Check if the same lab product or an alternative is used in the 5 most similar protocols
To create MED19-AKO mice, we obtained mice with conditional-potential allele of MED19 (MED19tm1a(EUCOMM)Wtsi from the EUCOMM repository and crossed them with actin-Flp transgenic mice to remove the targeting cassette and then subsequently crossed the mice with adiponectin-Cre mice obtained from the Jackson Laboratory (028020) to generate adipose-specific MED19 knockout (MED19-AKO) mice. To generate adipose-specific, tamoxifen-inducible MED19 KO (MED19-iAKO) mice, MED19 floxed animals were crossed with Adiponectin-CreER mice obtained from the Jackson Laboratory (025124). To induce knockout, 12-week-od control (MED19Lox/Lox without Cre) and MED19-iAKO mice were treated daily with tamoxifen (100 μg/g body weight) for five consecutive days. All experiments used male mice unless otherwise stated. All mice were kept on a 12h light/dark cycle and provided ad libitum access to food (Purina 5053) and water. All animal experiments were performed in accordance with procedures approved by the Institutional Animal Care and Use Committee at Washington University School of Medicine.

Male FGF21KO mice generated by Department of Genetic Biochemistry, Kyoto University40 (link) and WT littermates with the same genetic background were used for this study. Klb AdipoKO mice were generated by crossing the βklotho gene floxed mice (Shanghai Nanfang Centre for Model Organisms) with adiponectin-Cre mice (The Jackson Laboratory, stock No. 010803). FGF21 AdipoKO mice were generated by crossing the FGF21 gene floxed mice (Shanghai Nanfang Centre for Model Organisms) with aP2-Cre mice (The Jackson Laboratory, stock No. 005069)60 (link). Both Klb AdipoKO and FGF21 AdipoKO mice were back-crossed with C57BL/6 J background for at least eight generations to ensure the genetic homogeneity. Klb AdipoKO and FGF21 AdipoKO mice were confirmed by genotyping and western blot analysis (Supplementary Fig. 10). No randomization of mice was used. These mice were fed with either STC or HFD (Research Diet, containing 45% fat, 20% protein, and 35% carbohydrate [kcal%]). All animals were kept under 12 h light-dark cycles at 22–24 °C, 60–70% humidity with free access to water. The sample sizes of animal experiments were estimated according to previous studies and the known variability of the assays. All animal experimental protocols were approved by the Animal Ethics Committee of the University of Hong Kong.

Flox HO-1 and Adipose-Specific Knockout Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experimental procedures and protocols of this study conform to the National Institutes of Health Guide for the Care and Use of Laboratory Animals and were approved by the Institutional Animal Care and Use Committee of the University of Mississippi Medical Center (protocol 1283, initial approval 2/2014, reapproved 1/2017).
Studies were performed on male and female Flox HO-1 and adipose-specific HO-1 knockout mice. Flox HO-1 mice are designed to delete exons 3–5 and activate red fluorescent protein (dsRed) upon cre-mediated deletion and maintained on a C57BL/6J genetic background as originally described [22 (link)]. Adiponectin-Cre mice were mice purchased from Jackson Labs (Bar Harbor, ME, USA) and were derived from the originally described colony and bred onto a C57BL/6J background [21 (link)]. Mice which contain both the Adiponectin-Cre and the flox HO-1 alleles are considered knockouts while mice which lack the Adiponectin-Cre and only contain the flox HO-1 allele are considered Flox mice. Mice were housed under standard conditions until 6 weeks of age after which time some mice were switched to a 60% high-fat diet (diet # D12492, Research Diets, Inc., New Brunswick, NJ, USA) other mice were allowed full access to standard laboratory chow. The groups of mice consumed each diet for 30 weeks.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The creation of Cnot1 conditional knockout (Cnot1loxP/loxP) mice has been previously described [29 (link)]. We backcrossed Cnot1loxP/loxP mice with C57BL/6J mice for at least eight generations. Mice were maintained on a 12 h light/dark cycle in a temperature-controlled (22 °C) barrier facility with free access to water and a normal diet (NCD, CA-1, CLEA Japan, Inc., Meguro, Tokyo, Japan). To generate adipose tissue-specific Cnot1-AKO mice, we crossed Cnot1loxP/loxP mice with Adiponectin-Cre mice (The Jackson Laboratory, Stock No: 010803, Bar Harbor, ME, USA). We used Cnot1loxP/loxP mice as controls unless otherwise indicated. Mouse experiments were approved by the Committee of Animal Experiments at Okinawa Institute of Science and Technology Graduate University (2015-122, 7/12/2015; 2012-054, 1/12/2012).

ANG2 flox/flox mice was provided by Dr. Martin Witzenrath from Charité – Universitätsmedizin Berlin. Adiponectin-Cre mice were purchased from Jackson Laboratory (Jackson Labs, Bar Harbor, ME). To evaluate whether ANG2 from the adipose tissue affects whole-body metabolism, we first created an ANG2 adipose tissue specific knockout mice model (ANG2 aKO) by cross breeding the ANG2 flox/flox to Adiponectin-Cre mice. All mice are housed under controlled temperature (22 °C) 12-hour light (06:00–17:59) to 12-hour dark (18:00–05:59) cycles at Animal Care Facility at Virginia Commonwealth University. For all experiments, male and female mice aged 8-weeks were used for long term HFD (45 kcal% fat, D12451i, Research Diets) feeding.

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.
