We describe a new release of the PeptideAtlas proteomics spectral resource (build 2024-03), providing a sequence coverage of 79.5% at the canonical protein level, matched mass spectrometry spectra, and experimental evidence identifying 3382 and 536 phosphorylated serine and threonine sites with false localization rates of 1% and 5.3%, respectively. We provide a tutorial on how to use the PeptideAtlas and associated tools to access this information. The PeptideAtlas summary web page provides "Build overview", "PTM coverage", "Experiment contribution", and "Dataset contribution" information. The protein and peptide information can also be accessed via the Genome Database via hyperlinks on each protein page. This allows users to peruse identified peptides, protein coverage, post-translational modifications (PTMs), and experiments identifying each protein. Given the value of understanding the PTM landscape in the sequence of each protein, a more detailed explanation of how to interpret and analyse PTM results is provided in the PeptideAtlas of this important pathogen.

The exploration of the mitochondrial apoptotic pathway in living cells is of great significance for achieving tumor diagnosis and treatment. However, visualization of the mitochondrial apoptotic pathway induced by specific proteins has rarely been reported. In this paper, we designed and synthesized a fluorescent probe Cy-JQ1 based on the bromodomain-containing protein 4 (BRD4) inhibition.

Glioblastoma (GBM) is a malignant tumor with highly heterogeneous and invasive characteristics leading to a poor prognosis. The CD44 molecule, which is highly expressed in GBM, has emerged as a highly sought-after biological marker. Therapeutic strategies targeting the cell membrane protein CD44 have emerged, demonstrating novel therapeutic potential.

Silk fibroin (SF) hydrogels are widely used in three-dimensional (3D) cell culture and tissue repair. Despite their importance, few studies have focused on regulating their degradation and further revealing the effects of the degradation process on encapsulated cell behaviors. Herein, SF hydrogels with equivalent initial properties and different degradation rates were prepared by adjusting the ratios between the hydrogel-encapsulated normal SF microspheres (MS) and enzyme-loaded SF microspheres (MS).

Objective: Trichomoniasis is a globally prevalent sexually transmitted infection caused by the protozoan Trichomonas vaginalis. Polymerase chain reaction (PCR) is the gold standard for diagnosing trichomoniasis, but it is expensive. Antigen tests are immunochromatographic immunoassays that detect T.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.
