The purpose of this study is to elucidate the apoptotic activity of Ganoderma lucidum  polysaccharide (GLP) in a human breast cancer cell line MCF-7 in vitro.  According to DPPH assay, GLP showed a good antioxidant (IC 50  value is 202.4 µg/mL). Based on MTT assay, the results showed that GLP inhibits MCF-7 cells proliferation in a dose- and time- dependent manner (p<0.001). IC 50   values of the cytotoxicity of GLP and doxorubin  were 110.907 µg/mL and 58.206 µg/mL respectively. The results from the flow cytometry indicated that GLP could induce apoptotic activity through inducing the up-regulation of the Bax and Caspase-9 and the down-regulation of the BcL-2 in MCF-7 cells. At 2×IC 50 , GLP increased the early-apoptotic and dead cells of MCF-7 from 18.23% to 34.76% and 8.45% to16.34% respectively. In conclusion, the GLP shows anticancer activity against MCF-7 through preventing the proliferation and inducing the apoptosis of MCF-7 cells. Our data provide the potential molecular targets in cancer prevention and reveal the key barriers in the current anticancer drugs development.

AbstractInvasive ductal carcinoma (IDC) constitutes the most frequent malignant cancer endangering women’s health. In this study, a new spontaneously immortalized breast cancer cell line, DHSF-BR16 cells, was isolated from the primary IDC of a 74-years old female patient, treated with neoadjuvant chemotherapy and disease-free 5-years after adjuvant chemotherapy. Primary breast cancer tissue surgically removed was classified as ER−/PR−/HER2+, and the same phenotype was maintained by DHSF-BR16 cells. We examined DHSF-BR16 cell morphology and relevant biological and molecular markers, as well as their response to anticancer drugs commonly used for breast cancer treatment. MCF-7 cells were used for comparison purposes. The DHSF-BR16 cells showed the ability to form spheroids and migrate. Furthermore, DHSF-BR16 cells showed a mixed stemness phenotype (i.e. CD44+/CD24−/low), high levels of cytokeratin 7, moderate levels of cytokeratin 8 and 18, EpCAM and E-Cadh. Transcriptome analysis showed 2071 differentially expressed genes between DHSF-BR16 and MCF-7 cells (logFC > 2, p-adj < 0.01). Several genes were highly upregulated or downregulated in the new cell line (log2 scale fold change magnitude within − 9.6 to + 12.13). A spontaneous immortalization signature, mainly represented by extracellular exosomes-, plasma membrane- and endoplasmic reticulum membrane pathways (GO database) as well as by metabolic pathways (KEGG database) was observed in DHSF-BR16 cells. Also, these cells were more resistant to anthracyclines compared with MCF-7 cells. Overall, DHSF-BR16 cell line represents a relevant model useful to investigate cancer biology, to identify both novel prognostic and drug response predictive biomarkers as well as to assess new therapeutic strategies.
