This collection highlights recent papers published in Nature Portfolio journals on topics across embryonic development & stem cells, reproductive biology, synthetic tissues & embryo models, clinical & translational research and tissue stem cells.
This themed issue presents a collection of Reviews, Perspectives and Articles that aim to reveal the molecular and chemical principles underlying phase-separated condensate formation and promote the development and use of new tools for the study of phase separation biology.
A workflow integrating tools from bioinformatics, structural biology and synthetic biology has been developed that enables the rapid design of pili-enabled living materials. This approach allows mining of pili-producing nonpathogenic chassis, understanding of the pili structure and assembly, and engineering of pili-enabled living materials in a systematic and sequential manner.
Terpenoids bearing carbon skeletons derived from nonisoprene units are rare and considered noncanonical. Now, a genome-mining study has uncovered previously unknown noncanonical C16 terpenes and their biosynthetic pathways from bacteria. The findings suggest that noncanonical terpenoids are diverse and widespread in nature.

The design of ligand-regulated circuits for plant synthetic biology is limited by the relatively small number of parts available for building genetic circuits49,50. Our * module may address this; however, its utility requires tight insulation of * components from the endogenous ABA signaling machinery. Because ABA signaling has many physiological effects, such as inhibiting seed germination and triggering guard cell closure, cross-activation by the * module could cause numerous unwanted ABA-related phenotypes. Our module incorporates several mutations to limit cross-talk. First, the T162D/V393R orthogonalizing mutations reduce */WT interactions. Second, catalytic inactivation of HAB1* by the D204A mutation prevents it from dephosphorylating SnRK2 kinases and blocking ABA signaling. Third, HAB1* contains two mutations (R505A and V393R) that disrupt its ability to bind SnRK2s45. Lastly, PYR1*MANDI is not activated by ABA due to several mutations in its binding pocket (Fig. 2b,c). We constructed and analyzed 35S::GFP-PYR1*MANDI and 35S::GFP-HAB1* transgenic plants to investigate potential cross-talk. Seed germination and leaf temperatures (which increase due to guard cell closure) of the 35S::GFP-PYR1*MANDI plants are similar to WT after ABA or mandi treatments, unlike a previously constructed 35S::PYR1MANDI positive control25 (Extended Data Fig. 5a,b). Similarly, the leaf temperatures and morphologies of 35S::GFP-HAB1* lines are similar to WT, unlike an ABA-insensitive mutant (abi1-1) positive control (Extended Data Fig. 5c) or the insensitivity phenotypes previously documented when overexpressing HAB1 and related PP2Cs51,52. Collectively, these observations indicate negligible ABA pathway cross-talk by the * module components.

Important advancements in the treatment of non-small cell lung cancer (NSCLC) have been achieved over the past two decades, increasing our understanding of the disease biology and mechanisms of tumour progression, and advancing early detection and multimodal care. The use of small molecule tyrosine kinase inhibitors and immunotherapy has led to unprecedented survival benefits in selected patients. However, the overall cure and survival rates for NSCLC remain low, particularly in metastatic disease. Therefore, continued research into new drugs and combination therapies is required to expand the clinical benefit to a broader patient population and to improve outcomes in NSCLC.
Cofactorless oxygenases are rare in nature and natural product biosynthesis. Here the authors describe the biochemical and structural characterization of two such oxygenases catalyzing deformylation, ring cleavage and epoxidation in the biosynthesis of the enediyne natural product tiancimycin A.
Basement membranes are delicate, nanoscale and pliable sheets of extracellular matrices that often act as linings or partitions in organisms. Previously considered as passive scaffolds segregating polarized cells, such as epithelial or endothelial cells, from the underlying mesenchyme, basement membranes have now reached the center stage of biology. They play a multitude of roles from blood filtration to muscle homeostasis, from storing growth factors and cytokines to controlling angiogenesis and tumor growth, from maintaining skin integrity and neuromuscular structure to affecting adipogenesis and fibrosis. Here, we will address developmental, structural and biochemical aspects of basement membranes and discuss some of the pathogenetic mechanisms causing diseases linked to abnormal basement membranes.
Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P 20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.
