Abstract:
N-6-methyladenosine (m(6)A) modification-the most prevalent mammalian RNA internal modification-plays key regulatory roles in mRNA metabolism. Current approaches for m(6)A modified RNA analysis limit at bulk-population level, resulting in a loss of spatiotemporal and cell-to-cell variability information. Here we proposed a m(6)A-specific in situ hybridization mediated proximity ligation assay (m(6)AISH-PLA) for cellular imaging of m(6)A RNA, allowing to identify m(6)A modification at specific location in RNAs and image m(6)A RNA with single-cell and single-molecule resolution. Using m(6)AISH-PLA, we investigated the m(6)A level and subcellular location of HSP70 RNA103-m(6)A in response to heat shock stress, and found an increased m(6)A modified ratio and an increased distribution ratio in cytoplasm under heat shock. m(6)AISH-PLA can serve in the study of m(6)A RNA in single cells for deciphering epitranscriptomic mechanisms and assisting clinical diagnosis.
