Article Title: C-terminal interleukin 1 alpha (IL-1α) overexpression drives EMT and a vulnerability to ferroptosis in HNSCC

doi: 10.1016/j.redox.2026.104172

Figure Lengend Snippet: Characterization of IL-1α overexpression constructs in Cal27 HNSCC cells. Gene expression (A-C), protein release (D) and protein expression (E-G) of the three IL1A constructs – Full- Length (FL), N-terminal (NT) and C-terminal (CT) in the Cal27 IL-1α-overexpressing cells were analyzed by RT-qPCR, ELISA and Western blot respectively compared to control. GAPDH was used as an endogenous control for PCR analysis (A-C); α-Tubulin was used as the loading control for whole cell lysate and cytoplasmic fraction western blots (E-F); and Lamin B1 was used as the loading control for the nuclear fraction Western blot (G). Bars represent mean ± SEM from n = 3 independent experiments. IL-1α band intensities were normalized to the respective loading controls. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ∗∗∗∗p < 0.0001.

Figure Lengend Snippet: IL-1α overexpression alters expression of IL-1 pathway genes. Gene expression of IL1B (A), IL6 (B), IL8 (C), IL1RN (D), IL1RAP (E) and IL1R1 (F) in the three IL1A constructs – Full-Length (FL), N-terminal (NT) and C-terminal (CT) in Cal27 IL-1αoverexpressing cells were analyzed by RT-PCR using GAPDH as an endogenous control. Protein secretion of IL-1β (G), IL-6 (H), IL-8 (I), and IL1RA (J) in cell culture supernatants was quantified by ELISA with protein concentrations normalized to cell numbers. Whole cell lysates were analyzed for IL-1R1 expression by Western blot using GAPDH as a loading control (K). Bars represent mean ± SEM from n = 3 independent experiments.∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ∗∗∗∗p < 0.0001.

Article Title: Multifaceted intestinal defense following experimental blunt abdominal trauma

doi: 10.1007/s00068-026-03145-0

Figure Lengend Snippet: Posttraumatic defensive pathway activation and cellular immune response in the murine jejunum. ( A ) Proteome profiler-based pathway analysis revealed activation of immune and defense-related mechanisms. The 15 pathways with the highest degree of regulation are shown. ( B, C ) Histological quantification in jejunal tissue demonstrated a significant increase of CD3 + T lymphocytes in the trauma group relative to controls. ( D ) Gene expression profiling of S100a8 showed a significant post-traumatic upregulation in traumatized mice compared to sham animals. ( E ) In contrast, no statistically significant alteration was observed in interleukin-6 (Il6) expression. ( F ) Plasma levels of C5a were unaltered by traumatic exposure. ( G ) C5a in bronchoalveolar lavage fluid (BALF) was significantly increased in mice 24 h after AT compared to shams. C : n = 180 per group; D-G : n = 4–5 per group. Statistical analysis was performed using the Mann-Whitney U test, with significance defined as p < 0.05. Data are presented as mean ± standard error of the mean (SEM)

Article Snippet: To measure the concentrations of C5a in plasma and BALF, a sandwich ELISA was performed using the C5a ELISA Kit Mouse Duo Set (R&D Systems, Minneapolis, USA).
