The results showed that KLHL5 expression was not correlated with tumor purity (P = 8.28e−01), B cell (P = 7.92e−01), CD4+ T lymphocytes (P = 2.32e−01), CD8+ T lymphocytes (P = 6.33e−01), macrophages (P = 4.96e−01), or dendritic cell (P = 6.16e−01) level in cholangiocarcinoma (Figure 3A). The gene discussed is CD4; the disease is neoplasm.
