Expression of MATAL1, miR-106a-5p, and REEP5 in serum. A Comparison of the expression levels of target genes in the serum of TNBC patients without lymph node metastasis and healthy women; B comparison of the expression levels of target genes in the serum of TNBC patients with 1–3 lymph node metastasis and healthy women; C comparison of the expression levels of target genes in the serum of TNBC patients with ≥ 4 lymph node metastasis and healthy women; D the relationship between the expression level of target genes and the degree of lymph node metastasis. *: p < 0.05; **: p < 0.01; ***: p < 0.001
