Cyclophilin A knockdown inhibits the proliferation and metastatic ability of AGS gastric cancer stem cells by downregulating CD147/STAT3/AKT/ERK and epithelial‑mesenchymal transition.

ABSTRACT: Gastric cancer stem cells (GCSCs) contribute to the challenging aspects of gastric cancer, such as progression, metastasis, treatment resistance and recurrence. Inhibitors targeting cyclophilin A (CypA) have shown potential in curtailing GCSC growth. Building upon this, the current study delved deeper into understanding the functional role of CypA in controlling the proliferation and metastatic capabilities of GCSCs, employing CypA‑specific small interfering RNA. The results revealed that knockdown of CypA led to significant suppression of the growth and tumorsphere‑forming capacity of GCSCs derived from AGS cells. This effect was mediated by arresting the cell cycle at the G₀/G₁ and S phases, and promoting apoptosis. Furthermore, silencing of CypA exerted inhibitory
