SDHD and cervical cancer: qPCR analysis revealed diminished SDHC and SDHD expression in cervical cancer cells after direct cell–cell contact with Th17 cells (Fig. S4A; 20–52% reduction) and stronger reduced expression of SDHC (31–50% reduction, light blue bars) and SDHD expression (65–82% reduction, dark blue bars) in three different cervical cancer cells after stimulation with CM of Th17 cells (Fig. 4A).
