Breast Tumor Cells Promotes the Horizontal Propagation of EMT, Stemness, and Metastasis by Transferring the MAP17 Protein Between Subsets of Neoplastic Cells

Scientists explored the role of MAP17 protein shaping tumor evolution and showed that in breast cancer, cells increased MAP17 levels in tumors by demethylation induced multiple changes in gene expression through specific miRNAs downregulation.

Stimulation of Neural Stem Cell Differentiation by Circularly Polarized Light Transduced by Chiral Nanoassemblies

Researchers showed that the differentiation of neural stem cells into neurons could be accelerated by circularly polarized photons when DNA-bridged chiral assemblies of gold nanoparticles were entangled with the cells’ cytoskeletal fibres.

Robust Myelination of Regenerated Axons Induced by Combined Manipulations of GPR17 and Microglia

The authors found that, in injured optic nerves, oligodendrocyte precursor cells undergone transient proliferation but failed to differentiate into mature myelination-competent oligodendrocytes, reminiscent of what was observed in human progressive multiple sclerosis.

The Odorant Receptor OR2W3 on Airway Smooth Muscle Evokes Bronchodilation via a Cooperative Chemosensory Tradeoff between TMEM16A and CFTR

Investigators characterized the effects of a wide range of volatile odorants on the contractile state of airway smooth muscle (ASM) and uncovered a complex mechanism of odorant-evoked signaling properties that regulate excitation-contraction coupling in human ASM cells.

Myocardial Infarction Affects Cx43 Content of Extracellular Vesicles Secreted by Cardiomyocytes

Using a comprehensive strategy that included cell-based approaches, animal models and human patients, scientists demonstrated that myocardial ischemia impairs the secretion of Cx43 into circulating, intracardiac and cardiomyocyte-derived vesicles.

Mitochondrial Pyruvate Carrier Abundance Mediates Pathological Cardiac Hypertrophy

Researchers showed that mitochondrial pyruvate carrier (MPC) abundance mediates pathological cardiac hypertrophy. MPC abundance was reduced in failing hypertrophic human hearts, as well as in the myocardium of mice induced to fail by angiotensin II or through transverse aortic constriction.

FoxO Maintains a Genuine Muscle Stem-Cell Quiescent State until Geriatric Age

In homeostatic skeletal muscle, scientists identified two quiescent stem-cell states distinguished by relative CD34 expression: CD34High, with stemness properties, and CD34Low, committed to myogenic differentiation.
