Successful treatment with a combination of anti-VEGFR2 and anti-PD-L1 antibodies induced high endothelial venules (HEVs) in PyMT (polyoma middle T oncoprotein) breast cancer and RT2-PNET (Rip1-Tag2 pancreatic neuroendocrine tumors), but not in glioblastoma (GBM).
Taken together, these results indicate that 2-DG enhances TRAIL-induced apoptosis in breast cancer cells by multiple mechanisms including suppression of RIP1, and highlight the potential therapeutic benefit of combinations of 2-DG and TRAIL in the treatment of breast cancer.
We used HuR RIP-Chip as a comprehensive and systematic method to survey breast cancer target genes in both MCF-7 (estrogen receptor positive, ER+) and MDA-MB-231 (estrogen receptor negative, ER-) breast cancer cell lines.
Furthermore, employing the RIP-Chip assay yielded 595 transcripts with significantly altered binding to HuR in the more tumorigenic breast cancer clones compared with the weakly tumorigenic clones.
The purpose of this study was to determine the expression of PDX-1 and its effect on RIP activation in two human breast cancer cell lines, AU565 and T47D.
