Background

Beta blockers act on the beta-adrenergic receptors ADRB1 and ADRB2 to reduce heart rate and blood pressure. Observational studies have revealed strong risk reductions in metastasis and cancer-specific mortality with the use of beta-blockers in patients with some cancers. But observational studies of prostate cancer have reported conflicting results.

Objectives

We examined the relationship of ADRB1 (Adrenoceptor beta 1) gene expression and ADRB2 (Adrenoceptor beta 2) gene expression with Forkhead box protein A1 (FOXA1) gene expression in prostate cancer. We also analyzed survival data of solid tumor patients with respect to beta 1 (ADRB1) and beta 2 (ADRB2) adrenergic receptor gene expression.

Methods

We examined the genomics of prostate cancer and other solid primary tumors in the GDC TCGA Prostate Cancer (PRAD) data set. The Cancer Genome Atlas (TCGA) contains the analysis of over 11,000 tumors from 33 of the most prevalent forms of cancer.

Results

The presence of somatic mutations [Single nucleotide polymorphisms (SNPs) and small insertion/deletion polymorphism (INDELS)] in FOXA1 alters ADRB1 and ADRB2 gene expression. The correlation of FOXA1 gene expression with ADRB1 and ADRB2 gene expression is highly significant. Alterations in FOXA1 genes, ADRB1 genes, and ADRB2 genes are significantly co-occurrent, indicating that they may work in tandem to drive tumor formation and development. Increased ADRB1 and ADRB2 expressions reduce the overall survival of solid tumor patients in the GDC Pan Cancer set.

Conclusions

FOXA1 signaling may regulate ADRB1 and ADRB2 expression, as well as androgen receptor expression. Analysis of these tumor mutations might indicate whether an individual prostate cancer patient will respond to beta blockers."xsd:string
