SATB2 and head and neck squamous cell carcinoma: To further investigate whether SATB2 could inhibit the proliferation and tumor progression ability of LSCC cells (HEp2) and head and neck squamous carcinoma (HNSCC) cell lines (Tca8113), we established stable HEp2 cell line and Tcs8113 cell line that expressed SATB2 (HEp2-SATB2 or Tca8113-SATB2) or empty vector (HEp2-plncx2 or Tca8113-plncx2) (Figure 4A & 4B).
