Their Story
Dr. Martins is a Group Leader at the MRC Cancer Unit in Cambridge, UK where she leads the “Modeling tumor development and therapy” research program. Her lab focuses on the identification and targeting of the mechanisms responsible for lung tumor progression. Originally from Portugal, she completed her MSc studies in Biology and Genetics at Moscow State University. She then joined the group of Prof Anton Berns at the Netherlands Cancer Institute as a PhD student. During her PhD, she identified new lymphoma-promoting mutations and described novel mechanisms of cooperation between such mutations.

Exploiting the metabolic heterogeneity of mutant KRAS lung tumors to optimize therapy
Principal Investigator: Dr Carla Martins
Lung cancer is the leading cause of cancer related death worldwide and lung adenocarcinoma, a subtype of non-small-cell lung cancer, is its most common histologic subtype. Mutations in KRAS are very frequent (~28%) in lung adenocarcinoma but unfortunately, unlike for other commonly mutated proteins, no mutant KRAS-targeting drugs are currently available. The identification of alternative therapeutic strategies for the efficient treatment of mutant KRAS tumors is therefore a therapeutic priority.
Gene mutations are common events in human cancer and have been a major focus of cancer research. However, sequencing data demonstrate that gene gains and losses are also a common occurrence in cancer but they have been significantly less studied. Our lab recently showed that the number of mutant KRAS gene copies can vary significantly in lung tumors and that the gain of just a single mutant copy (single vs double mutant) has a major effect on tumor models, leading to enhanced metastatic potential and metabolic rewiring. Importantly, we also showed that this metabolic rewiring can potentially be exploited therapeutically.
Our recent data imply that mutant KRAS tumors are heterogeneous and may have different susceptibilities to therapy, that have so far been overlooked. With the support of the LCFA/IASLC Lori Monroe Scholarship in Translational Lung Cancer Research we aim to use our recent findings to improve the targeting of mutant KRAS lung tumors. To achieve this, we propose to use a combination of screening methods to identify therapies that efficiently target each of the two mutant KRAS lung tumor subsets independently (single vs multiple copy). In parallel, we will explore strategies capable of efficiently targeting mutant KRAS lung tumor cells, irrespective of their KRAS gene copy content. Our ultimate goal is to provide innovative therapeutic strategies for patients with mutant KRAS lung adenocarcinoma, and thus radically change disease management for a group of patients urgently in need of therapeutic alternatives.
