Next, we predicted ANXA2-associated proteins and constructed a protein-protein interaction network via the STRING database. Furthermore, we obtained the biological processes associated with ANXA2 in HCC through GO, KEGG and GSEA enrichment analysis. Finally, CCK8, wound healing, and transwell were used to verify these biological processes in HCCLM3 cell lines. Insight box ANXA2 is highly expressed in a variety of tumors, with significantly higher levels in HCC than in normal tissues. ANXA2 expression is positively correlated with T stage, histologic grade, residual tumor, pathologic stage, tumor status and fibrosis ishak score in HCC, and high ANXA2 expression suggests a poorer prognosis. Additionally, ANXA2 has diagnostic value in HCC. Its expression is closely associated with S100A family proteins and immune infiltration. Enrichment analysis showed that high ANXA2 expression activates biological processes such as epithelial-mesenchymal transition (EMT), NF-κB and Wnt signaling pathways.

La Ribonucleoprotein 4B (LARP4B) is known to function as a pro-oncogenic factor in digestive tumors, but its specific role and potential mechanisms remain unclear in pancreatic cancer (PC). In this study, we found that LARP4B was upregulated in PC tissues and cells. Overexpression of LARP4B promoted PC cell proliferation and invasion, while knockdown of LARP4B inhibited PC cell proliferation and invasion. Furthermore, knockdown of LARP4B was associated with intracellular iron overload, increased levels of reactive oxygen species (ROS) and malondialdehyde (MDA), and decreased glutathione (GSH) content and superoxide dismutase (SOD) activity in PC cells. Mechanistically, LARP4B binds to mRNA of with-no-lysine kinase 1 (WNK1) and promotes its stability, and WNK1 competitively binds to the partial Kelch domain of Kelch-like ECH-associated protein 1 (Keap1) to promote the nuclear translocation of nuclear factor erythroid-2-related factor 2 (NRF2), thereby activating the NRF2/GCH1/BH4 pathway and inhibiting ferroptosis in PC cells. ML385, a NRF2 nuclear translocation inhibitor, partially rescued the inhibitory effect of WNK1 on ferroptosis in PC cells. Finally, in vivo experiments showed that knockdown of LARP4B suppressed tumor growth in PC xenograft mice. In conclusion, our study demonstrated that LARP4B inhibited ferroptosis by activating the WNK1-mediated NRF2/GCH1/BH4 pathway, thereby promoting PC progression.

Sequence information from the resulting set of bio-panned heptapeptides was analyzed and mined to determine likely sites of interaction between two subunits of RV-PLA2 homo dimers and between RV-PLA2 and the γPLA2 inhibitor PIP from Malayopython reticulatus. This was accomplished in part by sequence alignment of the affinity-selected peptides with the sequences of RV-PLA2 and PIP. Because similarity scores calculated from sequence alignments proved inadequate to determine interaction interfaces accurately for RV-PLA2 dimers, we explored the use of amino acid frequency-based interactions scores (SFI/SFIN) for a more accurate prediction of protein-protein interaction sites. Heptamers with elevated SFI(N) scores were compared to interfaces of interaction observed in crystal structures of RV-PLA2 homodimers and to sites of interaction predicted by protein-protein docking between structures of RV-PLA2 and model of PIP. Segments with a high density of protein-protein contacts coincided with heptamer sequences exhibiting SFI and/or SFIN scores significantly above average, in both RV-PLA2 homodimers and in RV-PLA2 γPLI heteromeric structures. Elevated SFI and SFIN scores were associated with peptide function since the heptamers with some of the highest SFI and SFI(N) scores, LPGLPLS, GLPLSLQ and SLQNGLY constitute the known PLA2 inhibitor P-PB.I (LPGLPLSLQNGLY) while KLGRVDI, and WDGVYIR, constitute PIP-17 (LGRVDIHVWDGVYIRGR), IC50 for hsPLA2: 5.3 μM. A graph showing the alignment of maxima between SFI scores and average solvent accessibility (per heptamer) suggests that solvent accessibility is a major driver of both protein-protein interaction and phage selection. Insights We show by computational methods that in sets of small phage-displayed peptides of the same length selected for binding to the same target protein, amino acids contributing to binding at a particular position occur at higher frequencies than in random peptides. This position-specific selection of particular amino acids can be detected in the position-specific amino acid frequency distribution of that set of selected peptides. Therefore, when this position-specific amino acid frequency is mapped back onto a particular amino acid sequence of the same length, the sum of these frequencies can function as a measure of enrichment of selected amino acids.</p>","PeriodicalId":520649,"journal":{"name":"Integrative biology : quantitative biosciences from nano to macro","volume":"17 ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144577585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the precise cause of preeclampsia is not well defined. Ferroptosis is a type of cell death involving abnormal accumulation of iron and lipid reactive oxygen species (ROS) in cells. Accumulating evidence indicates that ferroptosis may contribute to preeclampsia development, but the underlying mechanism remains unclear. Several ubiquitin-specific proteases (USPs) have been reported to repress ferroptosis, but whether other USPs regulate ferroptosis and preeclampsia development remains elusive. Here we identified USP46 as a potent regulator of erastin-induced ferroptosis in BeWo trophoblasts, which serve as an in vitro model to study preeclampsia. We found that overexpression of USP46 promoted erastin-induced ferroptosis in BeWo cells, while knockdown of USP46 led to resistance to erastin-induced ferroptosis. This resistance could be reversed by excessive cold-inducible RNA-binding protein (CIRBP). Immunoprecipitation experiments showed that USP46 interacts with CIRBP to inhibit its ubiquitination. These findings suggest that USP46 sensitizes BeWo cells to ferroptosis by stabilizing CIRBP. Insight Box Preeclampsia is a severe pregnancy complication with an unknown pathogenesis.

Several serum-free formulations have been developed in the past, however they are often cell type specific, contain animal-derived components, and lack long-term culture validation. In this study, we developed a novel animal component-free (ACF) media and investigated its effectiveness on four commonly used mammalian cell lines via long-term (up to 90 days) morphological, transcriptomic, and proliferative analyses. Cells cultured in our ACF medium exhibited comparable cellular morphologies and equal or greater growth rates compared with cells cultured with FBS. Additionally, differentially expressed genes between the FBS-grown and ACF-grown groups were predominantly associated with functions linked to proliferation and cell attachment. While the tested cells were initially derived using conventional methods and include non-human lines, this study demonstrates that our medium supports long-term culture without animal-derived supplements. The findings from this study indicate that this medium is a suitable replacement to FBS-containing medium for several common cell lines.

Due to the prevalence of noise and degeneracy in evolved systems, in many cases the workings of everything from gene regulatory networks to protein-protein interactome networks remain black boxes. One consequence of this black-box nature is that it is unclear at which scale to analyze biological systems to best understand their function. We analyzed the protein interactomes of over 1800 species, containing in total 8 782 166 protein-protein interactions, at different scales. We show the emergence of higher order 'macroscales' in these interactomes and that these biological macroscales are associated with lower noise and degeneracy and therefore lower uncertainty. Moreover, the nodes in the interactomes that make up the macroscale are more resilient compared with nodes that do not participate in the macroscale. These effects are more pronounced in interactomes of eukaryota, as compared with prokaryota; these results hold even after sensitivity tests where we recalculate the emergent macroscales under network simulations where we add different edge weights to the interactomes. This points to plausible evolutionary adaptation for macroscales: biological networks evolve informative macroscales to gain benefits of both being uncertain at lower scales to boost their resilience, and also being 'certain' at higher scales to increase their effectiveness at information transmission.
