Objective:
The purpose of this study was to detect ferritin light chain (FTL) expression level in osteosarcoma (OS), and to clarify whether FTL could offer additional help in diagnosis or therapy.
Materials And Methods:
First, we assessed FTL level in OS tissues and cells through GEO dataset and tissue microarrays (TMAs). Then, we overexpressed FTL expression in MG-63 cell line. Lastly, we detected the expression of EMT-related signal pathway proteins to study its underlying molecular mechanisms.
Results:
GEO dataset and TMAs showed that FTL was down-regulated in OS. After FTL was overexpressed, the proliferation, migration and invasion abilities of OS cells were significantly reduced. Moreover, after FTL overexpressing, the levels of CDH2 and Vimentin were down-regulated with CDH1 up-regulated.
Conclusions:
We revealed that FTL (1) is lower in OS then in normal tissue, (2) is related to metastasis, survival period, and therapeutic response, and (3) may be a tumor-inhibiting factor owing to its inhibition of EMT in OS.
