We explored the function of DBF4B at the single-cell level by Cancer SEA (Figure 8A), which showed that DBF4B was negatively correlated with apoptosis, cell cycle, deoxyribonucleic acid damage, deoxyribonucleic acid repair, EMT, oxygen deprivation, invasion, metastasis, proliferation, and Quiescence, and positively correlated with angiogenesis and inflammation. The gene discussed is DBF4B; the disease is cancer.
