Dietary Intervention in Intestinal AMPK Knockout Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Male mice were fed a CD (E15745-047, Ssniff, Germany) containing 70 kJ% carbohydrate, 10 kJ% fat, and 20 kJ% protein or HFD (E15742-347, Ssniff, Germany) containing 21 kJ% carbohydrate, 60 kJ% fat (primarily lard), and 19 kJ% protein. Starting at 10 weeks of age, co-housed WT and IEC AMPK KO mice received either a CD or HFD for 10 weeks. At weaning, WT and i-IEC AMPK KO mice were stratified on the basis of their genotype and were assigned to separate cages to receive either CD or HFD for 16 weeks. To analyze whole-body composition, unanesthetized mice were scanned using an NMR Minispec + LF90II (Bruker Optics).

Sex Hormone Replacement and Ablation/Activation in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adult mice (8–12 week-old female mice or 14-16 week-old male mice) were bilaterally ovariectomized or castrated. For sex hormone replacement, a 2 cm length of silastic tubing (inner diameter: 1.58 mm; outer diameter: 3.18 mm) containing 36 μg 17β-estradiol/mL (E2758, Sigma)42 in sesame oil or testosterone powder43 (link) (T1500, Sigma) were inserted on the dorsal aspect of the animal’s neck immediately after gonadectomy. Mice were allowed to recover for 1 week before further treatment.
For ablation experiments, 8- to 10-week-old female mice or 14- to 16-week-old male mice were intraperitoneally injected with 20 ng/g bodyweight diphtheria toxin (DT; 322326, EMD Millipore) twice with a 3-day interval between injections. For activation experiments, 2.5 mg of clozapine-N-oxide (CNO; Tocris Bioscience) in 200 ml of drinking water was administered to the mice with a high-fat diet (22% carb, 24% protein, 54% fat, E15742-347, Ssniff). For FSH administration, mice with a high-fat diet received daily 30 IU/kg i.p FSH (GONAL-f, Merck) injections. Mice were weighed and monitored daily before being euthanized as experimental mice. Mice were humanely euthanized if postsurgical complications progressed to a pre-defined humane endpoint at which the mice started to suffer.

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.
