doi: 10.1038/s41598-025-96274-2

Figure Lengend Snippet: Protein expression profiles were analyzed through immunoblotting across experimental groups. Notably, GAPDH, Smad1/5, and p38 protein levels remained unaltered regardless of BMP2 expression status in SCC9 cells. BMP2 overexpression induced significant phosphorylation enhancement of Smad1/5 (52% increase, p = 0.017) and p38 (33% increase, p = 0.020). Conversely, BMP2 knockdown substantially attenuated Smad1/5 phosphorylation (76% reduction, p = 0.009) and p38 phosphorylation (34% reduction, p = 0.045), with asterisks denoting statistical significance. * p < 0.05, ** p < 0.01.

Figure Lengend Snippet: The mRNA expression levels of Smad1/4/5 and p38 in SCC9 cells were quantitatively analyzed using qPCR under different BMP2 modulation conditions. ( A ) Following BMP2 knockdown, significant upregulation of Smad1, Smad4, Smad5, and p38 mRNA expression was observed, with respective increases of 110%, 61%, 36%, and 38% compared to control groups ( p < 0.05 for all comparisons). ( B ) Conversely, BMP2 overexpression resulted in marked downregulation of these targets, showing respective reductions of 25%, 29%, 16%, and 22% in mRNA expression levels ( p < 0.05 for all measurements). All experimental data demonstrated statistically significant differences between treatment groups and corresponding controls. * p < 0.05, ** p < 0.01, *** p < 0.001.

Figure Lengend Snippet: ALK2/ALK3 type I receptors and BMPR2 type II receptor mediate BMP6-induced phosphorylation of SMAD1/5/8 in KGN cells. a KGN cells were pretreated for 1 h with DMSO, DM (10 µM), DMH-1 (0.25 µM), or SB431542 (10 µM), and cells were then treated with 100 ng/mL of BMP6 for another 6 h. The levels of phosphorylated SMAD1/5/8 protein levels were examined using Western blot analysis. b KGN cells were transfected with siCtrl, siALK2, siALK3, or siALK6 for 24 h, and cells were then treated with 100 ng/mL of BMP6 for another 1 h. The phosphorylated SMAD1/5/8 protein levels were examined using Western blot analysis. c KGN cells were transfected with siCtrl, siALK2, siALK3 or combined siALK2 and siALK3 for 24 h, and cells were then treated with 100 ng/mL of BMP6 for another 1 h. The phosphorylated SMAD1/5/8 protein levels were examined using Western blot analysis. d–f KGN cells were transfected with siCtrl, siBMPR2 ( d ), siACVR2A ( e ), or siACVR2B ( f ) for 48 h, and cells were then treated with 100 ng/mL of BMP6 for another 6 h. The phosphorylated SMAD1/5/8 protein levels were examined using Western blot analysis. g–h KGN cells were transfected with siCtrl, combined siBMPR2 and siACVR2A, combined siBMPR2 and siACVR2B, or combined siACVR2A and siACVR2B for 48 h, and cells were then treated with 100 ng/mL BMP6 for another 6 h.
