Integrative genomic analysis of DLBCL identifies immune environments associated with bispecific antibody response.
Blood
January 2025
University of Chicago, Chicago, Illinois, United States.
Most diffuse large B-cell lymphoma (DLBCL) patients treated with immunotherapies such as bispecific antibodies (BsAb) or chimeric antigen receptor (CAR) T cells fail to achieve durable treatment responses, underscoring the need for a deeper understanding of mechanisms that regulate the immune environment and response to treatment. Here, an integrative, multi-omic approach was applied to multiple large independent datasets in order to characterize DLBCL immune environments, and to define their association with tumor cell-intrinsic genomic alterations and outcomes to CD19-directed CAR T-cell and CD20 x CD3 BsAb therapies. This approach effectively segregated DLBCLs into four immune quadrants (IQ) defined by cell-of-origin and immune-related gene set expression scores.

Deep learning based analysis of G3BP1 protein expression to predict the prognosis of nasopharyngeal carcinoma.

Department of Pathology, the Second Xiangya Hospital, Central South University, Changsha, Hunan, China.
Background: Ras-GTPase-activating protein (GAP)-binding protein 1 (G3BP1) emerges as a pivotal oncogenic gene across various malignancies, notably including nasopharyngeal carcinoma (NPC). The use of automated image analysis tools for immunohistochemical (IHC) staining of particular proteins is highly beneficial, as it could reduce the burden on pathologists. Interestingly, there have been no prior studies that have examined G3BP1 IHC staining using digital pathology.

5-Methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are crucial epigenetic modifications in eukaryotic genomic DNA that regulate gene expression and are associated with the occurrence of various cancers. Here, we combined bisulfite conversion with 4-acetamido-2,2,6,6-tetramethyl-1-oxopiperridinium tetrafluoroborate (ACTBF, TCI) oxidation to develop a label-free and sequence-independent isothermal amplification (BTIA) assay for a genome-wide 5mC and 5hmC analysis. The BTIA strategy can distinguish 5mC and 5hmC signatures from other bases with high sensitivity and good specificity, avoiding sophisticated chemical modifications and expensive protein labeling.

Curr Diab Rep
January 2025
Department of Psychological Sciences, University of California, Merced, CA, USA.
Purpose Of Review: Insulin restriction is commonly studied as a form of disordered eating, but people may restrict insulin for many reasons. This systematic review examined how insulin restriction has been conceptualized and measured, and its associated predictors and outcomes.
Recent Findings: Forty-seven unique articles measured non-specified insulin restriction (IR), insulin restriction specifically for weight control (IRWC), or both.
