Indolent infections in patients with hematologic malignancy: A single-center experience screening for tuberculosis and strongyloidiasis prior to cytotoxic therapy in Boston.

Individuals with hematologic malignancy have increased risk of latent tuberculosis infection (LTBI) reactivation and (SS) dissemination. However, screening prior to chemotherapy or corticosteroids is not routine. We conducted a LTBI and SS screening intervention amongst patients with hematologic malignancies.

Cdc73 protects Notch-induced T-cell leukemia cells from DNA damage and mitochondrial stress.

Activated Notch signaling is highly prevalent in T-cell acute lymphoblastic leukemia (T-ALL), but pan-Notch inhibitors showed excessive toxicity in clinical trials. To find alternative ways to target Notch signals, we investigated cell division cycle 73 (Cdc73), which is a Notch cofactor and key component of the RNA polymerase-associated transcriptional machinery, an emerging target in T-ALL. Although we confirmed previous work that CDC73 interacts with NOTCH1, we also found that the interaction in T-ALL was context-dependent and facilitated by the transcription factor ETS1.
