Summary: Acrolein, a reactive aldehyde, is generated during lipid peroxidation in a hypoxic environment and can form bonds with cysteine residues, leading to functional changes in proteins and immune suppression. Neutrophils play a critical role in the immune response, with proinflammatory N1 neutrophils exerting antitumor effects and anti-inflammatory N2 neutrophils supporting tumor growth. Glioma is characterized by hypoxia, immune cell infiltration, and an immunosuppressive microenvironment. Previous studies have shown that neutrophils exhibit an antitumor phenotype in early glioma development but transition to a tumor-supporting role as the tumor progresses. However, the mechanism behind this switch in neutrophil phenotype remains unclear. This study demonstrates that acrolein production in glioma cells inhibits neutrophil activation and induces an anti-inflammatory phenotype by directly interacting with AKT and inhibiting its activity. Moreover, higher levels of acrolein adducts in tumor tissue are associated with poorer prognosis in glioblastoma patients, and high-grade glioma patients exhibit increased serum acrolein levels and impaired neutrophil functions. These findings highlight the importance of acrolein in suppressing neutrophil function and contributing to the switch in neutrophil phenotype in glioma.

Summary: In this study, a newly developed tool called GenOx was used to identify hypoxia regulated long non-coding RNAs (lncRNAs) and discover Hypoxia Response Element (HRE) and Hypoxia Ancillary Sequence (HAS) motifs in their promoter regions. Molecular, functional, and interactome-based analyses showed that these hypoxia-relevant lncRNAs play important roles in primary tumors and cell-line models. TP53TG1 and SNHG1 were identified as highly relevant lncRNAs in glioma progression and downregulation of SNHG1 in hypoxia was associated with worsened prognosis.

Summary: The study aimed to investigate whether ionizing radiation could induce ferroptosis in glioma cells and whether CA9 knockdown could enhance the killing effect of ionizing radiation on hypoxic glioma cells through ferroptosis. The results showed that X-ray could induce lipid peroxidation and ferroptosis markers expression in U251 and GL261 glioma cells. Knockdown of CA9 significantly altered the expression of iron regulation-related proteins and enhanced X-ray-induced ferroptosis and radiosensitivity in hypoxic glioma cells. Enhancing ferroptosis in glioma cells could promote the efficacy of radiotherapy for glioma.

Summary: L-Carnosine has shown broad-spectrum anticancer activity against human glioma cells U87 and U251 by inhibiting glutamine synthetase expression, leading to decreased proliferation, migration, and invasion capabilities. This effect was independent of oxygen levels and may offer new treatment strategies for gliomas by targeting tumor metabolism.

Summary: The study showed a positive correlation between PD-L1 and HIF-1α in glioma, with their overexpression associated with poor survival. HIF-1α was found to induce PD-L1 expression under hypoxic conditions, which could be abrogated by inhibiting HIF-1α. Combination therapy of HIF-1α inhibitor and anti-PD-L1 antibody demonstrated enhanced tumor growth suppression and improved immune activation.

Summary: RLIP76 is a hypoxia-inducible protein that promotes glycolysis in glioma cells. It activates glycolytic proteins GLUT1 and LDHA by binding to HIF-1a and regulating its stability, accelerating glycolysis in hypoxia. Furthermore, RLIP76 plays a necessary role in enhancing glycolysis in glioma development.

Summary: Ruthenium(II)-arene complexes have attracted attention for their potential use in cancer therapy. Two new complexes were characterized by IR, NMR, and elemental analysis. The crystal structure and intramolecular interactions of one complex were determined using X-ray crystallography and Hirshfeld surface analysis. Theoretical analysis was performed on the cationic part of the complexes, and the chosen level of theory was validated by reproducing experimental spectra. The compounds exhibited radical scavenging activity and high activity against prostate and colon cancer cell lines.

Summary: Xerostomia, or dry mouth, is mainly caused by hypofunction of the salivary glands due to various factors. Current treatment methods are not very effective and regenerative medicine using dental pulp stem cells shows promise. Dental pulp stem cells can differentiate into different cell types and have immunomodulatory effects. However, more clinical studies are needed to fully understand their potential for salivary gland regeneration.
