In terms of promoting cancer, evidence suggests that palmitate may increase carcinogenesis by regulating DNA damage and inflammation [43], induce invasion of pancreatic cancer cells through TLR4/ROS/NF-κB/MMP-9 pathway [44], and increase colorectal cancer cell proliferation in a β2-adrenergic receptor-dependent manner [45]. Here, TLR4 is linked to familial pancreatic carcinoma.
