Phosphoribotrap-based profiling of activated hypothalamic cells during acute high-fat diet (HFD)-feeding
To identify novel neurocircuits activated upon short-term HFD feeding, we employed phosphoribotrap-profiling, which allows for the unbiased identification of alterations in neuronal activation via immunoprecipitation of phosphorylated S6 ribosomal protein-tagged ribosomes from hypothalamic extracts of mice exposed to either 3 days of normal chow diet or HFD-feeding. We have analyzed mRNA selectively expressed in hypothalamic cells activated by a either normal chow diet (NCD)-feeding for 3 days or high fat diet (HFD)-feeding for 3 days. 10-week-old male C57/BL6N mice were put either on a normal chow diet or a high fat diet for 3 days. Afterwards, mice were sacrificed by cervical dislocation. The hypothalamus was rapidly dissected using a stainless steel brain matrix and immediately frozen in liquid nitrogen. Hypothalamic tissues were pooled (8 per IP). Overall design: Hypothalamic translatome of activated cells of 10 week old C57/BL6N mice, fed either a normal chow diet (NCD) for 3 days or a high-fat diet (HFD) for 3 days.
