Article Title: Epinephrine-mediated sensitization of thioredoxin 1 enhances chlorpromazine protection against acute hepatotoxicity

doi: 10.1186/s40360-026-01225-w

Figure Lengend Snippet: Epinephrine and/or chlorpromazine eliminate APAP-induced oxidative stress and inflammation and modulate the expression of the thioredoxin system in the liver. ( A ) and ( B ) demonstrate the hepatic levels of Nrf2 and TNF-α, respectively. ( C ), ( D ), and ( E ) show the effect of EP and CPZ on the thioredoxin system (Trx1/TrxR1) ( C ), thioredoxin-related proteins (TrxL1 and TrxIP) ( D ) mRNA and TrxR1 protein ( E ). Bars represent the mean (± SD) of 3 experiments. Means are compared by two-way ANOVA followed by Tukey’s tests. (*): p < 0.05, ** p < 0.01, *** p < 0.0001, **** p < 0.0001, and “ns” is not significant

Figure Lengend Snippet: Epinephrine and EGCG effect on cell viability, Nrf2, NTF, and TrxR1 expression in hepatoma cells. HepG2 and Huh7 cells were treated with epinephrine ( A ) or EGCG ( B ) for 24 h, after which cell metabolic activity was determined by MTT assay. Epinephrine enhanced cell viability in both HepG2 and Huh7 cells, whereas EGCG reduced cell viability. ( C ), ( D ), and ( E ) show the protein levels of Nrf2, TNF-α, and TrxR1, respectively, assessed in cells treated with EP, EGCG, CPZ, EP/CPZ, or EGCG/CPZ. Bars represent the mean (± SD) of 3 experiments. Groups were compared using ANOVA followed by Tukey’s tests.

Article Title: A Gravity‐driven Microfluidic Platform for High‐throughput Culture and Inflammatory Stimulation of Human Articular Chondrocytes

doi: 10.1002/cpz1.70489

Figure Lengend Snippet: Expected cellular responses of human articular chondrocytes under dynamic culture and IL‑1β‐induced inflammatory conditions. Representative results illustrate chondrocyte morphology, viability, extracellular matrix (ECM) expression, metabolic activity, and inflammatory responses under gravity‐driven flow conditions. (A) Representative z‐projection fluorescence images of chondrocytes cultured for 21 days in microchannels coated with a fibronectin–collagen type IV mixture. Cells form aggregates and microtissue‐like structures across regions I–III corresponding to increasing fluid shear stress levels. Cells are stained for F‐actin (red) and nuclei (DAPI, blue). (B) Representative Live/Dead fluorescence images showing time‐dependent viability and proliferation of chondrocytes cultured under dynamic conditions on days 3, 7, 14, and 21 (control), compared with IL‑1β‐stimulated cultures on day 21 (1 and 10 ng/ml, applied from day 15 to day 21). Control cultures show progressive formation of compact microtissue‐like aggregates (white arrows), whereas IL‑1β stimulation results in disrupted aggregates (yellow arrows). Green: calcein‐AM (live cells); red: ethidium homodimer‐1 (dead cells). (C) Representative z‐projection immunofluorescence images of ECM marker expression in region I after 21 days of culture, comparing control and IL‑1β‐stimulated samples. Images show merged fluorescence channels for collagen type II (green), aggrecan (red), and nuclei (DAPI, blue). (D–E) Quantification of corrected total cell fluorescence (CTCF) for collagen type II (D) and aggrecan (E) across regions I–III for control and IL‑1β‐stimulated cultures at day 21 (n = 44 cells per group). (F) Cell metabolic activity measured using a PrestoBlue assay for control and IL‑1β‐stimulated samples at day 21 ( n = 5 independent samples per group). (G–H) Quantification of inflammatory mediators in culture supernatant collected at day 21 using multiplex ELISA, including matrix metalloproteinases (MMP‐1, MMP‐2, MMP‐3, MMP‐7, MMP‐9, MMP‐13) and cytokines (IL‑1β, IL‑6, IL‑8) ( n = 3 independent samples per group).
