ACE2 maybe serve as a prognostic biomarker in breast invasive carcinoma.

ABSTRACT:

Background

Breast cancer is a frequently occurring malignant tumor in women. Angiotensin-converting enzyme 2 (ACE2) is widely expressed in most organs; however, the association of ACE2 with prognosis and immune infiltration in breast invasive carcinoma (BRCA) remains elusive.

Methods

We explored the expression level and prognostic value of ACE2 in patients with BRCA using a series of online bioinformatics analysis databases encompassing Oncomine, UALCAN, Kaplan-Meier plotter, TIMER, LinkedOmics, and GEO. qRT-PCR was performed to verify our findings.

Results

Angiotensin-converting enzyme 2 mRNA and protein expression levels were decreased in BRCA tissues, and patients with low ACE2 expression levels had a poor prognosis. DNA promoter methylation of ACE2 significantly d
