JAK3 and TYK2 Serve as Prognostic Biomarkers and Are Associated with Immune Infiltration in Stomach Adenocarcinoma

الملخص EN

Background.

Stomach adenocarcinoma (STAD) is one of the most common malignant tumors.

The Janus kinases (JAKs) play a significant part in cellular biological process, inflammation, and immunity.

The roles of JAKs in STAD are still not systematically described.

Methods.

A series of bioinformatics tools were used to clarify the role of JAKs in STAD.

Results.

JAK3/TYK2 levels were significantly increased in STAD during subgroup analyses based on gender, tumor grade, cancer stages, and nodal metastasis status.

STAD patients with high levels of JAK3/TYK2 had poor overall survival, postprogression survival, and first progression.

Immune infiltration revealed a significant correlation between JAK3/TYK2 expression and the abundance of immune cells as well as immune biomarker expression in STAD.

JAK3/TYK2 was associated with the adaptive immune response, chemokine signaling pathway, and JAK-STAT signaling pathway.

Conclusions.

JAK3 and TYK2 serve as prognostic biomarkers and are associated with immune infiltration in STAD.
