HTT and neuroblastoma: To address the specificity of such alteration of miR-146a, miR-125b and miR-150 in the presence of poly Q aggregates, mutated exon1 of HTT gene that translated to N-terminal HTT with 83 Q was exogenously expressed in four different cell lines viz., Neuro2A (mouse neuroblastoma cell line), STHdhQ7/HdhQ7 (mouse sriatal cells having two copies of full length HTT with 7Q), SH-SY5Y (human neuroblastoma cell line) and HeLa cells (human cells derived from cervical tumours) and the expression of twenty two miRNAs were studied in these cell models (Table S1).
