Paternal cold exposure enhances brown adipose tissue sensitivity in offspring and ameliorates diet induced obesity

ABSTRACT: Research in recent years has focused on environmental effects that control tissue functionality and systemic metabolism. We show here in a retrospective analysis that presence of brown adipocytes and date of birth are correlated and linked to BMI. In a mouse model system, we demonstrate that pre-conception cold exposure leads to improved systemic metabolism and protects from diet induced obesity, through the sperm via the paternal lineage. Using a brown fat ablation model, we show that this effect is mediated by brown adipose tissue. Furthermore, through RNAseq and DNA methylation analysis we identify Adrb3 as a putative signaling mechanism which could mediate the effects of pre-conception cold exposure and could account for the heterogeneity of brown adipose tissue responsiveness. Taken together, our results identify paternal cold exposure as a stimulus which induces a hyper-active state in brown adipose tissue leading to improved adaptation to overnutrition and hypothermia in the offspring.

A Stat6/Pten axis links cold exposure with T cell tolerance in adipose tissue

Project description:Obesity and type-2 diabetes are associated with tissue-inflammation and metabolic defects in fat depots. Foxp3+regulatory T(Treg) cells mediate T-cell tolerance, thereby controlling tissue inflammation. However, the molecular underpinnings how environmental stimuli interlink T-cell tolerance with adipose tissue function remain largely unknown. Here, we report that cold exposure or beta3-adrenergic receptor (ADRB3) stimulation induces T-cell tolerance in vitro and in murine and humanized models. Tolerance induction was verified by CD4+T-cell-proteomes revealing higher protein expression of Foxp3 regulatory networks. Specifically, Ragulator-interacting protein C17orf59, which limits mTORC1 activity, was upregulated by either ADRB3-stimulation or cold-exposure, and therefore might enhance Treg induction. By loss and gain-of-function studies, including Treg depletion and transfers in vivo, we demonstrated that a T-cell-specific Stat6/Pten axis links cold-exposure or ADRB3 stimulation with Foxp3+Treg induction and adipose tissue function. Our findings open new avenues in understanding tissue-specific T-cell tolerance and the design of precision concepts toward personalized immune-metabolic health.

LC-MS/MS proteomic analysis of mouse brown adipose tissues

Project description:This project aims to identify the proteins present in RNA granules of brown adipose tissue upon exposure to cold challenge. Wild type C57BL/6J mice were born and raised at thermoneutrality and were then subjected to cold exposure for 90 minutes. Brown adipose tissues were collected, and the protein lysates of RNA granules isolated from the brown adipose tissues were separated using SDS-PAGE gels and visualized with Coomassie stain. The protein bands were subsequently excised for downstream sample processing.

Cold-induced changes in gene expression in brown adipose tissue, white adipose tissue and liver

Project description:Cold exposure imposes a metabolic challenge to mammals that must be met by a coordinated repsonse in different tissues to prevent hypothermia. This study reports analysis of transcriptome profiles in brown adipose tissue, liver, white adipose of mice in repsonse to 24 hour cold exposure Total RNA was extracted from brown adipose, whie adipose and liver from cold treated and control plants. 3 replicates of brown adipose and white adipose and 2 replicates of liver samples.

Transcriptional control of thermogenesis by early B cell proteins [RNA-seq]

Project description:Early B Cell Factor 2 (EBF2) is required for brown adipose tissue basal thermogenic gene expression; however, it was unknown whether chronic cold exposure normalized the expression of thermogenic genes in Ebf2 mutant mice. We examined the transcriptome of Ebf2 WT and mutant brown adipose tissue in mice housed at room temperature or one week of cold exposure.

Transcriptional control of thermogenesis by early B cell proteins [ChIP-seq]

Project description:Early B Cell Factor 2 (EBF2) is required for brown adipose tissue basal thermogenic gene expression; however, it was unknown whether chronic cold exposure normalized the enhancer landscape of Ebf2 mutant mice. We profiled H3K27Ac binding in Ebf2 WT and mutant brown adipose tissue in mice housed at room temperature or one week of cold exposure.

Transcriptome profiling of brown adipose tissue during cold exposure

Project description:We applied a deep-sequencing based method – digital gene expression profiling (DGEP), to investigate gene expression in interscapular brown adipose tissue (iBAT), inguinal white adipose tissue (iWAT) and epididymal white adipose tissue (eWAT) in acute cold exposure Examination of gene expression level in 3 different adipose tissues in 3 time points, day0, day2 and day4 in cold exposure.

Brown Adipose Tissue Harbors a distinct subpopulation of regulatory T cells

Project description:Regulatory T (Treg) cells are critical determinants of both immune responses and metabolic control. Here we show that systemic ablation of Treg cells compromised the adaptation of whole-body energy expenditure to cold exposure, correlating with impairment in thermogenic marker gene expression and massive invasion of pro-inflammatory macrophages in brown adipose tissue (BAT). Indeed, BAT harbored a unique sub-set of Treg cells characterized by a unique gene signature. As these Treg cells respond to BAT activation upon cold exposure, this study defines a BAT-specific Treg sub-set with direct implications for the regulation of energy homeostasis in response to environmental stress. We isolated regulatory and conventional T cells from brown-adipose tissue of warm-conditioned or cold-conditioned mice. As controls, we harvested spleen-Treg and Tconv cells from warm-treated mice. Cells were isolated pooled organs and target cells purified by FACS. RNA was extracted and gene expression measured.
