Fig. 5: Autoantibodies against the antigens are increased in patients with breast atypia as compared to patients without breast atypia.

Indirect ELISA of sera from women without breast atypia (nā=ā43) was compared to sera from women undergoing breast surgery for mammographic abnormalities (benign pathology nā=ā12, hyperplasia nā=ā12, fibroadenoma nā=ā36, or DCIS nā=ā59), and women with known breast cancer (nā=ā37). Y axis is ng/mL IgG antibody concentration by ELISA for each antigen and X axis is the breast pathology a VPS35, b ARPC2, c SERBP1, d KRT8, and e PDIA6 Error bars are standard error of mean (SEM) ****pā<ā0.0001, ***pā<ā0.001, **pā<ā0.01, *pā<ā0.05.
