A . immunofluorescence staining for HPV16 E7 protein in Ect1/E6E7 cells after 24-hour treatment with L. crispatus or L. gasseri culture supernatants, or D-LA. Nuclei are counterstained with DAPI (blue). Scale bar = 50 μm. B . HPV16 fluorescence intensity after treatments (mean±SD, n = 3; ** p < 0.01). C . CCK-8 assay measuring cell vitality after treatments (mean±SD, n = 3; ** p < 0.01). D . qPCR analysis of FOXD1 mRNA levels relative to GAPDH (mean±SD, n = 3; * p < 0.05, ** p < 0.01). Four co-culture system: without additives (control), with L. crispatus culture supernatant ( L. crispatus group), with L. gasseri culture supernatant ( L. gasseri group), or with purified D-LA (D-LA group)

Article Title: Single-cell and multi-omics analyses identify CAMP-associated neutrophil remodeling during radiochemotherapy in cervical cancer

doi: 10.3389/fcell.2026.1773562

Figure Lengend Snippet: In vitro validation of key genes and associated ligand signaling involved in the response to chemoradiotherapy in cervical cancer. (A) mRNA expression of CAMP in normal cervical squamous epithelial cells from the external cervical os (Ect1/E6E7) and the cervical cancer cell line HeLa following chemoradiotherapy (RCT) treatment. RCT was simulated by X-ray irradiation at graded doses (Gy) for 30 min, followed by cisplatin (DDP) treatment for 24 h. (B–I) mRNA expression levels of differentially regulated ligand signals in HeLa cells from the Blank, CAMP overexpression (CAMP-OE), CAMP knockdown (CAMP-KD), RCT, RCT + CAMP-OE, and RCT + CAMP-KD groups. (J,K) mRNA expression levels of key ligand–receptor pairs in neutrophils and HeLa cells after co-culture before and after RCT treatment. Expression of the ligands COL1A1 (J) , COL1A2 (K) , and ANXA1 (L) was measured in HeLa cells, whereas expression of the receptors CD44 (M) , FPR1 (N) , and FPR2 (O) was assessed in neutrophils.

Article Snippet: HeLa and Ect1 cell lines were obtained from ATCC.
