The rapidly developing search engines for glycopeptide identification and accumulated high-resolution glycoproteomic data underscore the need for robust downstream data mining platforms towards subsequently functional and mechanistic studies. Here, we introduce StrucGAP, a Structural Glycoproteomics Analysis Platform for scalable downstream data mining of site-specific N-glycoproteomics. It integrates modules for data quality control, overall glycan structural characterization, altered glycan...

We identified a new progeroid syndrome with severe neuropathy and intellectual deficits but its underlying cellular and molecular mechanism is unknown. Exome sequencing revealed a homozygous mutation in the IVNS1ABP gene, which encodes IVNS1ABP, an influenza virus non-structural protein-1 binding protein. To investigate disease mechanisms, we generated isogenic induced pluripotent stem cells (iPSCs) from patient fibroblasts and differentiated them into neural progenitor cells (NPCs). Mutant...

The global challenge of population aging underscores the critical need to delay brain aging and cognitive decline, a pressing public health issue. The brain-gut-muscle axis is a complex regulatory network connecting skeletal muscle, gut microbiota, and the brain. It has received considerable research attention for its crucial role in maintaining brain health and counteracting aging. As a safe and effective non-pharmacological intervention, exercise modulates gut microbiota composition and...

INTRODUCTION: TAS2R38 is a taste receptor gene located on human chromosome 7 that influences sensitivity to bitter tastes and has been implicated in innate immunity, glucose level, and human longevity. However, its potential association with Alzheimer's Disease (AD) has not been explored. Identifying such a genetic connection could support developing new drugs or repurposing existing ones for AD treatment.

The gut microbiome influences brain function through the gut-brain axis via synthesis of neurotransmitters, production of metabolites affecting epithelial barrier integrity and immune modulation and signaling through the vagus nerve. In humans, microbiome diversity reflects healthy aging and predicts survival, while dysbiosis is increasingly implicated in neurodegenerative conditions including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ALS. Fecal transplant studies in...

CONCLUSION: Age-related changes in balance control are task dependent. Older adults preserved static balance performance but demonstrated impaired reactive balance responses in dynamic tasks. Furthermore, static and dynamic balance rely on distinct control mechanisms, highlighting the need for separate assessments.

GDF15, which is thought to contribute to nausea during pregnancy, may keep our drinking in check, researchers propose
