EGFR is aberrantly activated in many cancer types. Here the authors show that small GTPase ARF6 mediates the trafficking of palmitoylated EGFR from Golgi to plasma membrane and the blockade of this sorting system inhibits the growth of EGFR overexpression tumours.

Developing stable single-atom catalysts (SACs) with a high metal loading remains a challenge due to the difficulty of creating high densities of defects on support materials. Here the authors prepare Pt SACs with high Pt loadings by virtue of strong covalent metal-support interaction, rather than support defects.

The application of STING agonists and the blockade of the SIRPα–CD47 signaling axis are emerging immunotherapeutic strategies. Here the authors show that hybrid cellular membrane nanovesicles loaded with a STING agonist or overexpressing high-affinity SIRPα variants can be exploited to promote anti-tumor immune responses.

Aberrant EGFR expression is associated with triple-negative breast cancer (TNBC). Here the authors identify that TMEM25 interacts with EGFR and the loss of TMEM25 allows monomeric EGFR-mediated hyperactivation of STAT3 to promote TNBC progression.

The molecular mechanisms underlying contextual fear memory consolidation by sparse dentate gyrus (DG) neuronal populations remain unclear. Here using unbiased RNA sequencing of DG engram neurons the authors identify persistent transcriptome modifications during memory consolidation, in which CREB-dependent transcription features prominently

Activating mutations of BRAF alone are inadequate to drive melanoma formation. Here the authors show that activation of Hippo signalling by oncogenic BRAF represents an additional safeguard to limit BRAF-dependent human melanocyte growth and melanoma formation.

Waterlogging tolerance is important in direct seeding rice cultivation practice. Here, the authors identify a 14-3-3 protein-coding gene OsGF14h in weedy rice that confers anaerobic germination and anaerobic seedling development tolerance by balancing ABA signaling and GA biosynthesis.

Here, the authors show that a CEP128 variant observed in human male siblings causes reduced sperm counts and morphologically abnormal sperm when modeled in mice, suggesting a role for CEP128 in male fertility.

AML1-ETO is a fusion protein in which acetylation of lysine-43 is critical to leukemogenesis. Here, they show that TAF1 is required for AML1-ETO mediated gene expression such that it binds to acetylated AML1-ETO to facilitate the association of AML1-ETO with chromatin, and consequently, promotes leukemic self-renewal.
