Check if the same lab product or an alternative is used in the 5 most similar protocols
Parental KP cells (0.5×106) were injected (s.c.) into the right flank of mice. For pharmacological inhibition of MGL, tumor-bearing C57BL/6J wild-type mice were intraperitoneally (i.p.) treated with 16 mg/kg JZL184 (MGL inhibitor, Cayman), once daily, starting one day prior to the injection of tumor cells. For the experiments with MGL-overexpressing cells, either 0.5 × 106 KP _MGL or KP _ctrl cells were injected (s.c.) into the right flank of C57BL/6J wild-type mice. Tumor growth was monitored during the course of the experiments twice per week using a caliper. Mice were sacrificed after about two weeks, and tumors were subsequently collected, weighted, and measured with a caliper ex vivo. Tumor volume was calculated according to the following formula: v = length x width x height x π/6.40 (link)

Measuring ATGL and HSL Activities

Check if the same lab product or an alternative is used in the 5 most similar protocols
To determine the TG hydrolase activity of ATGL in tissue samples or cells, HSL activity can be inhibited by specific inhibitors such as NNC0076-0000-0079 (N-methyl-phenyl carbamoyl triazole, Novo Nordisk, Denmark) (Ebdrup, Sørensen, Olsen, & Jacobsen, 2004 (link); Schweiger et al., 2006 (link)) or 4-isopropyl-3-methyl-2-{1-[3-(S)-methyl-piperidin-1-yl]-methanoyl}-2H-isoxazol-5-1 (BAY; Lowe et al., 2004 (link)). Alternatively, murine ATGL can be specifically inhibited by Atglistatin (3-(4′-(Dimethylamino)-[1,1′-biphenyl]-3-yl)-N,N-dimethylurea) (Mayer et al., 2013 ). To determine MGL-independent MG hydrolase activity, the MGL-specific inhibitor JZL 184 (Cayman Chemicals, Michigan, United States, cat. no. 13158) can be used (Long, Nomura, & Cravatt, 2009 (link)). Stock solution (20 mM) of respective inhibitors is prepared in DMSO and stored at −80 °C. The inhibitors will be added to the samples prior to the addition of substrate. Full inhibition of ATGL, HSL, and MGL activity is obtained at 50 μM, 10 μM, and 100 nM, respectively. Rates obtained in the presence of inhibitors as compared to that in the absence will give a good approximation for ATGL and HSL activity, respectively.

The MAGL inhibitor JZL184 and the NSAID diclofenac sodium salt were purchased from Cayman Chemical (Ann Arbor, MI). The gastric acid secretagogue pentagastrin and the proton pump inhibitor omeprazole were purchased from Sigma Aldrich (St. Louis, MO). All compounds were dissolved in a vehicle consisting of ethanol, Cremophor (Sigma-Aldrich), and saline in a ratio of 1:1:18 parts, as described previously (Crowe et al., 2015 (link); Kinsey and Cole, 2013 (link)). All solutions were warmed to room temperature and administered per oral (p.o.), intraperitoneally (i.p.), or subcutaneously (s.c.) at a volume of 10 μl/g body mass. Diclofenac was administered p.o., consistent with clinical use in that the NSAID comes into direct contact with the lining of the stomach. omeprazole and JZL184 were administered i.p., and pentagastrin was administered s.c.

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.
