Article Abstract
Signal transducer and activator of transcription 3 (Stat3), a critical transcription factor, plays an essential role in cellular processes such as proliferation, development, and differentiation. It also significantly contributes to the pathogenesis of cardiovascular diseases and various cancers, including breast cancer, pancreatic cancer, and renal cell carcinoma. The functional dynamics of Stat3 are intricately regulated by post-translational modifications (PTMs) such as phosphorylation, sulfenylation, acetylation, sulfhydrylation, and SUMOylation. These modifications, triggered by pathophysiological signals, induce structural changes in Stat3 across different cell types, thereby regulating distinct gene expression programs. Such modifications can either enhance or inhibit Stat3's transcriptional activity and affect its DNA-binding stability. This review explores the various PTMs that modulate Stat3 function, offering a comprehensive analysis of the regulatory mechanisms that govern Stat3 within cellular signaling networks. The findings are expected to provide valuable insights into the development of novel therapeutic agents targeting these pathways, ultimately revealing new targets and innovative strategies for treating a range of diseases.

Zika virus (ZIKV) is a mosquito-borne flavivirus causing a major epidemic in the Americas in 2015. Dendritic cells (DCs) are leukocytes with key antiviral functions, but their role in ZIKV infection remains under investigation. While most studies have focused on the monocyte-derived subtype of DCs, less is known about conventional dendritic cells (cDCs), essential for the orchestration of antiviral adaptive immunity.

Background: As a highly invasive gastrointestinal malignancy, esophageal squamous cell carcinoma (ESCC) carries with its high morbidity and mortality. Accumulating evidence indicates that abnormal activation of ubiquitination and deubiquitylation has been implicated in pathophysiology of ESCC. However, rare prognostic models for ubiquitination-related genes (URGs) and deubiquitylation-related genes (DRGs) have been built up in ESCC.

The multi-attribute method (MAM), a mass spectrometry technique for quantifying amino acid modifications at the peptide level, is becoming a prominent analytical tool in the development of biotherapeutics. The method has promise for adeno-associated virus (AAV) therapeutics, where capsid protein modifications have been directly linked to reduced transduction efficiency. Given this link, a robust and precise procedure to quantitate capsid modifications would be beneficial for implementation throughout biotherapeutic development.

Motivation: Lysine (K) succinylation is a crucial post-translational modification involved in cellular homeostasis and metabolism, and has been linked to several diseases in recent research. Despite its emerging importance, current computational methods are limited in performance for predicting succinylation sites.
Results: We propose ResLysEmbed, a novel ResNet-based architecture that combines traditional word embeddings with per-residue embeddings from protein language models for succinylation site prediction.
Acetylation Mimetic and Null Mutations Within the Filament Core of P301L Tau Have Varied Effects on Susceptibility to Seeding and Aggregation.

The two most prominent post-translational modifications of pathologic tau are Ser/Thr/Tyr phosphorylation and Lys acetylation. Whether acetylation impacts the susceptibility of tau to templated seeding in diseases like Alzheimer's disease (AD) and Progressive Supranuclear Palsy (PSP) is largely uncharacterized. Towards this, we examined how acetylation mimicking or nullifying mutations on five sites of tau (K311, K353, K369, K370, K375), located within the tau filament core, influenced the susceptibility of P301L (PL) tau to seeds from AD (AD-tau) or PSP (PSP-tau) brain donors in HEK293T cells.
