Modifications enhancing degradation resistance and albumin affinity enabled the delivery of an siRNA conjugate silencing MMP13 to guinea pig and murine arthritic joints, improving therapeutic outcomes following intravenous administration.

The OX₂ orexin receptor (OX₂R) is a brain GPCR that regulates wakefulness and circadian rhythms in humans, and a potential drug target in insomnia and narcolepsy. Here, the authors use cryo-EM to determine how the first clinically tested OX₂R agonist TAK-925 can activate OX₂R in a selective manner.

Synthetic Notch (synNotch) receptors are genetically encoded, modular synthetic receptors that enable mammalian cells to detect environmental signals and respond by activating user-prescribed transcriptional programs. Here the authors apply synNotch receptors to spatially control differentiation of endothelial and skeletal muscle cells in a multicellular construct on assorted biomaterials.

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.

Longitudinal genomic and transcriptomic profiling of 1,143 patients with multiple myeloma by the Relating Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile study yields an improved copy number and gene expression subtype scheme, most notably a high-risk proliferative subtype associated with complete loss of RB1 or MAX.

Heart failure is a major cause of cardiovascular morbidity and mortality. Here, the authors report results of a genome-wide association study meta-analysis, characterizing the role of common genetic variants in heart failure, finding overlap with common cardiovascular risk factors and imaging measures of cardiac structure/function.

A conserved gene regulatory network involving SOX4, SOX11 and TFAP2D shapes the development of excitatory neurons in ventrolateral pallium and their connectivity with the prefrontal cortex.

Exome-sequencing analyses of a large cohort of patients with type 2 diabetes and control individuals without diabetes from five ancestries are used to identify gene-level associations of rare variants that are associated with type 2 diabetes.

A genome-wide association study in more than 400,000 individuals identifies 139 new signals for lung function. These variants can predict chronic obstructive pulmonary disease in independent, transancestral cohorts.

De novo mutations in MSL3 cause an X-linked syndrome affecting both males and females. MSL3 mutations reduce H4K16ac levels and lead to misregulation of cellular pathways involved in morphogenesis, cellular shape, and cell migration.

Trans-ethnic analyses of exome array data identify new risk loci for type 2 diabetes. Fine-mapping analyses using genome-wide association data show that the index coding variants represent the likely causal variants at only a subset of these loci.

Medulloblastomas lacking p53 do not express surface class I major histocompatibility complex (MHC-I) and are resistant to immune rejection. Tumor necrosis factor rescues MHC-I expression and synergizes with immune checkpoint inhibitors to promote rejection.

By combining advanced age and laser photocoagulation, Zhu et al. establish a novel CNV model of anti-VEGF resistance. They show that lipid accumulation in old macrophages promote angiogenesis, and that apoA-I binding protein (AIBP) inhibits angiogenesis by reducing this lipid accumulation. They further show that the combination of AIBP/apoA-I and anti-VEGF treatment overcomes anti-VEGF resistance and effectively suppresses CNV.
