As an important member of the kindlin family, fermitin family member 1 (FERMT1) can interact with integrin and its aberrant expression involves multiple tumors. However, there are few systematic studies on FERMT1 in pancreatic carcinoma (PAAD). We used several public databases to analyze the expression level and clinicopathological characteristics of FERMT1 in PAAD. Meanwhile, the correlation between FERMT1 expression and diagnostic and prognostic value, methylation, potential biological function, immune infiltration, and sensitivity to chemotherapy drugs in PAAD patients were investigated. FERMT1 was significantly up-regulated in PAAD and correlated with T stage, and histologic grade. High FERMT1 expression was closely connected with poor prognosis and can be used to diagnose PAAD. Moreover, the methylation of six CpG sites of FERMT1 was linked to prognosis, and FERMT1 expression was significantly related to N6-methyladenosine (m(6)A) modification. Functional enrichment analysis revealed that FERMT1 co-expression genes participated in diverse biological functions including necroptosis. In addition, the expression of FERMT1 was associated with immune cell infiltration and the expression of immune checkpoint molecules. Finally, FERMT1 overexpression may be sensitive to chemotherapy drugs such as Palbociclib, AM-5992 and TAE-226. FERMT1 can serve as a diagnostic and prognostic marker of PAAD, which is connected with immune cell infiltration and the modulation of m(6)A and necroptosis. |
