These results demonstrate that the overactivation of Akt plays a critical role in MEK inhibitor primary and acquired resistance and implicate combined Akt/MEK inhibition as a potentially useful treatment for RAS/BRAF-mutated colorectal cancer.

of RAF and MEK signaling, several MEK inhibitors have been approved for patients harboring BRAF alterations4. Trametinib23 (2013) and binimetinib24 (2018) were approved for the treatment of metastatic melanoma with BRAF V600E/K mutations. Combination therapies of BRAF plus MEK inhibitors have been approved in melanoma and NSCLC.

pathway, including NRAS and BRAF constitute approximately 4% and 8% of CRCs, respectively [4]. Thus, targeting the downstream substrate MEK in KRAS, BRAF or NRAS mutated tumors stands out as a potential target in CRC. Several selective inhibitors of MEK have entered clinical trial evaluation [7];

RAF and MEK inhibitors are now approved and used in the clinic. There is now much interest in targeting at the level of ERK1/2 for a variety of reasons. First, since the pathway is linear from RAF-to-MEK-to-ERK then ERK1/2 are validated as targets per se. Second, innate resistance to RAF or MEK inhibitors involves relief of negative

strated higher phosphorylation levels of MEK and ERK. The higher Braf expression with enhanced phos-phorylation of MEK and ERK in CD26 cells sug-gested a possible therapeutic effect of Raf265 on CD26 CSCs.

The most striking clinical responses to inhibitors of BRAF, MEK, and EGFR have been observed in melanoma and lung cancers where RAS pathway activation is . exacerbates resistance to MEK inhibition; however, combined MEK and MET inhibition overcame therapy resistance [6]. Importantly, these results demonstrated that NF1-related MPNSTs maintain .

Methods: We examined the molecular and functional effects of single and combined BRAF (dabrafenib), pan-RAF (RAF265), MEK (trametinib) and EGFR/HER2 (lapatinib) inhibition, using Western Blot and conservative isobologram analysis to assess functional synergism, and explored genetic determinants of synergistic interactions.

The RAS-RAF-MEK-ERK pathway is altered in 40% of all human cancers, mainly due to mutations in BRAF ( 10%) and its upstream activator RAS ( 30%) [14]. MEK inhibitors were the first drugs developed, but despite their high potency and selectivity largely disappointed in the clinic [4,15].

Combined therapy with BRAF and MEK inhibitors has shown benefit in PFS and response rate, compared with monotherapy, delaying the appearance of alterations involved in resistance (13). Mechanisms of resistance to MAPK pathway inhibition can be subdivided in two groups: MAPK-dependent and MAPK-independent. Into BRAF/MEK/ERK dependent reactivation,

BRAF is a component of MAPK pathway, which relays proliferative signals, triggered at cell membrane receptors, through the cytoplasm to the nucleus. e mitogen-activated protein kinase MEK is also com-monly overactivated in melanoma; thus, a combination of BRAF and MEK inhibitors was conceived as dual mecha-
