A Constant Pool of Lgr5+ Intestinal Stem Cells Is Required for Intestinal Homeostasis

Using a Lgr5-2A-DTR model, which ablates Lgr5+ cells with near-complete efficiency and retains endogenous levels of Lgr5 expression, researchers showed that persistent depletion of Lgr5+ intestinal stem cells in fact compromised small intestinal epithelial integrity and reduced epithelial turnover in vivo.

Circular RNA FLNA Acts as a Sponge of miR-486-3p in Promoting Lung Cancer Progression via Regulating XRCC1 and CYP1A1

Investigators found that miR-486-3p was low-expressed in lung cancer. miR-486-3p, which has been found to target XRCC1 and CYP1A1, was regulated by circFLNA. CircFLNA was located in the cytoplasm and had a high expression in lung cancer cells.

Application of Green Tea Catechins, Polysaccharides, and Flavonol Prevent Fine Dust Induced Bronchial Damage by Modulating Inflammation and Airway Cilia

While searching for an anti-fine dust particle (FDP) reagent, scientists found that green tea extract and fractions rich in flavonol glycosides and crude tea polysaccharides had protective effects against FDP-stimulated cellular damage in the BEAS-2B airway epithelial cell line.

Inflammation-Driven Deaminase Deregulation Fuels Human Pre-Leukemia Stem Cell Evolution

Comparative whole-genome and whole-transcriptome sequencing analyses of FACS-purified pre-leukemia stem cells from myeloproliferative neoplasm patients reveal APOBEC3C upregulation, an increased C-to-T mutational burden, and hematopoietic stem and progenitor cell proliferation during progression, which can be recapitulated by lentiviral APOBEC3C overexpression.
