Abstract:
Since calpain 6 is overexpressed in uterine cervical cancer tissue compared to normal tissue, we sought to define the role of calpain 6 during tumorigenesis. We overexpressed calpain 6 or inhibited calpain 6 in human cervical cancer cells (HeLa cells) and human umbilical vein endothelial cells (HUVECs), and measured cisplatin-mediated apoptosis and VEGF-mediated angiogenesis. The results indicated that calpain 6 supported tumorigenesis by inhibiting apoptosis and facilitating angiogenesis. To our knowledge, this result is the first evidence implicating calpain 6 in tumorigenesis, and it reveals calpain 6 as a novel therapeutic target for certain types of cancers.

Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
