Properties of Non-Aminoglycoside Compounds Used to Stimulate Translational Readthrough of PTC Mutations in Primary Ciliary Dyskinesia

چکیده
Primary ciliary dyskinesia (PCD) is a rare disease with autosomal recessive inheritance, caused mostly by bi-allelic gene mutations that impair motile cilia structure and function. Currently, there are no causal treatments for PCD. In many models, translational readthrough of premature termination codons (PTC-readthrough) induced aminoglycosides has been proposed as an effective way restoring functional protein expression reducing symptoms. However, variable outcomes pre-clinical trials toxicity associated long-term use prompt the search other compounds might overcome these problems. Because high proportion PCD-causing variants nonsense mutations, therapies attractive option. We tested group chemical known PTC-readthrough potential (ataluren, azithromycin, tylosin, amlexanox, experimental compound TC007), collectively referred to non-aminoglycosides (NAGs). investigated their efficiency in six PTC found Polish PCD patients, context cell health, comparison previously aminoglycosides. The NAGs did not compromise viability primary nasal respiratory epithelial cells, beat frequency was retained, similar what observed gentamicin. HEK293 cells transfected PTC-containing inserts, stimulated but lower than study allowed us select minimal negative impact on function still induce PTC-readthrough.

Aminoglycoside-stimulated readthrough of premature termination codons in selected genes involved in primary ciliary dyskinesia
Translational readthrough of premature termination codons (PTCs) induced by pharmacological compounds has proven to be an effective way of restoring functional protein expression and reducing symptoms in several genetic disorders. We tested the potential of different concentrations of several aminoglycosides (AAGs) for promoting PTC-readthrough in 5 genes involved in the pathogenesis of primary...
متن کاملPrimary ciliary dyskinesia.
Primary ciliary dyskinesia (PCD) is a rare genetic condition that affects the ciliary function of the respiratory tract, sperm tail, cilia of the embryonic node, and fallopian tube. The condition is characterized by impaired ciliary action, leading to recurrent lower-respiratory-tract infections, bronchiectasis, rhino-sinusitis, otitis media, impaired fertility in women, and infertility in men....

Primary ciliary dyskinesia (PCD) is a genetic disorder of cilia structure and function, chronic infections of the respiratory tract, fertility problems and disorders of organ laterality. Establishing a definitive diagnosis can be challenging, requiring a compatible phenotype and detection of ciliary functional and ultra-structural defects, along with newer screening tools such as nasal nitric o...
متن کاملPrimary Ciliary Dyskinesia
Primary ciliary dyskinesia (PCD) is caused by ultrastructural ciliary defects that lead to abnormal ciliary beating and, subsequently, mucociliary dysfunction. PCD presents clinically with bronchiectasis, sinusitis, and, in up to 50% of cases, situs inversus. The ultrastructural defects of cilia are diverse but include in many cases outer and/or inner dynein arms. Recent advances have shown tha...
