The MAP kinase (Ras/MEK/ERK) and PI3K/Akt/mTOR oncogenic signaling pathways are central regulators of KRAS-mediated transformation. Molecular reciprocity between the Ras/MEK/ERK and PI3K/Akt/mTOR pathways provides cancer cells with the ability to evade treatment when targeting only one pathway with monotherapy. Multi-kinase

Apolipoprotein (Apo)A-I, the major lipid-binding protein of high-density lipoprotein, can prevent autoimmunity and suppress inflammation in hypercholesterolemic mice by attenuating lymphocyte cholesterol accumulation and removing tissue-oxidized lipids. However, whether ApoA-I mediates immune-suppressive or anti-inflammatory effects under normocholesterolemic conditions and the
