Abstract: Provided herein are recombinant circular RNAs comprising at least one protein-coding nucleic acid sequence, wherein the protein-coding nucleic acid sequence encodes a reprogramming factor (e.g., a transcription factor), wherein the reprogramming factor is Oct3/4, Klf4, Sox2, Nanog, Lin28, c-Myc, or L-Myc, or a fragment or variant thereof. Also provided herein are methods of producing induced pluripotent stem cells (iPSC), the method comprising contacting a somatic cell with at least one of the recombinant circular RNAs described herein and maintaining the cell under conditions under which a reprogrammed iPSC is obtained.

Abstract: Methods, compounds and compositions for promoting motor neuron survival and the treatment of a neurodegenerative disorders such as Spinal Muscular Atrophy (SMA) are described herein.

Abstract: Methods and compositions related to a novel cellular pathway, the redox/Fyn/c-Cbl pathway, include a variety of aspects. Provided herein are agents that selectively interrupt the pathway and methods of using the same. Also provided are screening methods used to identify a pro-oxidation toxicant or other agents and stimuli that affect the redox/Fyn/c-Cbl pathway. Methods of testing oxidation levels by evaluating aspects of the pathway are also provided.
