Temporal profile of germ-free and conventionally raised male mice (epididymal white adipose tissue (WAT))

ABSTRACT: Gut microbiota and the circadian clock both regulate metabolism. The circadian clock and associated feeding rhythms were shown to impact on the microbial community. However, to what extent gut microbiota reciprocally affect daily rhythms of gene expression and physiology in the host remains elusive. Here, we analyzed the transcriptomes of male and female germ-free mice. While this revealed subtle changes in circadian clock gene expression in liver, intestine, and white adipose tissue, germ-free mice showed considerably altered expression of genes associated to rhythmic physiology. Strikingly, absence of microbiome severely compromised liver sex-dimorphism at the transcriptome and metabolome level. Their sex-specific rhythmicity was strongly attenuated. The resulting feminization of male and masculinization of female hepatic gene expression in germ-free animals is likely caused by altered sex-dimorphism in sex and growth hormone secretion, linked to differential activation of xenobiotic receptors. This defines a novel mechanism by which the gut microbiome regulates host metabolism.

The mouse microbiome is required for sex-specific diurnal rhythms of gene expression and metabolism

Project description:The circadian clock and associated feeding rhythms have a profound impact on metabolism and the gut microbiome. To what extent microbiota reciprocally affect daily rhythms of physiology in the host remains elusive. Here, we analyzed transcriptome and metabolome profiles of male and female germ-free mice. While mRNA expression of circadian clock genes revealed subtle changes in liver, intestine, and white adipose tissue, germ-free mice showed considerably altered expression of genes associated to rhythmic physiology. Strikingly, absence of microbiome severely compromised liver sexual dimorphism, showing strongly attenuated sex-specific rhythmicity. The resulting feminization of male and masculinization of female germ-free animals is likely caused by altered sexual development and growth hormone secretion, associated to differential activation of xenobiotic receptors. This defines a novel mechanism by which the microbiome regulates host metabolism.

Total RNA-Seq of primary hepatocytes treated with serum of conventionally raised (convR) and Germ-free (GF) male and female mice.

Project description:Gut microbiota and the circadian clock are both key regulators of the metabolic processes. Although recent evidence points to the impact of the circadian clock on microbiota, gut microbiota effect on diurnal host gene expression remains elusive. A transcriptome analysis of germ-free mice reveals subtle changes in circadian clock gene expression. However, a lack of microbiome leads to liver feminization and alters the expression of male-specific genes involved in lipid metabolism and xenobiotic detoxification associated with sustained activation of the Growth Hormone pathway. These results emphasize the mutual interaction of gut microbiota and its host even on unexpected functions.

Gut microbiota directs PPARγ-driven reprogramming of the liver circadian clock by nutritional challenge

Project description:The liver circadian clock is reprogrammed by nutritional challenge through the rewiring of specific transcriptional pathways. As the gut microbiota is tightly connected to host metabolism, whose coordination is governed by the circadian clock, we explored whether gut microbes influence circadian homeostasis and how they distally control the peripheral clock in the liver. Using fecal transplant procedures we reveal that, in response to high fat diet, the gut microbiota drives PPARγ-mediated activation of newly oscillatory transcriptional programs in the liver. Moreover, antibiotics treatment prevents PPARγ-driven transcription in the liver, underscoring the essential role of gut microbes in clock reprogramming and hepatic circadian homeostasis. Thus, a specific molecular signature characterizes the influence of the gut microbiome in the liver, leading to the transcriptional rewiring of hepatic metabolism. We used microarray to quantify the tissue specific expression level of circadian genes in terms of total RNA.

Colonic and cecal microbiome profiles in response to different environmental light-dark cycles

Project description:It is well known that host-microbes and immunity interactions are influenced by dietary patterns, as well as daily environmental light-dark (LD) cycles that entrain circadian rhythms in the host. Emerging data has highlighted the importance of diet patterns and timing on the interaction among circadian rhythms, gut microbiome, and immunity, however, their impacts on LD cycles are less reported. Therefore, we aim to study how LD cycles regulate the homeostatic crosstalk between gut microbiome, hypothalamic and hepatic circadian clock oscillations and immunity. We hypothesized that different environmental LD cycles: (1) constant darkness, LD0/24; (2) short light, LD8/16; (3) normal LD cycle, LD12/12; (4) long light, LD16/8; and (5) constant light, LD24/0, may affect immunity and metabolism to varying degrees. Therefore, 240 mice were managed with chow diets (CD) and antibiotics treatments (ABX) under five different LD cycles for 42 days. The colonic (co) and cecum (ce) contents were obtained for studying their impacts on gut microbiome using 16S rRNA sequencing.
