Figure Lengend Snippet: The impact of DRG neuron axonal promotion via SKP-SCs. (a) Schematic illustration of DRG neurons culture in vitro. The cultured DRG neurons for 20 h and 40 h (b) showed increased neurite outgrowth. Scale bar: 50 μm. (c) The β-Tubulin III cell immunofluorescent staining (red) showed neurites are undergoing a process of growth in length from 48 h to 96 h. Scale bar: 50 μm. Schematic illustration showed the direct (d) and in-direct (Transwell®) (e) co-culture of DRG neurons and SKP-SCs. (h) After direct co-culture 48 h, GFP-SKP-SCs promoted DRGs neurite outgrowth significantly compared to control group (i). (k) After in-direct co-culture 72 h, GFP-SKP-SCs promoted DRGs neurite outgrowth (j) significantly compared to control group (g). Scale bar: 50 μm for f, g, i, j. (l) Morphological changes under phase contrast microscopy in DRG neurons and SKP-SCs direct co-culture, DRG neurons in separate culture, and in-direct (Transwell®) co-culture of DRG neurons and SKP-SCs after 24 h, 48 h, and 72 h. Scale bar: 100 μm. (m) Schematic illustration of LC-MS/MS analysis to identify the secreted proteins from SKP-SCs cultured in serum free basic medium for 4 h. After concentration, the cleared conditioned medium was collected for LC-MS/MS analysis, database search, and protein identification. The enrichment analysis showed top 20 diseases and functions (n) and canonical pathways (o) according to the IPA database. The PPI network shows the interaction of the proteins involved in the functions highly correlated with regeneration (p). Among them, functions as formation of lamellipodia, extension of neurites, extension of cellular protrusions, and related proteins were highlighted (q). Functions as migration of endothelial cells, development of endothelial tissue, vasculogenesis, development of epithelial tissue, endothelial cell development, and related proteins were highlighted (r). Orange nodes stand for a predicted activation state. Blue nodes stand for a predicted inhibition state.

Article Title: Harnessing Lactiplantibacillus plantarum EP21 and its membrane vesicles to inhibit myopia development

doi: 10.1080/19490976.2025.2534677

Figure Lengend Snippet: Lactiplantibacillus plantarum EP21 membrane vesicles containing miRNAs modify inflammation and ubiquitination pathways. (a) Ingenuity pathway analysis identified the gene networks associated with inflammation and ubiquitination pathways. (b) The levels of genes associated with ubiquitination, specifically TNF alpha induced protein 3 (TNFAIP3), TNFAIP3-interacting protein 1 (TINP1), and Tax1 binding protein 1 (TAX1BP1), were significantly elevated in RPE-1 cells following treatment with EP21 MV. NC refers to the negative control condition. (c) Total protein was extracted from the retina of eyes subjected to negative control, transforming growth factor β2 (TGF-β2), and EP21 MVs treatment, and the extent of protein ubiquitination was assessed using western blot analysis. (d) RPE-1 cells underwent treatment with tumor necrosis factor (TNF) α, transfection with miRNAs or co-treatment with TNFα and miRNAs for a duration of 24 hours. The level of protein ubiquitination was evaluated through western blotting. Poly-ub: polyubiquitinated protein; free-ub: free ubiquitin. Relative free ubiquitin expression levels were determined using image J software. Relative expression levels (below the lanes) were normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
