LNCTSI and ovarian cancer: In ovarian cancer cells, PTAR overexpression stimulates the EMT process, increases the migration and invasion of tumoral cells, and decreases E-cadherin expression via the PTAR/miR-101/ZEB1 axis; the in vivo results have demonstrated that PTAR knockdown substantially decreases tumor growth and increases the protein expression of E-cadherin (Liang et al., 2018[67]).
