Abstract: Aspects of the disclosure provide compositions and methods for reversible expression of a target gene. In some aspects, the disclosure provides nucleic acids comprising multiple pairs of recombinase sites, each pair having first and second members flanking an inverted expression cassette encoding a target gene.

Abstract: The present disclosure provides, in some embodiments, methods for culturing and expanding hematopoietic stem cells (HSPCs) comprising a genomic modification associated with clonal hematopoiesis (CH). These cultured and expanded HSPCs are used, in some embodiments, to identify genes that promote CH, to identify inhibitors of CH, and to inhibit CH.

Abstract: Provided herein are methods of treating a nonhematopoietic malignant tumor in a patient and methods of prognosing a nonhematopoietic malignant tumor in a patient, comprising administering to the patient a therapeutically effective amount of an agent that preferentially kills or inhibits proliferation or activity of leukocytes relative to nonhematopoietic cells.

Abstract: Disclosed are systems and methods for retrieving, for a patient with a medical condition, a structured dataset and an unstructured dataset, the structured dataset comprising demographic and clinical data, and the unstructured dataset comprising a report with free-form text of a clinician with respect to a medical procedure (e.g., a test). Analysis may comprise applying natural language processing to the free-form text in the report to generate a plurality of health indicators for the patient. Categorizations corresponding to the medical condition may be generated, and a treatment regimen determined based on drug orders in the structured dataset. Survival modeling may be applied to generate a prediction corresponding to a survival of the patient following administration of a treatment to the patient for the medical condition. A treatment may be selected and administered based on the prediction.

Abstract: The presently disclosed subject matter relates to the use of one or more biomarkers to evaluate the likelihood that an EZH2 inhibitor would produce an anti-cancer effect in a subject. It is based, at least in part, on the discovery that loss of BAP1 results in the upregulation of EZH2 expression and activity. In a specific non-limiting embodiment, the method comprises obtaining a sample of the cancer from a subject, and determining, in the sample, the expression level of an BAP1 biomarker, where if the BAP1 biomarker is absent or expressed at lower level in the cancer as compared to a reference control level, then administering a therapeutically effective amount of an EZH2 inhibitor to produce an anti-cancer effect.
