Difficulties translating antisense-mediated activation of Frataxin expression from cell culture to mice

Audrius Kilikevicius, Jun Wang, Xiulong Shen, Frank Rigo, Thahza P. Prakash, Marek Napierala & David R. Corey
Friedreich’s ataxia (FA) is an inherited neurodegenerative disorder caused by decreased expression of frataxin (FXN) protein. Previous studies have shown that antisense oligonucleotides (ASOs) and single-stranded silencing RNAs can be used to increase expression of frataxin in cultured patient-derived cells. In this study, we investigate the potential for oligonucleotides to increase frataxin expression in a mouse model for FA. After confirming successful in vivo delivery of oligonucleotides using a benchmark gapmer targeting the nuclear noncoding...

Customizable process design for collaborative geographic analysis

Zaiyang Ma, Min Chen, Zhong Zheng, Songshan Yue, Zhiyi Zhu, Beichen Zhang, Jin Wang, Fengyuan Zhang, Yongning Wen & Guonian Lü
Collaborative geographic analysis can lead to better outcomes but requires complicated interactions among participants, support resources and analytic tools. A process expression with explicit structure and content can help coordinate and guide these interactions. For different geographic problems, the structure and content of collaborative geographic analysis are generally distinct. Since the process structure embodies the pathway of problem-solving and the process content contains the information flow and internal interactions, both the structure and the content...
