Figure Lengend Snippet: Uptake of NPs by DTHP1 and HepG2 cells treated with 1 μg/ml LPS and 0.16 % (v/v) EtOH; (a) quantitative analysis of NP uptake at different concentrations, confirmed higher, dose-dependent uptake by DTHP1 cells.; n = 4 (b) fluorescence imaging of NP uptake also confirmed higher uptake in DTHP1 than in HepG2 cells: green-coumarin-6 loaded NPs, blue-nuclei (scale bar = 150 μm) (c) quantification of NP uptake after cells were pre-treated with free INT (0.1 μM and 1 μM); uptake of the PC-1+INT NPs reduced due to the free INT pretreatment, confirming Gpbar1 targeting capabilities of the NPs.

Figure Lengend Snippet: PPA-mediated reduction in lipid accumulation involves enhanced lipolysis and fatty acid oxidation in HepG2 cells. ( A ) Following 24 h incubation with 500 μM oleic acid (OA) or bovine serum albumin (BSA), HepG2 cells were exposed to PPA at concentrations of 0, 0.5, 0.75, 1, or 5 mM for an additional 48 h. Cell viability was determined via the CCK-8 assay. ( B ) Oil Red O staining images illustrate lipid droplets (scale bar = 200 μm). ( C ) Quantitative assessment of lipid content from Oil Red O staining. ( D ) Fluorescence images of BODIPY 493/503-stained lipid droplets (scale bar = 25 μm). ( E ) Mean fluorescence intensity quantification of BODIPY 493/503 staining. ( F , G ) Western blot analysis for detecting phosphorylated ATGL (p-ATGL) and total ATGL (t-ATGL). ( H , I ) CPT1A expression levels were examined by Western blotting. Colors represent the following groups: control (gray), OA alone (green), OA plus PPA at the indicated concentrations (orange). Group labels are displayed on the x-axis. Data represent mean ± SEM; n = 3. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001; ns represents no significant difference.

Figure Lengend Snippet: PPA promotes activation of CAMKII and ATGL in a Ca 2 ⁺-dependent manner in OA-overloaded HepG2 cells. ( A ) After a 24 h incubation with 500 μM OA or BSA, HepG2 cells were exposed to 0.5 or 1 mM PPA for 48 h. Cytosolic Ca 2+ levels were measured. ( B , C ) Western blot analysis for detecting phosphorylated CAMKII (p-CAMKII) and total CAMKII (t-CAMKII). ( D – F ) HepG2 cells pretreated with OA or BSA for 24 h were co-incubated with PPA (0.5 or 1 mM) in the presence or absence of 10 μM BAPTA. Protein extracts were then assessed for p-CAMKII, t-CAMKII, p-ATGL, and t-ATGL via Western blotting. Groups are denoted by color: control (gray), OA alone (green), OA + PPA (orange), and OA + PPA + BAPTA (lime green). PPA concentrations are as indicated. All groups are labeled on the x-axis. Data are expressed as mean ± SEM; n = 3. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001; ns represents no significant difference.

Figure Lengend Snippet: GPR43 is involved in PPA-induced activation of the Ca 2 ⁺–CAMKII–ATGL pathway in HepG2 cells. ( A ) After a 24 h incubation with 500 μM OA or BSA, HepG2 cells were exposed to 0.5 or 1 mM PPA with or without 1 μM GLPG0974, after which cytosolic Ca 2 ⁺ levels were measured. ( B – D ) Protein extracts were assessed for p-CAMKII, t-CAMKII, p-ATGL and t-ATGL via Western blotting. Groups are denoted by color: control (gray), OA alone (green), OA + PPA (orange), and OA + PPA + GLPG0974 (lime green). PPA concentrations are as indicated. All groups are labeled on the x-axis.
