Host proteins CPSF6, NUP153, and SEC24C are vital for HIV-1 infection. They bind to the viral capsid protein and contribute to shuttling of virions through the cytoplasm (SEC24C), import into the nucleus (NUP153 and CPSF6) and subsequent trafficking to preferred integration sites (CPSF6). Here, Wei et al. combine structural, biochemical and virological assays to emphasize the importance of prion-like low complexity domains surrounding short phenylalanine-glycine regions in binding and increasing the avidity when interacting with viral capsid.

The enantioconvergent alkylation of oxygen nucleophiles is achieved using α-haloamides and a readily available copper catalyst, and the reaction proceeds under mild conditions in the presence of a wide variety of functional groups.

In the presence of three ligands and light, two distinct copper catalysts combine to produce enantioenriched secondary amides from racemic alkyl electrophiles and primary amide nucleophiles.

Alkyl amines are found in a wide array of bioactive compounds, making strategies for their synthesis very important. Now, a method has been developed to synthesize tertiary alkyl amines via photoinduced, copper-catalysed nucleophilic substitution of unactivated alkyl halides by secondary alkyl amines, with key copper intermediates elucidated in a detailed mechanistic study.

Marra and colleagues describe POG570, a pan-cancer, whole-genome, transcriptome and clinical dataset stressing the molecular interactions in advanced and post-therapy cancer patients.

COVID-19-related non-pharmaceutical interventions impacted the circulation of other pathogens. Here, the authors compile a global viral activity dataset and compare the timing of resurgence of seven common respiratory viruses following the relaxation of interventions across different geographical regions.

A study generates a clinicogenomics dataset resource, MSK-CHORD, that combines natural language processing-derived clinical annotations with patient medical data from various sources to improve models of cancer outcome.

Patient-reported outcome (PRO) measures, such as quality of life, have been associated with relevant clinical end points and are prognostic for survival outcomes in a variety of solid cancers in adults. The authors of this Review comprehensively assess the correlation of PROs with treatment response and survival, and explore tumour-related and patient-centric composite end points in patients with cancer participating in clinical trials.

Phylogenomic analysis of 7,923 angiosperm species using a standardized set of 353 nuclear genes produced an angiosperm tree of life dated with 200 fossil calibrations, providing key insights into evolutionary relationships and diversification.

A family of host-derived bile acid–methylcysteamine conjugates functions as FXR antagonists, forming part of a microbiota-dependent metabolic network that regulates FXR-dependent physiology.

Localized rectal adenocarcinoma responds well to 5-fluorouracil/radiation-based therapy. Willett et al. present the case of a 55-year-old woman who was diagnosed with extensive and locally invasive carcinoma of the rectum and received bevacizumab in combination with chemoradiotherapy. Upon completion of neoadjuvant therapy, the patient underwent abdominoperineal resection with posterior vaginectomy, hysterectomy and bilateral salpingo-oophorectomy. The authors discuss the complete response seen in this patient and insights into the application and clinical management of using anti-VEGF therapy with chemoradiation.

Lean body mass is a highly heritable trait and is associated with various health conditions. Here, Kiel and colleagues perform a meta-analysis of genome-wide association studies for whole body lean body mass and find five novel genetic loci to be significantly associated.

Using data from a single time point, passenger-approximated clonal expansion rate (PACER) estimates the fitness of common driver mutations that lead to clonal haematopoiesis and identifies TCL1A activation as a mediator of clonal expansion.

The exoplanet HD 189733b has a metal-enriched atmosphere with the possible presence of H₂O (13.4σ), CO₂ (11.2σ), CO (5σ) and H₂S (4.5σ).

Haematopoietic stem and progenitor cells (HSPCs) are found in unique bone marrow microenvironments. Silberstein and colleagues use imaging cytometry to quantitatively determine HSPC distribution in femoral bones. They find that HSPCs are in endosteal zones, in close proximity to specialized microvessels, and that they appear in a hypoxic state whether or not they are close to the vasculature.

β-cell dysfunction in diabetes is caused by glucose and inflammation toxicity. Here, Fu et al. show that β-cell glucose metabolism can be protective though pyruvate carboxylase–mediated shunting of arginine to ureagenesis and away from toxic nitric oxide production, thus suppressing inflammation.

It is notoriously difficult to target transcription factors with aberrant activity in cancer. Inappropriate activation of the NOTCH complex of transcription factors is directly implicated in the pathogenesis of several disease states, including T-cell acute lymphoblastic leukaemia. The design of synthetic, cell-permeable, stabilized α-helical peptides that disrupt protein–protein interactions in NOTCH is now described.
