DDX50 cooperates with STAU1 to effect stabilization of pro-differentiation RNAs.

Glucose binding can alter protein oligomerization to enable differentiation. Here, we demonstrate that glucose binding is a general capacity of DExD/H-box RNA helicases, including DDX50, which was found to be essential for the differentiation of diverse cell types. Glucose binding to conserved DDX50 ATP binding sequences altered protein conformation and dissociated DDX50 dimers.

Tumor Lysis Syndrome in Acute Myeloid Leukemia Patients Treated With a Venetoclax Based Regimen.

Venetoclax with hypomethylating agents (HMA) is the standard of care for acute myeloid leukemia (AML) in patients ineligible for intensive chemotherapy and is associated with tumor lysis syndrome (TLS). TLS prophylaxis and the use of Cairo Bishop versus Howard diagnostic criteria are not standardized. Here we report TLS prophylaxis and incidence in a retrospective cohort of 100 consecutive AML patients treated with venetoclax and HMA.

SARS-CoV-2 resistance analyses from the Phase 3 PINETREE study of remdesivir treatment in nonhospitalized participants.

Remdesivir inhibits the SARS-CoV-2 RNA-dependent RNA polymerase (RdRp; Nsp12). Here, we conducted viral resistance analyses from the Phase 3 PINETREE trial of remdesivir in nonhospitalized participants at risk of severe COVID-19. Nasopharyngeal swabs (collected at baseline [Day 1], Days 2, 3, 7, and 14) were eligible for analysis if their viral load was above the lower limit of quantification for the RT-qPCR assay (2228 copies/mL).

Imaging of electric-field-induced domain structure in DyMnO nanocrystals.

Multiferroic materials that exhibit interacting and coexisting properties, like ferroelectricity and ferromagnetism, possess significant potential in the development of novel technologies that can be controlled through the application of external fields. They also exhibit varying regions of polarity, known as domains, with the interfaces that separate the domains referred to as domain walls. In this study, using three-dimensional (3D) bragg coherent diffractive imaging (BCDI), we investigate the dynamics of multiferroic domain walls in a single hexagonal dysprosium manganite (h-DyMnO ) nanocrystal under varying applied electric field.

Lisocabtagene Maraleucel for Relapsed/Refractory Large B-Cell Lymphoma: A Cell Therapy Consortium Real-World Analysis.

Lisocabtagene maraleucel (liso-cel) is an autologous CD19-directed CAR T cell therapy approved for the treatment of relapsed/refractory large B-cell lymphoma (LBCL). We present a multicenter retrospective study evaluating safety, efficacy, and resource utilization of liso-cel in the standard-of-care setting. Patients received commercial liso-cel at 7 US medical centers and patient selection, toxicity management, and disease assessment followed institutional practices.
