SOX11 and ductal breast carcinoma in situ: To investigate the role of SOX11 in breast cancer progression, we used the pINDUCER21 system to stably transduce DCIS.com cells, an invasive cell line from the MCF10A breast cancer progression series, so that SOX11 was expressed only when induced with Doxycycline (DOX) (referred to as iSOX11 cells) (Figure 1A–B).
