HSDL2 knockdown promotes the proliferation, migration, and invasion of cholangiocarcinoma (CCA) cells by inhibiting ferroptosis. A–D Cell Counting Kit-8 assay (A, B) and colony formation assay (C, D) were applied to assess the effect of erastin (6 µM), which induces ferroptosis, on cell proliferation. (E, F) A transwell assay was applied to assess the effect of erastin (6 µM) on cell migration and invasion. Data are presented as mean ± SD (n=3). **p < 0.01 and ***p < 0.001
