Article Title: Promotion of breast cancer by the DNPH1 enzyme

doi: 10.1016/j.isci.2026.115227

Figure Lengend Snippet: Overexpression of DNPH1 in human breast tumors (A) DNPH1 mRNA expression in various breast cancer subtypes was analyzed in published microarray data. Mean with standard deviation and statistical significance compared to normal breast tissue are indicated; ∗∗∗∗, p < 0.0001 (one-way ANOVA, Tukey’s multiple comparisons test). (B) High (top quartile) DNPH1 mRNA levels predict reduced survival. Data derived from published microarray experiments ; p < 0.0001 (log rank test). (C) DNPH1 protein expression in human breast cell lines assayed by Western blotting. (D) Examples of immunohistochemical staining with DNPH1 antibodies on matching normal and cancerous breast tissue. Scale bars, 0.1 mm. (E) DNPH1 protein expression was measured by immunohistochemistry in 20 matching normal and cancerous human breast tissues; two-tailed, paired t test.

Article Title: Inhibition of cell surface GRP78 on brain tumors reverses drug resistance and stops cancer stem cell expansion

doi: 10.1016/j.jbc.2026.111146

Figure Lengend Snippet: Cell surface GRP78 colocalizes with ROR1, Cripto, and PD-L1 on late-stage patient GBM tissues but not on normal brain cerebrum tissues. A, three brain tissue microarrays with patient core tissue samples of GBM and normal tissues (#T174T from Biomax.us.) were stained for GBM markers. B, one microarray was stained with 4′,6-diamidino-2-phenylindole (DAPI) ( blue -DNA), and antibodies to cell surface GRP78 ( green -FITC), ROR1 ( red -PE). The last column is an overlay of all three stains to show colocalization. Cores B2 (stage 4 GBM) and C7 (normal cerebrum) are pictured. C, a second microarray was stained with DAPI ( blue -DNA), and antibodies to cell surface GRP78 ( green -FITC), PD-L1 ( red -PE). The last column is an overlay of all three stains to show colocalization. Cores B6 (stage 4 GBM) and C5 (normal cerebrum) are pictured. D, a third microarray was stained with DAPI ( blue -DNA), and antibodies to cell surface GRP78 ( green -FITC), PD-L1 ( red -PE). The last column is an overlay of all three stains to show colocalization. Cores B6 (stage 4 GBM) and C5 (normal cerebrum) are pictured. Scale bars represent 400 μm (10×). All images are from the same magnification of (10×) 400 μm. GBM, glioblastoma multiforme; GRP78, glucose-regulated protein 78; PD-L1, programed death-ligand 1; ROR1, receptor tyrosine kinase–like orphan receptor-1.
