We have previously established and immortalized head and neck PGL cell cultures PTJ64i and PTJ86i from two patients carrying the SDHC c.43 C > T (p.Arg15*) and SDHD c.27delC (p.Val10Phefs*5) mutations, respectively9 (link). PTJ64i and PTJ86i cell lines were cultured in DMEM-F12 (Sigma), supplemented with 10% FBS, at 37 °C, 5% CO2. Sodium dichloroacetate (DCA) and metformin were purchased from Sigma Aldrich. GW6471 was obtained from Tocris Bioscience (Bristol, UK).
