Silencing these genes induced cell proliferation inhibition and apoptosis in bladder urothelial carcinoma cells., DGCR8-mediated cleavage of snoRNAs was independent of Drosha, suggesting the involvement of DGCR8 in cellular complexes with other endonucleases. Binding of DGCR8 to cassette exons is a new mechanism for regulation of alternatively spliced isoforms., A subset of Lin28 mRNA targets are destabilized in a Drosha-dependent manner., Drosha protein potentially plays an important role in breast cancer progression., Data indicate that tumour sample showed a significantly higher Drosha expression versus normal mucosa, while Dicer levels did not differ., miRNA regulatory effect is a heritable trait in humans; a polymorphism of the DROSHA gene contributes to the observed inter-individual differences., Primary microRNA structure reveals deviations from canonical double-stranded RNA structure in the stem adjacent to the Drosha cut site.
