Description
Subjects with incidental Lewy body disease (iLBD) may represent the premotor stage of Parkinsons disease (PD). To identify molecular mechanisms underlying neuronal dysfunction and alpha--synuclein pathology in the premotor phase of PD, we investigated the transcriptome of post-mortem substantia nigra (SN) of iLBD, PD donors and age-matched controls with Braak alpha--synuclein stage ranging from 0-6. In Braak alpha--synuclein stages 1 and 2, we observed deregulation of pathways linked to axonal degeneration, unfolded protein response (UPR), immune response and endocytosis, including axonal guidance signaling, protein kinase A signaling, mTOR signaling, EIF2 signaling and clathrin-mediated endocytosis. In Braak stages 3 and 4, we observed a deregulation in pathways involved in protein translation and cell survival, including mTOR and EIF2 signaling. In Braak stages 5 and 6, we observed deregulation of pathways such as dopaminergic signaling, axonal guidance signaling and thrombin signaling. Throughout the progression of PD pathology, we observed a deregulation of mTOR, EIF2 and regulation of eIF4 and p70S6K signaling in the SN. This implicates that molecular mechanisms related to UPR, axonal dysfunction, endocytosis and immune response are an early event in PD pathology, and may hold the key to altering the disease progression in PD.

Description
The adaptor protein Lnk is an important negative regulator of HSC homeostasis and self-renewal. This study aims to investigate the role of Lnk in HSC aging. Here we performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from young and old WT and Lnk-/- mice. Results identify select Lnk-mediated pathways with potential involvement in HSC self-renewal and aging.
Publication Title
Lnk deficiency partially mitigates hematopoietic stem cell aging.

Description
Previous studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. In addition, we reported that C57Bl/6J mice did not form tumors under the same conditions.

Description
The adaptor protein MERIT40 is a core subunit of deubiquitinating (DUB) complexes that specifically cleave Lysine63-polyubiquitin chains. We found that MERIT40 is an important negative regulator of hematopoietic stem cell (HSC) homeostasis, quiescence and self-renewal. This study aims to investigate the molecular mechanism by which MERIT40 regulates HSC expansion and cell cycle. We performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from WT and Merit40-/- mice. Results identify select MERIT40-mediated pathways with potential involvement in HSC cell cycle regulation.

MERIT40 deficiency expands hematopoietic stem cell pools by regulating thrombopoietin receptor signaling.
