FABP5 and invasive breast carcinoma: To further investigate the role of FABP5 in invasive breast cancer, we first analyzed the correlation between FABP5 expression in tumor cells and various clinical parameters, including age (Fig. 5A), BMI (Fig. 5B), tumor size (Fig. 5C), tumor Elston-Ellis grade (Fig. 5D), metastasis (Fig. 5E) and patient vital status (Fig. 5F).
