Eased PKC substrate phosphorylation. Human stem cells express each canonical and non-canonical PKC isoforms [24] and Purkinje cells have been shown to express PKC, PKC, PKC and PKC [45].Conclusions Our study may be the initially to describe the functional neuropathology of SCA14 in post-mortem cerebellum at the same time as in human iPSCs derived from individuals with SCA14 mutations. Unexpectedly, PKC aggregation, mislocalization and elevated kinase activity that we observed in SCA14 cerebellum were reproduced in SCA14 iPSCs. Purkinje cells are especially vulnerable in SCA14, most likely resulting from their higher expression of PKC and its specific targets that regulate the calcium homeostasis and also the distinctive physiological IL-2R gamma Protein medchemexpress properties of these neurons. Although the latter can not be modelled in undifferentiated stem cells, the truth that patient iPSCs express PKC and recapitulate key pathological findings observed in SCA14 cerebellum underscores their prospective as relevant tools for illness modeling and drug discovery, as well as future studies in which SCA14 iPSCs will probably be differentiated to Purkinje cells.
