(B) Steady state levels of progranulin (GRN) and ephrin-A1 (EFNA1) in T24 and UMUC-3 cells; mean ±SEM, n = 3. (C) Micrographs from the human protein Atlas depicting representative images of normal bladder and low or high-grade urothelial carcinomas. (D) EphA2 expression levels in bladder cancer tissues using IHC on a bladder cancer TMA. (E) Quantification of EphA2 expression in tissues using ImageJ; bladder, n = 27; T1-T4 urothelial carcinomas, n = 123; ***p<0.001.

Techniques Used: Expressing, Western Blot
Figure Legend Snippet: Progranulin evokes EphA2 phosphorylation. Serum-starved T24 cells were exposed to progranulin (150 nM, 15 min) and immunoprecipitated with anti-EphA2 antibodies. Coomassie-stained bands of interest were trypsin-digested and analyzed by LC-MS/MS on a Q Exactive™ Plus mass spec. The mass spec data were probed against the UniProt human database for STY phosphorylation. False discovery rate for peptides/site identifications was set at 1%. (A) Modifications of various residues shown as the sum of MS peptides intensities. (B) EphA2 schematic showing the location of phosphorylated residues. (C-D) Western immunoblots of serum-starved T24 cells exposed to 150 nM progranulin using several Phospho-specific and total antibodies. (E) Western immunoblots of serum-starved 5637 cells after progranulin stimulation ±specific inhibitors for PI3K pathway (LY294002, 20 μM) or Erk1/2 (U0126, 10 μM). (F) Phospho-EphA2 (Ser897) assessed by immunoblot in UMUC-3/shScr (control) and UMUC-3/shPGRN cells. (G) Inhibition of EphA2 kinase activity blocks progranulin-induced phosphorylation. Western immunoblots of serum-starved T24 cells exposed to Ephrin-A1-Fc (2.1 nM) or progranulin (150 nM) for 15 min ±ALW-II-41–27 (1 μM), and probed with Phospho-EphA2 (Ser897) and EphA2 antibodies.

Figure Legend Snippet: EphA2 is required for progranulin-evoked activity and cisplatin sensitivity. (A) EphA2 was depleted in UMUC-3 cells by siRNA approaches and EphA2 expression levels were assessed by immunoblot with anti-EphA2 polyclonal antibodies and normalized over β-actin content. Densitometric analysis was performed using ImageJ (National Institutes of Health) and expressed as arbitrary units. (B) Motility assays in Boyden chambers ±progranulin, ***p<0.001. (C) Anchorage-independent growth in soft-agar was performed as described in Materials and Methods ***p<0.001. (D) Cell survival as assessed by a Colorimetric Cell Cytotoxicity Assay Kit at various cisplatin concentrations. Mean ±SD; n = 3 biological replicates run in duplicates. **p<0.005; ***p<0.001.
Techniques Used: Activity Assay, Expressing, Western Blot, Cytotoxicity Assay
