Rescigno et al. [56] demonstrated that DHA differentially regulated the activation of extracellular signal-regulated kinase 1/2 (ERK1/2) and signal transducers and activators of transcription 3 (STAT3) pathways as well as cell cycle regulators such as p21 and p53 in breast cancer cell lines. Here, MAPK3 is linked to breast carcinoma.
