Objective:
To explore the correlation between tumor-associated macrophages and the proliferation and invasion of type I endometrial carcinoma.
Methods:
Immunohistochemistry was used to investigate the infiltration of macrophages in normal and different types of hyperplastic endometrial lesions. The proliferation and invasion ability of type I endometrial carcinoma cell line RL95-2 influenced by mononuclear macrophage cell line THP-1 (constructed M2 type macrophages) was detected by CCK8 and transwell technologies respectively. Transwell was used to evaluate the recruiting ability of RL95-2 on THP-1 cells. Otherwise, the western blot was also used to detect the expression of CyclinD1 and MMP-2 in RL95-2 with the influence of THP-1.
Results:
Immunohistochemistry result showed a positive correlation between the number of infiltrating macrophages and the progression of endometrial hyperplasia. THP-1 recruited by RL95-2 could promote its proliferation and invasion and enhance the expression of the CyclinD1 and MMP-2 protein in a time dependent manner (P < 0.05).
Conclusions:
Increase of the number of infiltrating macrophages and its contribution to the tumor inflammatory microenvironment may result in the development of the type I endometrial carcinoma.
