I'm very delighted to share with you the first output from our RAS precision medicine team in Manchester. This has been almost 6 years of work with my great colleague and an incredible scientist, Professor Angeliki Malliri. Congratulations to Will who has seen this through and continues to thrive in his postdoc. Manchester Cancer Research Centre; Cancer Research UK (CRUK) https://lnkd.in/dDcH3gbS In this report, we have contrasted KRAS G12C and G12D in driving NSCLC tumorigenesis, observing that KRAS G12D confers increased potency at tumour formation, associated with increased engagement with the PI3K-AKT-mTOR axis. Comparing with mutant-specific combination targeting in G12C models, we found that co-targeting KRAS G12D and AKT through pharmacological inhibition has a synergistic impact in KRAS G12D driven models in vitro and in vivo. This work suggests that combination treatment strategies for patients with RAS-mutant cancers should be tailored to the specific KRAS mutant subtype, targeting directly in combination with its downstream signalling programme.
