タイトル CD36 Expression Is Associated with Cancer Aggressiveness and Energy Source in Esophageal Squamous Cell Carcinoma.
ジャーナル Ann Surg Oncol
Abstract BACKGROUND:Esophageal squamous cell carcinoma (ESCC) is an important cause of cancer-related death worldwide. CD36, a long-chain fatty acid (FA) receptor, can initiate metastasis in human oral squamous cell carcinoma (SCC), and its expression is associated with poor prognosis in several cancers. The clinical significance of CD36 expression and its function in ESCC remain unknown.
METHODS:We examined the clinical significance of CD36 expression in 160 ESCC samples using immunohistochemical staining. Functional analysis was performed to determine the association between CD36 and ESCC characteristics (proliferative ability, invasive ability, and energy source dependency).
RESULTS:Thirty (18.8%) ESCC cases showed high CD36 expression, indicating a significant association with progression. CD36 suppression inhibited proliferation and invasiveness in ESCC cells. ESCC cells with CD36 suppression used specific essential amino acids (EAAs) as energy sources. Cell viability depended on FAs under CD36 expression. The viability of ESCC cells with CD36 suppression depended on EAAs but not FAs.
CONCLUSIONS:CD36 may be a good biomarker and therapeutic target in ESCC. Our data provide new insights into the basic mechanism of CD36-dependent energy utilization for ESCC survival. CD36 might be a key regulator of the dependency of FAs as energy source in ESCC cells.
