Summary: The study found that exposure to PM SRM1648a increased LC3II expression and autophagosome accumulation in HUVECs, indicating impaired autophagic degradation function. Through experiments and analysis, it was revealed that the detrimental effects of PM SRM1648a on lysosomal function lead to the blockage of autophagic flux, ultimately resulting in endothelial cell damage.

Summary: This study evaluated the antiproliferative effects of six azo-dyes and TMZ on human glioblastoma cells and found that azo-dyes showed stronger cytotoxic effects at equimolar concentrations compared to TMZ. Methyl Orange exhibited the highest potency in inhibiting cell growth. These findings suggest that azo-dyes may be a potential source of agents for cancer treatment.

Summary: Chemoresistance is a challenge in the treatment of glioblastoma (GBM), and the activity of O6-methylguanine-DNA methyltransferase (MGMT) and signal transducer and of transcription 3 (STAT3) have been linked to GBM resistance. Resveratrol (Res) inhibits tumor growth and improves chemosensitivity by targeting STAT3 signaling. This study found that Res effectively improved chemosensitivity of GBM cells to temozolomide (TMZ) and downregulated STAT3 activity, leading to inhibition of cell proliferation, migration, and induction of apoptosis. The combination therapy of Res and TMZ also reversed TMZ resistance and decreased MGMT and STAT3 levels. Therefore, Res may be an ideal candidate for combined chemotherapy with TMZ in GBM.

Summary: It has been found that methadone, a drug containing opioids, can increase the sensitivity of glioblastoma cells to temozolomide by increasing intracellular calcium concentration, oxidative stress, and DNA damage. This study provides evidence for the potential value of methadone in the treatment of glioblastoma with temozolomide and sheds light on the molecular mechanism of synergistic action of these two drugs.

Summary: Riluzole demonstrates significant growth-inhibitory effects on all GBM cell lines in a time- and dose-dependent manner. It synergistically enhances the antitumor effect of TMZ in MGMT-positive GBM cell lines, while suppressing MGMT expression and TMZ-induced MGMT upregulation. Combinatorial TMZ/riluzole treatment significantly suppresses tumor growth in an intracranial MGMT-positive GBM model, suggesting it as a promising therapeutic regimen for MGMT-positive GBMs.

Summary: The study reveals the role of NRF2 in modulating ferroptosis in glioblastoma cells, as well as its correlation with ABCC1 expression. Moreover, high levels of NRF2 result in collateral sensitivity and contribute to GSH depletion when the system xc(-) is blocked. These findings suggest that ferroptosis induction could be a potential therapeutic strategy to reverse drug resistance in gliomas.

Summary: In this study, the researchers found that SNX10 was selectively expressed in glioblastoma stem cells (GSCs) compared with non-neoplastic neural stem cells (NSCs). SNX10 was essential for GSC survival and promoted GSC proliferation and stem cell signaling pathways through posttranscriptional regulation of PDGFR tyrosine kinase. Targeting SNX10 expression decreased GSC viability and self-renewal capacity. High expression of SNX10 correlated with poor prognosis in glioblastoma patients.

Summary: CRNDE is a poor prognosis factor for GBM patients, upregulated in TMZ-resistant patients, and closely associated with chemotherapeutic response to TMZ treatment. Knockdown of CRNDE significantly reduces glioma cell viability and proliferation, enhances cell apoptosis, and improves sensitivity to TMZ treatment.

Summary: Exosomes, nano-sized extracellular vesicles secreted by cells, have been explored as carriers to transport compounds across the blood-brain barrier for targeting the central nervous system. This study compared different methods for loading exosomes with natural compounds of varying molecular weights and investigated their efficacy both in vitro and in vivo. The results showed a positive correlation between the efficiency of compound loading and its molecular weight. Moreover, certain exosome-encapsulated natural compounds were found to effectively reduce levels of neurodegenerative disease mutant proteins. Additionally, exosome-encapsulated-neferine was shown to improve motor deficits and decrease beta-amyloid levels in the brain. This research provides a rationale for using exosomes to target blood-brain barrier permeability and treat neurodegenerative diseases.

Summary: In this study, researchers used CEST magnetic resonance imaging to monitor molecular changes in hematoma after intracerebral hemorrhage (ICH). The results showed that this technique could noninvasively monitor and guide treatments. Specifically, the researchers observed differences in contrasts between rNOE and amide proton transfer at different time points and locations, and these contrast changes were highly consistent with histological findings. Based on the results, CEST magnetic resonance imaging can be used to monitor molecular changes and related tissue characteristics during ICH and treatment.

Summary: This study proposes a parallel cascade using aryl alcohol oxidase (PeAAOx) from Pleurotus eryngii and unspecific peroxygenase (AaeUPO) from Agrocybe aegerita to convert aromatic primary alcohols into high-value aromatic aldehydes. Key factors such as enzyme dosage, pH, and temperature were investigated. The study evaluates the universality of PeAAOx coupled with AaeUPO cascade catalysis for the synthesis of aromatic aldehyde flavor compounds.
