Correction: Discovery of CTCF-Sensitive Cis-Spliced Fusion RNAs between Adjacent Genes in Human Prostate Cells

The term FKPM (fragments per kilobase of transcript per million fragments sequenced) is incorrect throughout. The correct description should be FPKM (Fragments Per Kilobase Of Exon Per Million Fragments Mapped). The following references are omitted in the article: Two references are omitted from the second sentence of the second paragraph in the Introduction. The sentence should read: In recent years, several studies using the EST database and RNA-sequencing approaches have identified fusion RNAs involving neighboring genes, which were named “transcription-mediated gene fusions”, “tandem chimerism” and “conjoined genes” by various groups [9,10], (Prakash et al., 2010), (Parra et al., 2006). The references are: Prakash T, Sharma VK, Adati N, Ozawa R, Kumar N, Nishida Y, et al. (2010) Expression of conjoined genes: another mechanism for gene regulation in eukaryotes. PloS one 5: e13284. Parra G, Reymond A, Dabbouseh N, Dermitzakis ET, Castelo R,, Thomson TM, et al. (2006) Tandem chimerism as a means to increase protein complexity in the human genome. Genome research 16: 37–44. Two references are omitted from the seventh sentence of the first paragraph under the subheading “Classifications of the fusion RNAs” in the Results section. The sentence should read: cBioPortal query on TP53 showed only 14.7% alteration in TCGA in the prostate cancer set. Consistently, LNCaP cells contain wild type TP53 [18], (Cerami et al., 2012), (Gao et al., 2013). The references are: Cerami E, Gao J, Dogrusoz U, Gross EB, Sumer SO, Aksoy BA, et al.

Two references are omitted from the first sentence of the first paragraph under the subheading “CTCF binding in between parental genes” under the subheading “Further validation for cis-SAGe fusion RNAs in the Results section. The sentence should read: “We used two methods to evaluate the evidence for CTCF binding in-between the 38 pairs of parental genes: 1) visual examination of CTCF binding sites generated by ENCODE on the UCSC genome browser (Fig. 3B and Table 1), and 2) searching for CTCF binding site on the Insulator Database, CTCFBSDB (Ziebarth et al., 2013), (Bao et al., 2008).
