Investigators report a novel therapeutic strategy that preferentially targets tumor-initiating cells (TICs) in small cell lung cancer in which cisplatin is combined with CBL0137, an inhibitor of the histone chaperone facilitates chromatin transcription (FACT), which is highly expressed in TICs.

Scientists demonstrated that Snail represses stemness in glioma stem cells. Snail interacted with SMAD signaling mediators, generated a positive feedback loop of bone morphogenetic protein (BMP) signaling and transcriptionally repressed the transforming growth factor β (TGFB)1 gene, decreasing TGFβ1 signaling activity. [Oncogene]
Preclinical models of triple-negative breast cancer (TNBC) were used to test the hypothesis that increased leptin signaling drives obesity-associated TNBC development by promoting CSC enrichment and/or epithelial-to-mesenchymal transition (EMT). [Mol Cancer Res]
Scientists revealed that Abrus agglutinin (AGG) induces colon CSCs differentiation, enhancing sensitivity to anticancer therapeutics. The low dose AGG decreased the expression of stemness-associated molecules such as CD44 and β-catenin in HT-29 cell derived colonospheres. [Mol Carcinog]
Researchers utilized a series of in vitro, in vivo and patient-derived organoid approaches to systematically investigate the chemoprotective role of OPCs in colorectal cancer. OPCs exerted anti-tumorigenic effects through inhibition of cellular proliferation, and induced apoptosis and cell cycle arrest. [Sci Rep]
The authors compared the characteristics of low ATP-binding cassette subfamily G member 2 (ABCG2–) and high (ABCG2+)-ABCG2-expressing pancreatic ductal adenocarcinoma (PDAC) cells after cell sorting. In adherent culture condition, human PDAC cells, PANC-1, contained approximately 10% ABCG2+ cell populations, and ABCG2+ cells displayed more and longer microvilli compared with ABCG2– cells.

Cancer stem-like cells were induced from a human hepatoma cell line in a unique medium containing neural survival factor-1. Splenic injection of cells into immune-deficient mice was used to assess hematogenous liver metastasis. [Cancer Sci]
ST6 beta-galactoside alpha-2,6-sialyltransferase 1 (ST6Gal-I) levels were determined in colorectal carcinoma (CRC) specimens, compared to paired normal colorectal tissue, and examined in CD133+ vs CD133− CRC cells, and CD44+ vs CD44− CRC cells. [Clin Transl Oncol]
Researchers investigated the effect of hyperthermia, 6 MeV electron radiation and combination of these treatments on cancer cell line DU145 in both monolayer culture and spheroids enriched for prostate CSCs. [Radiat Environ Biophys]
The authors describe metabolic futures of CSCs with a special focus on lipid metabolism, which until now represents an underappreciated force in maintaining CSCs and an attractive therapeutic target. [Oncogene]

The University of Pittsburgh (Pitt) and University of Pittsburgh Medical Center (UPMC) announced plans to establish the new UPMC Immune Transplant and Therapy Center, with much of its activity planned within an eight-story innovation hub—all part of a concerted effort to harness the power of the human immune system to treat and cure a wide range of diseases. [The University of Pittsburgh Medical Center]
Cancer Research UK announced that £45 million will be invested into its network of clinical trials units across the UK, one of the charity’s largest investments in clinical research to date. [Cancer Research UK]
Tens of thousands of UK researchers are expected to walk out of their universities in a nationwide strike over pensions that is likely to disrupt scientific experiments, conferences and lectures. [Nature News]
Fresh off a plane from the NATO meeting in Munich, where he’d conferred with world leaders on global defense, former U.S. Vice President Joe Biden issued a forceful call here last night to build on the “Cancer Moonshot” he started while in the White House and transform the way the world fights cancer. [ScienceInsider]
A job that’s been held by some of the nation’s top scientists is now occupied by a 31-year-old politics major from Princeton University. And it’s unlikely to change soon, observers say, leaving President Trump without a science advisor as the administration wrestles with a severe outbreak of the flu, lead-poisoned drinking water and record-breaking disasters that many scientists say are sharpened by rising temperatures.
