Glioma patients will inevitably develop resistance to temozolomide (TMZ) leading to tumor recurrence. By comparing genomic differences between primary and recurrent glioma patients, Thioredoxin reductase 1 (TrxR1) was identified as a crucial role in TMZ resistance. Glioma cells elevate the expression level of TXNRD1 to against TMZ-induced reactive oxygen species (ROS), thereby conferring TMZ resistance.

Reduced mitochondrial quality and quantity in tumors is associated with dedifferentiation and increased malignancy. However, it remains unclear how to restore mitochondrial quantity and quality in tumors and whether mitochondrial restoration can drive tumor differentiation. Our study shows that restoring mitochondrial function using retinoic acid (RA) to boost mitochondrial biogenesis and a mitochondrial uncoupler to enhance respiration synergistically drives neuroblastoma differentiation and inhibits proliferation.

This study aimed to utilize the mRNA-lipid nanoparticle (mRNA-LNP) platform to achieve in situ hepatic expression of an interferon-α (IFN-α)/anti-glypican-3 (anti-GPC3) fusion protein (GPA01), enhancing IFN-α targeting and antitumor activity to provide a precision therapy strategy for GPC3-positive hepatocellular carcinoma (HCC). mRNA encoding a GPC-3/IFN-α bispecific fusion protein was designed and synthesized, encapsulated in lipid nanoparticles, and transfected into HCC cell lines (HepG2) for in vitro characterization of protein expression, binding activity, and gene induction. Orthotopic HCC models (HepG2-luc) and subcutaneous tumor model (Hepa 1-6/hGPC3-hi) were established in mice to evaluate tumor growth, survival, and immune cell infiltration following treatment with mRNA-LNP or control agents.

Glioblastoma multiforme (GBM) continues to pose a significant challenge in the field of neuro-oncology primarily because of the limited penetration of therapeutics across the blood-brain barrier (BBB) and the presence of immunosuppressive tumor microenvironments. To address these challenges, a HD-PEG@BM biomimetic nanoplatform (hereinafter referred to as HD-P@BM) is developed that cloaks the near-infrared II photosensitizer HD-PEG (HD-P) inside microglial membranes to enable enhanced BBB penetration and tumor-targeted delivery. In this study, it is found that the microglia-derived membranes enhanced the uptake of nanoparticles by both the glioma cells and tumor-associated microglia.

Background: Connexin (Cx) hemichannels (HCs) contribute to glioblastoma (GBM) progression by facilitating intercellular communication and releasing pro-tumorigenic molecules, including ATP and glutamate.
Methods: The efficacy of abEC1.1, a monoclonal antibody that inhibits Cx26, Cx30, and Cx32 HCs, was assessed in vitro by measuring invasion capability, dye and Ca uptake, glutamate and ATP release in patient-derived GBM cultures or organoids.
