ARTICLE HIGHLIGHTS
Research background

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies. The mechanism of ESCC is still unclear.

Research motivation

Kinesin family member (KIF)C3 has microtubule motor activity and may be involved in mitotic progression. KIFC3 was also shown to be involved in cell invasion and migration, as well as in survival, in hepatocellular carcinoma.

Research objectives

To elucidate the role of KIFC3 in ESCC and the underlying mechanisms.

Research methods

The expression of KIFC3 was evaluated in ESCC tissues and normal tissues. In addition, KIFC3 knockdown and KIFC3-overexpressing cell lines were constructed and then colony formation, EdU assays, cell cycle analysis, Transwell assays, and western blotting were performed to explore the underlying mechanisms of action. A xenograft tumor model in nude mice was used to verify the role of KIFC3 in tumorigenesis.

Research results

We showed that KIFC3 was upregulated in ESCC tissues and was associated with poor prognosis. KIFC3 promoted cell proliferation, mitosis progression, migration and invasion. In addition, KIFC3 knockdown suppressed ESCC tumorigenesis in an in vivo model. Mechanistically, we validated the involvement of KIFC3 β-catenin signaling and epithelial–mesenchymal transition (EMT) in ESCC progression.

Research conclusions

We found that KIFC3 was overexpressed in ESCC, and the expression of this protein was associated with prognosis in ESCC patients. Furthermore, KIFC3 promoted proliferation, migration, and invasion of ESCC via β-catenin signaling and EMT.

Research perspectives

Although the detailed mechanism underlying the effect of KIFC3 in promoting ESCC progression should be studied more carefully in our next research, we believe our research strongly suggests that KIFC3 may be a potential new therapeutic target for ESCC treatment.
