Figure Lengend Snippet: A. Knockdown of TAp73 decreases, whereas knockdown of ΔNp73 increases, the expression of p21 and PUMA. The levels of p21, PUMA, and actin were measured in parental MDCK, MDCK-TAp73-KD, and MDCK-ΔNp73-KD cells by Western blotting. B. Generation of MDCK cell lines in which p21 was stably knocked down. Parental MDCK and MDCK-p21-KD cells were mock-treated or treated with camptothecin for 18h and the level of p21 and actin protein was measured by Western blotting. C. Representative microscopic images of parental MDCK and MDCK-p21-KD cells in 2-D cultures. D. Top panel: colony formation assay was performed with parental MDCK or MDCK-p21-KD cells. Bottom panel: the number of colonies was counted and presented as Mean ± S.D. from three separate experiments. E. Wound healing assay was performed with parental MDCK and MDCK-p21-KD cells. Top panel: cell migration was determined by visual assessment of cells migrating into the wound for 24 h using a phase-contrast microscopy. The dashed lines indicate the wound edge. Bottom panel: the time required for would closure was measured and presented as Mean ± s.d. from three separate experiments. F. Representative images of parental MDCK and MDCK-p21-KD cells in 3-D culture for 6 d or 12 d. Scale bar: 50 μM.

Figure Lengend Snippet: A. - D. The levels of β-catenin, E-cadherin, Snail, Twist, and actin were determined by Western blotting with extracts from parental MDCK (A-D), MDCK-TAp73-KD A. , MDCK-p21-KD B. , MDCK-PUMA-KD C. , and MDCK-ΔNp73-KD D. cells. E. The levels of E-cadherin, Snail and Twist transcripts were measured by qRT-PCR in parental MDCK cells and MDCK cells with knockdown of TAp73, ΔNp73, p21 or PUMA. The level of Actin was measured as an internal control. F. A model for the role of p73, p21 and PUMA in MDCK cell morphogenesis.

Article Title: The Ox40/Ox40 Ligand Pathway Promotes Pathogenic Th Cell Responses, Plasmablast Accumulation, and Lupus Nephritis in NZB/W F1 Mice

doi: 10.4049/jimmunol.1700608

Figure Lengend Snippet: Anti-Ox40 agonist mAb treatment exacerbates renal disease and IgM deposition in NZB/W F1 mice. Renal disease monitoring following anti-Ox40 agonist mAb (red) and a control Ig (blue) treatment (10 mg/kg, three times per week for 3 wk) in NZB/W F1 mice. Black arrows (Rx) refer to treatment days. The age and proteinuria status of each cohort (at the time of first treatment) is indicated at the top of each plot. (A) Thirteen-week-old proteinuria-free NZB/W F1 mice at treatment start. (B) Three independent cohorts (21-, 26-, and 27-wk-old) of NZB/W F1 mice with proteinuria 30–100 mg/dl at treatment start. (C) Representative H&E- and PAS-stained kidney sections (left and middle panels) highlighting glomeruli (top panels), periarterial regions (middle panels), and tubulointerstitium (bottom panels). Scale bars, 100 μm. Corresponding disease severity scores (right panels). Group means are plotted in black (n = 36 per group combined). (D) Representative images from frozen kidney sections (left panels) stained for glomerular deposits of IgM (top panel), IgG (middle panel), and C3 (bottom panel). Scale bars, 50 μm. Corresponding signal intensity in the cortex regions is presented as pixel intensity/μM2 of cortex with group mean ± SD from two independent cohorts (n = 25–28 per group, combined) (right panels). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.

Article Snippet: Glomerular IC deposits were visualized on 5-μm acetone-fixed OCT-embedded kidney sections by direct immunofluorescence staining using Alexa Fluor 488–conjugated donkey anti-mouse IgG (cat. no. A-21202; Invitrogen), goat anti-mouse IgM (cat. no. A-21042; Invitrogen), or fluorescein-conjugated goat anti-complement C3 (cat. no. 55510; MP Biomedicals).
