Although the role of miR-205 has been widely elucidated, the function of its host gene (MIR205HG) is yet to be clarified. We have recently investigated whether this gene is a simple endorsement for miRNA production or it may act independently, demonstrating its action as nuclear long noncoding RNA able to control basal-luminal differentiation in the human prostate context, thus deserving the reannotation as LEADR, Long Epithelial Alu-interacting Differentiation-related RNA. Here, we describe the loss and gain of function approaches experimentally used to modulate LEADR expression, and the bioinformatic procedures employed to analyze microarray data in our published article “LEADeR role of miR-205 host gene as long noncoding RNA in prostate basal cell differentiation” . The high reproducibility of replicates, the strong concordance with a validation technique, and the coherent behavior observed for differentially expression features, both in terms of single genes and deregulated pathways, not only support the quality of the data, but also endorse their potential reuse. Very relevant are the diverse silencing and overexpression strategies employed (all of which analyzed in multiple biologically independent replicates), which should allow other scientists to analyze our dataset for the specific purpose of their research, may it be the study of MIR205HG function as miRNA host gene, the investigation of its miRNA-independent biological role or again the dissection of Alu sequence involvement in the mechanism of action of long noncoding RNAs, which is a hot topic in the field.
