Asprosin and meteorin-like protein immunoreactivity in invasive ductal breast carcinoma stages.

Aim: The study aimed to investigate asprosin (ASP) and meteorin-like (METRNL) protein immunoreactivity in invasive ductal breast cancer.

Materials And Methods: Overall, 60 cases of invasive ductal breast cancer (20 cases each of Grade 1, 2 and 3) were evaluated in addition to 20 normal breast tissues obtained from the Pathology Department Archive. ASP and METRNL expressions were assessed using immunohistochemical staining and visualised under a light microscope.

Results: There was a significant difference in ASP and METRNL immunoreactivity among all the groups included in the study (p < 0.001). Cancer tissues with Grade 1, 2 and 3 showed a significant increase in ASP and METRNL immunoreactivity compared with the control group; however, no significant difference was noted among the cancer tissues with Grade 1, 2 and 3.

Conclusions: ASP and METRNL immunoreactivity increased at the cellular level in invasive ductal breast cancer, but there was no difference in immunoreactivity among the breast cancer grades.
