B Western blotting confirmed GPRC5A as a hypoxia‐induced protein in SILAC lysates. C Validation of GPRC5A Western blot data using siRNA. *Non‐specific band of ˜60 kDa not depleted by GPRC5A siRNA. D Confocal microscopy showing plasma membrane GPRC5A expression in hypoxic SW620 cells (scale bars: 75 μm). E Western blotting showing GPRC5A upregulation by hypoxia in a panel of colorectal tumour cell lines. F Basal & hypoxia‐induced GPRC5A protein expression was decreased by HIF‐1/2α depletion. G Depletion of HIF‐1β decreased GPRC5A protein upregulation in hypoxia. H Hypoxia mimetic DMOG induced HIF‐1/2α, CA9 and GPRC5A protein expression.

J qRT–PCR demonstrating that HIF‐1/2α depletion decreased GPRC5A induction during hypoxia ( n = 3). GPRC5A was normalised to HPRT (error bars ± SD). K ChIP‐PCR analyses identify HIF‐1α binding to the GPRC5A promoter region containing a putative optimal HRE (error bars ± SD, n = 3). Data information: Asterisks (*) indicate non‐specific band.

a Glioblastoma cells (dsRED C6) co-cultures with either autologous or allogeneic GD2 CAR T and GFP control T cells at 5:1 E:T ratios. After 48 and 72 h tumor viability is calculated by fluorescence assay as reported in “Methods”. Data are shown as mean ± SD from three technical replicates; p values are calculated by unpaired two-tailed t -test. b Representative fluorescence micrographs show clusters of activation and killing activity of GD2 CAR T cells. GFP T cell population show an absence of reactivity of autologous cytotoxic lymphocytes.
