Natural polyamines, such as spermidine and spermine, exert strong anti-inflammatory effects, but their therapeutic benefits are limited by rapid absorption in the small intestine, resulting in low colonic availability. In this study, engineered Citrobacter freundii overexpressing ppk1 (CPP) coul...

Cells have evolved multiple strategies to survive environmental stress conditions. This includes the formation of membrane-less cytoplasmic ribonucleoprotein structures called stress granules that sequester and protect mRNAs encoding many housekeeping genes. Stress granules are not static biomolecul...

RNA localization to stress granules

Cancer cells can always be unexpected rescued from desperate environment by mounting adaptive responses to resolve the arising cellular stress. The dynamic stress granules (SGs) assembly and metabolic reprogramming play crucial roles in maintaining cellular growth and homeostasis. However, the me...

Stress granules are small RNA-protein granules that modify the translational landscape during cellular stress to promote survival. The RhoGTPase RhoA is implicated in the formation of RNA stress granules. Our data demonstrate that the cytokinetic proteins ECT2 and AurkB are localized to stress gran...

The stress granule transcriptome reveals principles of mRNA accumulation in stress granules.
Stress granules (SGs) and processing bodies (PBs) are membraneless cytoplasmic assemblies regulating mRNAs under environmental stress such as viral infections, neurological disorders, or cancer. Upon antigen stimulation, T lymphocytes mediate their immune functions under regulatory mechanisms involv...

Stress Granule formation has been linked to the resistance of some cancer cells to chemotherapeutic intervention. A number of studies have proposed that certain anti-tumor compounds promote cancer cell survival by inducing Stress Granules formation, leading to increased cellular fitness and apoptosi...

Stress Granules (SG) formation is a cellular protection mechanism, constituting a storage for untranslated mRNAs and RNA-binding proteins (RBPs); however, these condensates can turn into pathological aggregates, related to the onset of neurodegenerative diseases like Amyotrophic Lateral Sclerosis (A...

Neuromelanin is a black-brownish pigment, present in so-called neuromelanin granules (NMGs) in the cell bodies of dopaminergic neurons in the substantia nigra (SN) pars compacta. These neurons are lost in neurodegenerative diseases like Parkinson’s disease and dementia with Lewy bodies. Although it ...
