JUN and neoplasm: Tumor cells co-cultured with stearyl carnitine (acylcarnitine 18:0) and triglycerides showed enhanced cell migration (Fig. 1E) and increased phosphorylation of c-Jun NH2-terminal kinases (p-JNK), which is a powerful stress-induced protein regulating lipid metabolism and an important promoter in GBC (Fig. 1F) [25–28].
