In malignant epidermal tumor cells, such as in the cells of ovarian cancer 19, gastric cancer 20, glioblastoma (GBM) 21, and oral squamous cell carcinoma (OSCC) 4, CD36 expression is markedly upregulated, whereas in tumor microvessels, which support tumor development and metastasis, CD36 expression is generally downregulated. The gene discussed is CD36; the disease is gastric cancer.
