Infiltrating plasma cells maintain glioblastoma stem cells through IgG-Tumor binding.

Glioblastoma is a highly aggressive primary brain tumor with glioblastoma stem cells (GSCs) enforcing the intra-tumoral hierarchy. Plasma cells (PCs) are critical effectors of the B-lineage immune system, but their roles in glioblastoma remain largely unexplored. Here, we leverage single-cell RNA and B cell receptor sequencing of tumor-infiltrating B-lineage cells and reveal that PCs are aberrantly enriched in the glioblastoma-infiltrating B-lineage population, experience low level of somatic hypermutation, and are associated with poor prognosis.

Prospects for PARG inhibitors in cancer therapy.

Poly(ADP-ribose) glycosylhydrolase (PARG) is an enzyme involved in hydrolyzing the ribose-ribose bonds present in poly(ADP-ribose) (PAR), which are primarily found in the nucleus. Along with poly(ADP-ribose) polymerase (PARP), PARG regulates the level of PAR in cells, playing a crucial role in DNA maintenance and repair processes. Recent studies have revealed elevated levels of PARG in various cancers, such as breast, liver, prostate, and esophageal cancers, indicating a link to unfavorable cancer outcomes.

Identification of Renal Ischemia-Reperfusion Injury Subtypes and Predictive Model for Graft Loss after Kidney Transplantation Based on Programmed Cell Death-Related Genes.

Introduction: Ischemia-reperfusion injury (IRI) is detrimental to kidney transplants and may contribute to poor long-term outcomes of transplantation. Programmed cell death (PCD), a regulated cell death form triggered by IRI, is often indicative of an unfavorable prognosis following transplantation. However, given the intricate pathophysiology of IRI and the considerable variability in clinical conditions during kidney transplantation, the specific patterns of cell death within renal tissues remain ambiguous.
