Ossifying fibromyxoid tumor: morphology, genetics, and differential diagnosis.
London, United Kingdom. In Ann Diagn Pathol, Jan 2016
It is now established that OFMTs represent translocation-associated tumors, with up to 85% associated with recurrent gene rearrangements, mostly involving the PHF1 gene (including in typical, atypical, and malignant neoplasms), with EP400-PHF1 in approximately 40% of tumors, and ZC3H7B-BCOR, MEAF6-PHF1, and EPC1-PHF1 fusions also described.
Effect of treadmill exercise on PI3K/AKT/mTOR, autophagy, and Tau hyperphosphorylation in the cerebral cortex of NSE/htau23 transgenic mice.
Seoul, South Korea. In J Exerc Nutrition Biochem, Sep 2015
Western blot was conducted to determine the phosphorylation status of PI3K/AKT/mTOR proteins and autophagy-related proteins (Beclin-1, p62, LC3-B); hyperphosphorylation and aggregation of tau protein (Ser199/202, Ser404, Thr231, PHF-1); and phosphorylation of GSK-3β, which is involved in the phosphorylation of tau protein in the cerebral cortex of experimental animals.
Tudor: a versatile family of histone methylation 'readers'.
Chapel Hill, United States. In Trends Biochem Sci, 2013
Here, we discuss novel functions of a number of Tudor-containing proteins [including Jumonji domain-containing 2A (JMJD2A), p53-binding protein 1 (53BP1), SAGA-associated factor 29 (SGF29), Spindlin1, ubiquitin-like with PHD and RING finger domains 1 (UHRF1), PHD finger protein 1 (PHF1), PHD finger protein 19 (PHF19), and SAWADEE homeodomain homolog 1 (SHH1)] in 'reading' unique methylation events on histones in order to facilitate DNA damage repair or regulate transcription.
Cultured cell and transgenic mouse models for tau pathology linked to beta-amyloid.
Charlottesville, United States. In Biochim Biophys Acta, 2005
We report here that continuous exposure to 5 microM non-fibrillar Abeta40 or Abeta42 kills primary brain cells by apoptosis within 2-3 weeks, Abeta42 is more toxic and selective for neurons than Abeta40, and Abeta42, but not Abeta40, induces a transient increase in neurons that are positive for the AD-like PHF1 epitope.
