a RT-PCR validation of aberrant splicing of ESRRG in MCF7 cells transduced with Ad-null, Ad-SF3B1WT, and Ad-SF3B1R625H, respectively. The higher band corresponds to the cryptic ESRRG transcript and the lower band corresponds to the canonical ESRRG transcript. b, c Sanger sequence of gel-purified fragment showing the aberrant ESRRG transcript in SF3B1R625H cells b, the canonical ESRRG transcript in SF3B1WT cells c. The red dotted lines indicate the location of 21 nucleotides. d Structure of minigene splicing reporters spanning the E5 region of ESRRG. e RT-PCR validation of aberrant splicing of ESRRG in MCF7 cells co-transduced minigene reporter with Ad-null, Ad-SF3B1WT and Ad-SF3B1R625H, respectively. The higher band corresponds to the cryptic ESRRG transcript and the lower band corresponds to the canonical ESRRG transcript. f, g Sanger sequence of gel-purified fragment showing the aberrant ESRRG transcript in SF3B1R625H cells f, the canonical ESRRG transcript in SF3B1WT cells g.
