Cell-line specific role of Cathepsin B in triple-negative breast cancer growth, invasion and response to chemotherapy

bioRxiv Cancer Biology | |

Cathepsins are papain-family cysteine proteases known to play a cell-intrinsic role in protein degradation in the lysosome, as well as in digesting ECM and surface proteins after being secreted. Both of these functions are known to mediate pro-tumorigenic effects of CTSB in a range of cancers. Here, we specifically investigate the role of CTSB in TNBC, an aggressive subtype of…
