Article Title: Stefin B and Cystatin C Deficiency Suppresses Tumor Growth and Alters Tumor Microenvironment in a Breast Cancer Model

doi: 10.3390/cells15040360

Figure Lengend Snippet: Effect of stefin B and cystatin C deficiency on proliferation and cell death. ( A ) Cell proliferation in primary tumors was determined through immunodetection of Ki67 in PyMT;WT and PyMT;DKO mice at 14 weeks of age. Representative images and quantification of Ki67-positive cells as a percentage of total cells in PyMT;WT (n = 11) and PyMT;DKO (n = 10) tumors. Ki67 index was calculated from 10 high-power fields per tumor using computer-assisted data analysis in ImageJ. Differences were analyzed using Student’s t -test. ( B ) Cell death in primary tumors from PyMT;WT and PyMT;DKO mice at 14 weeks of age was determined through TUNEL assays. Representative images and quantification of TUNEL-positive cells as a percentage of total cells in PyMT;WT (n = 9) and PyMT;DKO (n = 8) tumors. The TUNEL+ index was calculated from 10 high-power fields per tumor using computer-assisted data analysis in ImageJ. Differences were analyzed using Student’s t -test.
