Figure Lengend Snippet: Schematic of the anti-atherosclerotic mechanism of OPN-HMCN@MLT. ( A ) The study commenced with the synthesis of mesoporous carbon nanospheres (MCN) functionalized with an OPN-binding peptide and hyaluronic acid to construct the OPN-HMCN nanoplatform. The OPN-binding peptide was designed to recognize OPN enriched in the extracellular matrix and on the surface of foam cells, thereby enabling selective accumulation in OPN-rich pathological regions. Following OPN recognition, OPN-HMCN@MLT undergoes CD44-dependent endocytosis. Melatonin (MLT), a lipid autophagy–promoting agent, was subsequently encapsulated within the nanocarrier to form OPN-HMCN@MLT. Firstly, the released MLT can bind to and upregulate the expression of PPARα and PPARγ, which then promote the expression of downstream genes (ABCA1, ABCG1, ACOX-1, and CTP1A) and trigger the lipophagy. ( B ) Subsequently, its lipophagy-enhancing effects, including ABCA1/G1-mediated cholesterol efflux and CTP1A/ACOX-1-mediated mitochondrial fatty acid oxidation, were studied to confirm the reversal of foam cell formation. ( C ) These effects eventually promote foam cells to reverse into macrophages.

The data is displayed as mean ± SEM from four independent biological experiments (n = 4). One-way ANOVA followed by Tukey ' s post hoc test was used to determine statistical significance. *p < 0.05 indicates significance compared to the control group, while #p < 0.05 denotes significance compared to the OA group. Groups: Control (0.1% DMSO); OA (0.4 mM), oleic acid-induced HepG2 cells without treatment; SR 10, OA-induced HepG2 cells +10 μg/mL Sangyod rice extract; SR 50, OA-induced HepG2 cells +50 μg/mL Sangyod rice extract; SR 100, OA-induced HepG2 cells +100 μg/mL Sangyod rice extract.

Figure Lengend Snippet: (a) Cell proliferation of SaOS-2 cells onto the different CaP discs for 4 h, 7, 14 and 21 days. (b) ALP activity of SaOS-2 cells cultured onto the CaP substrates for 4 h, 7, 14 and 21 days. The same letter indicates no statistically significant differences for the same group at different time points while the same number denotes no statistically significant differences for each time point among all samples. (p < 0.05).

Figure Lengend Snippet: Merged CLSM images of SaOS-2 cells cultured for 4 h and 7 days on the nanostructured CaP substrates, as well as the Flat and Ti controls. Actin filaments were stained with Alexa Fluor™ 546 phalloidin (orange fluorescence signal) and nuclei with DAPI (blue fluorescence signal).

Figure Lengend Snippet: (a) mRNA expression of osteogenic genes ALPL, RUNX2 and SPP1 of SaOS-2 cells cultured directly onto the CaP substrates for 1, 3, 7 and 14 days, determined by real-time PCR (n = 3). (b) Interaction of RAW 246.7 cells with treated discs up to 7 days in cell culture. i) mRNA expression of pro-inflammatory genes TNF, IL1B and IL6 of cells in the direct cell culture, determined by real-time PCR for 1, 3 and 7 days (n = 3). All values are relativized to values of cells at day 1. ii) Protein expression level after 7 days of direct cell culture on the treated discs, measured by inflammation antibody array. Values of protein signal are quantified by image analysis and relativized to control. In Fig. a) and bi), the same letter indicates no statistically significant differences for the same group at different time points while the same number denotes no statistically significant differences for each time point among all samples. (p < 0.05).
