HNF1B is overexpressed in the clear cell subtype and epigenetically silenced in the serous subtype of ovarian cancer. Pearce and colleagues now show that genetic variants in HNF1B are differentially associated with risks of developing these two cancer subtypes, possibly through an epigenetic mechanism.

In people with HIV-1 undergoing antiretroviral treatment interruption, lefitolimod combined with broadly neutralizing antibodies (bNAbs) did not delay viral rebound beyond that achieved with bNAbs alone, raising the question of how to optimize combination immunotherapy to control HIV-1.

The PSA (KLK3) genetic variant rs17632542 is associated with reduced prostate cancer risk and lower serum PSA levels, although the underlying reasons are unclear. Here, the authors show that this PSA variant reduced proteolytic activity and leads to smaller tumours, but also increases invasion and bone metastasis, indicating its dual risk association depending on tumour context; the variant is associated with both lower risk and poor clinical outcomes.

Most confirmed susceptibility variants for epithelial ovarian cancer lie in non-protein-coding sequences. Here Permuth-Wey and colleagues investigate variants in 3′ untranslated regions (UTRs) and uncover a new susceptibility locus.

Paul Pharoah, Joellen Schildkraut, Thomas Sellers and colleagues report a meta-analysis of genome-wide association studies for epithelial ovarian cancer and genotyping using the iCOGS array in 18,174 cases and 26,134 controls from 43 studies from the Ovarian Cancer Association Consortium. They identify three new ovarian cancer susceptibility loci, including one specific to the serous subtype, and their integrated molecular analysis of genes and regulatory regions at these loci suggests disease mechanisms.

Stig Bojesen, Georgia Chenevix-Trench, Alison Dunning and colleagues report common variants at the TERT-CLPTM1L locus associated with mean telomere length measured in whole blood. They also identify associations at this locus to breast or ovarian cancer susceptibility and report functional studies in breast and ovarian cancer tissue and cell lines.

Dense water that formed over the Antarctic continental shelf spreads throughout the global ocean as Antarctic Bottom Water. Observations over eight years reveal a strong seasonal cycle in the flow of Weddell Sea bottom water northwards that is linked to winds over the western margin of the Weddell Sea.

In some HIV-1-infected individuals, viraemia remains undetectable after antiretroviral treatment, but which of these patients will experience viral rebound is difficult to predict. Here the authors show that T cell exhaustion markers before treatment are predictive of shorter time to viral rebound.

The authors link the effects of pCO₂ on marine invertebrates to the localized pCO₂ conditions of their coastal habitats. They show that responses depend on the deviation from the locally experienced upper pCO₂ level, highlighting the importance of small-scale variability and adaptation.

Genome-wide association meta-analyses identify 26 risk loci for epilepsy, including 19 loci specific to genetic generalized epilepsy. Prioritized candidate genes implicate synaptic processes and overlap with targets of antiseizure medications.

Cortex morphology varies with age, cognitive function, and in neurological and psychiatric diseases. Here the authors report 160 genome-wide significant associations with thickness, surface area and volume of the total cortex and 34 cortical regions from a GWAS meta-analysis in 22,824 adults.

Monoclonal antibodies (mAbs) have shown efficacy against SARS-CoV-2 infection in clinical trials. Here the authors model the dose-response relationship between the dose of mAbs and protection from symptomatic SARS-CoV-2 infection. Further, the protection is comparable to that achieved by vaccination.

Here a meta-analysis identifies an additional nine novel endometrial cancer risk loci and eQTL analysis reveals risk variants associate with reduced expression of negative regulators of oncogenic signal transduction proteins.

An inhibitor of the deubiquitinase (DUB) USP10 regulates the degradation of oncogenic FLT3, thus defining USP10 as a DUB for FLT3 and providing a therapeutic approach for human acute myeloid leukemia in which FLT3 activation is dysregulated.

FLS2 is the well-known plasma membrane receptor for flg22, a specific region of bacterial flagellin. But Solanaceae can also detect flagellin through another epitope, flgII-28, thanks to the novel receptor-like kinase FLS3 now identified in tomato.

The atmosphere has dried across most regions of Europe in recent decades, a trend that can be attributed primarily to human impacts, according to tree ring records spanning 400 years and Earth system model simulations.

Exhausted T cells arise when chronic activation triggers functional defects. Here the authors show that chronic antigenic stimulation in both tumour and infection models induces the expression of EGR2, which drives and stabilises exhausted cell epigenetic and transcriptional identity.

BATF3 is a member of the AP-1 transcription factor family. Kastenmüller and colleagues show that BATF3 is needed to promote memory CD8⁺ T cell responses. Activated CD8⁺ T cells transiently upregulate BATF3, which in turn suppresses expression of proapoptotic BIM to promote cell survival.

Late Pliocene cooling led to the glaciation of the Northern Hemisphere, yet its trigger remains unclear. Here, the authors present neodymium and lead isotope records from the Bering Sea, and propose that the introduction of low-salinity water into the Arctic Ocean preconditioned Pliocene cooling.

Treatment of HIV-1 infected patients with latency-reversing agents (LRA) induces transcription of proviruses in CD4 T cells. Using single-genome sequencing, the authors show that the LRA-induced CD4 T cell-associated HIV RNA is genetically diverse and contains a high proportion of defective RNA.
