ABSTRACT
"A recent discovery that dietary fatty acids can interact with the human genome by regulating the amount and/or activity of transcription factors has opened a whole new line of research aimed to molecularly corroborate the ant-cancer benefits of the olive oil-based Mediterranean diet and the underlying mechanisms. Our most recent findings reveal that oleic acid (OA; 18:1n-9), the main olive oil's monounsaturated fatty acid, can suppress the overexpression of HER2 (erbB-2), a well-characterized oncogene playing a key role in the etiology, invasive progression and metastasis in several human cancers."

ABSTRACT
"CONCLUSIONS: i) These findings reveal that the omega-3 PUFA ALA suppresses overexpression of HER2 oncogene at the transcriptional level, which, in turn, interacts synergistically with anti-HER2 trastuzumab- based immunotherapy. ii) Our results molecularly support a recent randomized double-blind placebo-controlled clinical trial suggesting that ALA may be a potential dietary alternative or adjunct to currently used drugs in the management of HER2-positive breast carcinomas. iii) Considering our previous findings demonstrating the <<HER2 upregulatory actions>> of the omega-6 PUFA linolenic acid (LA; 18:2n-6) and the <<HER2 down-regulatory actions >> of the omega-3 PUFA docosahexaenoic acid (DHA; 22:6n-3) and of the omega-9 monounsaturated fatty acid oleic acid (OA; 18:1n-9), it is reasonable to suggest that a low omega-6/omega-3 PUFA ratio and elevated MUFA levels, the two prominent <<fat features>> of the <<Mediterranean diet>>, should be extremely efficient at blocking HER2 expression in breast cancer cells."
