TOP STORYScientists demonstrated that interleukin-7 receptor (IL-7R) expression was an early functional biomarker of T-cell acute lymphoblastic leukemia (T-ALL) cells with leukemia-initiating cell potential, and demonstrated that impaired IL-7R signaling hampered engraftment and progression of patient-derived T-ALL xenografts.

PUBLICATIONS(Ranked by impact factor of the journal)The FBXW2-MSX2-SOX2 Axis Regulates Stem Cell Property and Drug Resistance of Cancer Cells The authors established an FBXW2-MSX2-SOX2 axis and found it regulated cancer stem cell property and drug resistance. Specifically, FBXW2 or SOX2 promoted tumor sphere formation and tamoxifen resistance, which was blocked by MSX2. [Proc Natl Acad Sci USA] Abstract ZR2002 induced submicromolar anti-proliferative effects and inhibited neurosphere formation of all glioblastoma stem cells with marginal effects on normal human astrocytes. [Clin Cancer Res] Abstract Diminished AHR Signaling Drives Human Acute Myeloid Leukemia Stem Cell Maintenance Scientists showed aryl hydrocarbon receptor (AHR) signaling was repressed in human acute myeloid leukemia (AML) blasts and preferentially downregulated in leukemic stem cell (LSC)-enriched populations within leukemias. A core set of AHR targets was uniquely repressed in LSCs across diverse genetic AML subtypes. [Cancer Res] Abstract Investigators present a novel ex vivo 3D system for culturing circulating tumor cells from breast cancer patient blood samples using porous poly(ε-caprolactone) scaffolds. [J Clin Med] Full Article Researchers confirmed the pro-tumoral effect of programmed cell death ligand-1 on human glioma cell survival, stemness capacity and resistance, and addressed the issue of whether, by targeting its foldase either chemically or by silencing, the aggressive tumor features could be attenuated. [Cell Death Discov] Full Article Scientists examined the effects of the milk protein alpha-casein over expression in the triple negative MDA-MB-231 breast cancer cell line. The effects of recombinant alpha-casein added exogenously to MDA-MB-231 breast cancer cells, and immortalized human fibroblasts were also investigated. [J Mammary Gland Biol Neoplasia] Full Article The authors investigated the usefulness of a novel metastatic renal cell carcinoma 3D spheroid culture for in vitro CSC physiology research and drug toxicity screening. [Oncol Rep] Abstract | Download Full Article HER2 Regulates Cancer Stem Cell Activities via the Wnt Signaling Pathway in Gastric Cancer Cells Human epidermal growth factor 2 (HER2) was transfected into MKN28 gastric cancer cells, and its role in regulating CSC activity was determined by characterizing HER2-overexpressing cells.

REVIEWSThe authors highlight how activation of HIF signaling, in response to hypoxic conditions within the tumor microenvironment, results in the expression of genes associated with stemness and EMT promoting prostate CSC emergence which ultimately drives tumour relapse to castrate resistant prostate cancer.

POLICY NEWSHow US Sanctions Are Crippling Science in Iran After almost a year of sanctions put in place by US President Donald Trump, Iran is experiencing economic recession, a depreciating currency and high inflation. All of this is stretching budgets for equipment, supplies and travel, endangering research projects and sapping morale, say researchers. [Nature News] Editorial The Potent Effects of Japan’s Stem-Cell Policies A five-year regulatory free-for-all in regenerative medicine has given the industry a boost. But patients might be paying the price. [Nature News] Editorial
