Translating the effects of mTOR on secretory senescence   pp1230 - 1232
Kosuke Tomimatsu and Masashi Narita
doi:10.1038/ncb3244
Cellular senescence is often accompanied by the production of secreted proteins that mediate the diverse effects of senescence on the tissue microenvironment. The mammalian target of rapamycin (mTOR), a master regulator of protein synthesis, is now shown to control the senescence-associated secretory phenotype by modulating gene transcription and mRNA translation and stabilization.

STIMATE reveals a STIM1 transitional state   pp1232 - 1234
Robert Hooper and Jonathan Soboloff
doi:10.1038/ncb3245
Decreases in endoplasmic reticulum calcium content are sensed by resident STIM proteins, which can activate plasma membrane Orai channels to facilitate Ca2+ entry. The role of STIMATE, a previously unknown component of the store-operated calcium entry complex, has now been identified and defined.

Network plasticity of pluripotency transcription factors in embryonic stem cells   pp1235 - 1246
Adam Filipczyk, Carsten Marr, Simon Hastreiter, Justin Feigelman, Michael Schwarzfischer et al.
doi:10.1038/ncb3237
Using single-cell profiling of Nanog and Oct4 protein levels in mouse embryonic stem cells, Schroeder and colleagues show that differences in Nanog levels are not correlated with differences in expression of other pluripotency factors and cell fate.

Local and tissue-scale forces drive oriented junction growth during tissue extension   pp1247 - 1258
Claudio Collinet, Matteo Rauzi, Pierre-François Lenne and Thomas Lecuit
doi:10.1038/ncb3226
Lecuit and colleagues use live imaging and laser ablation approaches to show that germ-band extension of the Drosophila embryo is associated with new junction growth, which is dependent on both tissue-level and local forces.

ATM functions at the peroxisome to induce pexophagy in response to ROS   pp1259 - 1269
Jiangwei Zhang, Durga Nand Tripathi, Ji Jing, Angela Alexander, Jinhee Kim et al.
doi:10.1038/ncb3230
Zhang et al. report that in response to ROS, ATM regulates peroxisome homeostasis through the phosphorylation of PEX5, which is then ubiquitylated and can be recognized by p62 to specifically activate pexophagy.

An interconnected hierarchical model of cell death regulation by the BCL-2 family   pp1270 - 1281
Hui-Chen Chen, Masayuki Kanai, Akane Inoue-Yamauchi, Ho-Chou Tu, Yafen Huang et al.
doi:10.1038/ncb3236
Chen et al. produced a quadruple knockout of all the known BH3-only proteins in order to characterize their pro-apoptotic functions. They establish that NOXA is a direct activator of BAX/BAK and not merely a sensitizer as previously suggested.

Feedback regulation through myosin II confers robustness on RhoA signalling at E-cadherin junctions   pp1282 - 1293
Rashmi Priya, Guillermo A. Gomez, Srikanth Budnar, Suzie Verma, Hayley L. Cox et al.
doi:10.1038/ncb3239
Yap and colleagues report that robustness of RhoA signalling at E-cadherin junctions is achieved through a feedback network that includes myosin II, ROCK1, Rnd3 and p190B RhoGAP.

Lipid signalling couples translational surveillance to systemic detoxification in Caenorhabditis elegans   pp1294 - 1303
J. Amaranath Govindan, Elamparithi Jayamani, Xinrui Zhang, Peter Breen, Jonah Larkins-Ford et al.
doi:10.1038/ncb3229
Through RNAi screens in C. elegans, Ruvkun and colleagues identify signalling pathways that induce detoxification genes following disrupted translation, suggesting translational surveillance of toxins and virulence factors.

AMPK and PFKFB3 mediate glycolysis and survival in response to mitophagy during mitotic arrest   pp1304 - 1316
Elena Doménech, Carolina Maestre, Lorena Esteban-Martínez, David Partida, Rosa Pascual et al.
doi:10.1038/ncb3231
Malumbres and colleagues reveal that mitotic arrest is accompanied by reduced mitochondrial mass and oxidative respiration resulting in activation of AMPK and induction of glycolysis to promote cell survival.

Pyruvate carboxylation enables growth of SDH-deficient cells by supporting aspartate biosynthesis   pp1317 - 1326
Simone Cardaci, Liang Zheng, Gillian MacKay, Niels J. F. van den Broek, Elaine D. MacKenzie et al.
doi:10.1038/ncb3233
SDH inactivation is associated with cancer susceptibility. Cardaci et al. report a metabolic vulnerability in SDH-deficient cells, by showing that they depend on pyruvate carboxylation for the production of aspartate, proliferation and tumour growth.

Non-canonical NF-κB signalling and ETS1/2 cooperatively drive C250T mutant TERT promoter activation   pp1327 - 1338
Yinghui Li, Qi-Ling Zhou, Wenjie Sun, Prashant Chandrasekharan, Hui Shan Cheng et al.
doi:10.1038/ncb3240
The TERT promoter is mutated in many cancers. Li et al. show that non-canonical NF-κB signalling and ETS1/2 transcription factors are jointly needed to activate the C250T mutant TERT promoter, leading to telomerase activity and glioblastoma growth.

Proteomic mapping of ER-PM junctions identifies STIMATE as a regulator of Ca2+ influx   pp1339 - 1347
Ji Jing, Lian He, Aomin Sun, Ariel Quintana, Yuehe Ding et al.
doi:10.1038/ncb3234
Through a proteomic analysis of ER-PM junctions, Zhou and colleagues and Wang and colleagues discover that the transmembrane protein STIMATE is a positive regulator of STIM localization and function, thereby stimulating Ca2+ influx.

Secreted and O-GlcNAcylated MIF binds to the human EGF receptor and inhibits its activation   pp1348 - 1355
Yanhua Zheng, Xinjian Li, Xu Qian, Yugang Wang, Jong-Ho Lee et al.
doi:10.1038/ncb3222
Lu and colleagues report that the O-GlcNAcylated MIF cytokine binds the extracellular domain of EGFR and prevents EGF-induced EGFR activation. Conversely, EGFR activation leads to MMP13-mediated MIF degradation and EGFR-induced tumorigenesis

Malavika Raman, Mikhail Sergeev, Maija Garnaas, John R. Lydeard, Edward L. Huttlin et al.
doi:10.1038/ncb3238
Through proteomics, Harper and colleagues identify proteins interacting with UBXD adaptors for the multifunctional AAA-ATPase VCP and reveal a role for UBXN10 in ciliogenesis.
