      Poor prognosis in neuroblastoma is associated with genetic amplification of MYCN. MYCN is itself a target of let-7, a tumor suppressor family of microRNAs implicated in numerous cancers. LIN28B, an inhibitor of let-7 ...

(National Academy of Sciences, 2012)
      Transactive response DNA-binding (TDP-43) protein is the dominant disease protein in amyotrophic lateral sclerosis (ALS) and a sub-group of frontotemporal lobar degeneration (FTLD-TDP). Identification of TARDBP mutations ...

    • 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 ...

    • Optimization of scarless human stem cell genome editing 

      Yang, Luhan; Guell, Marc; Byrne, Susan; Yang, Joyce L.; De Los Angeles, Alejandro; Mali, Prashant; Aach, John; Kim-Kiselak, Caroline; Briggs, Adrian W; Rios, Xavier; Huang, Po-Yi; Daley, George; Church, George (Oxford University Press, 2013)
      Efficient strategies for precise genome editing in human-induced pluripotent cells (hiPSCs) will enable sophisticated genome engineering for research and clinical purposes. The development of programmable sequence-specific ...

    • Precise let-7 expression levels balance organ regeneration against tumor suppression 

      Wu, Linwei; Nguyen, Liem H; Zhou, Kejin; de Soysa, T Yvanka; Li, Lin; Miller, Jason B; Tian, Jianmin; Locker, Joseph; Zhang, Shuyuan; Shinoda, Gen; Seligson, Marc T; Zeitels, Lauren R; Acharya, Asha; Wang, Sam C; Mendell, Joshua T; He, Xiaoshun; Nishino, Jinsuke; Morrison, Sean J; Siegwart, Daniel J; Daley, George Q; Shyh-Chang, Ng; Zhu, Hao (eLife Sciences Publications, Ltd, 2015)
      The in vivo roles for even the most intensely studied microRNAs remain poorly defined. Here, analysis of mouse models revealed that let-7, a large and ancient microRNA family, performs tumor suppressive roles at the expense ...

    • Regulation of Stem Cell Metabolism by the Lin28/let-7 Axis 

      Ng, Shyh Chang (2014-02-25)
      My PhD thesis is focused on two fundamental aspects of stem cell metabolism: (1) the role of Lin28 in programming stem cell metabolism, and (2) how metabolism in turn fuels and governs pluripotency. Our studies led us to ...

    • Reprogramming of T Cells From Human Peripheral Blood 

      Loh, Yuin-Han; Hartung, Odelya; Li, Hu; Guo, Chunguang; Sahalie, Julie M.; Manos, Philip D.; Urbach, Achia; Heffner, Garrett C.; Grskovic, Marica; Vigneault, Francois; Lensch, Willy; Park, In-Hyun; Agarwal, Suneet; Church, George; Collins, James; Irion, Stefan; Daley, George (Elsevier BV, 2010-07-02)

    • Reprogramming Pediatric Genetic Disorders: Pearson Syndrome, Ring 14 Syndrome, and Fanconi Anemia 

      Cherry, Anne Blanche Cresswell (2014-06-06)
      The effect of a single genetic mutation can vary greatly between different types of cells. The mutated gene may not be expressed in one tissue but may cause a devastating loss of function in another. To learn about disease ...
