Lipid role in synapse and nuclear envelope-associated endocytic pathways in Tauopathy.

Lipids play an essential role in synaptic function, significantly impacting synaptic physiology through their dynamic nature and signaling capabilities. Membrane lipids, including cholesterol, phospholipids, and gangliosides, are crucial for synaptic organization and function. They act as structural integrators and signaling molecules, guiding vesicle intracellular movement and regulating enzyme activity to support neuronal activity.

Nuclear transport protein suppresses Tau neurodegeneration.

The nuclear pore complex, a large multimeric structure consists of numerous protein components, serves as a crucial gatekeeper for the transport of macromolecules across the nuclear envelope in eukaryotic cells. Dysfunction of the NPC has been implicated in various neurodegenerative diseases, including Alzheimer's disease. In AD, Tau aggregates interact with NPC proteins, known as nucleoporins, leading to disruptions in nuclear transport.

Histone deacetylase's regulates Tau function in Alzheimer's disease.

Alzheimer's disease (AD) is a prevalent neurodegenerative disease associated with dementia and neuronal impairments in brain. AD is characterized histopathologically by two hallmark lesions: abnormally phosphorylated Tau inside neurons as intracellular NFTs and extracellular accumulation of amyloid β peptide (Aβ). Furthermore, it is unable to clarify the distinction between the brief association between the development and build-up of Aβ and the commencement of illness.

Nuclear Tau accumulation in Alzheimer's disease.

Tau is a well-known microtubule-associated protein and is located in the cytoplasm of neurons, which play a crucial role in Alzheimer's diseases. Due to its preferred binding to DNA sequences found in the nucleolus and pericentromeric heterochromatin, Tau has been found within the cell nucleus, where it may be a nucleic acid-associated protein. Tau has the ability to directly interact with nuclear pore complex nucleoporins, influencing both their structural and functional integrity.

Semisynthesis of Alkaloid Derivatives: Pyranoacridone-Hydroxamic Acid Cytotoxic Conjugates with HDAC and Topoisomerase II α Dual Inhibitory Activity.

Inspired by our previous efforts in the semisynthetic modification of naturally occurring pyranoacridones, we report the targeted design and semisynthesis of dual inhibitors of HDAC and topoisomerase II α (Topo II α) derived from des--methylacronycine () and noracronycine () pyranoacridone alkaloids. Designed from the clinically approved SAHA, the cytotoxic pyranoacridone nuclei from the alkaloids served as the capping group, while a hydroxamic acid moiety functioned as the zinc-binding group. Out of 16 compounds evaluated in an cytotoxicity assay, KT32 () with noracronycine () as the capping group and five-carbon linker hydroxamic acid side chains showed good cytotoxic activity with IC values of 1.

A Comprehensive Review on Preparation of Silver Nanoparticles from a Bacteriocin for the Natural Preservation of Food Products.

Food preservation aims to maintain safe and nutritious food for extended periods by inhibiting microbial growth that causes spoilage and poses health risks. Traditional chemical preservatives like sodium sulfite, sodium nitrite, sodium benzoate, tBHQ and BHA have raised concerns due to potential carcinogenicity, genotoxicity and allergies with long-term consumption. As a natural alternative, bacteriocins have emerged for food preservation.

Dysregulation of protein degradation and alteration of secretome in α-synuclein-exposed astrocytes: implications for dopaminergic neuronal dysfunction.

Background: A key factor in the propagation of α-synuclein pathology is the compromised protein quality control system. Variations in membrane association and astrocytic uptake between different α-synuclein forms suggest differences in exocytosis or membrane cleavage, potentially impacting the secretome's influence on dopaminergic neurons. We aimed to understand differences in protein degradation mechanisms of astrocytes for both wild-type (WT) and mutant forms of α-synuclein, specifically during periods of reduced degradation efficiency.
