as retinal dystrophy, cerebellar vermis hypoplasia, skeletal dysmorphisms and/or situs/inversus. These disorders overlap phenotypically, genetically and functionally. All are thought to result from defective ciliary signaling and are classified as renal ciliopathies.

NPHP genes account for around 50% of the genes responsible for NPH. No effective treatment is available to date.

One possible therapeutic approach is to replace the defective protein; but delivery of recombinant proteins or mRNA to renal tubular cells is not currently feasible. However, each NPHP protein participates in numerous intracellular signalling pathways involving cilia functions.

Studying NPHP proteins and associated signaling pathways could help identify how to circumvent the problems of protein distribution and therapeutic mRNA, and could be applicable to a broad set of NPHP mutations. To this end, Dr. Saunier's laboratory at Institut Imagine has recently identified approved drugs that correct some of the ciliary and epithelial defects found in cells with NPHP mutations.

The global research project of which this protocol is a part seeks to identify new specific targets and develop new therapeutic agents against these targets for the treatment of NPH and other ciliopathies.

Descrição

Inclusion Criteria:

  • In order to be included in the protocol, subjects will have to respect the following criteria:

Affected patients:

Suffering from nephronophthisis or renal associated ciliopathies with known genetic diagnosis or not, Having obtained the signature of the informed consent form of patient, parent(s) or legal representative No age limit is requested for these patients, who can be recruited from birth.

Healthy relatives:

Being the healthy relative (father / mother / brother / sister) of an included patient Having signed the informed consent form (patient or parent in case of minor subject) No age limit is requested for these subjects, who can be recruited from birth.

'Negative' control patients: Being unscathed of any chronic renal disease, with or without ciliopathies Having obtained the signature of the informed consent form No age limit is requested for these patients, who can be recruited from birth.

'Positive' control patients Suffering from Chronic Kidney Disease unrelated to ciliary dysfunction (such as glomerulopathy, tubulopathy…) Having obtained the signature of the informed consent form No age limit is requested for these patients, who can be recruited from birth.

Exclusion Criteria:

In order to be included in the protocol, subjects will have to fulfill none of the following criteria:

Affected patients:

Outro: Patients with nephronophthisis/renal associated ciliopathies

Affected patients:

Suffering from nephronophthisis or renal associated ciliopathies with known genetic diagnosis or not, Having obtained the signature of the informed consent form of patient, parent

Intervention : blood and urine sample collection Collection of urines from patients will be followed by multiomics analyses including proteome and miRNAome profiling on EVs purified from urines by ultracentrifugation and metabolomics on unfractionated urine. Biomarkers identification for ciliopathy-induced chronic kidney disease will allow to monitor the drug response in treated urine-derived renal epithelial cells.
