Raphael Bueno, Eric Stawiski, Somasekar Seshagiri and colleagues present a comprehensive genomic analysis of malignant pleural mesothelioma. They identify four distinct molecular subtypes using RNA-seq data and highlight recurrent somatic mutations, gene fusions and splicing alterations.

Gallbladder cancer incidence shows characteristic geographic patterns. Here the authors perform a genomic analysis of gallbladder cancers in patients from countries with high incidence (South Korea, India and Chile) and identify ELF3 and other significantly mutated genes not previously associated with gallbladder cancer.

South Asia is home to almost 2 billion people but is extremely underrepresented in human genetics. This study uses genomes from ~5,000 South Asians to characterize genetic variation and help facilitate future South Asian genetic studies.

Suryamohan, Diwanji, Stawiski et al. identify natural ACE2 variants that are predicted to alter virus–host interactions. They find that soluble ACE2 K26R and T92I variants are more effective in blocking the entry of SARS-CoV-2 S-protein pseudotyped virus, compared to wild-type ACE2. This study suggests that ACE2 variants may modulate the host susceptibility to SARS-CoV-2.

Somasekar Seshagiri, James Brugarolas and colleagues report the mutational landscape of 167 non–clear cell renal cell carcinomas (nccRCCs) from multiple subtypes. They identify subtype-specific driver mutations and gene fusions, including ones involving MITF, which result in expression of the anti-apoptotic protein BIRC7 and might thus indicate candidates for treatment with BIRC7 inhibitors.

Sebastian Bonhoeffer, Christos Petropoulos and colleagues report a systems analysis of the fitness landscape of HIV-1 protease and reverse transcriptase. They use a dataset of over 70,000 virus samples, isolated from HIV-1 subtype B infected individuals, assayed for in vitro replicative capacity alone or under drug selection.

Using whole-genome sequencing data from 1,739 individuals, the GenomeAsia 100K Project catalogues genetic variation, population structure and disease associations to facilitate genetic studies in Asian populations and increase representation in genetics studies worldwide.

The genetic basis of gastric cancer, the fourth most common cancer worldwide, remains poorly understood. Here, the authors sequence and analyse the exomes and transcriptomes of primary gastric tumours and cell lines, and identify a ZAK kinase isoform that may have an oncogenic role in gastric cancer.

Papillary thyroid cancer (PTC) is one of the most common type of endocrine malignancy. Here, the authors use proteogenomic approaches to analyse the primary tumour and lymph node metastases from a PTC patient and report an oncogenic RET fusion, and potential druggable targets from the ubiquitin signaling machinery for treating human PTCs.

How resistance to different classes of AKT inhibitors can emerge is unclear. Here, the authors show that resistance to allosteric inhibitors is mainly due to mutation of AKT1 while the ATP competitive resistance is driven by activation of PIM kinases in prostate cancer models.

Analysis of a near-chromosomal genome assembly and transcriptome profiling of the Indian cobra identifies genes expressed in the venom glands. These data should help develop a new antivenom.

A first-in-human phase I clinical trial demonstrates the feasibility and safety of non-viral precision genome-engineering of a personalized adoptive cell transfer anticancer therapeutic.

Sekar Seshagiri and colleagues report exome, transcriptome and copy-number alteration data in small-cell lung cancer. The authors find SOX2 amplification in 27% of samples and also identify a recurrent RFL-MYCL1 fusion.

Exomes, transcriptomes and copy-number alterations in a sample of more than 70 primary human colonic tumours were analysed in an attempt to characterize the genomic landscape; in addition to finding alterations in genes associated with commonly mutated signalling pathways, recurrent gene fusions involving R-spondin family members were also found to occur in approximately 10% of colonic tumours, revealing a potential new therapeutic target.

Aberrant expression and activity of G proteins and G-protein-coupled receptors (GPCRs) are frequently associated with tumorigenesis. Recent deep sequencing studies have shown that nearly 20% of human tumours harbour mutations in GPCRs. This Analysis article reviews these findings and the indications that G proteins, GPCRs and their signalling pathways represent novel therapeutic targets for cancer prevention and treatment.

Antibody-mediated inhibition of R-spondin-3 in colorectal tumours decreases tumour growth and promotes differentiation—these effects are associated with a decrease in expression of genes associated with stem-cell function.

A comprehensive analysis of RNA sequencing and single-nucleotide polymorphism (SNP) array data provides new insights into the biology of 675 human cancer cell lines
