In the present study, the expression levels of circ-PVT1, miR-124-3p and ZEB1 in PTX-resistant GC tissues and cells were detected by quantitative real-time polymerase chain reaction (RT-qPCR).
The present study aimed to investigate the association between the expression of ZEB1 and LAMA4 in gastric cancer and the possible underlying mechanisms of this.
To investigate the expression of long non-coding RNA zinc-finger E-box binding homeobox 1-AS1 (lncRNA ZEB1-AS1) in gastric cancer cells and tissues, to study its effect on the gastric cancer cell metastasis capacity, and analyze its clinical significance.
Our data revealed that downregulation of miR-200c primarily regulated cell morphology by downregulation of E-cadherin through upregulation of ZEB1, leading to poorly differentiated histology in gastric cancer.
In conclusion, the present study suggested that miR‑454 under expression may be involved in gastric cancer initiation and progression, by promoting proliferation, migration and invasion by directly targeting ZEB1. miR‑454/ZEB1‑based targeted therapy may be a potential strategy for the treatment of gastric cancer.
Furthermore, zinc‑finger E‑box‑binding homeobox factor‑1 (ZEB1) was identified as a putative target gene of miR‑205 in GC, which may be associated with its suppressive effects.
Treatment with TGF-β in GC cell lines resulted in morphological EMT changes, upregulation of lncRNA-ATB and ZEB1, and downregulation of miR-200c and CDH1.SB431542 reduced lncRNA-ATB expression.
The authors studied the effects of zinc finger E-box binding factor 1 (ZEB1) on latent-lytic switch of EBV infection in gastric cancer and explored the importance of EBV in gastric carcinogenesis.
A lower degree of differentiation of gastric cancer (p = 0.009), a higher TNM (tumor, node, and metastasis) stage (p = 0.010), and a larger scope of invasion were correlated with higher expression of ZEB1 (p = 0.041, 0.002).
