RNA degradation by DIS3 is a necessary step in the resolution of backtracked transcription complexes

Summary The RNA exosome is known to participate in transcription, but the contribution of its ribonuclease activities to this process remains unclear. Here we investigated the role of DIS3, one of the exosome ribonucleases, in transcription by RNA polymerase II (RNAPII). Rapid de...

Structure-guided allosteric modulation of the delta opioid receptor

Abstract Opioid analgesics remain essential for pain management but are associated with significant adverse effects, including respiratory depression, tolerance, and dependence. The δ-opioid receptor (δOR) represents a promising therapeutic target for developing safer opioid anal...

High-Ratio Partial Proteolysis with Carrier Proteome (HOLSER) Enables Global Structure Profiling and Site-Resolved Elucidation of Ligand-Protein Interactions.

Understanding how cellular proteins interact with their environment, including endogenous and exogenous molecules, is critical for elucidating mechanisms of cellular regulation and drug action. Partial proteolysis-based techniques offer peptide-level resolution of ligand-induced...

Multi-omics profiling reveals gene signatures and therapeutic targets in HER2-guided gastric cardia adenocarcinoma patients

Abstract Therapeutic targets for gastric cardia adenocarcinoma (GCA), particularly for HER2-negative patients, are lacking. Here, we conducted multi-omics profiling on 128 GCA patients using mass spectrometry, whole-exome sequencing, RNA-Seq, scRNA-Seq and spatial transcriptomics...

Cell surface remodeling caused by the loss of the flippase subunit TMEM30A in immune cells

Plasma membrane lipid asymmetry is tightly regulated and fundamental to mammalian cell physiology. TMEM30A is the β-subunit of P4-ATPases, flippase enzymes that maintain strict phosphatidylserine (PS) asymmetry by pumping it from the outer to the cytosolic leaflet. Loss of TMEM30...

Genome-wide association study of image-based emphysema scoring in the Swedish CArdioPulmonary bioImage Study (SCAPIS) suggests two new risk loci in smokers

Abstract Background Despite the high prevalence and clinical significance of emphysema, few genetic risk loci have been consistently replicated. We conducted a genome-wide association study (GWAS) of CT-based emphysema, with a particular focus on non-smoking-related genetic deter...
