Targeting the Wnt-Regulatory Protein CTNNBIP1 by MicroRNA-214 Enhances the Stemness and Self-Renewal of Cancer Stem-Like Cells in Lung Adenocarcinomas Researchers report that microRNA-214 (miR-214) contributes to cell self-renewal by directly targeting CTNNBIP1, a member of the Wnt signaling pathway. They demonstrated that miR-214 overexpression enhances stem-like properties in lung adenocarcinoma (LAC) cells and that miR-214 shows increased expression in cancer stem-like cells derived from primary tumor tissue and from two LAC cell lines. [Stem Cells] Abstract Hyaluronic Acid Engineered Nano-Micelles Loaded with 3, 4-Difluorobenzylidene Curcumin for Targeted Killing of CD44+ Stem-Like Pancreatic Cancer Cells The anticancer activity of 3, 4-difluorobenzylidene curcumin loaded nano-micelles against MiaPaCa-2 and AsPC-1 human pancreatic cancer cells revealed dose-dependent cell killing. Results of cellular internalization further confirmed better uptake of hyaluronic acid engineered nano-micelles in triple-marker positive pancreatic cancer stem-like cells compared with triple-marker negative counterparts. [Biomacromolecules] Abstract Mammary Stem Cells and Tumor-Initiating Cells Are More Resistant to Apoptosis and Exhibit Increased DNA Repair Activity in Response to DNA Damage Scientists investigated the molecular and physiological consequences of DNA damage in wild-type mammary stem cells (MaSCs), p53-null MaSCs, and p53-null TICs. They showed that wild-type MaSCs and basal cells are more resistant to apoptosis and exhibit increased non-homologous end joining activity. [Stem Cell Rep] Full Article | Graphical Abstract Knockdown of NAT12/NAA30 Reduces Tumorigenic Features of Glioblastoma-Initiating Cells While decreased expression of the distal 3’UTR of NAT12/NAA30 was generally observed in glioblastoma-initiating cells (GICs) and glioblastomaa (GBMs), this gene was strongly up-regulated at the protein level in GBM and GICs. The increased protein levels were not caused by increased levels of the steady state mRNA but rather by other mechanisms. [Mol Cancer] Full Article Comparative Study of the Effects of PEGylated Interferon-α2a versus 5-Fluorouracil on Cancer Stem Cells in a Rat Model of Hepatocellular Carcinoma Investigators evaluated the effects of PEGylated interferon-α2a and 5-fluorouracil on the expression of cancer stem cell (CSC) markers and on specific pathways that contribute to the propagation of CSCs in hepatocellular carcinoma. [Tumour Biol] Abstract Curcumin Improves the Tumoricidal Effect of Mitomycin C by Suppressing ABCG2 Expression in Stem Cell-Like Breast Cancer Cells The authors investigated the potential of curcumin to reduce breast cancer stem cell (BCSC) population for sensitizing breast cancer cells to mitomycin C both in vitro and in vivo. [PLoS One] Full Article Rescue of Targeted Nonstem-Like Cells from Bystander Stem-Like Cells in Human Fibrosarcoma HT1080 Cancer stem-like cells and nonstem-like cancer cells were co-cultured, and defined cell types were chosen and irradiated, respectively, with proton microbeam. The bidirectional rescue effect in the combinations of the two cell types was then investigated. [Radiat Res] Abstract Pristimerin Inhibits Prostate Cancer Bone Metastasis by Targeting PC-3 Stem Cell Characteristics and VEGF-Induced Vasculogenesis of BM-EPCs The effect of pristimerin on PC-3 stem cell characteristics and metastasis were detected by spheroid formation, CD133 and CD44 protein expression, matrix-gel invasive assay and colony-formation assay in vitro, VEGF and pro-inflammatory cytokines expression by ELISA assay, and tumor tumorigenicity by X-ray and MR in NOD-SCID mice model in vivo.
