Late-stage tumors induce anemia and immunosuppressive extramedullary erythroid progenitor cells
Large tumors induce anemia and expansion of CD45+ immature erythroid cells, which represent a major immunosuppressive population in the spleen, contributing to systemic suppression of T cell immunity in late-stage cancer. Expand
Ovarian cancer stem-like cells differentiate into endothelial cells and participate in tumor angiogenesis through autocrine CCL5 signaling.
This study found that ovarian cancer stem-like cells (CSLCs) activate the NF-κB and STAT3 signal pathways through autocrine CCL5 signaling and mediate their own differentiation into endothelial cells (ECs), and provides a novel strategy for anti-angiogenesis in ovarian cancer. Expand
EZH2 Inhibitor GSK126 Suppresses Antitumor Immunity by Driving Production of Myeloid-Derived Suppressor Cells.
It is reported that suppressing EZH2 activity using GSK126 resulted in increased numbers of myeloid-derived suppressor cells (MDSC) and fewer CD4+ and IFNγ+CD8+ T cells, which are involved in antitumor immunity, and suggested that modulating the tumor immune microenvironment may improve the efficacy of EZh2 inhibitors.

Aberrant elevated microRNA-146a in dendritic cells (DC) induced by human pancreatic cancer cell line BxPC-3-conditioned medium inhibits DC maturation and activation
It is indicated that aberrant miRNA-146a expression is one of main factors responsible for inhibition of DC maturation and antigen presentation function, and this inhibitory effect on DCs may be due to the repression of Smad4 mediated signal pathway by BxCM. Expand
Targeting EZH2 histone methyltransferase activity alleviates experimental intestinal inflammation
It is shown that EZH2 inhibitors attenuate experimental colitis in mice by promoting the development of myeloid-derived suppressor cells, and delay the onset of colitis-associated cancer. Expand
microRNA-214 promotes epithelial-mesenchymal transition and metastasis in lung adenocarcinoma by targeting the suppressor-of-fused protein (Sufu)
This study finds that the expression of miR-214 was elevated in LAD and correlated positively with LAD metastasis and epithelial-mesenchymal transition (EMT), and uncovers a previously unappreciated mi R-214-Sufu pathway in controlling EMT and metastasis of LAD. Expand
