    IDH1/2 Mutations in Lung Cancer: A Closer Look at Their Incidence, Origin, and Clinical Characteristics (AMP 2024)
    IDH1/2 mutations are identified in a small subset of NSCLCs. Our findings suggest that >25% of these mutations are hematopoietic in origin with important implications for diagnosis and management of these patients. Among those with mutations arising from the lung neoplasm, IDH1/2 mutations were primarily seen in conjunction with another driver and were subclonal in nature, suggesting patterns of clonal heterogeneity and evolution.

    Comprehensive Immunogenomic Profiling of IDH1-/2-Altered Cholangiocarcinoma. (PubMed, JCO Precis Oncol)
    Significant differences in GA and immune biomarkers are noted between IDH1/2+ and IDHwt iCCA. IDH1-/2-mutated tumors appear immunologically cold without gLOH. These immunogenomic data provide insight for precision targeting of iCCA with IDH alterations.

    Single-Cell Genomics and Proteomics Reveals Venetoclax-Resistant Monocytic Differentiation of TP53 LOH Clones in TP53 Mutant AML (ASH 2023)
    Patients 1 and 3 received treatment with CD47AB (Magrolimab), 5'-Azacitidine (Aza), and Venetoclax (Ven); Patient 2 received IMGN632 (CD123-targeting ADC), Aza and Ven. Patient 4 received p97 Inhibitor CB-5339; Patient 5 received CD47 inhibitor (ALX148), Aza, Ven... This study establishes a genotype-phenotype connection through single-cell proteogenomic profiling of TP53-mutated AML, describing the clonal evolution and immunophenotypic dynamics during treatment while proposing a potential mechanism of resistance.
