    Description: In the adult central nervous system, the vasculature of the neurogenic niche regulates neural stem cell behavior by providing circulating and secreted factors. Age-related decline of neurogenesis and cognitive function is associated with reduced blood flow and decreased numbers of neural stem cells. Therefore, restoring the functionality of the niche should counteract some of the negative effects of aging. We show that factors found in young blood induce vascular remodeling, culminating in increased neurogenesis and improved olfactory discrimination in aging mice. Further, we show that GDF11 alone can improve the cerebral vasculature and enhance neurogenesis. The identification of factors that slow the age-dependent deterioration of the neurogenic niche in mice may constitute the basis for new methods of treating age-related neurodegenerative and neurovascular diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4123747/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4123747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katsimpardi, Lida -- Litterman, Nadia K -- Schein, Pamela A -- Miller, Christine M -- Loffredo, Francesco S -- Wojtkiewicz, Gregory R -- Chen, John W -- Lee, Richard T -- Wagers, Amy J -- Rubin, Lee L -- 1DP2 OD004345/OD/NIH HHS/ -- 1R01 AG033053/AG/NIA NIH HHS/ -- 1R01 AG040019/AG/NIA NIH HHS/ -- 5U01 HL100402/HL/NHLBI NIH HHS/ -- DP2 OD004345/OD/NIH HHS/ -- R01 AG032977/AG/NIA NIH HHS/ -- R01 AG033053/AG/NIA NIH HHS/ -- R01 AG040019/AG/NIA NIH HHS/ -- R01 NS070835/NS/NINDS NIH HHS/ -- R01 NS072167/NS/NINDS NIH HHS/ -- R01NS070835/NS/NINDS NIH HHS/ -- R01NS072167/NS/NINDS NIH HHS/ -- U01 HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):630-4. doi: 10.1126/science.1251141.

    Description: Frame-disrupting mutations in the DMD gene, encoding dystrophin, compromise myofiber integrity and drive muscle deterioration in Duchenne muscular dystrophy (DMD). Removing one or more exons from the mutated transcript can produce an in-frame mRNA and a truncated, but still functional, protein. In this study, we developed and tested a direct gene-editing approach to induce exon deletion and recover dystrophin expression in the mdx mouse model of DMD. Delivery by adeno-associated virus (AAV) of clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 endonucleases coupled with paired guide RNAs flanking the mutated Dmd exon23 resulted in excision of intervening DNA and restored the Dmd reading frame in myofibers, cardiomyocytes, and muscle stem cells after local or systemic delivery. AAV-Dmd CRISPR treatment partially recovered muscle functional deficiencies and generated a pool of endogenously corrected myogenic precursors in mdx mouse muscle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tabebordbar, Mohammadsharif -- Zhu, Kexian -- Cheng, Jason K W -- Chew, Wei Leong -- Widrick, Jeffrey J -- Yan, Winston X -- Maesner, Claire -- Wu, Elizabeth Y -- Xiao, Ru -- Ran, F Ann -- Cong, Le -- Zhang, Feng -- Vandenberghe, Luk H -- Church, George M -- Wagers, Amy J -- 1DP2OD004345/OD/NIH HHS/ -- 5DP1-MH100706/DP/NCCDPHP CDC HHS/ -- 5PN2EY018244/EY/NEI NIH HHS/ -- 5R01DK097768-03/DK/NIDDK NIH HHS/ -- 5U01HL100402/HL/NHLBI NIH HHS/ -- P50 HG005550/HG/NHGRI NIH HHS/ -- T2GM007753/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):407-11. doi: 10.1126/science.aad5177.

    Description: Parabiosis experiments indicate that impaired regeneration in aged mice is reversible by exposure to a young circulation, suggesting that young blood contains humoral "rejuvenating" factors that can restore regenerative function. Here, we demonstrate that the circulating protein growth differentiation factor 11 (GDF11) is a rejuvenating factor for skeletal muscle. Supplementation of systemic GDF11 levels, which normally decline with age, by heterochronic parabiosis or systemic delivery of recombinant protein, reversed functional impairments and restored genomic integrity in aged muscle stem cells (satellite cells). Increased GDF11 levels in aged mice also improved muscle structural and functional features and increased strength and endurance exercise capacity. These data indicate that GDF11 systemically regulates muscle aging and may be therapeutically useful for reversing age-related skeletal muscle and stem cell dysfunction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4104429/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4104429/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinha, Manisha -- Jang, Young C -- Oh, Juhyun -- Khong, Danika -- Wu, Elizabeth Y -- Manohar, Rohan -- Miller, Christine -- Regalado, Samuel G -- Loffredo, Francesco S -- Pancoast, James R -- Hirshman, Michael F -- Lebowitz, Jessica -- Shadrach, Jennifer L -- Cerletti, Massimiliano -- Kim, Mi-Jeong -- Serwold, Thomas -- Goodyear, Laurie J -- Rosner, Bernard -- Lee, Richard T -- Wagers, Amy J -- 1DP2 OD004345/OD/NIH HHS/ -- 1R01 AG033053/AG/NIA NIH HHS/ -- 1R01 AG040019/AG/NIA NIH HHS/ -- 5U01 HL100402/HL/NHLBI NIH HHS/ -- DP2 OD004345/OD/NIH HHS/ -- P30 AG038072/AG/NIA NIH HHS/ -- R01 AG032977/AG/NIA NIH HHS/ -- R01 AG033053/AG/NIA NIH HHS/ -- R01 AG040019/AG/NIA NIH HHS/ -- R01 AR042238/AR/NIAMS NIH HHS/ -- R01 AR42238/AR/NIAMS NIH HHS/ -- T32 DE007057/DE/NIDCR NIH HHS/ -- U01 HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):649-52. doi: 10.1126/science.1251152.
