MCM7 and neoplasm: By also taking in consideration the miRNA-DNA and miRNA-mRNA associations previously discussed, a picture could be delineated in which genomic aberrations could contribute to the establishment of the transcriptional phenotype of basal-like tumours by altering the expression levels of miR-17-92 and miR-106b-25 miRNAs (along with that of their respective host genes c13orf25 and MCM7) which, in turn, decrease the transcript levels of luminal-specific gene signatures.
