Through a literature review, the author also investigates the effect of the hyperlipidemic state on cancer, focusing on carcinoma and vascular endothelial growth factor (VEGF), as well as the RAS-RAF-MEK pathway, which is a target for tyrosine kinase inhibitors, in order to reveal the molecular mechanism of chlorambucil metronomic chemotherapy. Here, MAP2K7 is linked to cancer.
