Unexpectedly, we found that 4R NM human tau (hTau) exhibited abnormal dynamics in young mice that were lost with the P301L mutation, including elevated protein stability and hyperphosphorylation, which were associated with cognitive impairment in 5-month old rT1 mice.
Overall, our genetically matched mice have revealed that 4R NM hTau over expression is pathogenic in a manner distinct from classical aging-related tauopathy, underlining the importance of assaying the effects of transgenic disease-related proteins at appropriate stages in life.<b>SIGNIFICANCE STATEMENT</b>Due to differences in creation of transgenic lines, the pathological properties the P301L mutation confers to the tau protein <i>in vivo</i> have remained elusive, perhaps contributing to the lack of disease-modifying therapies for tauopathies.
From analysis of naturally occurring pVHL mutants, it seems that only point mutations such as pVHL(Y98H) and pVHL(Y112H) (that predispose to haemangioblastoma and phaeochromocytoma, but not to renal cell carcinoma) disrupt pVHL's microtubule-stabilizing function.
