Exposure to MC-LR activates the RAF/ERK signaling pathway, leading to renal inflammation and tissue damage in mice

Exposure to microcysatin-LR (MC-LR) is known to result in kidney damage, however the underlying mechanisms involved in MC-LR-initiated renal injury are not known. Thus, the aim of this study was to examine the effects of exposure to MC-LR on human embryo kidney (HEK 293) cell
