WebDec 14, 2016 · A new X-linked tumor suppressor gene that escapes X inactivation drives higher expression of its encoded protein PR70—the regulatory subunit of protein phosphatase 2A—in females and might explain the worse prognoses observed in men with melanoma, relative to women. WebPrevious studies suggest that a down-regulation of protein phosphatase 2A (PP2A), the major tau phosphatase in human brain, contributes to tau hyperphosphorylation in AD. However, the effects of PP2A down-regulation on site-specific tau hyperphosphorylation is not well understood.
