Fig. 2: HP infection elevates ONECUT2 expression.

A Time-dependent expression of ONECUT2, CagA, NFκB (p65), and p-NFκB (s536) proteins in AGS and NCI-N87 GC cells upon infection with carcinogenic HP (ATCC 43054) was assessed by western blotting. B ONECUT2 mRNA expression levels in HP-infected AGS and NCI-N87 GC cells was quantified by RT-qPCR (n = 3). C The mRNA and protein expression of ONECUT2 were measured in gastric tissue with the infection of mouse pathogenic HP (PMSS1). D Spatial transcriptome analysis of the Po1 section (HP-infected GC tissue) revealed ONECUT2 and RELA mRNA expression in 10 distinct clusters. Of these, clusters 0, 1, 2, 3, 4, and 9 showed increased ONECUT2 expression, correlating with an increase in RELA. E Spatial transcriptome analysis of the Ne1 section (non-HP-infected GC tissue) revealed ONECUT2 and RELA mRNA expression in 14 distinct clusters. Of these, cluster 1 showed increased ONECUT2 expression, which was associated with elevated RELA levels. F, G Spatial transcriptome analysis revealed that mRNA expression levels of ONECUT2 (F) and RELA (G) were higher in HP-infected GC tissue than in non-HP-infected GC tissue. ns, not significant; **P < 0.01; ***P < 0.001; ****P < 0.0001.
