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 first to describe the functional neuropathology of SCA14 in post-mortem cerebellum as well as in human iPSCs derived from patients with SCA14 mutations. Unexpectedly, PKC CD276/B7-H3 Protein HEK 293 aggregation, mislocalization and elevated kinase activity that we observed in SCA14 cerebellum were reproduced in SCA14 iPSCs. Purkinje cells are specifically vulnerable in SCA14, most likely on account of their higher expression of PKC and its distinct targets that regulate the calcium homeostasis plus the distinctive physiological properties of these neurons. When the latter can not be modelled in undifferentiated stem cells, the truth that patient iPSCs express PKC and recapitulate important 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 is going to be differentiated to Purkinje cells.
