DYRKs regulate cell proliferation, apoptosis, survival, and differentiation by modifying the protein activation state, cellular localization, and turnover. In contrast to several studies in cellular models, the available evidence regarding the in vivo roles of DYRKs in mammalian development is limited. This review summarizes the in vivo studies on Dyrks which provide insight into their roles in mammalian tissue development and congenital diseases. In vivo evidence obtained using knockout and genetically modified animals helps to understand and develop novel clinical therapies and drug for human congenital diseases, such as Down syndrome and neuronal disorders (associated with DYRK1A) and skeletal ciliopathies (associated with DYRK2).展开更多

Mutations in NLRP12 cause exceptionally rare NLRP12-associated autoinflammatory disease (NLRP12-AID). So far, very few patients with NLRP12-AID have been identified worldwide;therefore, data on the clinical phenotype and genetic profile are limited. In this study, we reported 10 patients who presented mainly with periodic fever syndrome or arthritis. Next-generation sequencing (NGS) identified 6 heterozygous mutations of NLRP12, including 2 novel null mutations. Of the patients, some with same mutations showed different clinical features. Compared to healthy controls, the increased levels of cytokines were revealed in the patients' plasmas, as well as in the supernatants of patients’ cells stimulated with lipopolysaccharide (LPS) or tumor necrosis factor-α (TNF-α). The missense mutations did not change the protein expression;but decreased level of NLRP12 protein was shown in the null mutations. And in vitro expression assay demonstrated a truncating protein induced by the frameshift mutation. Further functional studies revealed the deleterious effect of mutations on nuclear factor-kappa B (NF-κB) signaling. Both the null and missense mutations impaired their inhibition of NF-κB activation induced by p65. Collectively, this study reported a relatively large NLRP12-AID case series. Our findings expand the clinical spectrum, and reinforce the diversity of genetic mutations and clinical phenotypes. The NLRP12-associated disorder should be considered when autoinflammatory diseases are encountered in the clinical practice, especially for patients presenting with periodic fever but no other genetic cause identified.展开更多
