Acute and long-term effects of psilocybin on energy balance and feeding behavior in mice

Project description:Psilocybin, and other serotonergic psychedelics, have re-emerged as therapeutics for neuropsychiatric disorders, including addiction. Psilocybin induces long-lasting effects on behavior, likely due to its profound ability to alter consciousness and augment neural connectivity and plasticity. Impaired synaptic plasticity in obesity contributes to ‘addictive-like’ behaviors, including heightened motivation for palatable food, and excessive food seeking and consumption. Here, we evaluate the effects of psilocybin on feeding behavior, energy metabolism and as a weight-lowering agent in mice. We demonstrate that a single dose of psilocybin substantially alters the prefrontal cortex transcriptome but has no acute or long-lasting effects on food intake or body weight in diet-induced obese mice or in genetic mouse models of obesity. Similarly, sub-chronic microdosing of psilocybin has no metabolic effects in obese mice and psilocybin does not augment glucagon-like peptide-1 (GLP-1) induced weight loss or enhance diet-induced weight loss. A single high dose of psilocybin reduces sucrose preference but fails to counter binge-like eating behavior. Although these preclinical data discourage clinical investigation, there may be nuances in the mode of action of psychedelic drugs that are difficult to capture in rodent models, and thus require human evaluation to uncover.

Isolating Independent Effects of Diet/Energy Balance and Body Weight on Behavior and Metabolic Health

Project description:Associated with numerous metabolic and behavioral abnormalities, obesity is classified by metrics reliant on body weight (such as body mass index). However, overnutrition is the common cause of obesity, and may independently contribute to these obesity-related abnormalities. The goal of this study is to isolate ‘diet/energy balance’ effects independent from ‘body weight’ effects on various metabolic and behavioral parameters using the Diet Switch feeding paradigm in mice. [We conducted] unbiased gene expression analysis of the nutrient-sensing circumventricular hypothalamus [using RNA-seq]. Remarkably, only two genes responded to diet/energy balance (neuropeptide y [npy] and agouti-related peptide [agrp]), while others were related only to body weight. Furthermore, linear regression models revealed that npy and agrp showed similar modifiability by diet/energy balance and body weight compared to electroencephalographic-measured sleep/wake behavior.

Bovine granulosa cells of dominant follicles at 60 days postpartum; effect of negative energy balance on transcriptome

Project description:Granulosa cells of dominant follicles originating from dairy cows with severe negative energy balance (BHBH) or mild negative energy balance (BHBL) were compared. Mild negative energy balance (BHBL) is the reference. Two conditions experiment (BHBH and BHBL); Four pools of 3 biological replicates for each group (total = 12 cows for each group); Two technical replicates per pool (dye-swap).

The ancestral western diet causes transgenerational increase in offspring feeding behavior with parallel alterations in brain mitochondrial proteome and miRNAs.

Project description:Childhood obesity traces its roots to the parental lifestyle and eating habits. Familial clustering of obesity indicates that children’s feeding behavior is a result of a complex interplay between cultural inheritance, genetics, and epigenetics. In the current study, we asked a question if epigenetic factors, such as ancestral diet, could program offspring feeding behavior in a fruit fly model. Here we show that ancestral caloric overload produces a generational shift in the offspring’s feeding behavior, with a concomitant alteration in activity, triglycerides, and brain mitochondrial density. Mechanistically, we find the generational changes to be associated with alterations in brain mitochondrial proteome and miRNAs. The findings identify ancestral nutrition as a critical factor in the generational programming of feeding behavior.
