TDP-43 nuclear retention is antagonized by hypo-phosphorylation of its C-terminus in the cytoplasm.

Protein aggregation is a hallmark of many neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), in which TDP-43, a nuclear RNA-binding protein, forms cytoplasmic inclusions. Here, we have developed a robust and automated method to assess protein self-assembly in the cytoplasm using microtubules as nanoplatforms. Importantly, we have analyzed specifically the self-assembly of full-length TDP-43 and its mRNA binding that are regulated by the phosphorylation of its self-adhesive C-terminus, which is the recipient of many pathological mutations.

In silico analysis of novel Triacontafluoropentadec-1-ene as a sustainable replacement for dodecane in fisheries microplastics: Molecular docking, dynamics simulation and pharmacophore studies of acetylcholinesterase activity.

Plastics play an essential role in modern fisheries and their degradation releases micro- and nano-sized plastic particles which further causes ecological and human health hazards through various environmental contamination pathways and toxicity mechanisms, which can cause respiratory problems, cancer, reproductive toxicity, endocrine disruption and neurological effects in humans. This study utilized various bioinformatics tools through multi-step computational analyses to investigate the interactions between prevalent fisheries microplastics and the key protein receptor acetylcholinesterase (AChE), which is associated with neurotoxicity, as it can interfere with nerve impulses and muscle control. Our results indicate that the binding of seven polymers within AChE's active site, with dodecane and polypropylene exhibited highest affinity with hydrogen bonding were observed through Molecular docking of different program (PyRx) and servers (CB-Dock, eDock) then the stability of AChE-dodecane and AChE-polypropylene complexes were observed through MD simulations for 100 ns.

Factors Affecting Growth and Survival of in Onion Extracts and Onion Bulbs.

This study investigated the survival and growth of in onion extracts and bulbs. The inhibition or retardation of growth by extracts of red, white, and yellow onions was tested against the onion germplasm and exposure to different light spectra during curing. Separately, survival of Newport was tested on red, white, and yellow onion bulbs on the external and internal onion layers with a syringe and needle.

Induction of MASH in three-dimensional bioprinted human liver tissue.

Metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (MASH), is a major risk factor for cirrhosis and hepatocellular carcinoma (HCC) and a leading cause of liver transplantation. MASH is caused by an accumulation of toxic fat molecules in the hepatocyte which leads to inflammation and fibrosis. Inadequate human "MASH in a dish" models have limited our advances in understanding MASH pathogenesis and in drug discovery.

Proteasome Activators and Ageing: Restoring Proteostasis Using Small Molecules.

Ageing is an inevitable phenomenon that remains under control of a plethora of signalling pathways and regulatory mechanisms. Slowing of cellular homeostasis and repair pathways, declining genomic and proteomic integrity, and deficient stress regulatory machinery may cause accumulating damage triggering initiation of pathways leading to ageing-associated changes. Multiple genetic studies in small laboratory organisms focused on the manipulation of proteasomal activities have shown promising results in delaying the age-related decline and improving the lifespan.
