Figure Lengend Snippet: A Human lung smooth muscle cells (HLSMCs), lung fibroblasts (HLFs), and small airway epithelial cells (HSAECs) were treated with TFP at the indicated concentrations for 24 h. Human peripheral blood eosinophils and neutrophils were treated with TFP for 2 h. Cell viability was assessed by staining the cells with Annexin V (AnnV) and DRAQ7. Viable cells, AnnV − DRAQ7 − ; apoptotic cells, AnnV + DRAQ7 − ; necrotic/late apoptotic cells, AnnV + DRAQ7 + . HSAECs, n = 6 from three independent experiments; HLSMCs, eosinophils, neutrophils, n = 4 from four independent experiments; HLFs, n = 3 from one individual experiment representative of three independent experiments (One-way ANOVA for HLSMCs, HLFs; Kruskal-Wallis for HSAECs; Friedman test for eosinophils, neutrophils). B – C Bone marrow-derived MCs (BMMCs) and peritoneal cell-derived MCs (PCMCs) treated under the same conditions as in ( A ) for 24 h. BMMCs, n = 5 from two independent experiments; PCMCs, n = 3 from one individual experiment representative of three independent experiments (One-way ANOVA). Untreated (control) cells were used for statistical comparisons to all other groups in all figures. The bar charts show mean values + SEM or median + interquartile range. * P < 0.05; ** P < 0 .01; **** P < 0.0001. D Effect of TFP on DNA degradation. MCs were preincubated with bafilomycin A1 (Baf A1) (20 nM) for 2 h followed by treatment with TFP (10 μΜ) for 2 h. DNA was extracted from MCs and fragmentation was assessed by agarose gel electrophoresis. St standard marker.

Article Snippet: Primary human lung fibroblasts (HLFs) (PCS-201-013) and primary human lung smooth muscle cells (HLSMCs)(PCS-130-010) were obtained from American Type Culture Collection (ATCC, Manassas, VA) and cultured following the manufacturer’s instructions.

Article Title: Acidic microenvironment-induced LAMC2 expression promotes proliferation, migration, and pathway regulation in non-small cell lung cancer cells

doi: 10.3389/fonc.2026.1747868

Figure Lengend Snippet: Acidic microenvironment condition screening and LAMC2 expression validation. (A) Comparison of relative LAMC2 expression levels in different cell lines (BEAS-2B, HCC827, and A549), showing a significantly higher expression in HCC827 and A549 cells compared to BEAS-2B cells. (B) Changes in LAMC2 expression in HCC827 and A549 cells under different lactate (LA) concentrations (10, 20, and 30 mM), showing significant increases in LAMC2 expression at 20 and 30 mM concentrations. (C) Changes in LAMC2 expression over time (0, 6, 12, and 24 h) in HCC827 and A549 cells treated with 20 mM LA, showing a significant increase in expression with longer treatment times. (D) Changes in LAMC2 expression under different acidic environment conditions (high LA, hydrochloric-acid-induced acidosis, and control groups) in HCC827 and A549 cells, with a significantly higher expression in the high LA and hydrochloric-acid-induced acidosis groups. ** p < 0.01, *** p < 0.001, **** p < 0.0001.

Article Snippet: Human normal lung epithelial BEAS-2B cells (ATCC ® CRL-9609TM) and lung cancer cell lines A549 (Procell, CL-0016, lung adenocarcinoma) and HCC827 (Procell, CL-0094, lung adenocarcinoma) were obtained from the indicated suppliers.
