RNA splicing is frequently dysregulated in tumors. Aberrant RNA splicing can alter tumor metabolism, highlighting the need to elucidate the alternative splicing events that shape the metabolic landscape. In this study, we identified exon skipping in Ste20-like kinase (SLK) that results in a variant isoform (SLKv), which promotes glycolysis in tumor cells.

Current examples of photo-induced aggregation predominantly occur in solution, but the solvent-ubiquitous as it is-is often overlooked as a potential participant in the aggregation process. In this study, photo-induced hydrous organic aggregates (HOA) are reported based on a hydrophobic nitroaromatic compound (NPAC).

The Phase III TOPAZ-1/KEYNOTE-966 study demonstrated chemo-immunotherapy (CIT) as a significant advancement, potentially replacing traditional chemotherapy for advanced biliary tract cancer. Ferroptosis is a crucial process that affects cancer cell survival and therapy resistance.

Herein, a strategy of lone-pair-mediated multiple through-space interactions (TSIs) is proposed to availably induce RTP. By incorporating heteroatoms to facilitate through-space n-n and n-π interactions, the lone pairs are delocalized throughout the structure, resulting in the dense splitting of the excited-state energy levels.

Characterized by remarkable self-renewal and adaptability, CSCs can transition dynamically between stem-like and differentiated states in response to external stimuli, a process termed "CSC plasticity." This adaptability underpins their resilience to therapies, including immune checkpoint inhibitors and adoptive cell therapies (ACT).

Herein, a feasible strategy is pioneered by installing large-volume encumbrances in a confined space to intensify the repulsive interactions arising from overlapping electron densities. The experimental results, including smaller coordinate displacement, reduced reorganization energy, and suppressed internal conversion, demonstrate that the repulsive interactions assist in the inhibition of radiationless deactivation.

Conventional neuronal tracers suffer from restrictions such as limited penetration depth, high immunogenicity, and inadequacy for long-term and imaging. In this context, we introduce an aggregation-induced emission luminogen (AIEgen), MeOTFVP, engineered for enhanced neuronal tracing and imaging.

Background: N4-acetylcytidine (ac4C) represents a novel messenger RNA (mRNA) modification, and its associated acetyltransferase N-acetyltransferase 10 (NAT10) plays a crucial role in the initiation and progression of tumors by regulating mRNA functionality. However, its role in hepatocellular carcinoma (HCC) development and prognosis is largely unknown. This study aimed to elucidate the role of NAT10-mediated ac4C in HCC progression and provide a promising therapeutic approach.

Results: By performing adenoviral-mediated transfection, CCK-8 analyses, F-actin staining, transwell analyses, luciferase reporter analyses and Western blotting, we observed that TGF-β promoted cytostasis and partial epithelial-mesenchymal transition (EMT) in LPCs. In addition, we confirmed that TGF-β activated the Smad and MAPK pathways, including the Erk, JNK and p38 MAPK signaling pathways, and revealed that TGFβ-Smad signaling induced growth inhibition and partial EMT, whereas TGFβ-MAPK signaling had the opposite effects on LPCs.
