Recombinant insulin-like growth factor binding protein-4 inhibits proliferation and promotes differentiation of neural progenitor cells Neuroscience Letters 2017 MAR
Abstract
Insulin-like growth factor (IGF) is involved in regulating many processes during neural development, and IGF binding protein-4 (IGFBP4) functions as a modulator of IGF actions or in an IGF-independent manner (e.g., via inhibiting Wnt/β-catenin signaling). In the present study, neural progenitor cells (NPCs) were isolated from the forebrain of newborn mice to investigate effects of IGFBP4 on the proliferation and differentiation of NPCs. The proliferation of NPCs was evaluated using Cell Counting Kit-8 (CCK-8) after treatment with or without IGFBP4 as well as blockers of IGF-IR and β-catenin. Phosphorylation levels of Akt, Erk1, 2 and p38 were analyzed by Western blotting. The differentiation of NPCs was evaluated using immunofluorescence and Western blotting. It was shown that exogenous IGFBP4 significantly inhibited the proliferation of NPCs and it did not induce a more pronounced inhibition of cell proliferation after blockade of IGF-IR but it did after antagonism of β-catenin. Akt phosphorylation was significantly decreased and phosphorylation levels of Erk1, 2 and p38 were not significantly changed in IGFBP4-treated NPCs. Excessive IGFBP4 significantly promoted NPCs to differentiate into astrocytes and neurons. These data suggested that exogenous IGFBP4 inhibits proliferation and promotes differentiation of neural progenitor cells mainly through IGF-IR signaling pathway.
Cathepsin B Improves ß-Amyloidosis and Learning and Memory in Models of Alzheimer's Disease. Journal of neuroimmune pharmacology : the official journal of the Society on NeuroImmune Pharmacology 2017 JUN
Abstract
Amyloid-ß (Aß) precursor protein (APP) metabolism engages neuronal endolysosomal pathways for Aß processing and secretion. In Alzheimer's disease (AD), dysregulation of APP leads to excess Aß and neuronal dysfunction; suggesting that neuronal APP/Aß trafficking can be targeted for therapeutic gain. Cathepsin B (CatB) is a lysosomal cysteine protease that can lower Aß levels. However, whether CatB-modulation of Aß improves learning and memory function deficits in AD is not known. To this end, progenitor neurons were infected with recombinant adenovirus expressing CatB and recovered cell lysates subjected to proteomic analyses. The results demonstrated Lamp1 deregulation and linkages between CatB and the neuronal phagosome network. Hippocampal injections of adeno-associated virus expressing CatB reduced Aß levels, increased Lamp1 and improved learning and memory. The findings were associated with the emergence of c-fos + cells. The results support the idea that CatB can speed Aß metabolism through lysosomal pathways and as such reduce AD-associated memory deficits.
Qki deficiency maintains stemness of glioma stem cells in suboptimal environment by downregulating endolysosomal degradation. Nature genetics 2017 JAN
Abstract
Stem cells, including cancer stem cells (CSCs), require niches to maintain stemness, yet it is unclear how CSCs maintain stemness in the suboptimal environment outside their niches during invasion. Postnatal co-deletion of Pten and Trp53 in mouse neural stem cells (NSCs) leads to the expansion of these cells in their subventricular zone (SVZ) niches but fails to maintain stemness outside the SVZ. We discovered that Qki is a major regulator of NSC stemness. Qk deletion on a Pten-/-; Trp53-/- background helps NSCs maintain their stemness outside the SVZ in Nes-CreERT2; QkL/L; PtenL/L; Trp53L/L mice, which develop glioblastoma with a penetrance of 92% and a median survival time of 105 d. Mechanistically, Qk deletion decreases endolysosome-mediated degradation and enriches receptors essential for maintaining self-renewal on the cytoplasmic membrane to cope with low ligand levels outside niches. Thus, downregulation of endolysosome levels by Qki loss helps glioma stem cells (GSCs) maintain their stemness in suboptimal environments outside their niches.
