We used two cervical cancer cell lines with stably knocked down ATXN1, HeLashATXN1-#1 and HeLashATXN1-#2 cells, that were generated using a lentivirus system and stably expressed ATXN1-specific short hairpin RNAs (shRNAs), as previously described [10]. The gene discussed is ATXN1; the disease is cervical carcinoma.
