No one type of analytical separation or detection technique is capable of characterizing the entire metabolome at once. A suite of technologies can offer broader and deeper analyses into the metabolome - from sample collection to interpretation.

IQGAP1 makes PI(3)K signalling as easy as PIP, PIP2, PIP3 pp1263 - 1265 Lucia E. Rameh and Ashley M. Mackey doi:10.1038/ncb3440 Despite being one of the most studied signalling pathways, precisely how phospholipid synthesis is regulated in the phosphoinositide signalling cascade remains unclear. The scaffold protein IQGAP1 is now shown to orchestrate the assembly of a multi-enzyme complex that streamlines PtdIns(3,4,5)P3 synthesis to facilitate Akt activation in response to extracellular stimuli.
See also: Article by Choi et al. | | | | Getting a grip on collective cell migration pp1265 - 1267 Tamal Das and Joachim P. Spatz doi:10.1038/ncb3447 Many cell types in our body move in a collective manner, which requires individual cells to align their movements relative to that of their neighbours. A mechanism is now described in which cadherin-rich protrusions are extended from leading migrating cells and engulfed by follower cells to guide collective migration.

Heppert and Bob Goldstein doi:10.1038/ncb3449 Work from the early 1980s reported strange lobes protruding from Caenorhabditis elegans germ cell precursors. However, the fate and potential significance of these lobes remained unexplored for decades. Now, neighbouring endodermal cells are shown to sever and digest these lobes, in an unexpected process of 'intercellular cannibalism', which could play an important part in regulating primordial germ cells.

Direct reprogramming of fibroblasts into renal tubular epithelial cells by defined transcription factors pp1269 - 1280 Michael M. Kaminski, Jelena Tosic, Catena Kresbach, Hannes Engel, Jonas Klockenbusch et al. doi:10.1038/ncb3437 Kaminski et al. demonstrate that combined expression of the transcription factors Emx2, Hnf1b, Hnf4a and Pax8 converts mouse and human fibroblasts into induced renal tubular epithelial cells.

Crumbs2 promotes cell ingression during the epithelial-to-mesenchymal transition at gastrulation pp1281 - 1291 Nitya Ramkumar, Tatiana Omelchenko, Nancy F. Silva-Gagliardi, C. Jane McGlade, Jan Wijnholds et al. doi:10.1038/ncb3442 Ramkumar et al. demonstrate that Crumbs2 is required in the cells of the primitive streak to promote cell ingression during the epithelial-to-mesenchymal transition, and maintains the integrity of the epiblast.

Asymmetric division coordinates collective cell migration in angiogenesis pp1292 - 1301 Guilherme Costa, Kyle I. Harrington, Holly E. Lovegrove, Donna J. Page, Shilpa Chakravartula et al. doi:10.1038/ncb3443 Costa et al. show that asymmetric positioning of the mitotic spindle during endothelial tip cell divisions produces daughter cells of different sizes and the ensuing asymmetry of Vegfr distribution drives Notch-independent tip/stalk cell selection.

Developmentally programmed germ cell remodelling by endodermal cell cannibalism pp1302 - 1310 Yusuff Abdu, Chelsea Maniscalco, John M. Heddleston, Teng-Leong Chew and Jeremy Nance doi:10.1038/ncb3439 Caenorhabditis elegans primordial germ cells (PGCs) transiently extend large lobes, which are found to be actively removed and digested by endodermal cells to alter PGC content in a process dependent on actin and dynamin.

Engulfed cadherin fingers are polarized junctional structures between collectively migrating endothelial cells pp1311 - 1323 Arnold Hayer, Lin Shao, Mingyu Chung, Lydia-Marie Joubert, Hee Won Yang et al. doi:10.1038/ncb3438 Hayer et al. observe that collectively migrating endothelial cells extend rear VE-cadherin-rich membrane structures that are engulfed by follower cells, correlating spatially with the direction of movement.

Agonist-stimulated phosphatidylinositol-3,4,5-trisphosphate generation by scaffolded phosphoinositide kinases pp1324 - 1335 Suyong Choi, Andrew C. Hedman, Samar Sayedyahossein, Narendra Thapa, David B. Sacks et al. doi:10.1038/ncb3441 Anderson et al. show that IQ-motif-containing GTPase-activating protein 1 (IQGAP1) acts as a scaffold for the phosphoinositide kinases that mediate the sequential phosphorylation of phosphoinositides to generate PtdIns(3,4,5)P3 and downstream signalling.

Tissue mechanics promote IDH1-dependent HIF1α-tenascin C feedback to regulate glioblastoma aggression pp1336 - 1345 Yekaterina A. Miroshnikova, Janna K. Mouw, J. Matthew Barnes, Michael W. Pickup, Johnathan N. Lakins et al. doi:10.1038/ncb3429 Weaver and colleagues report that enrichment of the extracellular matrix with tenascin C promotes aggressiveness of IDH1-mutant glioblastoma by activating a HIF1α-controlled mechanosignalling feedback loop.

Lgr6 labels a rare population of mammary gland progenitor cells that are able to originate luminal mammary tumours pp1346 - 1356 Leander Blaas, Fabio Pucci, Hendrik A. Messal, Agneta B. Andersson, E. Josue Ruiz et al. doi:10.1038/ncb3434 Blaas et al. traced Lgr6+ cells during mammary gland formation, homeostasis, pregnancy and tumorigenesis, and found that they represent a population of unipotent progenitors that contribute to alveologenesis and can initiate luminal mammary tumours.

SCAI promotes DNA double-strand break repair in distinct chromosomal contexts pp1357 - 1366 Rebecca Kring Hansen, Andreas Mund, Sara Lund Poulsen, Maria Sandoval, Karolin Klement et al. doi:10.1038/ncb3436 Hansen et al. find that SCAI (suppressor of cancer cell invasion) is a 53BP1-binding protein that acts to repair in heterochromatin and to facilitate meiotic recombination in germ cells.
