    Activity Assay:

    Article Title: SGLT2 Inhibitors Rescue Lysosomal mTORC1 Hyperactivity and Proximal Tubulopathy in Preclinical Models of Cystinosis
    Article Snippet: .. Lysosomal proteolytic activity in primary mPTCs was assessed using Bodipy-FL-Pepstatin A (P12271, Thermo Fischer Scientific), a fluorescent probe that binds active cathepsin D. Cells were incubated with 1μM BODIPY FL–Pepstatin A in Live Cell Imaging medium for 1 hour at 37°C, followed by fixation and analysis by confocal microscopy. .. Quantification of lysosomal activity was performed by measuring the number of Pepstatin A-positive structures per cell were quantified using the open-source cell image analysis software CellProfiler TM .

    Article Title: Estrogen protects against ethanol-induced astrocytic response in dorsal hippocampus but not ethanol-induced liver inflammation in ovariectomized mice.
    Article Snippet: Sex has been shown to play a dynamic role in the responses to alcohol, with women often being cited as having more detrimental consequences from alcohol use.. The current increasing rates of alcohol drinking by women, including women over 50, highlights the importance of studying the participation of sex hormones in the effects of alcohol misuse.. Alcohol is known to produce both central and peripheric inflammation, but the interaction between alcohol and estradiol is poorly understood.
