Article Abstract
Genetic complexity and heterogeneity have made drug discovery difficult in human malignancies. In the past few years, we aimed to find vulnerabilities in therapy-resistant and refractory acute myeloid leukemia (AML) through integrative analyses of genomic data, clinical information, and results from in vivo/in vitro cell biological assays. Through analyses, we found that the cells of patients with AML show distinct sensitivity/resistance to small inhibiting molecules for anti-apoptosis and cell cycle/division. In particular, AML cells harboring the IDH1/2 mutations were highly sensitive to BCL-2 inhibition, while inhibition of IAP proteins resulted in efficient elimination of AML cells with varied FLT3, NRAS, and CBL mutations. Linking AML-initiating events with appropriate therapeutic strategies through cellular and genomic analyses might be further translated into nonmyeloid malignancies and solid tumors in the future.

Complex chromosomal changes in Acute Myeloid Leukemia (AML) are highly heterogeneous, with disease progression shaped by both the number and nature of abnormalities. Rarely do, multiple unrelated clones with independent chromosomal changes coexist at diagnosis. Present study showcases a comprehensive characterization of two cytogenetically distinct complex clones in AML, driven by non-cyclic and chromoplexy mechanisms, highlighting their co-existence with key molecular alterations (TP53, NF1, DNMT3A, TET2) along with their potential contribution to clonal evolution.

Background: Following SARS-CoV-2 infection, ~10-35% of COVID-19 patients experience long COVID (LC), in which debilitating symptoms persist for at least three months. Elucidating biologic underpinnings of LC could identify therapeutic opportunities.
Methods: We utilized machine learning methods on biologic analytes provided over 12-months after hospital discharge from >500 COVID-19 patients in the IMPACC cohort to identify a multi-omics "recovery factor", trained on patient-reported physical function survey scores.
Background: Nucleophosmin 1 (NPM1) mutations represent one of the most frequent genetic alterations in acute myeloid leukemia (AML). However, the prognostic significance of concurrent molecular abnormalities and clinical features in NPM1-mutated AML remains to be fully elucidated.
Methods: We retrospectively analyzed 73 adult AML patients with NPM1 mutations.
Background: This study aimed to identify the diagnostic and prognostic ability of serum miR-411-3p in patients with acute myeloid leukemia (AML).
Methods: Blood samples were collected from 60 AML patients and 60 healthy controls to measure serum miR-411-3p and thereafter discuss its potential clinical value.
Results: Serum miR-411-3p was decreased in AML patients and was even lower in those with M4/M5 subtypes or high white blood cell count or adverse cytogenetic risk.
Background: Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive form of peripheral T-cell lymphoma, accounting for 1 - 2% of non-Hodgkin lymphomas. Diagnosis is challenging, and there is no established standard first-line treatment. This case report highlights a rare progression from AITL to therapy-related acute myeloid leukemia (AML-pCT) following cytotoxic chemotherapy.
