Article Title: Influence of diet-induced obesity and voluntary exercise training on cardiac lipids and mitochondrial function in mice

doi: 10.1016/j.jshs.2025.101095

Figure Lengend Snippet: Voluntary exercise alters left ventricle gene and protein expression related to mitochondrial biogenesis and dynamics in high fat- and chow-fed mice. (A) Western blot analysis to assess purity of crude mitochondria isolation where left ventricle mitochondrial pellet expresses mitochondrial marker TOM70 and COXIV and supernatant expresses calnexin. Protein expression of (B) LCLAT1 and (C) MFN2 in left ventricle-isolated crude mitochondria and (D) LCLAT1, (E) PGC-1α, and (F) MFN2 in left ventricle tissue from male VET or sedentary mice fed an HFD or chow diet. Left ventricle mRNA expression of (G) OPA1 and (H) DRP1 in male VET or sedentary mice fed an HFD or chow diet. Values were calculated relative to 18S housekeeper. Calnexin and β-actin were used as internal controls of protein loading in left ventricle samples and COXIV as internal control of protein loading in crude mitochondria samples. Analysis was performed using two-way analysis of variance with Tukey’s post hoc test for multiple comparisons. Data are expressed as mean ± standard error of the mean. (B–C) n : 5–6 per group. (D–F) n = 7 per group. (G and H) n = 9 per group. CE = chow exercise; CS = chow sedentary; COXIV = cytochrome c oxidase subunit 4; DRP1 = dynamin-related protein 1; HE = high fat diet exercise; HFD = high fat diet; HS = high fat diet sedentary; LCLAT1 = lysocardiolipin acyltransferase 1; MFN2 = mitofusin-2; OPA1 = optic atrophy 1; PGC-1α = peroxisome proliferator-activated receptor gamma coactivator-1α; TOM70 = translocase of outer mitochondria membrane 70; VET = voluntary exercise training.

Article Title: Biomimetic photodynamic nanoparticles exert anti-tumor therapy by inducing ferroptosis in non-small cell lung cancer

doi: 10.1016/j.mtbio.2026.103327

Figure Lengend Snippet: Schematic diagram of the preparation and anticancer mechanism of M1@CAT-Ce6-Rh2 Lips. (A) Schematic illustration of the preparation procedure for M1 macrophage membrane-camouflaged self-oxygenating nanoparticles (M1@CAT-Ce6-Rh2 Lips). Briefly, Nanoparticles were prepared using the anticancer drug Rh2 as the membrane material to encapsulate the photosensitizer Ce6 and CAT, which were then coated with lipopolysaccharide (LPS)-stimulated M1 macrophage membrane to enhance uptake by tumor cells. (B) Schematic depiction of the in vivo fate and mechanism of antineoplastic activity of M1@CAT-Ce6-Rh2 Lips upon intravenous administration. These biomimetic nanoparticles possess prolonged systemic circulation duration and preferential enrichment within tumor regions through the enhanced permeability and retention (EPR) effect. Following internalization into cancer cells, each functional component exerts its unique biological activity, synergistically triggering ferroptosis in cancer cells and ultimately exerting potent antitumor efficacy.
