| 1 | Targeting ferroptosis suppresses osteocyte glucolipotoxicity and alleviates diabetic osteoporosis显示文摘Diabetic osteoporosis(DOP) is the leading complication continuously threatening the bone health of patients with diabetes. A key pathogenic factor in DOP is loss of osteocyte viability. However, the mechanism of osteocyte death remains unclear. Here, we identified ferroptosis, which is iron-dependent programmed cell death, as a critical mechanism of osteocyte death in murine models of DOP. The diabetic microenvironment significantly enhanced osteocyte ferroptosis in vitro, as shown by the substantial lipid peroxidation, iron overload, and aberrant activation of the ferroptosis pathway. RNA sequencing showed that heme oxygenase-1(HO-1) expression was notably upregulated in ferroptotic osteocytes. Further findings revealed that HO-1 was essential for osteocyte ferroptosis in DOP and that its promoter activity was controlled by the interaction between the upstream NRF2 and c-JUN transcription factors. Targeting ferroptosis or HO-1 efficiently rescued osteocyte death in DOP by disrupting the vicious cycle between lipid peroxidation and HO-1 activation, eventually ameliorating trabecular deterioration. Our study provides insight into DOP pathogenesis, and our results provide a mechanism-based strategy for clinical DOP treatment. | Yiqi Yang Yixuan Lin Minqi Wang Kai Yuan Qishan Wang Pei Mu Jingke Du Zhifeng Yu Shengbing Yang Kai Huang Yugang Wang Hanjun Li Tingting Tang | 2022 | Bone Research2022，10，3： | 19 |
| 2 | QTG-Seq Accelerates QTL Fine Mapping through QTL Partitioning and Whole-Genome Sequencing of Bulked Segregant Samples显示文摘Deciphering the genetic mechanisms underlying agronomic traits is of great importance for crop improvement. Most of these traits are controlled by multiple quantitative trait loci (QTLs), and identifying the underlying genes by conventional QTL fine-mapping is time-consuming and labor-intensive. Here, we devised a new method, named quantitative trait gene sequencing (QTG-seq), to accelerate QTL fine-mapping. QTGseq combines QTL partitioning to convert a quantitative trait into a near-qualitative trait, sequencing of bulked segregant pools from a large segregating population, and the use of a robust new algorithm for identifying candidate genes. Using QTG-seq, we fine-mapped a plant-height QTL in maize (Zea mays L.), qPH7, to a 300-kb genomic interval and verified that a gene encoding an NF-YC transcription factor was the functional gene. Functional analysis suggested that qPH7-encoding protein might influence plant height by interacting with a CO-like protein and an AP2 domain-containing protein. Selection footprint ana卜 ysis indicated that qPH7 was subject to strong selection during maize improvement. In summary, QTG-seq provides an efficient method for QTL fine-mapping in the era of “big data'. | Hongwei Zhang Xi Wang Qingchun Pan Pei Li Yunjun Liu Xiaoduo Lu Wanshun Zhong Minqi Li Linqian Han Juan Li Pingxi Wang Dongdong Li Yan Liu Qing Li Fang Yang Yuan-Ming Zhang Guoying Wang Lin Li | 2019 | Molecular Plant2019，12，3： | 13 |

| 8 | Host-Defense-Peptide-Mimickingβ-Peptide Polymer Acting as a Dual-Modal Antibacterial Agent by Interfering Quorum Sensing and Killing Individual Bacteria Simultaneously显示文摘Host defense peptides(HDPs)are one of the potentially promising agents for infection diseases due to their broad spectrum and low resistance rate,but their clinical applications are limited by proteolytic instability,high-cost,and complicated synthesis process.Here,we report a host-defense-peptidemimickingβ-peptide polymer that resists proteolysis to have enhanced the activity under physiological conditions,excellent antimicrobial efficiency even at high density of bacteria,and low cost for preparation.Theβ-peptide polymer demonstrated quorum sensing(QS)interference and bactericidal effect against both bacterial communities and individual bacterium to simultaneously block bacterial communication and disrupt bacterial membranes.The hierarchical QS network was suppressed,and main QS signaling systems showed considerably down-regulated gene expression,resulting in excellent biofilm eradication and virulence reduction effects.The dual-modal antibacterial ability possessed excellent therapeutic effects in Pseudomonas aeruginosa pneumonia,which could inhibit biofilm formation and exhibit better antibacterial and anti-inflammatory efficiency than clinically used antibiotics,levofloxacin.Furthermore,theβ-peptide polymer also showed excellent therapeutic effect Escherichia coli pyogenic liver abscess.Together,we believed that theβ-peptide polymer had a feasible clinical potential to treat bacterial infection diseases. | Wanlin Li Ximian Xiao Yuchen Qi Xiuhui Lin Huiqun Hu Minqi Shi Min Zhou Weinan Jiang Longqiang Liu Kang Chen Kai Wang Runhui Liu Min Zhou | 2023 | Research2023，，4： | 0 |
