Calpain-1 Expression in Triple-Negative Breast Cancer: A Potential Prognostic Factor Independent of the Proliferative/Apoptotic Index

Figure 1

Detection of calpain-1 protein in TNBC tissues. Representative immunostaining photomicrographs of high, medium, and low calpain-1 expression [(a) high expression, (b) medium expression, (c) low expression, and (d) negative control (non-TNBC tissue)]. Photomicrographs are shown at ×40 magnification and a scale bar of 20 μm.
