Summary: Alterations in the RTK/RAS/RAF pathway are a characteristic feature of lung adenocarcinoma (LUAD). A study using whole-genome sequencing of 85 cases initially identified as RPA(-) revealed that around 33% of cases were actually RPA(+). The remaining cases showed genetic mutations associated with tumor suppressor deletions and genome instability.

Summary: The KRAS/ERK pathway phosphorylates DICER1, leading to its nuclear translocation, and phosphomimetic Dicer1 promotes tumorigenesis in mice. However, the mechanisms by which phospho-DICER1 regulates tumor progression are not fully understood. In this study, we discovered that phosphorylated nuclear DICER1 (phospho-nuclear DICER1) promotes late-stage tumor progression in mice with oncogenic Kras, independent of microRNAs (miRNAs) and epithelial-to-mesenchymal transition (EMT). Our findings suggest that phospho-nuclear DICER1 plays a role in lineage reprogramming of tumor cells to mediate lung cancer progression.

Summary: Splicing factor mutations, especially in U2AF1, are common drivers of myeloid malignancies, affecting the splicing process and leading to intron retention and exon exclusion. In addition, U2AF1 mutations directly influence the components of stress granules, which are involved in adaptive oncogenic strategies in cancer cells.

Summary: Research indicates that deletion of the wild-type allele in hematopoietic cells expressing U2AF1(S34F) heterozygous mutation is lethal, confirming the dependence of mutant U2AF1 cells on the expression of wild-type U2AF1 for survival. Leukemia cells carrying mutant U2AF1 are more sensitive to reduced wild-type U2AF1 expression, suggesting a potential therapeutic strategy for selectively targeting the wild-type U2AF1 allele in mutant cells.

Summary: The study reveals the crucial role of U2AF1 in normal hematopoiesis, as its deletion leads to loss of hematopoietic stem/progenitor cells and increased DNA damage. RNA sequencing analysis shows significant alterations in genes related to HSC maintenance, cell proliferation, and DNA damage response in U2AF1-deficient HSPC, as well as splicing alterations in genes important for HSPC function.

Summary: Somatic mutations in spliceosome genes are found in around 50% of patients with myelodysplastic syndromes (MDS), a myeloid malignancy associated with low blood counts. The mutant splicing factor U2AF1(S34F) alters hematopoiesis and mRNA splicing in mice. Alternative splicing of spliceosome genes has been implicated in hematopoietic abnormalities.

Summary: Cis-regulatory elements play crucial roles in tissue-specific gene expression and phenotype evolution. Mutations in promoters and enhancers may drive species adaptations to environments. TRIM72, a highly conserved protein involved in energy metabolism, shows varying levels of expression in primate hearts, with mutations in the promoter being responsible for these differences. Accelerated rates of evolution in the TRIM72 promoter suggest positive selection influenced by changes in cardiac physiology after species divergence. Mutations in the TRIM72 promoter account for differential expression in human and rhesus macaque hearts, affecting genes involved in oxidative phosphorylation, mitochondrial respiration, and cardiac energy capacity. Phylogenetic regression analyses indicate a correlation between high cardiac TRIM72 expression and heart rate in mammals.

Summary: Genomically-informed therapy requires consideration of the functional impact of genomic alterations on protein expression and/or function. The MD Anderson Precision Oncology Decision Support (PODS) team developed an actionability classification scheme that categorizes VUS as either Unknown or Potentially actionable based on their location within functional domains and/or proximity to known oncogenic variants. Our results demonstrate that rule-based actionability classification of VUS can identify patients more likely to have actionable variants for consideration with genomically-matched therapy.

Summary: DNA replication alteration is frequently observed in lung adenocarcinoma (LUAD) progression. The ORC, especially ORC1/6, has important prognostic and expression significance for LUAD patients. Furthermore, the ORC cooperatively promotes LUAD development by driving DNA replication, cellular senescence, and metabolic processes.

Summary: KRASG12C inhibitors have greatly improved the clinical management of KRASG12C-mutant lung adenocarcinoma patients, but resistance develops rapidly. In this study, genetically engineered mice were used to compare the efficacy and resistance between genetic ablation and pharmacological inhibition of mutant Kras. Results showed that Kras ablation effectively regressed tumors and prevented resistant cells, while treatment with sotorasib, a selective KRASG12C inhibitor, led to limited antitumor response and rapid onset of resistance. Unlike human tumors, resistance in mice was not due to mutations in RAS signaling pathways, but rather amplification of mutant Kras allele and activation of xenobiotic metabolism pathways.

Summary: This study investigates the resistance of anti-CD19 chimeric antigen receptor (CAR19) T cells in relapsed/refractory large B-cell lymphoma (r/rLBCL) patients. By analyzing longitudinal samples from two independent cohorts, it identifies multiple gene alterations associated with resistance, such as B cell identity genes (PAX5 and IRF8), immune checkpoint genes (CD274), and genes affecting the tumor microenvironment (TMEM30A). It also reveals that somatic tumor alterations affect CAR19 therapy at various levels, including CAR19 T cell expansion, persistence, and tumor microenvironment. These findings have implications for improving CAR T cells and personalized therapeutic approaches.

Summary: We explored the value of circulating tumor DNA (ctDNA) for early outcome prediction, measurable residual disease monitoring, and surgery-free CNSL identification. CtDNA was detectable in 78% of pretreatment plasma and 100% of CSF samples. Presence of ctDNA in pretreatment plasma was associated with shorter progression-free survival and overall survival. Monitoring ctDNA during treatment identified patients with poor prognosis. We developed a machine learning approach for biopsy-free CNSL identification from ctDNA.

Summary: Machine learning is increasingly used in clinical oncology to diagnose cancers, predict patient outcomes, and inform treatment planning. This review focuses on recent applications of machine learning across the clinical oncology workflow, including medical imaging and molecular data obtained from liquid and solid tumor biopsies for cancer diagnosis, prognosis, and treatment design. Key considerations in developing machine learning for the distinct challenges posed by imaging and molecular data are discussed. The review also examines machine learning models approved for cancer-related patient usage by regulatory agencies and discusses approaches to improve the clinical usefulness of machine learning.

Summary: Follicular lymphomas (FL) are characterized by BCL2 translocations, often detectable in blood years before FL diagnosis, but also observed in aging healthy individuals, suggesting additional lesions are required for lymphomagenesis. CREBBP KAT domain mutations were the most commonly observed precursor lesions, distinguishing patients developing FL from healthy adults with or without BCL2 rearrangements. These mutations can be detected years before clinical diagnosis and may help discriminate individuals at risk for lymphoma development.

Summary: In DLBCL, a positive interim PET scan predicts treatment failure, and combining it with the presence of an IgM gammopathy can improve prediction. The combination of interim PET and IgM gammopathy can dichotomize the population into high-risk and low-risk groups with significantly different outcomes. Only the interim PET result and IgM gammopathy status were significantly associated with outcome, making them important factors in risk-adapted treatment strategies.

Summary: Lung cancer is the leading cause of cancer deaths worldwide, and mutations in the TP53 gene are linked to poor prognosis in lung adenocarcinomas (LUADs). This study reveals that p53 suppresses LUAD by promoting alveolar type 1 (AT1) differentiation. Through direct DNA binding, chromatin remodeling, and induction of AT1 cell characteristic genes, p53 induces an AT1 differentiation program during tumor suppression. Additionally, p53 plays a role in alveolar regeneration after injury by regulating AT2 cell self-renewal and promoting transitional cell differentiation into AT1 cells.
