- The black-bone chicken, known for its high melanin content, holds significant economic value due to this unique trait. Particularly notable is the prominent melanin deposition observed in its breast muscle. However, the molecular mechanisms governing melanin synthesis and deposition in the breast muscle of black-bone chickens remain largely unknown. This study employed a single-nucleus transcriptome assay to identify genes associated with melanin deposition in the breast muscle of black-bone chickens, which are presumed to influence pigmentation levels. A comprehensive analysis of the nuclear transcriptome was conducted on the breast muscle of Xuefeng black-bone chickens, encompassing 18 distinct cell types, including melanocytes. Our findings revealed that STIMATE, LRRC7, ENSGALG00000049990, and GLDC play pivotal regulatory roles in melanin deposition within the breast muscle. Further exploration into the molecular mechanisms unveiled transcription factors and protein interactions suggesting that RARB, KLF15, and PRDM4 may be crucial regulators of melanin accumulation in the breast muscle. Additionally, HPGDS, GSTO1, and CYP1B1 may modulate melanin production and deposition in the breast muscle by influencing melanocyte metabolism. Our findings also suggest that melanocyte function in the breast muscle may be intertwined with intercellular signaling pathways such as PTPRK-WNT5A, NOTCH1-JAG1, IGF1R-IGF1, IDE-GCG, and ROR2-WNT5A. Leveraging advanced snRNA-seq technology, we generated a comprehensive single-cell nuclear transcriptome atlas of the breast muscle of Xuefeng black-bone chickens. This facilitated the identification of candidate genes, regulatory factors, and cellular signals potentially influencing melanin deposition and melanocyte function. Overall, our study provides crucial insights into the molecular basis of melanin deposition in chicken breast muscle, laying the groundwork for future breeding programs aimed at enhancing black-bone chicken cultivation. - Source: PubMed

Li PengWei XuZi QiongtaoQu XiangyongHe ChangqingXiao BingGuo Songchang - Obesity is a global public health problem and is related with fatal diseases such as cancer and cardiovascular and metabolic diseases. Medical and lifestyle-related strategies to combat obesity have their limitations. White adipose tissue (WAT) browning is a promising strategy for increasing energy expenditure in individuals with obesity. Uncoupling protein 1 (UCP1) drives WAT browning. We previously screened natural products that enable induction of Ucp1 and demonstrated that these natural products induced WAT browning and increased energy expenditure in mice with diet-induced obesity. In this study, we aimed to extensively optimise the structure of compound 1, previously shown to promote WAT browning. Compound 3 s exhibited a significantly higher ability to induce Ucp1 in white and brown adipocytes than did compound 1. A daily injection of compound 3 s at 5 mg/kg prevented weight gain by 13.6 % in high-fat diet-fed mice without any toxicological observation. In addition, compound 3 s significantly improved glucose homeostasis, decreased serum triacylglycerol levels, and reduced total cholesterol and LDL cholesterol levels, without altering dietary intake or physical activity. Pharmaceutical properties such as solubility, lipophilicity, and membrane permeability as well as metabolic stability, half-life (T), and blood exposure ratio of i.p to i.v were significantly improved in compound 3 s when compared with those in compound 1. Regarding the mode of action of WAT browning, the induction of Ucp1 and Prdm4 by compounds 1 and 3 s was dependent on Akt1 in mouse embryonic fibroblasts. Therefore, this study suggests the potential of compound 3 s as a therapeutic agent for individuals with obesity and related metabolic diseases, which acts through the induction of WAT browning as well as brown adipose tissue activation. - Source: PubMed

Chang Seo-HyukSong DawoonOh SeungjunHan Saro-AreumJung Ji-ManSong No-JoonKang HeeLee SukchanAhn Jee-YinAhn SeunghyunNa Yu-RanYeom Chang-HwanPark Kye WonKu Jin-Mo - Brown and beige adipose thermogenesis are important for newborn mammals to maintain their body temperature. In addition, these thermogenic fats are regulated by multiple molecular interactions. How the long non-coding RNAs (lncRNAs) regulate adipose thermogenesis in newborn mammals upon cold exposure remains unexplored. Here, we identified lncRNAs induced by cold exposure in brown adipose tissue (BAT) of newborn goats and found that lncDGAT2 was enriched in BAT after cold exposure. Functional studies revealed that lncDGAT2 promoted brown and white adipocyte differentiation as well as thermogenic gene expression. Additionally, PRDM4 directly bound the lncDGAT2 promoter to activate the transcription of lncDGAT2 and the PRDM4-lncDGAT2 axis was essential for the brown adipocyte thermogenic gene program. These findings provide evidence for lncRNA and transcription factor regulatory functions in controlling adipose thermogenesis and energy metabolism of newborn goats. - Source: PubMed

Zhou DongkaiWang YizhiWei WeiZhou WeiGu JinKong YangYang QifanWu Yingsheng - The retrotransposon LINE-1 (L1) is central to the recent evolutionary history of the human genome and continues to drive genetic diversity and germline pathogenesis. However, the spatiotemporal extent and biological significance of somatic L1 activity are poorly defined and are virtually unexplored in other primates. From a single L1 lineage active at the divergence of apes and Old World monkeys, successive L1 subfamilies have emerged in each descendant primate germline. As revealed by case studies, the presently active human L1 subfamily can also mobilize during embryonic and brain development in vivo. It is unknown whether nonhuman primate L1s can similarly generate somatic insertions in the brain. Here we applied approximately 40× single-cell whole-genome sequencing (scWGS), as well as retrotransposon capture sequencing (RC-seq), to 20 hippocampal neurons from two rhesus macaques (). In one animal, we detected and PCR-validated a somatic L1 insertion that generated target site duplications, carried a short 5' transduction, and was present in ∼7% of hippocampal neurons but absent from cerebellum and nonbrain tissues. The corresponding donor L1 allele was exceptionally mobile in vitro and was embedded in , a gene expressed throughout development and in neural stem cells. Nanopore long-read methylome and RNA-seq transcriptome analyses indicated young retrotransposon subfamily activation in the early embryo, followed by repression in adult tissues. These data highlight endogenous macaque L1 retrotransposition potential, provide prototypical evidence of L1-mediated somatic mosaicism in a nonhuman primate, and allude to L1 mobility in the brain over the past 30 million years of human evolution. - Source: PubMed
