Article Title: IL-1β modulates inflammatory response of human bone marrow-derived MSCs and neutrophil recruitment in vitro via NF-kB-associated signaling

doi: 10.1186/s13287-026-05029-x

Figure Lengend Snippet: IL-1β stimulation increases expression of neutrophil recruitment and NF-kB signaling genes by BM-hMSCs. Heatmap clustering of the Z-score of the top 20 differentially expressed genes between unstimulated control BM-hMSCs (3 replicates, 1 donor, green) and IL-1 β stimulated BM-hMSCs (3 replicates, 1 donor, purple). Red color indicates higher expression of the genes and blue color indicates decreased expression A . Protein expression of CXCL1 (10 replicates, 4 donors), CCL2 (4 replicates, 2 donors), CXCL5 (4 replicates, 2 donors), and CXCL8/IL-8 (7 replicates, 3 donors) in BM-hMSCs secretome measured by ELLA or ELISA. Data are presented as median, and statistical analysis was performed using unpaired t-test with Welch’s correction B . Bar plot of the top 20 significant Gene Ontology (GO) biological processes representing IL- 1β induced upregulated differentially expressed genes C IL-1 β, Interleukin-1β; BM-hMSCs, Bone marrow derived human mesenchymal cells; CCL2, chemokine (C–C motif) ligand 2; CXCL1, chemokine (C-X-C motif) ligand 1; CXCL2, chemokine (C-X-C motif) ligand 1; CXCL8, chemokine (C-X-C motif) ligand 8; ****, p < 0,0001

Article Title: CXCR2 affects sensitization of radioresistant HPV-negative head and neck squamous cell carcinoma cells by ABT-263

doi: 10.1186/s13014-026-02798-w

Figure Lengend Snippet: ABT-263 decreases senescence and alters the SASP in UPCI:SCC040 and Cal33 cells. Cells were treated with 1 µM ABT-263 (Cal33) or 5 µM of ABT-263 (UPCI:SCC040) concomitantly with 6 Gy irradiation and analyzed on D4 or D6. ( A-B ) Gene expression of secreted factors measured by qRT-PCR and normalized to unirradiated DMSO controls. ( A ) UPCI:SCC040. ( B ) Cal33. ( C-D ) Secreted IL1A, IL1B, IL8 and CXCL1 protein levels were detected by ELISA on D4 and D6. Protein concentrations (pg/ml) were normalized to cell number. ( C ) UPCI:SCC040. ( D ) Cal33. ( E-F ) Relative CXCR2 gene expression shown as ΔCT values in ( E ) Cal33 and ( F ) UPCI:SCC040 cells. Values a represent means ± SEM of N = 2. Student’s t test: p < 0.05 (*), p < 0.01 (**), ns: not significant

Article Snippet: Cytokines IL-1α, IL-1β, IL-8 and CXCL1 were measured using DuoSet ELISA kits (R&D Systems, IL-1α Cat#DY200, IL-1β Cat#DY201-05, IL8 Cat#30021151, CXCL1 Cat#DY 275) according to manufacturer instructions.

Techniques: Irradiation, Gene Expression, Quantitative RT-PCR, Enzyme-linked Immunosorbent Assay
