Figure 5. G bodies containing PFKL form in hypoxic mammalian cells.
(A) Pfk2p homolog, PFKL, forms granules in HepG2 cells maintained in 1% oxygen for 24 h. (B) Time course of PFKL granule formation under hypoxic conditions. HepG2 cells were kept in 1% oxygen for indicated times (1, 3, 8, and 24 h). As a control, cells were cultured under normoxic conditions. (C) Formation of PFKL bodies is dependent on RNA. RNaseA treatment of cells maintained in 1% oxygen for 24 h decreases PFKL bodies compared to vehicle. (A–C) All cells were fixed and stained with anti-PFKL antibody to examine granule formation. All scale bars 10 μm. [See also Figure S8]
