    Redox Regulation of m6A Methyltransferase METTL3 in β-Cells Controls the Innate Immune Response in Type 1 Diabetes

    Scientists reported that N6-methyladenosine (m6A) was an adaptive β-cell safeguard mechanism that controlled the amplitude and duration of the antiviral innate immune response at type 1 diabetes onset.

    AbstractGraphical Abstract

    The ATR Inhibitor Ceralasertib Potentiates Cancer Checkpoint Immunotherapy by Regulating the Tumor Microenvironment

    Researchers showed that modeling of intermittent ceralasertib treatment in mouse tumor models revealed CD8+ T-cell dependent antitumor activity, which was separate from the effects on tumor cells.

    Modulating Tumoral Exosomes and Fibroblast Phenotype Using Nanoliposomes Augments Cancer Immunotherapy

    Investigators showed that cancer cell–targeted nanoliposomes that inhibited sequential steps of exosome biogenesis and released from lung cancer cells block the differentiation of lung fibroblasts into cancer associated fibroblasts.

    IL-37 Dampens Immunosuppressive Functions of MDSCs via Metabolic Reprogramming in the Tumor Microenvironment

    The authors established a human leukocyte antigen-I-matched humanized patient-derived xenograft hepatocellular carcinoma (HCC) model and three murine orthotopic HCC models to study the function of IL-37 in the tumor microenvironment.

    Abstract

    RUNX1 Promotes Angiogenesis in Colorectal Cancer by Regulating the Crosstalk between Tumor Cells and Tumor Associated Macrophages

    Researchers investigated the RUNX1 mediated crosstalk between tumor cells and M2 polarized tumor associated macrophages (TAMs) in colorectal cancer, as well as its relationship with neoplastic angiogenesis.

    MD Anderson Tried — and Failed — to Resolve Research Credit Dispute between Two Scientists, New Documents Show

    Early last year, MD Anderson Cancer Center leadership had a contentious dispute between one of its most powerful researchers and a junior scientist over authorship, credit, and charges of verbal abuse. High-ranking officials at the cancer center tried — and failed — to resolve the feud.
