Multi-region sequencing of small cell lung cancers (SCLC) can improve our understanding of the disease. Here the authors analyse 120 multi-region samples from 40 SCLC patients with whole exome sequencing and characterise their mutational burden, evolution, heterogeneity, and potential prognostic biomarkers.

Melting and squeezing pure metals between two sapphires covered in molybdenum disulfide produces diverse two-dimensional metals at the ångström thickness limit.

In a randomized phase 3 trial, neoadjuvant anti-PD-1 plus either paclitaxel and cisplatin or nab-paclitaxel and cisplatin elicited a significantly superior pathological complete response rate versus neoadjuvant paclitaxel and cisplatin alone in patients with resectable locally advanced esophageal squamous cell carcinoma.

The tumour microenvironment features influencing response to neoadjuvant immunochemotherapy (nICT) in esophageal squamous cell carcinoma (ESCC) remain to be explored. Here, single cell and TCR sequencing on pre- and post- nICT treatment ESCC tissues identifies the presence of CXCL13⁺CD8⁺ T cells as a predictor of improved response and the enrichment of TNFRSF4⁺CD4⁺ Tregs as a marker of treatment resistance.

Song and colleagues report that in breast cancer, chemotherapy induces the IRENA lncRNA, which reprograms tumor suppressive macrophages to protumorigenic phenotypes and promotes chemoresistance.

Rational design of the morphology of inorganic microstructures is challenging. Now an electrochemical method is reported for designing the morphology of inorganic microarchitectures via programming of the potential waveforms applied during microstructure growth. These microstructures have potential application as SERS sensors.

Templating method holds great promise for fabricating surface nanopatterns. Here authors present a guiding growth mode using metal-organic framework microparticles as templates during metal electrodeposition, where metals exclusively grow underneath the microparticles.

Hyperferritinemic syndrome is a collective term for a group of severe inflammatory conditions distinguished by high ferritin levels, including adult-onset Still’s disease and COVID-19. Here authors show in an animal model that high ferritin levels are not just a sign of hyperinflammation but also a pathogenic factor that triggers neutrophil leukocyte activation and extracellular trap formation.

A study shows that the three-dimensional conformation of the human genome influences the positioning of DNA replication initiation zones, highlighting cohesin-mediated loop anchors as essential determinants of their precise ___location.

Despite lung adenocarcinoma having a high global mortality, the genetic mutations present in Asian patients are uncharacterized. Here the authors use genomic and transcriptomic analysis to identify thirteen significantly affected genes, including RHPN2, GLI3, MRC2, TP53 and IQGAP3.

Primary small cell carcinoma of the oesophagus has a poor prognosis, and has not been fully characterised molecularly. Here, the authors study the disease using multi-omics technology and find frequent RB1 disruptions and similarities to small cell lung cancer, opening potential therapeutic avenues.

The metallophilic interaction between cyclometalated palladium complexes can facilitate supramolecular nanostructure formation in living mice, providing a phototoxic prodrug with a long circulation time and high tumour-targeting efficiency. Upon green light irradiation, this palladium-based drug destroys solid tumours, leaving non-irradiated organs intact.

The tumour-specific circular RNA FAM53B is highly immunogenic and can induce anti-tumour responses in mouse models of breast cancer and melanoma, expanding the repertoire of anticancer targets for development.

Nanoparticles that can disperse in a broad range of solvents are desirable. Here, the authors report nanoparticles featuring rotatable surface ligands that enable the formation of stable dispersions in a wide range of solvents.

While most broadly neutralizing antibodies (bnAb) against Influenza virus target conserved conformational epitopes of the glycoprotein hemagglutinin (HA), Sun et al. characterize a lineage of bnAbs that neutralize group 1 and 2 strains. Structural characterization shows that antibody 28-12 binds a continuous epitope within H3 (group 2) but requires a conformational epitope for H1 (group 1) binding. Comparison of germline-reverted Ab and intermediate mutants provides evidence for an evolutionary adaptation from group 2 to group 1 strain.

During phosphatidylcholine (PC) remodeling re-acylation is catalyzed by lysophosphatidylcholine acyltransferases (LPCAT). Here, the authors present crystal and cryo-EM structures of chicken LPCAT3 in the apo-, acyl donor-bound and acyl receptor-bound states, and based on the structures and further functional analysis they discuss the mechanism of the enzyme.

A broad-range human antibody with neutralizing activity against various coronaviruses, including SARS-CoV-2, targets a unique epitope within the highly conserved S2’ site and the fusion peptide of the spike protein that is exposed during interaction with the host cell. The pan-coronavirus antibody protects mice against infection with SARS-CoV-2 and HCoV-OC43 following prophylactic and therapeutic treatment.

The distinct genomic and epidemiological features of Chinese lung cancer patients suggest the presence of alternative causal mechanisms. Here, the authors present the genomic landscape of 149 Chinese NSCLC patients and reveal distinct mutational signatures associated with inflammatory microenvironments.

Effective control of tumors requires the presence of inflammatory helper and cytotoxic T cells. Song and colleagues demonstrate that the protein RGS1 cell-intrinsically regulates effector T cell homing to tumors and thereby impairs tumor control.

Circular RNAs (circRNA) is a class of non-coding RNAs that can regulate gene translation and function. Here the authors show that a circRNA, circNDUFB2, is downregulated in non-small cell lung cancer tissues, and likely contributes to anti-tumor immunity by regulating both degradation of oncoproteins and induction of innate immunity.

Skate-specific changes in the epigenome and its three-dimensional organization contributed to the evolution of the batoid fin morphology.

Circular RNAs are known to regulate cancer. Here, the authors show that the circular RNA circTP63 promotes lung squamous cell carcinoma by competing with endogenous RNA to upregulate FOXM1.

The cyclin-dependent kinase inhibitors p18 and p27 confer advantage to the propagation of haematopoietic stem cells (HSCs). In this manuscript, the authors demonstrate that p18 is a potent negative regulator of HSC self-renewal, and identify novel small molecules putatively inhibiting p18 that promote HSC growth in culture and mouse transplant assays.

lncRNAs can regulate immune responses at a number of levels. Song and colleagues demonstrate that the lncRNA NKILA is expressed by tumor-associated cytotoxic T cells, and this predisposes them to activation-induced cell death and escape of tumors from immunologically mediated destruction.

This analysis systematically evaluates cross-linking chemistry and chromatin fragmentation strategies commonly used in 3C assays and introduces an improved Hi-C protocol for detecting loops and compartments.

The Kondo effect can serve as a powerful paradigm to understand strongly correlated many-body processes in physics. Here, Guo et al. utilize single molecule transistor devices as a testbed to study multi-level Kondo correlation and show electrical gate evolution and the universality of the two-stage Kondo effect.

Protein feeding is known to induce strong inhibition on further food intake, though the underlying mechanisms remain poorly understood. Here, the authors identify a protein-specific satiety hormone inDrosophila, and show that it suppresses feeding via promoting DILP2 release in the central nervous system.
