Essential Role of the Cancer Stem/Progenitor Cell Marker Nucleostemin for Indole-3-Carbinol Anti-Proliferative Responsiveness in Human Breast Cancer Cells
Scientists provide evidence that a natural anti-cancer compound mediates its cellular and in vivo tumor anti-proliferative responses by selectively stimulating cellular interactions of the stem/progenitor cell marker nucleostemin with murine double mutant 2, which frees p53 to trigger its apoptotic response.

The Forkhead Transcription Factor FOXM1 Promotes Endocrine Resistance and Invasiveness in Estrogen Receptor-Positive Breast Cancer by Expansion of Stem-Like Cancer Cells
Increased expression of FOXM1 was associated with an expansion of the cancer stem-like cell population and with increased cell invasiveness and resistance to endocrine treatments. [Breast Cancer Res]

C-Glycoside Mimetics Inhibit Glioma Stem Cell, Proliferation, Migration and Invasion
Researchers report the design and synthesis of C-glycoside mimetics subset of the recently published phostines belonging to the [1,2]-oxaphosphinane core. The hit compound 5.3d inhibited invasion and migration on fibronectin, vitronectin and laminin on both GBM stem cells and GBM cancer cell lines. [J Med Chem] Abstract

miR-152 Functions as a Tumor Suppressor in Glioblastoma Stem Cells by Targeting
Krüppel-Like Factor 4
Scientists explored the potential role of miR-152 in glioblastoma stem cells (GSCs) as well as the possible molecular mechanisms. Their results proved that miR-152 was down-regulated in human GSCs. [Cancer Lett] Abstract

Transient TNF Regulates the Self-Renewing Capacity of Stem-Like Label-Retaining Cells in Sphere and Skin Equivalent Models of Melanoma
Scientists tested the hypothesis that inflammatory factors affect the cancer stem cell (CSC) compartment responsible for tumor development and relapse. Using an inducible histone 2B-GFP fusion protein as a tracer of cell divisional history, they determined that tumor necrosis factor (TNF), which is a classical pro-inflammatory cytokine, enlarged the CSC pool of GFP-positive label-retaining cells in tumor-like melanospheres.

ALDH1A1 Maintains Ovarian Cancer Stem Cell-Like Properties by Altered Regulation of Cell Cycle Checkpoint and DNA Repair Network Signaling
Scientists evaluated aldehyde dehydrogenase (ALDH)⁺ ovarian cancer stem cell-like properties and their role in platinum resistance. Isogenic ovarian cancer cell lines for platinum sensitivity and platinum resistant as well as ascites from ovarian cancer patients were analyzed for ALDH⁺ by flow cytometry to determine its association to platinum resistance, recurrence and survival.

Esophageal Cancer Stem Cells Express PLGF to Increase Cancer Invasion through MMP9 Activation
Researchers used a human esophageal cancer cell line, TE-1, to examine the cross talk of placental growth factor (PLGF) and matrix metalloproteinase 9 (MMP9). They found that the levels of PLGF in TE-1 cells positively affected the levels of MMP9, while the levels of MMP9 did not affected the levels of PLGF, suggesting that PLGF may activate MMP9 in esophageal cancer cells.
