Cross-Species Comparison of the Pan-RAF Inhibitor LY3009120's Anti-Tumor Effects in Equine, Canine, and Human Malignant Melanoma Cell Lines. (PubMed, Genes (Basel))
The anti-tumor effects of LY3009120 were observed in nine melanoma cell lines, indicating the potential feasibility of experimental trials with LY3009120. The present study reveals that the irradiation-resistant canine metastasis cells (cRGO1.2) harboring the NRAS p.G13R mutation are significantly LY3009120-sensitive, while the equine metastases-derived eRGO6 cells show significant resistance to LY3009120, which make them both valuable tools for studying resistance mechanisms in comparative oncology.

Clonal Medicine Targeting DNA Damage Response Eradicates AML (ASH 2023)
The "clonal attack" by DDR inhibitors shifts the paradigm of genotoxic therapies from those using non-discriminative cytotoxic drugs to those selectively attacking DDR vulnerabilities in AML clones with minimal harm to normal cells. Since clonal heterogeneity and DNA damage are hallmarks of cancer, the "clonal attack" may be broadly applicable to the quest for cancer cure.

Small nucleotide, copy number and structural variants cooperate to hijack driver genes in extramedullary progression of myeloma (IMW 2023)
The MAPK DM, high TMB and persistent genomic instability suggest roles for MAPK-targeted therapies, immunotherapies and DNA damage repair pathway inhibitors, respectively, in EMD. Recurrent codon 61 mutations in RAS suggest a specific role in EMD progression.

Describing the molecular landscape of extramedullary multiple myeloma using whole genome sequencing: Insights into pathology and therapeutic targets (AACR 2023)
MAPK DM were frequent in EMD, and detectable in ctDNA, suggesting roles for both MAPK-targeted therapies and for ctDNA as a biomarker in these patients. A high TMB was identified in patients lacking a MAPK driver mutation; immunotherapy should be considered in this subgroup.

Acute Myeloid Leukemia with CEBPA Mutation: Next-Generation Sequencing-Based Computational Approach For Enhancing the Diagnosis of Patients with Potential Germline CEBPA Mutated Predisposition (USCAP 2023)
Recognizing and referring patients with possible germline mutations for appropriate genetic evaluation and testing provides insight into best patient care strategies along with education and testing opportunities for family members. Leukemia based NGS panels may aid as screening tools for detecting potential pathogenic germline variants.

Prevalence and patterns of mutations in RAS/RAF/MEK/ERK/MAPK signaling pathway in colorectal cancer in North Africa. (PubMed, BMC Cancer)
KRAS mutated CRC patients in North Africa have been identified with incidence closer to the European figures. Beside established anti-CRC treatment, better understanding of the causality of CRC can be established by combining epidemiology and genetic/epigenetic on CRC etiology. This approach may be able to significantly reduce the burden of CRC in North Africa.

Enhanced BRAF engagement by NRAS mutants capable of promoting melanoma initiation. (PubMed, Nat Commun)
Molecular dynamics simulations, combined with cell-based protein-protein interaction studies, reveal that melanomagenic NRAS mutants form intramolecular contacts that enhance BRAF binding affinity, BRAF-CRAF heterodimer formation, and MAPK > ERK signaling. Along with the allelic series of conditional mouse models we describe, these results establish a mechanistic basis for the enrichment of specific NRAS mutants in human melanoma.

Liquid biopsy (LB)-based comprehensive genomic profiling (CGP) of circulating tumor DNA (ctDNA) for the evaluation of patients with myeloid neoplasms. (ASCO 2022)
LB identified clinically relevant genomic alterations in myeloid neoplasia, offering a powerful tool that may be used pre- or post-treatment when CGP of the buffy coat, marrow, or tissue is infeasible. Given its low limit of detection, LB can also identify low-level emerging or persistent subclones, which may facilitate monitoring and minimal residual disease testing.

PTEN loss-of-function mutations prevalent in HRAS-mutant cancers results in resistance to targeted therapy (AACR 2022)
‘RASless’ (KRASlox/HRASKO/NRASKO) mouse embryonic fibroblasts (MEFs) were obtained that in the presence of 600nM tamoxifen (4OHT) resulted in a KRAS knock-out...Combined treatment of HRASG13R/PTEN MEFs with the PIK3CB-specific inhibitor AZD8186 and tipifarnib sensitized cells in non-4OHT (IC50- 100nM:100nM Tipifarnib:AZD8186) and 4OHT (IC50- 100nM:10nM Tipifarnib:AZD8186) conditions... Co-altered mutations of MAPK, PI3K or RTK effectors are found more commonly in HRAS than in KRAS or NRAS-mutant cancers. Co-alteration of PTEN preferentially associated with HRAS-mutations in NSCLC. Deletion of PTEN resulted in resistance to FTI targeted therapy in vitro.

Diverse alterations associated with resistance to KRAS(G12C) inhibition. (PubMed, Nature)
Here we evaluated matched pre-treatment and post-treatment specimens from 43 patients treated with the KRAS(G12C) inhibitor sotorasib...A subset of patients in our cohort acquired oncogenic KRAS, NRAS or BRAF mutations, and resistance in this setting may be delayed by co-targeting of ERK signalling intermediates. These findings merit broader evaluation in prospective clinical trials.
