Since we found that gain or loss of LSD1 respectively elevated or reduced the expression of Vimentin in cervical cancer cells (Figure 4A–4C), we next performed chromatin immunoprecipitation (ChIP) to investigate whether LSD1 could bind to the promoter of the mesenchymal gene Vimentin to modify histones and thus enhance gene expression. Here, KDM1A is linked to cervical cancer.
