Figure Lengend Snippet: The inhibition of L. crispatus -derived D-LA on FOXD1 expression and growth of Ect1/E6E7 cells. 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)
