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

44 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

36 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

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

384 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

601 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]

Tolbutamide is a type of medicine called a sulphonylurea

Surgery was performed using aseptic procedures. Anaesthesia was induced using ketamine, which was followed by 2 C5% isofluorane Tolbutamide mixed with oxygen administered by inhalation for the length of the surgical procedure. The skin and fascia were removed from the dorsal surface of the skull. [Read the Full Post]

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by excessive and chronic activation of inflammatory pathways via immune Tolbutamide complex deposition, complement activation, and Fc receptor (FcR) ligation, often leading to significant clinical pathologies including glomerulonephritis [Read the Full Post]
