ADRB1 and breast cancer: The co-analysis of tumor mutational load and immune infiltration revealed ADRB1 as a possible biomarker for breast cancer.[25] As a result, activating ADRB1 may protect against neuroinflammatory disorders.[26] In human tumor samples, the expression of ADRB2 was elevated in tumor tissues and linked favorably with tumor size, histological grade, lymph node metastasis, and clinical stage.
