DNM1L and ovarian cancer: 3′RACE revealed that ovarian cancer cells express multiple Drp1 transcripts, including mRNAs with alternatively spliced exons 16 and 17, differential 3′UTR lengths, and short transcripts that terminate after exon 14 (ΔC-Ex14) and in intron 17 (ΔC-In17) at predicted alternate polyadenylation sites (Fig. 1C,D; Appendix Fig. S1A,C).
