Numerous proteins previously associated with BC were part of this list including, but not limited to hydroxyprostaglandin dehydrogenase 15-(NAD) (HPGD) [36], thymidine phosphorylase (TYMP) [37], annexins (e.g. ANXA1 [38], ANXA5 [39], ANXA10 [40]), alpha actinins (ACTN) (e.g. ACTN1 [41], ACTN4 [42, 43]), membrane-associated progesterone receptor component 1 (PGRMC1) [44], transforming growth factor-beta-induced protein ig-h3 (TGFBI) [45], cadherin 13 (CDH13) [46], or cathepsin E (CTSE) [47], serving as a positive control for the performed study. The gene discussed is HPGD; the disease is breast cancer.
