LAMP2-regulates-autophagy-in-the-thymic-epithelium-and-thymic-stroma-dependent-CD4-T-cell-development

182 views | May 31 2022

Pedro M Rodrigues et al. suggested that LAMP2 interconnected the autophagy-lysosomal axis and the processing of selecting self-peptides:MHC II complexes in cTECs, underling its implications for the generation of a broad CD4 TCR repertoire. [Read the Full Post]

The role of autophagy in cadmium-induced acute toxicity in glomerular mesangial cells and tracking polyubiquitination of cytoplasmic p53 as a biomarker

184 views | May 30 2022

Ki-Tae Jung et al. indicated that cytoplasmic polyUb-p53 was a potential biomarker for Cd-induced acute toxicity in mesangial cells. [Read the Full Post]

Detection of autophagic flux in primary cerebral cortical neurons after oxygen glucose deprivation/reperfusion (OGD/R) using various methods

Lei Zhang et al. showed that different methods and indicators could be used to monitor different stages of autophagy. [Read the Full Post]

Berberine Represses Human Gastric Cancer Cell Growth in Vitro and in Vivo by Inducing Cytostatic Autophagy via Inhibition of MAPK/mTOR/p70S6K and Akt Signaling Pathways

495 views | Jun 04 2020

Qiang Zhang et al. indicated that berberine repressed human gastric cancer cell growth in vitro and in vivo by inducing cytostatic autophagy via inhibition of MAPK/mTOR/p70S6K and Akt, and provided a molecular basis for the treatment of gastric cancer. [Read the Full Post]

HMGB1-induced Aberrant Autophagy Contributes to Insulin Resistance in Granulosa Cells in PCOS

522 views | Jun 04 2020

Chuyue Zhang et al. indicated that increased HMGB1 contributes to IR development in granulosa cells of PCOS patients, which was associated with exacerbation of autophagy by HMGB1. Control of HMGB1 production might be benefical for the improvement of insulin sensitivity in granulosa cells in PCOS. [Read the Full Post]

Bafilomycin A1 disrupts autophagic flux by inhibiting both V-ATPase-dependent acidification and Ca-P60A/SERCA-dependent autophagosome-lysosome fusion

467 views | Sep 07 2019

Mauvezin C et al. identified the ER-calcium ATPase Ca-P60A/dSERCA as a novel target of bafilomycin A1. Autophagosome-lysosome fusion was defective in Ca-P60A/dSERCA-depleted cells, and bafilomycin A1 induced a significant increase in cytosolic calcium concentration and disrupted Ca-P60A/SERCA-mediated fusion. Thus, bafilomycin A1 disrupts autophagic flux by independently inhibiting V-ATPase-dependent acidification and Ca-P60A/SERCA-dependent autophagosome-lysosome fusion. [Read the Full Post]

Bafilomycin A1 triggers proliferative potential of senescent cancer cells in vitro and in NOD/SCID mice

525 views | Aug 01 2019

Was H et al. suggested that senescent cancer cells that appear during therapy, can be considered as dormant cells that contribute to cancer re-growth, when chemotherapeutic treatment is stopped. These data unveil new mechanisms of TIS-related cancer maintenance and re-population, triggered by a single pulse of BAF A1 treatment. [Read the Full Post]

Autophagy Plays an Important Role in Anti-inflammatory Mechanisms Stimulated by Alpha7 Nicotinic Acetylcholine Receptor

646 views | Nov 23 2018

Shao BZ et al. demonstrated for the first time that activating α7nAChR enhances monocyte/microglia autophagy, which suppresses neuroinflammation and thus plays an alleviative role in EAE. [Read the Full Post]

Acute hyperglycemia suppresses left ventricular diastolic function and inhibits autophagic flux in mice under prohypertrophic stimulation

816 views | Jul 28 2018

Xie J et al. found that acute hyperglycemia suppresses diastolic function, damages mitochondrial energy signaling, and inhibits autophagic flux in prohypertrophic factor-stimulated cardiomyocytes. [Read the Full Post]

Weak binding to E3 ubiquitin ligase c-Cbl increases EGFRvA protein stability

1094 views | Dec 04 2017

Song F et al. found that EGFRvA is more stable than EGFR because of its decreased binding to c-Cbl. [Read the Full Post]
