      The CRISPR/Cas9 system has been implemented in a variety of model organisms to mediate site-directed mutagenesis. A wide range of mutation rates has been reported, but at a limited number of genomic target sites. To uncover ...
    • Genomic Imprinting in the Brain: the persistent influences from Mom and Dad 

      Perez, Julio David (2015-05-20)
      Most mammalian genes are equally expressed from the two inherited parental alleles. However, a puzzling subgroup known as imprinted genes are preferentially expressed from either the maternally- or paternally-inherited ...
    • Identification of an Operant Learning Circuit by Whole Brain Functional Imaging in Larval Zebrafish 

      Li, Jennifer Mengbo (2013-08-21)
      When confronted with changing environments, animals can generally adjust their behavior to optimize reward and minimize punishment. The process of modifying one's behavior based on its consequences is referred to as operant ...
    • Internal guide RNA interactions interfere with Cas9-mediated cleavage 

      Thyme, Summer B.; Akhmetova, Laila; Montague, Tessa G.; Valen, Eivind; Schier, Alexander F. (Nature Publishing Group, 2016)
      The CRISPR/Cas system uses guide RNAs (gRNAs) to direct sequence-specific DNA cleavage. Not every gRNA elicits cleavage and the mechanisms that govern gRNA activity have not been resolved. Low activity could result from ...
    • Members of the miRNA-200 Family Regulate Olfactory Neurogenesis 

      Choi, Wen-Yee; Caron, Sophie; Alvarez-Saavedra, Ezequiel; Miska, Eric A.; McManus, Mike; Harfe, Brian; Giraldez, Antonio J.; Horvitz, Robert H.; Choi, Philip S.; Zakhary, Lisa Maher; Schier, Alexander F; Dulac, Catherine (Elsevier, 2008)
      Summary: MicroRNAs (miRNAs) are highly expressed in vertebrate neural tissues, but the contribution of specific miRNAs to the development and function of different neuronal populations is still largely unknown. We report ...
    • Monitoring Neural Activity with Bioluminescence during Natural Behavior 

      Naumann, Eva Aimable; Kampff, Adam R.; Prober, David A.; Schier, Alexander F; Engert, Florian (Nature Publishing Group, 2010)
      Existing techniques for monitoring neural activity in awake, freely behaving vertebrates are invasive and difficult to target to genetically identified neurons. We used bioluminescence to non-invasively monitor the activity ...
    • Multicolor Brainbow Imaging in Zebrafish 

      Pan, Y. A.; Livet, J.; Sanes, Joshua R.; Lichtman, Jeff; Schier, Alexander F (Cold Spring Harbor Laboratory Press, 2011)
      This protocol describes how to use the Brainbow strategy to label neurons in many different hues. The Brainbow system uses a random Cre/lox recombination to create varied combinations of red, blue, and green fluorescent ...
    • Nanog-like Regulates Endoderm Formation through the Mxtx2-Nodal Pathway 

      Xu, Cong; Fan, Zi Peng; Müller, Patrick; Fogley, Rachel; DiBiase, Anthony; Trompouki, Eirini; Unternaehrer, Juli; Xiong, Fengzhu; Torregroza, Ingrid; Evans, Todd; Megason, Sean; Daley, George Quentin; Schier, Alexander F; Young, Richard A.; Zon, Leonard Ira (Elsevier, 2012)
      In mammalian embryonic stem cells, the acquisition of pluripotency is dependent on Nanog, but the in vivo analysis of Nanog has been hampered by its requirement for early mouse development. In an effort to examine the role ...
