Abstract

To investigate the anti-tumor effect of acridone against breast cancer in vivo and provide a therapeutic agent for treatment of breast cancer. The nude mice xenografted tumor model was established by MCF-7 cells. The mice were randomly divided into four groups. The mice in each group (n=6) were intraperitoneally injected with 0.1 mg/kg saline (low-dose), 0.5 mg/kg (middle-dose) and 1.0 mg/kg (high-dose) of acridone for 21 days, respectively. At the end of the animal experiment, the weight of tumors was recorded to calculate the tumor inhibition rate. The serum hormone levels in peripheral blood were determined using ELISA. Hematoxylin and eosin (HE) staining was used to analyze the histopathological changes. The expression of ABCG2 protein and mRNA were determined by Western blot and RT-PCR, respectively. The inhibition rates of tumor growth in the high-dose, middle-dose, and low-dose groups were 29.18%, 17.21%, and 4.27%, respectively. Compared with control and low-dose group, the tumors growth rate in high-dose and middle-dose groups were decreased significantly. Histologically, the tumors were inhibited in the growth rate, the tissue structure was broken. Estrogen in all groups with acridone treatment decreased, the progeste...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
