This study intends to investigate how Inhibin subunit beta A (INHBA) promotes the progression of GC by activating the mitogen-activated protein kinase (MAPK) signaling pathway via targeting Integrin alpha-6 (ITGA6).<h4>Methods</h4>Quantitative reverse transcription-Polymerase Chain Reaction (qRT-PCR) and Immunohistochemistry (IHC) were utilised to validate the expression levels of INHBA in GC, which were subsequently correlated with the clinicopathological factors and outcomes. Here, ITGA6 is linked to gastric cancer.
