Gallusser et al. present a new pipeline to train a convolutional neural network for rapid and efficient automated detection of intracellular structures of wide range in size and complexity imaged by volume electron microscopy.

Danilo Lopes, Alexandre L. Seabra, Bernardo Orr, Helder Maiato
Lopes et al. perform a pilot dissection of the cancer tubulin code in the NCI-60 cancer cell panel that identifies high α-tubulin acetylation as a biomarker of taxol response and unveils a mechanistic link between α-tubulin detyrosination and the suppression of MCAK activity in taxol-induced cytotoxicity.
Article
Sha Sun, Xia Li, Malaiyalam Mariappan
Sun et al. show that proteins with marginally hydrophobic signal sequences pause at the Sec61 translocon on their way into the ER and require Sec63/BiP to overcome the pause and facilitate subsequent protein folding in the ER, which prevents protein aggregation during BiP deficiency.

Progressive accrual of senescent cells in aging and chronic diseases is associated with detrimental effects in tissue homeostasis. We found that senescent fibroblasts and epithelia were not only refractory to macrophage-mediated engulfment and removal, but they also paralyzed the ability of macrophages to remove bystander ...

Laiman et al. discover that GSK3α, but not GSK3β, phosphorylates dynamin-2 to unleash the Bin1 inhibition and promotes GLUT4 endocytosis in skeletal muscle. Importantly, pharmacological inhibition of GSK3α improves insulin sensitivity and glucose tolerance in diet-induced diabetic mice, highlighting GSK3α as a therapeutic target for metabolic disorders.
Article
Clotilde Huet-Calderwood, Felix E. Rivera-Molina, Derek K. Toomre, David A. Calderwood
Combining live TIRF microscopy and fluorescently tagged fibronectin, the authors show that fibronectin secretion by fibroblasts occurs preferentially at leading edge protrusions stabilized by mature focal adhesions and that fibronectin deposition requires both intact microtubules and myosin II contractility.
Article
Jonathan Pacheco, Anna C. Cassidy, James P. Zewe, Rachel C. Wills, Gerald R.V. Hammond
Pacheco et al. demonstrate that unbound PI(4,5)P2 diffusion in the PM is rapid and is not slowed by the majority of PI(4,5)P2-dependent PM complexes found there, such as clathrin-coated structures and focal adhesions.
