Background The specific pathological findings in Alzheimer’s disease (AD) brain are senile plaques composed of amyloid-β protein (Aβ) and neurofibrillary tangles (NFTs) highly phosphorylated tau protein. It has been suggested that autophagy may play an important role the degradation proteins. In this study, we investigated whether is involved oligomeric by immunohistochemistry using autopsied A...
The process of autophagy involves the formation of autophagosomes, double-membrane structures that encapsulate cytosol. Microtubule-associated protein light chain 3 (LC3) was the first protein shown to specifically label autophagosomal membranes in mammalian cells, and subsequently EGFP-LC3 has become one of the most widely utilized reporters of autophagy. Although LC3 is currently thought to f...
C-reactive protein (CRP), was recently reported to be closely associated with poor renal function in patients with acute kidney injury (AKI), but whether CRP is pathogenic or a mere biomarker in AKI remains largely unclear. Impaired autophagy is known to exacerbate renal ischemia-reperfusion injury (IRI). We examined whether the pathogenic role of CRP in AKI is associated with reduction of auto...
During autophagy, the microtubule-associated protein light chain 3 (LC3), a specific autophagic marker in mammalian cells, is processed from the cytosolic form (LC3-I) to the membrane-bound form (LC3-II). In HEK293 cells stably expressing FLAG-tagged LC3, activation of protein kinase C inhibited the autophagic processing of LC3-I to LC3-II induced by amino acid starvation or rapamycin. PKC inhi...
UNLABELLED The enteropathogenic bacterium Shigella flexneri uses a type 3 secretion apparatus (T3SA) to transfer proteins dubbed translocators and effectors inside host cells, inducing bacterial uptake and subsequent lysis of the entry vacuole. Once in the cytoplasm, the outer membrane protein IcsA induces actin polymerization, enabling cytoplasmic movement and cell-to-cell spread of bacteria. ...
Introduction: Some factors such as exercise training and pharmacological interventions can slow tumor growth. To determine the underlying mechanisms, we investigated the effect of six weeks of interval exercise training along with ingestion on Bcl-2 and LC3 genes expression in the tumor tissue of breast tumor–bearing mice. Methods: Twelve female BALB/c mice were injected with cancer cell line a...
Autophagy is a bulk protein and organelle degradation process essential for cell maintenance and viability. Microtubule-associated protein 1 light chain 3 (LC3), the mammalian homologue of yeast Atg8, is involved in autophagosome formation during autophagy. The aim of this study was to investigate LC3 expression in gastrointestinal cancers to elucidate the role of autophagy in human cancer deve...
Rat LC3, a homologue of yeast Atg8 (Aut7/Apg8), localizes to autophagosomal membranes after post-translational modifications. The C-terminal fragment of LC3 is cleaved immediately following synthesis to yield a cytosolic form called LC3-I. A subpopulation of LC3-I is further converted to an autophagosome-associating form, LC3-II. Because yeast Atg8 is conjugated with phosphatidylethanolamine (P...
LC3 is widely used marker for macroautophagy assays. After translation pro-LC3 is processed by Atg4 to expose C-terminal glycine residue for downstream conjugation reactions to accomplish the conversion of LC3-I to LC3-II. SDS-PAGE based Western blot (Wb) is generally utilized to quantify LC3-II levels where the LC3-I band migrates slower than LC3-II. We found that pro-human LC3B migrated at si...
