Small RNA deep sequencing and qRT-PCR were employed to determine RNA types and content. A sequence-specific RNA-capture magnetic bead system was developed to enrich specific glycoRNAs, such as U2 and U4. Glycan components were analyzed using liquid chromatography-mass spectrometry. CCK-8, adhesion, ki67, TUNEL staining assays were used to evaluate cell viability, adhesion, proliferation and apoptosis. Glioma cells were found to be rich in glycoRNAs, predominantly small RNAs, with U2 and U4 being particularly abundant. These glycoRNAs primarily contained fucosylated and sialylated complex glycans. The depletion of cell-surface glycoRNAs at the observed time point significantly inhibited glioma cell viability and proliferation, without altering cell adhesion or apoptosis levels. This study underscored the significant role of glycoRNAs in glioma proliferation and provided a foundation for further research into their potential as novel biomarkers and therapeutic targets for glioma. Glioma cells U87 and LN229 showed significant enrichment in glycoRNAs, predominantly small RNAs, with U2 and U4 being particularly abundant and specific.

These epithelial cancers include cutaneous squamous cell carcinoma (cSCC), the second-most common cancer. cSCC is highly invasive and accounts for an estimated 15,000 deaths each year. We identified SRCAP, a chromatin remodeler that regulates the chromatin occupancy of the histone H2A variant H2A.Z, as a frequently mutated gene in cSCC. Analysis of cSCC mutations in epithelial cancers identified a hotspot truncating mutation in SRCAP, which removes 42% of the protein sequences after amino acid 1879. While SRCAP mutations have been previously connected to the pathogenesis of Floating-Harbor syndrome (FHS), these typically occur downstream, with a hotspot mutation leading to protein truncation after amino acid 2444. We found that expressing the SRCAP-1879 truncation in an HRas-CDK4-driven cSCC model was sufficient to increase proliferation, impair terminal differentiation, and accelerate invasion. Mechanistically, the expression of SRCAP-1879 in primary human keratinocytes was sufficient to dysregulate genes crucial for carcinogenesis (e.g., proliferation, differentiation, and motility) without altering H2A.Z occupancy. In particular, the expression of SRCAP-1879 truncation led to strong induction of the matrix metalloproteinase MMP9 expression level, accompanied by increased keratinocyte cell motility, which was sensitive to matrix metalloprotease inhibition. In contrast, the expression of the SRCAP-FHS truncation did not increase but instead reduced cell motility as well as the expression of MMP9.

Our findings demonstrate that Pimozide increases peroxisome numbers and that peroxisomal deficiency significantly enhances Pimozide-induced cell death.

As key metabolic hubs interconnected with mitochondrial metabolism, peroxisomes support energy homeostasis, thereby preventing Pimozide-induced cell death.

Fadraciclib decreased phosphorylation of RNA polymerase II, indicating suppression of RNA transcription. The tumor growth inhibitory effect of fadraciclib plus encorafenib was synergistic. Fadraciclib decreased Rb phosphorylation, inhibited cell cycle progression, and promoted DNA damage as evidenced by cleavage of PARP, increased pH2AX (ser139), and activation of p53.
