Scientists identified the MYST acetyltransferase HBO1 and several known members of the HBO1 protein complex as critical regulators of leukemia stem cell maintenance. [Nature]
Researchers found that CD8 T cells within tumors consisted of distinct populations of terminally differentiated and stem-like cells. On proliferation, stem-like CD8 T cells gave rise to more terminally differentiated, effector-molecule-expressing daughter cells. [Nature]
Elevated Tribble 3 expression supported breast cancer stem cells by interacting with AKT to interfere with the FOXO1-AKT interaction and suppressed FOXO1 phosphorylation, ubiquitination, and degradation by E3 ligases SKP2 and NEDD4L. [Nat Commun]
The peptide F3, derived from phage display, promoted the fast and efficient internalization of a genetically fused GFP inside MDA-MB-231 cancer stem cells, in a specific receptor-dependent fashion. [ACS Appl Mater Interfaces]
The authors showed that Arid1a conditional knockout mice had a high incidence of squamous cell carcinoma occurring in the tongue and esophagus. ARID1A depletion promoted tumor initiation and cancer stemness in human squamous cell carcinoma cells. [Cell Death Differ]
Researchers showed that krüppel-like factor 4 (KLF4) overexpression was accompanied with stemness and mesenchymal features in Lgr5+CD44+EpCAM+ colorectal cancer stem cells. [J Cell Mol Med]
Scientists performed 3-dimensional assays for investigating the collective invasion from cancer cell spheroids. They demonstrated that cancer stem-like cells could promote both collective and single cell invasion significantly. [Cancer Sci]
Investigators examined the role of heparan sulfate in prostate stem/progenitor cell self-renewal and prostate regeneration. They found that deletion of the glycosyltransferase exostosin 1 abolished heparan sulfate expression in prostate stem/progenitor cells and disrupted their ability to self-renew. [Glycobiology]
Researchers report that TGF-β-induced factor homeobox 2 (TGIF2) mediated the EGFR-RAS-ERK signaling pathway to enhance the stemness of lung adenocarcinoma cells and, therefore, promoted the progression and metastasis of lung adenocarcinoma. [Signal Transduct Target Ther]
The authors review studies that focus on melanoma immunotherapies, rendering aldehyde dehydrogenase a potential marker to evaluate the efficacy of anti-neoplastic therapies or an adjuvant anti-melanoma target. [Mol Biol Rep]

Two grants for research that could transform cancer therapies have been funded through an innovative partnership between the American Association for Cancer Research (AACR) and MPM Capital through its management of the UBS Oncology Impact Fund. [American Association for Cancer Research]
Basilea Pharmaceutica Ltd. announced that it plans to advance the clinical development of its novel tumor checkpoint controller lisavanbulin (BAL101553) by focusing on a targeted, biomarker-driven approach based on the initial results from the two recent Phase I/II clinical studies. [Basilea Pharmaceutica Ltd.]
For the 2020 fiscal year, most US research agencies will receive a funding increase, according to details of a spending bill released by Congress. A total of $2.8 billion of the NIH budget, a boost of $330 million over this year, will be earmarked for Alzheimer’s research, with another $12.5 million for firearm injury and mortality protection research. [The Scientist]
Another year, another 1,433 (and counting) retractions. The tenth year of Retraction Watch’s existence included-as is often the case-a new record, some impressive numbers, and some bizarre stories. But it also included some exemplary behavior. [The Scientist]
Recommendations put forth by the Working Group on Changing the Culture to End Sexual Harassment include requiring NIH-funded institutions to notify the agency within two weeks when a grant recipient is found guilty of sexual misconduct, barring confirmed harassers from serving on NIH advisory councils, and mandating that grant applicants report sexual harassment findings against them. [The Scientist]
Success in science requires building top performing teams to push the boundaries of what is known-and this means attracting and nurturing scientific talent. In today’s political climate of possible scientific funding cuts and immigration policy uncertainty, headlines forecast a grim effect on scientific research. [Scientific American]
