Detection of Human IL-13 Ra2 antibody by Western Blot.

Detection of Human IL‑13 R alpha2 by Western Blot.

Western blot shows lysates of human placenta tissue and human testis tissue. PVDF membrane was probed with 5 µg/mL of Mouse Anti-Human IL-13 Ra2 Monoclonal Antibody (Catalog # MAB614) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for IL-13 Ra2 at approximately 50-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Evaluation of apoptosis and microvessel density after sunitinib treatment in xenograft model derived from cell lines.MVD was decreased by sunitinib treatment of each xenograft tumor derived from (A) 786-O or (B) Caki-1 subclones regardless of IL13RA2 expression level. MVD was determined from CD31 staining using Image J software. Statistical analysis was performed using the Students’ t-test (*P < 0.01). Immunoblot analysis of (C) 786-O subclones and (D) Caki-1 subclones. IL13RA2 expression was negatively correlated with the phosphorylation of STAT6. Whole cell extracts were immunoblotted using the indicated antibodies. ssDNA staining of xenograft tumors derived from (E) 786-O subclones and (B) Caki-1 subclones treated with sunitinib or vehicle only. Apoptosis was assessed by calculating the ssDNA positivity rate. Statistical analysis was performed using the Students’ t-test (*P < 0.05, **P < 0.01). Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/26114873), licensed under a CC-BY license. Not internally tested by R&D Systems.

Detection of IL-13 R alpha 2 by Western Blot

Overexpression of IL13RA2 leads to acquired resistance to sunitinib and shRNA-mediated IL13RA2 knockdown induces sensitivity to sunitinib.(A) Immunoblot analysis of 786-O subclones infected with retrovirus encoding mock or WT IL13RA2. Whole cell extracts were immunoblotted using the indicated antibodies. Sequential changes in subcutaneous xenograft tumors from 786-O subclones infected with (B) mock or (C) WT IL13RA2 treated with sunitinib and vehicle (control). Each time point represents the mean ± SE of tumor volume in each group. The difference in tumor size between the treatment group and control was statistically significant in 786-O-mock cells but not statistically significant in 786-O-IL13RA2 cells (*P < 0.05, n.s.: not significant; two-way repeated ANOVA). The horizontal arrow bars indicate the periods of sunitinib administration. (D) Immunoblot analysis of Caki-1 subclones infected with lentivirus encoding scrambled or IL13RA2 shRNA. Whole cell extracts were immunoblotted using the indicated antibodies. Sequential changes of subcutaneous xenograft tumors from a Caki-1 subclone infected with (E) scrambled or (F) IL13RA2 shRNA treated with sunitinib and vehicle (control). Each time point represents the mean ± SE of tumor volume in each group. Day 0 is the first day of sunitinib administration 4 weeks after transplantation. The difference in tumor size between the treatment group and control was not significant in Caki-1-sh-scrambled cells but statistically significant in Caki-1-sh-IL13RA2 cells (n.s.: not significant, *P < 0.05; two-way repeated ANOVA). The arrow bars indicate the period of sunitinib administration.

Background: IL-13 R alpha 2

Two type I membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with high affinity. The lower affinity IL-13 binding protein is now referred to as IL-13 R alpha1 and is also known as CD213a. IL-13 R alpha1 combines with IL-4 R alpha to form a high affinity receptor complex capable of transducing an IL-13-dependent proliferative signal. The higher affinity IL-13 binding protein, now referred to as IL-13 R alpha2, does not induce a signal and acts as a decoy receptor.
