Experimental details

Fig. 6 EHD2 promotes HCC growth and macropinocytosis in vivo. a Left: 6-8-week-old male nude mice were orthotopically implanted with luciferase-labeled MHCC97L-EV, -EHD2-KO#4, and -EHD2-KO#13 cells into the livers. HCCs were harvested 6 weeks after implantation. Middle: Livers (HCCs) harvested from the tumor-bearing mice (top) and bioluminescent imaging of lung metastases (bottom). Right: Confocal images demonstrate ex vivo dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in HCCs (top). Tumor volumes, bioluminescence of lung metastases, and macropinocytic indexes of HCC tissues were quantified (bottom). n = 5 biologically independent samples. b Left: HDTVi was performed in 8-10-week-old male wild-type C57BL/6 N mice to induce Ehd2 EV ; Tp53 KO ; c-Myc OE (EV) and Ehd2 KO ; Tp53 KO ; c-Myc OE (KO) HCCs. Middle: Image of livers (HCCs) was shown (top). Western blots demonstrate EHD2 protein expressions in EV and KO HCC tissues (bottom). Right: Confocal images show ex vivo dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in HCCs (top). Liver weights and macropinocytic indexes of HCCs (bottom). n = 5 biologically independent samples. c Confocal images show dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in orthotopic HCC tissues in nude mice. In vivo dextran labeling was performed by IV injection. n = 5 biologically independent samples. d Confocal images show dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in HCC tissues in HDTVi model

Experimental details

Fig. 7 HIF-1/EHD2 induces macropinocytosis to support HCC growth in hypoxic conditions. a Transgenic strategy for generation of C57BL/6 N EHD2 germline KO ( Ehd2 -/- ) mouse. Exon3 of mouse Ehd2 was spliced in Ehd2 -/- mice. b Left: Gel picture shows PCR products from WT ( Ehd2 +/+ ) and KO ( Ehd2 -/- ) alleles in Ehd2 +/+ , Ehd2 -/- , and Ehd2 +/- mice. Right: Western blots demonstrate EHD2 expression in liver tissues from 8-week-old Ehd2 +/+ , Ehd2 +/- , and Ehd2 -/- male mice. Results were representative for three independent experiments with similar results. c Top: Image of livers ( Tp53 KO ; c-Myc OE HCCs) from Ehd2 +/+ and Ehd2 -/- mice. Middle: Confocal images show ex vivo dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in Ehd2 +/+ and Ehd2 -/- HCC tissues. Bottom: Liver weights and macropinocytic indexes from Ehd2 +/+ and Ehd2 -/- mice. n = 6 biologically independent samples. d Top: Image of livers ( Keap1 KO ; c-Myc OE HCCs) from Ehd2 +/+ and Ehd2 -/- mice. Middle: Confocal images show ex vivo dextran uptake/macropinosomes (red) and nuclei (DAPI, blue). Bottom: Liver weights and macropinocytic indexes from Ehd2 +/+ and Ehd2 -/- mice. n = 5 biologically independent samples. e Top: Image of livers (DEN/CCl 4 HCCs) was shown. Middle: Confocal images demonstrate ex vivo dextran uptake/macropinosomes (red) and nuclei (DAPI, blue) in HCC tissues from Ehd2 +/+ and Ehd2 -/- mice. Bottom: Liver weights and macropinocytic indexes from Ehd2 +/+ and Ehd2 -/- mice. n
