NF2 is a candidate diagnosis, prognostic, and immunotherapeutic biomarker: a systematic pan-cancer analysis.


ABSTRACT:

Background

Neurofibromin 2 (NF2) regulates diverse cellular events such as transcription, translation, ubiquitination, and micro-RNA biosynthesis. Previous evidence revealed that aberrant expression of NF2 contributes to tumorigenesis in mesothelioma, meningioma, and breast cancer. However, there is no comprehensive pan-cancer analysis to explore NF2's function in cancer diagnosis, prognosis, and immunological prediction.

Methods

By extensive use of data profiles from The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx) project, Cancer Cell Line Encyclopedia (CCLE), CIBERSORT, Human Protein Atlas (HPA), and cBioPortal, we employed various bioinformatics methods to explore the role of NF2 in pan-cancer, including analyzing the association between NF2 and tumor diagnosis, prognosis, immune cell infiltration, tumor mutational burden (TMB), and microsatellite instability (MSI). Moreover, the co-expression relationship between NF2 expression with RNA modification genes was also constructed.

Results

Our research indicated that NF2 was highly expressed in most kinds of tumors. NF2 showed an early diagnosis value in 13 types of tumors and was significantly associated with the prognosis in most tumors. The results also verified that NF2 expression was associated with most immune-related cells and signaling pathways in pan-cancer, especially in diffuse large B-cell lymphoma and ovarian serous cystadenocarcinoma. Furthermore, NF2 gene expression was associated with TMB and MSI in many tumors.

Conclusions

Our study reveals that NF2 might be helpful in tumor early diagnosis and prognosis evaluation. The expression of NF2 is highly associated with the tumor immune microenvironment. Additionally, NF2 is a potential biomarker for predicting the efficacy of immune checkpoint inhibitors therapy. Therefore, NF2 can be a promising diagnostic, prognostic, and immunotherapeutic biomarker for many types of tumors.
