Effects of dietary polyphenols on programmed cell death ligand 1 (PD-L1) expression in human breast and colon cancer cells. (A) Chemical structure of each of the polyphenols tested. (B) The Cal51 human breast cancer cell line and HCT116 colon cancer cell line, were cultured in vitro and treated with increasing concentrations of 5 polyphenols for 48 h, respectively, namely resveratrol (Res), piceatannol (Pic), <t>pterostilbene</t> (PTS), trimethylstilbene (TriMRes) and myricetin. Following treatment, the cells were harvested and stained for the surface expression of PD-L1 by flow cytometry. The geometric mean of mean fluorescent intensity (MFI) of phytoerythrin (PE) area was used as the readout of PD-L1. The levels of PD-L1 were converted to a bar graph to represent the respective changes in PD-L1 expression following treatment. The parental condition (also referred to as DMSO-treated, or control cells). Statistical difference reflects the comparison of treated samples to the parental condition. The data shown were from n=3 independent experiments. * P<0.05.

Effects of gnetol and <t>pterostilbene</t> on cardiomyocyte hypertrophy and viability. ( A ) The ability of ET1 (0.1 µM; 24 h) to induce myocyte enlargement was abolished by lower concentrations of gnetol (1–10 µg/mL), whereas higher concentrations of gnetol (50–100 µg/mL) reduced cell size in the presence and absence of ET1. n = 3; 40–45 myocytes/group. * p < 0.05 and ** p < 0.01 vs. control (open bars); † p < 0.05 and ‡ p < 0.01 vs. ET1. The effects of gnetol and pterostilbene on cardiomyocyte viability were therefore determined using triton x-100 as a positive control of reduced cardiomyocyte viability; ( B ) Lower concentrations of gnetol (1, 5, and 10 µg/mL) exhibited no adverse effects on calcein fluorescence (an indicator of viable cardiomyocytes), whereas higher concentrations (50 and 100 µg/mL significantly decreased viability. n = 3–4. * p < 0.05 vs. control (open bars); ( C ) only 1 µg/mL of pterostilbene exhibited no adverse effects on viability, whereas higher concentrations (5, 10 and 50 µg/mL) significantly decreased calcein fluorescence. n = 3–4. * p < 0.05 vs. control (open bars); ( D ) A sub-maximal concentration of gnetol (5 µg/mL) blocked ET1-induced protein synthesis (measured as l -azidohomoalanine [AHA] incorporation), a second marker of hypertrophy. n = 3; * p < 0.05 vs. control (open bars); † p < 0.05 vs. ET1.

PTE mitigates IR-induced lung injury in rats. (A) Representative images showing gross morphology, HE staining, MPO immunohistochemistry (IHC), and TUNEL staining of rat lungs following 1 h of left hilar clamping and 2 h of reperfusion. PTE was administered as a single intraperitoneal injection at the onset of reperfusion (30 mg/kg for the low-dose group, PTE-L; 60 mg/kg for the high-dose group, PTE-H). The Sham group underwent no hilar occlusion, whereas the IR group received an equivalent volume of saline. (B) Pulmonary edema after reperfusion was assessed by the lung W/D ratio. (C–E) Histopathological damage was quantitatively evaluated using lung injury score, the number of MPO-positive cells, and the number of TUNEL-positive cells. (F–I) Concentrations of TNF-α, IL-1β, IL-6, and IL-10 in lung tissue homogenates were measured by ELISA. (J–M) Relative mRNA expression levels of EGFR, MAPK8, PIK3CB and SRC were determined by qRT-PCR. HE staining: scale bar = 100 μm; MPO staining: scale bar = 50 μm; TUNEL staining: scale bar = 100 μm.
