While protein-level functions of NFIL3 are widely explored, the molecular details regarding phospho-signals regulating NFIL3 and their functional significance are underexplored. To interpret the phosphoregulatory patterns of NFIL3, we conducted an extensive literature survey for mass-spectrometry-based cellular phosphoproteomics datasets with representation of NFIL3 phosphosites. From the compiled list of 656 cellular profiles and 116 datasets with differential expression, Ser301 and Ser353 of NFIL3 were identified as the predominant phosphosites, accounting for the majority of NFIL3 phosphosignals. Further, we explored the coregulated phosphosites in the interacting partners and transcription factors associated with NFIL3. With our integrative phosphoproteomics and the IL-4 dependent transcriptome dataset analysis, we report Ser301 and Ser353 as positively co-occurring phosphorylations in NFIL3 that essentially regulate its transcriptional activity. Further, we also unveil Mitogen-activated protein kinase 14 (MAPK14) as a high-confidence upstream kinase that can phosphorylate Ser301.

Comprehensive bioinformatics analysis of cytokine activity, associated pathways, and immune alterations in sepsis is warranted. Using the sepsis dataset GSE26378 from GEO, we analyzed differential cytokine pathway activity with ssGSEA and identified differentially expressed genes (DEGs). Cytokine-related genes (CRGs) were extracted and overlapped with DEGs. Protein-Protein Interaction (PPI) network analysis and functional enrichment were performed on differentially expressed CRGs. Cytokine activity scores and pathway activities were quantified using Gene Set Variation Analysis (GSVA). Immune cell infiltration was assessed with MCP-counter. Machine learning algorithms (Random Forest, LASSO, SVM) identified diagnostic biomarkers, validated using an independent dataset (GSE26440) and ROC analysis. Cytokine/cytokine receptor pathways were significantly upregulated in sepsis. We identified 617 DEGs and 46 differentially expressed CRGs. Cytokine activity scores were significantly elevated in sepsis and strongly correlated with heightened activity in inflammatory pathways (e.g. TLR, IL-1R, NF-κB, JAK/STAT, hypoxia) and metabolic pathways (e.g. glycolysis, PI3K/AKT/mTOR). Immune analysis showed decreased T cells, NK cells, B cells, and cytotoxic lymphocytes, alongside increased neutrophils and endothelial cells; neutrophil infiltration positively correlated with cytokine scores. Machine learning identified four core genes (C3AR1, XCL1, CSF2RA, IL2RB), consistently dysregulated in sepsis across datasets and demonstrating robust diagnostic accuracy.

However, whether IGFBP6 is involved in ferroptosis, a key biological process, in the progression of AS remains unclear. In this study, IGFBP6 expression was downregulated in oxidized low-density lipoprotein (ox-LDL)-treated human umbilical vein endothelial cells (HUVECs). Overexpression of IGFBP6 inhibited reactive oxygen species (ROS) production, reduced Fe2+ concentration and and inflammatory factor levels, and increased Glutathione (GSH) content in ox-LDL-treated HUVECs. Ferrostatin-1 (Fer-1), an inhibitor of ferroptosis, reversed IGFBP6 silencing induced ferroptosis of HUVECs. Mechanistic studies revealed that IGFBP6 is a target of Methyltransferase-like protein 3 (METTL3) that mediates N6-methyladenosine (m6A) modification, and YTH N6-methyladenosine RNA binding protein 2 (YTHDF2) recognizes and promotes METTL3-m6A-mediated IGFBP6 mRNA degradation. Downregulated IGFBP6 reduces its protein level by interacting with GPX4, thereby promoting ferroptosis in HUVECs. In addition, APOE-/- mice fed with a high-fat diet were used as an AS animal model, and the results showed that endothelial cell specific METTL3 knockdown or IGFBP6 overexpression hindered the development of AS in mice.

BMI1 is demonstrated to be downregulated in HSCR tissues compared to normal intestinal tissues, but it is still unclear whether BMI1 is involved in the pathogenesis of HSCR. Here, we found that BMI1 expression was downregulated in HSCR-stenosed segments (HSCR-S) cases compared with HSCR-dilated segments (HSCR-D) or control cases. Pharmacological inhibition of BMI1 using PTC-209 significantly attenuated cell proliferation, migration, and cell cycle progression in both SH-SY5Y neuroblastoma cells and primary enteric neural crest cells (ENCCs), whereas BMI1 overexpression produced the opposite effects. BMI1 binds to the promoter region of the Wnt signaling pathway inhibitor Axin2 and suppressed its transcription by increasing H2AK119ub and reducing H3K4me3 at the Axin2 promoter, thereby hindering Wnt signaling. Moreover, overexpression of Axin2 decreased cell proliferation, migration and cell cycle progression. Treatment with HY-122816 (a Wnt signaling pathway agonist) reversed the inhibitory effects of PTC-209 on cell proliferation, migration, and cell cycle progression. Additionally, BMI1 upregulation promoted ganglion cell proliferation in Ednrb-/- mice. In conclusion: BMI1 facilitated Wnt signaling by mediating epigenetic silencing of Axin2, thereby promoting cell proliferation and migration in HSCR.

The remarkable conservation of DapE across diverse bacterial species makes it a promising target for combating drug resistance. In this study, 400 analogues were screened using virtual screening to evaluate their pharmacokinetic, toxicological, and bioactive properties. Fifty-two compounds meeting these criteria were selected for molecular docking analysis. Among these, five top-ranking compounds were identified based on docking scores, and two, ZINC262925003 (-7.1 kcal/mol) and ZINC237355153 (-7.0 kcal/mol), were selected due to their strong catalytic zinc-binding interactions at the active site. Extensive validation through 250 ns molecular dynamics simulation and Molecular Mechanics Poisson-Boltzmann Surface Area (MM/PBSA) analysis revealed high structural stability and robust binding interactions for these complexes. These findings highlight their potential as therapeutic agents against DapE, necessitating further validation through in vitro and in vivo studies.

Here, we perform a combined proteomic and phosphoproteomic profiling of HeLa cervical cancer cells after in vitro treatment with X-rays and carbon ions. We observed differential and extensive alterations at the proteins and phosphoproteins levels. In total, we observed 96 and 102 differentially expressed proteins (DEPs) after X-rays and C-ions irradiation, respectively. For phosphoproteins, our results revealed 21 and 41 DEPs in response to C-ions and X-rays ionizing radiation respectively. Furthermore, our study revealed several mechanisms significantly activated by cells in response to ionizing radiation, potentially related to cancer radioresistance, including sister chromatid segregation, rRNA processing, ribosomal large subunit biogenesis, positive regulation of phagocytosis, engulfment, peptidase regulatory activity and negative regulation of ERK1/2 cascade. We also identified three proteins IPM3, DUSP3 and COQ7, oppositely expressed across the C-ions and X-rays groups while MX2 phosphorylation was downregulated in both radiation qualities.
