DROSHA and lung cancer: In a recent work, Rotunno et al. [63] showed that the GTAATC haplotype in RNASEN, coding for Drosha, connected with lung cancer-specific reduced survival; moreover, a variant allele of rs640831 was significantly associated with RNASEN reduced mRNA expression and with changes in the levels of particular microRNAs only in adenocarcinomas but not in SqCC samples.
