Peculiar neurological symptoms occur in LND: dystonia, choreoathetosis, compulsive self-injurious behaviour, with no obvious correlation to the deficiency of this purine salvage anzyme. A dopaminergic deficit was found to underlie the neurologic symptoms, but the aetiology for such alteration seemed inexplicable. Several lines of research were carried out to find the molecular basis for the neurological phenotype, and HPRT deficient animal and cellular models were developed. None of them, animal or cellular model, can be considered the completely proper one. Available animal models are rodents, which share several biochemical and molecular abnormalities with HPRT deficient patients, but do not display similar neurologic symptoms. Cellular models obtained from different cell lines present notable biochemical and molecular aberrations though many discrepancies suggest significant differences depending upon cell types and tissue source. Nevertheless, experimental studies on both models provided remarkable information on the biochemical and molecular pathways potentially responsible for the neurological damage in this disease, demonstrating transcriptional aberrations affecting different genes in various metabolic pathways and gene dysregulations in neuronal development and differentiation, producing neurotransmission defects. These findings led to attribute an unexpected paramount role in neurodevelopment to HPRT, beside the well-known metabolic functions.</div>","PeriodicalId":39774,"journal":{"name":"Drug Discovery Today: Disease Models","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ddmod.2019.10.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90376298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic studies have identified three genes associated with CCMs: KRIT1 (CCM1), MGC4607 (CCM2) and PDCD10 (CCM3).Recently, great advances in understanding the pathophysiology of CCM disease have been obtained thanks to the use of animal and cellular models displaying all or some of the pathological characteristics that are observed in the human disease.

Overtime, elevated HGA causes connective tissue ochronosis, leading to a severe and early onset osteoarthropathy. The use of HGD deficient mouse models in this metabolic bone disease have provided the opportunity to investigate AKU pathophysiology and potential treatments. An ENU mutagenesis AKU mouse model (BALB/c Hgd−/−) provided the means to explore the onset of pigmentation in cartilage and treatment of AKU with nitisinone, an inhibitor of the upstream enzyme forming HGA. This work provided evidence that nitisinone could not only lower circulating HGA, but could also prevent ochronosis and halt disease progression, leading to its off-label use at the National Alkaptonuria Centre (Liverpool, UK) and its subsequent testing in human clinical trials (DevelopAKUre). Recently, a new targeted AKU mouse model (Hgd tm1a−/−, C57BL/6) has been established, offering a LacZ reporter gene for localising gene expression and LoxP and FRT sites that enabled generation of an inducible and liver-specific HGD knockout model (Hgd tm1d MxCre+/−). This conditional model determined the importance of the liver as a target organ for future gene/enzyme replacement therapies in AKU.

We briefly discussed the differences between both methods in handling expertise, number of mice required, length of time to determine lung function and anesthetic and/or use of muscle relaxant. Since noninvasive method received more criticisms than invasive method, we discussed critically the seminal studies that lend support to the disapproval of that method as measure of lung function. We show that the criticisms to the use of noninvasive method are biased or exaggerated and in general not hampered by experimental data obtained in several studies. Accordingly, in many studies the invasive method confirmed the results obtained with noninvasive method indicating that at practical level both methods were more coincident than discordant. Since both methods for measuring lung function have limitations and merits, we suggest that depending on focus of the study one method could be more adequate than the other. In studies where lung mechanical function is the main focus, the invasive method might be required. However, when determination of lung function is just one parameter among several others that characterizes lung disease, the noninvasive method might fit better since it allows performing longitudinal determinations of lung function followed by other lung pathologic parameters using smaller numbers of animals. Finally, in some studies the noninvasive method could be used to screen different experimental protocols and then the invasive method applied to confirm the positive results.</div>","PeriodicalId":39774,"journal":{"name":"Drug Discovery Today: Disease Models","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ddmod.2019.07.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73780081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
