Cell death and viability were assessed via flow cytometry, LDH release assays and CCK-8 assays; circPDSS1 stability was determined by agarose gel electrophoresis and actinomycin D treatment; ferroptosis was determined by measuring lipid ROS, MDA, and Fe2+ levels; and key molecular interactions were determined by performing dual-luciferase reporter assays and RIP and RNA pull-down experiments...Mechanistically, circPDSS1 sponged miR-142-3p to upregulate ACSL4 expression, promoting NK cell ferroptosis. Exosomal circPDSS1 derived from GC cells contributes to NK cell ferroptosis by sponging miR-142-3p to increase ACSL4 expression and exacerbate GC.

Drug sensitivity analysis revealed differential responses to 4 drugs between the risk groups, with the 3 ORGs (ACSS2, CLTCL1 and PLD3) showing positive correlations with 2 drugs (BI_2536, Dactinomycin). Additionally, functional experiments confirmed the role of ACSS2 in OS cell behavior. This novel ORG signature not only provides a valuable tool for patient stratification but also offers insights into the biological processes driving OS progression and potential therapeutic targets.

The stability of TBX1 mRNA was analyzed by actinomycin D assay...Collectively, these findings reveal an exosome-mediated piRNA regulatory mechanism that synergistically amplifies VEGFC/VEGFR3 signaling to drive LN metastasis in BC, highlighting piR-hsa-28212 as a potential therapeutic target. Trial Registration: KYLL-2022-338.

Mechanistic studies, including chromatin immunoprecipitation (ChIP), RNA immunoprecipitation (RIP), luciferase reporter, and actinomycin D assay, were conducted to elucidate HIF1-mediated transcriptional regulation of TARDBP and TDP-43-dependent stabilization of thyroid receptor-interacting protein 6 (TRIP6) mRNA...In vivo, TARDBP depletion inhibited tumor growth and downregulated metastasis-related factors in xenograft models. In conclusion, the HIF1-TARDBP-TRIP6 axis promotes CRC malignancy under hypoxia by integrating transcriptional activation and post-transcriptional mRNA stabilization, offering potential therapeutic targets for advanced CRC.

She was managed according to the Chinese Children Cancer Group (CCCG)-WT-2019 protocol, receiving neoadjuvant VAD (vincristine, actinomycin D, and doxorubicin) chemotherapy, followed by staged bilateral nephron-sparing surgery. This highlights the limitations of current histology- and stage-based approaches for specific molecular subtypes. Current evidence supports more aggressive surgical intervention for high-risk cases, but it is essential to balance the need for renal function preservation with the goal of achieving oncological control.

Our results suggested that 8 biomarkers including SLC2A1, SMS, CCNA2, CDC25C, RNASE1, NR3C2, CAT, and ADA were associated with PANoptosis in LUAD. These findings may provide supportive evidence for the prognosis prediction and treatment of LUAD. However, the involvement of these genes in PANoptosis is currently only a hypothesis based on bioinformatics analysis and requires further experimental validation in the future.

METTL3 may drive DE-DLBCL cell cycle progression and RTX resistance by activating MYC and BCL2 transcription via YTHDF2-mediated m6A modification of β-catenin, revealing a novel mechanism of indirect transcriptional regulation in lymphoma and a potential therapeutic target.

TRIM71 may function as a tumor suppressor in CC by regulating Nectin4 expression and influencing Wnt/β-catenin signaling, EMT, tumor progression, and angiogenesis.

The m5C modification level and stability of Snail mRNA were determined by MeRIP and actinomycin D assays...In vivo, AGR2 overexpression promoted tumor growth and EMT through neutrophil-dependent activation of the ALYREF-Snail axis. TAN-secreted AGR2 enhances ALYREF stability, thereby promoting m5C-dependent Snail mRNA stabilization and sustaining EMT and CRC progression.
