| 1 | Overexpression of Lrp5 enhanced the anti-breast cancer effects of osteocytes in bone显示文摘Osteocytes are the most abundant cells in bone,which is a frequent site of breast cancer metastasis.Here,we focused on Wnt signaling and evaluated tumor-osteocyte interactions.In animal experiments,mammary tumor cells were inoculated into the mammary fat pad and tibia.The role of Lrp5-mediated Wnt signaling was examined by overexpressing and silencing Lrp5 in osteocytes and establishing a conditional knockout mouse model.The results revealed that administration of osteocytes or their conditioned medium(CM)inhibited tumor progression and osteolysis.Osteocytes overexpressing Lrp5 or β-catenin displayed strikingly elevated tumor-suppressive activity,accompanied by downregulation of tumor-promoting chemokines and upregulation of apoptosis-inducing and tumor-suppressing proteins such as p53.The antitumor effect was also observed with osteocyte-derived CM that was pretreated with a Wnt-activating compound.Notably,silencing Lrp5 in tumors inhibited tumor progression,while silencing Lrp5 in osteocytes in conditional knockout mice promoted tumor progression.Osteocytes exhibited elevated Lrp5 expression in response to tumor cells,implying that osteocytes protect bone through canonical Wnt signaling.Thus,our results suggest that the Lrp5/β-catenin axis activates tumor-promoting signaling in tumor cells but tumor-suppressive signaling in osteocytes.We envision that osteocytes with Wnt activation potentially offer a novel cell-based therapy for breast cancer and osteolytic bone metastasis. | Shengzhi Liu Di Wu Xun Sun Yao Fan Rongrong Zha Aydin Jalali Yan Feng Kexin Li Tomohiko Sano Nicole Vike Fangjia Li Joseph Rispoli Akihiro Sudo Jing Liu Alexander Robling Harikrishna Nakshatri Bai-Yan Li Hiroki Yokota | 2021 | Bone Research2021，9，4： | 1 |

| 3 | Pistachio genomes provide insights into nut tree domestication and ZW sex chromosome evolution显示文摘Pistachio is a nut crop domesticated in the Fertile Crescent and a dioecious species with ZW sex chromosomes.We sequenced the genomes of Pistacia vera cultivar(cv.)Siirt,the female parent,and P.vera cv.Bagyolu,the male parent.Two chromosome-level reference genomes of pistachio were generated,and Z and W chromosomes were assembled.The ZW chromosomes originated from an autosome following the first inversion,which occurred approximately 8.18 Mya.Three inversion events in the W chromosome led to the formation of a 12.7-Mb(22.8%of the W chromosome)non-recombining region.These W-specific sequences contain several genes of interest that may have played a pivotal role in sex determination and contributed to the initiation and evolution of a ZW sex chromosome system in pistachio.The W-specific genes,including defA,defA-like,DYT1,two PTEN1,and two tandem duplications of six VPS13A paralogs,are strong candidates for sex determination or differentiation.Demographic history analysis of resequenced genomes suggest that cultivated pistachio underwent severe domestication bottlenecks approximately 7640 years ago,dating the domestication event close to the archeological record of pistachio domestication in Iran.We identified 390,211,and 290 potential selective sweeps in 3 cultivar subgroups that underlie agronomic traits such as nut development and quality,grafting success,flowering time shift,and drought tolerance.These findings have improved our understanding of the genomic basis of sex determination/differentiation and horticulturally important traits and will accelerate the improvement of pistachio cultivars and rootstocks. | Salih Kafkas Xiaokai Ma Xingtan Zhang Hayat Topc¸u Rafael Navajas-Pérez Ching Man Wai Haibao Tang Xuming Xu Mortaza Khodaeiaminjan Murat Güney Aibibula Paizila Harun Karcı Xiaodan Zhang Jing Lin Han Lin Roberto de la Herrán Carmelo Ruiz Rejón Jerson Alexander García-Zea Francisca Robles Coral del Val Muñoz Agnes Hotz-Wagenblatt Xiangjia Jack Min HakanÖzkan Elmira Ziya Motalebipour Hatice Gozel Nergiz C¸oban Nesibe Ebru Kafkas Andrej Kilian HuaXing Huang Xuanrui Lv Kunpeng Liu Qilin Hu Ewelina Jacygrad William Palmer Richard Michelmore Ray Ming | 2023 | Plant Communications2023，4，3： | 0 |
