MTHFD1L promoted TSCC tumorigenesis in vivo. (A) MTHFD1L knockdown suppressed TSCC cells (CAL-27 and SCC-15 cells) growth in a mouse xenograft. Images of the thyroid cancer cell tumor xenograft from each mouse (n = 5 mice/group). (B,C) Tumor volumes and weights were analyzed. *P < 0.05. (D) The expression of MTHFD1L, Ki67 and Cleaved Caspase 3 in tumor tissues was analyzed by IHC staining. (E) Quantification of the proliferation index (Ki67 staining) and apoptosis index (Cleaved caspase-3 staining) in tumor sections.
