Project description:To investigate the impact of the reproductive cycle on adipose tissue, we analyzed transcriptome profiling across the entire estrous cycle in the adipose tissue of female mice.
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 liver (LIV), hypothalamus (HYP), inguinal white adipose tissue (iWAT), ileum epithelium (ILE), colon epithelium (COL), jejunum epithelium (JEJ), cecum epithelium (CEC), spleen (SPL), mammary gland (MAG), and thymus gland (THY) tissues were obtained for studying their impacts immunity using RNA-Seq data.
Project description:Transcriptional profiling of transgenic mice specifically expressing amphiregulin in white adipose tissues. The objective of this study is to explore gene expression profiles of adipose tissues in response to amphiregulin overexpression.
Project description:To investigate the role of somatosensory innervation of adipose tissues, we unilaterally ablate sensory innervation of adipose tissues, and profiled the gene expression in the inguinal adipose tissues 4 weeks after sensory ablation surgery.
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.
Project description:FoxO1 is a transcription factor known to regulate metabolism and functions of different tissues. To study the role of FoxO1 in adipose biology, this study examined the transcript profile in inguinal and gonadal adipose tissues from conditional adipose FoxO1 knockout mice and floxed FoxO1 (control) mice.
Project description:Gene expression profiling of supraclavicular brown, interscapular brown, inguinal white, and epididymal white adipose tissues from C57BL/6 male mice was performed by RNA-sequencing.
