Check if the same lab product or an alternative is used in the 5 most similar protocols
Conditionally immortalized podocytes MPC-5 were kindly provided by Professor Peter Mundel (Albert Einstein College of Medicine, New York, NY, USA) and cultured as previously reported in the literature [15] .
All experiments were performed with differentiated podocytes, free of mycoplasma infection. HG culture medium was made by supplementing normal glucose RPMI 1640 medium (Thermo Gibco, Waltham, MA, USA) containing 5.5 mmol/l D-glucose with additional D-glucose (Sinopharm, Shanghai, China) for a nal D-glucose concentration at 30 mmol/l. Podocytes cultured in normal or high glucose were stimulated with or without 25 ng/ml HGF in the absence or presence of 2.5 μmol/l SU11274 (S1080, Selleck, Houston, TX, USA) for 24 h. SU11274 was added 1 h before HGF supplementation. After treatment, podocytes grown on 60mm culture dishes (Corning, New York, NY, USA) were harvested and the lysate measurement and western blotting were the same as above.

Propofol Mitigates Glucose-Induced Stress in H9c2 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
H9c2 cells were acquired from the Chinese Academy of Science, Shanghai Cell Bank and cultured in low glucose (5.5 mM) minimum essential medium (Gibco-Invitrogen, Grand Island, NY, USA) complemented with 10% heat-inactivated fetal bovine serum (FBS; Gibco BRL, Grand Island, NY, USA), 100 U/mL of penicillin, and 50 g/mL of streptomycin (Beyotime Institute of Biotechnology, China). The cells were placed in a humidified atmosphere containing 5% CO2 at 37 °C.
To establish a high glucose- (HG-) induced stress model in H9c2 cells, D-glucose (Sinopharm Chemical Reagent Co. Ltd., Shanghai, China) was added in culture medium to reach the final concentration of 22 mM glucose. The concentration of 5.5 mM glucose was used as the control group. A dose-dependent effect of propofol was evaluated by adding 5, 10, 20, and 40 µM of propofol to the cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
