Опубликована: Май 5, 2024

Abstract Self‐assembling peptides have numerous applications in medicine, food chemistry, and nanotechnology. However, their discovery has traditionally been serendipitous rather than driven by rational design. Here, HydrogelFinder, a foundation model is developed for the design of self‐assembling from scratch. This explores self‐assembly properties molecular structure, leveraging 1,377 non‐peptidal small molecules to navigate chemical space improve structural diversity. Utilizing 111 peptide candidates are generated synthesized 17 peptides, subsequently experimentally validating biophysical characteristics nine ranging 1–10 amino acids—all achieved within 19‐day workflow. Notably, two de novo‐designed demonstrated low cytotoxicity biocompatibility, as confirmed live/dead assays. work highlights capacity HydrogelFinder diversify through molecules, offering powerful toolkit paradigm future endeavors.

Abstract Aromatic residues in assembling peptides play a crucial role driving peptide self‐assembly through π–π stacking and hydrophobic interactions. Although various aromatic capping groups have been extensively studied, systematic investigations into the effects of single amino acids remain limited. In this study, influence aromatic‐aromatic interactions on disulfide‐rich is systematically investigated by incorporating three different acids. Their folding propensity, self‐assembling properties, rheological behaviors are evaluated. These results indicate that significant effect abilities, as determined critical aggregation concentration (CAC) measurements. Furthermore, biocompatibility these hydrogels assessed, their potential for 3D cell culture explored. The injectable F1‐ox hydrogel demonstrate excellent SHED NIH3T3 cells exhibit porous structure facilitates nutrient cellular metabolic waste exchange.

Abstract The prediction of gelation is an important target, yet current models do not predict any post‐gel properties. Gels can be formed through the self‐assembly many molecules, but close analogs often form gels. There has been success using a number computational approaches to understand and from molecular structures. However, these focus on whether or gel will form, properties resulting Critically, it gels that are for specific application, simply formed. Supramolecular kinetically trapped, meaning predicting inherently difficult challenge. Here, first successful priori such self‐assembled, supramolecular systems reported.

DGCLCMI: a deep graph collaboration learning method to predict circRNA-miRNA interactions

BMC Biology, Год журнала: 2025, Номер 23(1)

Опубликована: Апрель 23, 2025

Abstract Background Numerous studies have shown that circRNA can act as a miRNA sponge, competitively binding to miRNAs, thereby regulating gene expression and disease progression. Due the high cost time-consuming nature of traditional wet lab experiments, analyzing circRNA-miRNA associations is often inefficient labor-intensive. Although some computational models been developed identify these associations, they fail capture deep collaborative features between interactions do not guide training feature extraction networks based on high-order relationships, leading poor prediction performance. Results To address issues, we innovatively propose novel graph collaboration learning method for interaction, called DGCLCMI. First, it uses word2vec encode sequences into word embeddings. Next, present joint model combines an improved neural filtering with network optimization. Deep interaction information embedded informative within sequence representations prediction. Comprehensive experiments three well-established datasets across seven metrics demonstrate our algorithm significantly outperforms previous models, achieving average AUC 0.960. In addition, case study reveals 18 out 20 predicted unknown CMI data points are accurate. Conclusions The DGCLCMI improves representation by capturing information, superior performance compared prior methods. It facilitates discovery sheds light their roles in physiological processes.
