| 1 | Mettl3-/Mettl14-mediated mRNA N6-methyladenosine modulates murine spermatogenesis显示文摘精子发生在双 spermatogonial 干细胞(SSC ) 哪个生产 haploid 精子期间是一个区别过程。这个高度专业化的过程精确在 transcriptional, posttranscriptional,和翻译层次被控制。这里,我们报导那 N 6-methyladenosine (m 6 一) ,调整基因表示的一个 epitranscriptomic 标记,在精子发生期间起必要作用。我们现在的全面 m 6 从五个发展阶段的老鼠 spermatogenic 房间的 mRNA methylomes:无差别的 spermatogonia,类型 A 1 spermatogonia, preleptotene spermatocytes, pachytene/diplotene spermatocytes,和圆 spermatids。m 6 有 Vasa-Cre 的 RNA methyltransferase Mettl3 或 Mettl14 引起 m 6 SSC 的 A 和弄空。m 6 为 SSC 增长 / 区别被要求的抄本的一个弄空 dysregulates 翻译。在有 Stra8-GFPCre 的先进细菌房间的 Mettl3 和 Mettl14 的联合删除破坏精子形式,而有在先进细菌房间的 Mettl3 或 Mettl14 的单个删除的老鼠显示出正常精子发生。从双异种老鼠展览的 spermatids 损害了为精子形式是必要的 haploid 特定的基因的翻译。这研究加亮 mRNA m 6 在 germline 开发的修正,潜在地保证在精子发生的不同阶段协调了翻译。 | Zhen Lin Phillip J Hsu Xudong Xing Jianhuo Fang Zhike Lu Qin Zou Ke-Jia Zhang Xiao Zhang Yuchuan Zhou Teng Zhang Youcheng Zhang Wanlu Song Guifang Jia Xuerui Yang Chuan He Ming-Han Tong | 2017 | Cell Research2017，27，10： | 61 |

| 3 | Brain developmental and cortical connectivity changes in transgenic monkeys carrying the human-specific duplicated gene SRGAP2C显示文摘Human-specific duplicated genes contributed to phenotypic innovations during the origin of our own species, such as an enlarged brain and highly developed cognitive abilities. While prior studies on transgenic mice carrying the human-specific SRGAP2C gene have shown enhanced brain connectivity, the relevance to humans remains unclear due to the significant evolutionary gap between humans and rodents. In this study, to investigate the phenotypic outcome and underlying genetic mechanism of SRGAP2C, we generated transgenic cynomolgus macaques (Macaca fascicularis) carrying the human-specific SRGAP2C gene. Longitudinal MRI imaging revealed delayed brain development with region-specific volume changes, accompanied by altered myelination levels in the temporal and occipital regions. On a cellular level, the transgenic monkeys exhibited increased deep-layer neurons during fetal neurogenesis and delayed synaptic maturation in adolescence. Moreover, transcriptome analysis detected neotenic expression in molecular pathways related to neuron ensheathment, synaptic connections, extracellular matrix and energy metabolism. Cognitively, the transgenic monkeys demonstrated improved motor planning and execution skills. Together, our findings provide new insights into the mechanisms by which the newly evolved gene shapes the unique development and circuitry of the human brain. | Xiaoyu Meng Qiang Lin Xuerui Zeng Jin Jiang Min Li Xin Luo Kaimin Chen Haixu Wu Yan Hu Cirong Liu Bing Su | 2023 | National Science Review2023，10，11： | 1 |
| 4 | Phosphatidylserine externalized on the colonic capillaries as a novel pharmacological target for IBD therapy显示文摘Inflammatory bowel disease(IBD)is a chronic and relapsing disorder for many people associated with poor health.Although there are some clinical drugs for IBD treatment,the development of effective therapeutics on IBD patients has always been necessary.Here,we show that externalized phosphatidylserine(PS)is observed on the surface of colonic capillaries.Annexin A5(ANXA5)with high affinity for PS has a good targeting to the colon and effectively alleviates experimental colitis.In contrast,ANXA5 mutant(A5m)lacking the PS-binding ability,has no accumulation in the colon and no therapeutic effects on colitis.Mechanistic investigations indicate that ANXA5 reduces the inflammatory cell infiltration by inhibiting endothelial cell activation dependent on PS-binding ability.With the increasing of PS exposure on activated HUVECs(human umbilical vein endothelial cells),ANXA5 binding induces the internalization of TLR4 via PS-dependent endocytosis.We provide new insights on the molecular mechanism of ANXA5 for its anti-inflammatory effect.Our data suggest that PS-externalization is a potential target of ANXA5 aiming at targeted drug delivery(TDD)for IBD treatment. | Xuerui Zhang Lulu Song Lin Li Banghui Zhu Lina Huo Zhaoqing Hu Xinran Wang Jie Wang Mengyue Gao Jing Zhang Zichun Hua | 2021 | Signal Transduction and Targeted Therapy2021，6，7： | 1 |
| 5 | Soil properties drive the bacterial community to cadmium contamination in the rhizosphere of two contrasting wheat(Triticum aestivum L.)genotypes显示文摘Cadmium(Cd)bioavailability in the rhizosphere makes an important difference in grain Cd accumulation in wheat.Here,pot experiments combined with 16S rRNA gene sequencing were conducted to compare the Cd bioavailability and bacterial community in the rhizosphere of two wheat(Triticum aestivum L.)genotypes,a low-Cd-accumulating genotype in grains(LT)and a high-Cd-accumulating genotype in grains(HT),grown on four different soils with Cd contamination.Results showed that there was non-significant difference in total Cd concentration among four soils.However,except for black soil,DTPA-Cd concentrations in HT rhizospheres were higher than those of LT in fluvisol,paddy soil and purple soil.Results of 16S rRNA gene sequencing showed that soil type(52.7%)was the strongest determinant of root-associated community,while there were still some differences in rhizosphere bacterial community composition between twowheat genotypes.Taxa specifically colonized in HT rhizosphere(Acidobacteria,Gemmatimonadetes,Bacteroidetes and Deltaproteobacteria)could participate inmetal activation,whereas LT rhizosphere was highly enriched by plant growth-promoting taxa.In addition,PICRUSt2 analysis also predicted high relative abundances of imputed functional profiles related to membrane transport and amino acid metabolism in HT rhizosphere.These results revealed that the rhizosphere bacterial community may be an important factor regulating Cd uptake and accumulation in wheat and indicated that the high Cd-accumulating cultivar might improve Cd bioavailability in the rhizosphere by recruiting taxa related to Cd activation,thus promoting Cd uptake and accumulation. | Min Lu Lukuan Huang Qiong Wang Xuerui Cao Qiang Lin Zhenli He Ying Feng Xiaoe Yang | 2023 | Journal of Environmental Sciences2023，，6： | 0 |
