LTBP2 and gastric cancer: In our study, re-expression of the NF-κB2 gene in HGC-27 and HGC-27/DDPR cells, in which LTBP2 had already been silenced, effectively reversed the increased effect of silencing LTBP2 on cisplatin sensitivity in GC cells and significantly upregulated the protein expression levels of p52, Bcl-3, and cyclin D1.
