Core Tip

Core Tip: Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a critical factor in promoting intestinal immunity homeostasis. Whether GM-CSF plays a protective role against hepatocellular carcinoma (HCC) by regulating immunity and intestinal microecology is not completely understood. Orthotopic transplantation tumor models of HCC were established in mice by transfecting human GM-CSF sequences into a human HCC cell line using lentivirus. We measureed the absolute abundance of specific fecal bacterial communities using the absolute quantificative 16S rRNA amplicon sequencing technology. This study provides new insights into the therapeutic approaches for HCC.
