| 1 | Mapping and analysis of a spatiotemporal H3K27ac and gene expression spectrum in pigs显示文摘The limited knowledge of genomic noncoding and regulatory regions has restricted our ability to decipher the genetic mechanisms underlying complex traits in pigs. In this study, we characterized the spatiotemporal landscape of putative enhancers and promoters and their target genes by combining H3K27ac-targeted Ch IP-Seq and RNA-Seq in fetal(prenatal days 74–75) and adult(postnatal days 132–150) tissues(brain, liver, heart, muscle and small intestine) sampled from Asian aboriginal Bama Xiang and European highly selected Large White pigs of both sexes. We identified 101,290 H3K27ac peaks, marking 18,521promoters and 82,769 enhancers, including peaks that were active across all tissues and developmental stages(which could indicate safe harbor locus for exogenous gene insertion) and tissue-and developmental stage-specific peaks(which regulate gene pathways matching tissue-and developmental stage-specific physiological functions). We found that H3K27ac and DNA methylation in the promoter region of the XIST gene may be involved in X chromosome inactivation and demonstrated the utility of the present resource for revealing the regulatory patterns of known causal genes and prioritizing candidate causal variants for complex traits in pigs. In addition, we identified an average of 1,124 super-enhancers per sample and found that they were more likely to show tissue-specific activity than ordinary peaks.

| 3 | Cloning,Functional Characterization and Expression Analysis of the elovl4a Gene in the Large Yellow Croaker(Larimichthys crocea)显示文摘Elovl4 is a fatty acyl elongase which participates in the biosynthesis of long-chain polyunsaturated fatty acids(LCPUFA).Herein we isolated and functionally characterized the elovl4a gene in the large yellow croaker Larimichthys crocea,and investigated the regulatory effects of transcription factors Hnf4α,Lxrα,Pparαon the activity of elovl4a promoter.Tissue expression pattern revealed that elovl4a was widely expressed in several tissues and predominantly in brain.Heterologous expression in yeast showed that L.crocea Elovl4a could effectively elongate both C18 and C20 PUFA substrates to C22 fatty acid.In addition,the affinity of large yellow croaker Elovl4a to n-6 series fatty acids is weak and cannot prolong 18:2n-6 and 18:3n-6.Moreover,L.crocea elovl4a reporter activities were elevated by 1.31-,1.39-and 1.48-fold via over-expression of Lxrα,Pparαand Hnf4α,respectively.The above findings can enrich the knowledge of biosynthesis pathway of LC-PUFA in the large yellow croaker and contribute to elucidate the LC-PUFA anabolism mechanism in fish. | ZHANG Meng LI Wanbo ZHU Yangyang WANG Weijia WANG Zhiyong | 2021 | Journal of Ocean University of China2021，20，6： | 0 |
| 4 | Fetuin-A is an immunomodulator and a potential therapeutic option in BMP4-dependent heterotopic ossification and associated bone mass loss显示文摘Heterotopic ossification(HO)is the abnormal formation of bone in extraskeletal sites.However,the mechanisms linking HO pathogenesis with bone mass dysfunction remain unclear.Here,we showed that mice harboring injury-induced and BMP4-dependent HO exhibit bone mass loss similar to that presented by patients with HO.Moreover,we found that injury-induced hyperinflammatory responses at the injury site triggered HO initiation but did not result in bone mass loss at 1 day post-injury(dpi).In contrast,a suppressive immune response promoted HO propagation and bone mass loss by 7 dpi.Correcting immune dysregulation by PD1/PDL1 blockade dramatically alleviated HO propagation and bone mass loss.We further demonstrated that fetuin-A(FetA),which has been frequently detected in HO lesions but rarely observed in HO-adjacent normal bone,acts as an immunomodulator to promote PD1 expression and M2 macrophage polarization,leading to immunosuppression.Intervention with recombinant FetA inhibited hyperinflammation and prevented HO and associated bone mass loss.Collectively,our findings provide new insights into the osteoimmunological interactions that occur during HO formation and suggest that FetA is an immunosuppressor and a potential therapeutic option for the treatment of HO. | Chen Kan Jiazhao Yang Haitao Fan Yuanjuan Dai Xingxing Wang Rui Chen Jia Liu Xiangyue Meng Wei Wang Guiling Li Jiao Zhou Ya Zhang Wanbo Zhu Shiyuan Fang Haiming Wei Hong Zheng Siying Wang Fang Ni | 2022 | Bone Research2022，10，4： | 0 |
