ALOXs and GPR32 involvement in GC angiogenic response. (A) Tumor growth curves of AGS shCTR, shALOX5 (three clones) and shALOX15 (three clones) xenografts in immunodeficient mice. *p < .05 compared to shCTR xenografts. (B) Representative images and quantification (five fields/sample) of the proliferation index (Ki-67), vessel density (CD31), and apoptotic rate (Cleaved Caspase 3), assessed by immunohistochemistry, of shCTR, shALOX5, and shALOX15 cell xenografts harvested 28 d post-inoculation. *p < .05 compared to shCTR xenografts. (C) ALOX15 and ALOX5 mRNA expression levels of 295 patients affected by gastric adenocarcinoma stratified for disease-free and overall survival status. *p < .05 between the two groups. (D) Tumor growth curves of AGS shCTR and shGPR32 xenografts (average of three clones) cells in immunodeficient mice *p < .05 compared to shCTR xenografts. (E) Representative images of the vessel density (CD31), assessed by immunohistochemistry, of shCTR and shGPR32 AGS cell xenografts harvested 28 d post-inoculation.
