Epigenetic mechanisms are integral to plant growth, development, and adaptation to environmental stimuli. Over the past two decades,our comprehension of these complex regulatory processes has expanded remarkably, producing a substantial body of knowledge on both locus-specific mechanisms and genome-wide regulatory patterns. Studies initially grounded in the model plant Arabidopsis have been broadened to encompass a diverse array of crop species, revealing the multifaceted roles of epigenetics in physiological and agronomic traits. With recent technological advancements, epigenetic regulations at the single-cell level and at the large-scale population level are emerging as new focuses. This review offers an in-depth synthesis of the diverse epigenetic regulations, detailing the catalytic machinery and regulatory functions. It delves into the intricate interplay among various epigenetic elements and their collective influence on the modulation of crop traits. Furthermore, it examines recent breakthroughs in technologies for epigenetic modifications and their integration into strategies for crop improvement. The review underscores the transformative potential of epigenetic strategies in bolstering crop performance, advocating for the development of efficient tools to fully exploit the agricultural benefits of epigenetic insights.

Novel translational strategies in colorectal cancer research

引用

World Journal of Gastroenterology 2007年第44期13卷 5902-5910页

作者： Ignacio Gil-Bazo cancer biology & genetics Program Memorial Sloan-Kettering Cancer Center New York NY 10021 United States

Defining translational research is still a complex task. In oncology, translational research implies using our basic knowledge learnt from in vitro and in vivo experiments to directly improve diagnostic tools and therapeutic approaches in cancer patients. Moreover, the better understanding of human cancer and its use to design more reliable tumor models and more accurate experimental systems also has to be considered a good example of translational research. The identification and characterization of new molecular markers and the discovery of novel targeted therapies are two main goals in colorectal cancer translational research. However, the straightforward translation of basic research findings, specifically into colorectal cancer treatment and vice versa is still underway. In the present paper, a summarized view of some of the new available approaches on colorectal cancer translational research is provided. Pros and cons are discussed for every approach exposed.

Lipidomics as a Principal Tool for Advancing Biomedical Research

引用

Journal of genetics and Genomics 2013年第8期40卷 375-390页

作者： Sin Man Lam Guanghou Shui State Key laboratory of Molecular Developmental biology Institute of Genetics and Developmental BiologyChinese Academy of Sciences

Lipidomics, which targets at the construction of a comprehensive map of lipidome comprising the entire lipid pool within a cell or tissue, is currently emerging as an independent discipline at the interface of lipid biology, technology and medicine. The diversity and complexity of the biological lipidomes call for technical innovation and improvement to meet the needs of various biomedical studies. The recent wave of expansion in the field of lipidomic research is mainly attributed to advances in analytical technologies, in particular, the development of new mass spectrometric and chromatographic tools for the characterization and quantification of the wide array of diverse lipid species in the cellular lipidome. Here, we review some of the key technical advances in lipidome analysis and put forth the applications of lipidomics in addressing the biological roles of lipids in numerous disease models including the metabolic syndrome, neurodegenerative diseases and infectious diseases, as well as the increasing urgency to construct the lipidome inventory for various mammalian/organism models useful for biomedical research.

RLKs orchestrate the signaling in plant male-female interaction

引用

Science China(Life Sciences) 2016年第9期59卷 867-877页

作者： Hongju Li Wei-Cai Yang State Key laboratory of Molecular Developmental biology Institute of Genetics and Developmental Biology Chinese Academy of Sciences

Different from animals, sessile plants are equipped with a large receptor-like kinase(RLK) superfamily. RLKs are a family of single trans-membrane proteins with divergent N-terminal extracellular domains capped by a signal peptide and C-terminal intracellular kinase. Researches in the last two decades have uncovered an increasing number of RLKs that regulate plant development, stress response and sexual reproduction, highlighting a dominant role of RLK signaling in cell-to-cell communications. Sexual reproduction in flowering plants is featured by interactions between the male gametophyte and the female tissues to facilitate sperm delivery and fertilization. Emerging evidences suggest that RLKs regulate almost every aspect of plant reproductive process, especially during pollination. Therefore, in this review we will focus mainly on the function and signaling of RLKs in plant male-female interaction and discuss the future prospects on these topics.

Frequent Mutation of rs13281615 and Its Association with PVT1 Expression and Cell Proliferation in Breast cancer

引用

Journal of genetics and Genomics 2014年第4期41卷 187-195页

作者： Zhiqian Zhang Zhengmao Zhu Baotong Zhang Weidong Li Xin Li Xiao Wu Lijuan Wang Liya Fu Li Fu Jin-Tang Dong Department of genetics and Cell biology Nankai University College of Life Sciences Key laboratory of Breast cancer Research Department of Breast Cancer Pathology and Research LaboratoryCancer Hospital of Tianjin Medical University Department of Hematology and Medical Oncology Emory University School of MedicineEmory Winship Cancer Institute

The q24 band of chromosome 8 （8q24） is frequently amplified in human cancers including breast cancer, and several SNPs （single nucleotide polymorphisms） at 8q24, including rs13281615, have been identified for their association with cancer risks. These SNPs are in a ＂gene desert＂ region, and their functions in cancer development remain to be illustrated, although several of the SNPs appear to influence the genes in the ＂desert＂ in a long-range manner, including the v-myc avian myelocytomatosis viral oncogene homolog （MYC） and the non- protein coding plasmacytoma variant translocation 1 （PVT1）, both of which have been implicated in human cancers. In the current study, we examined rs13281615 for its potential role in breast cancer using normal and cancer tissues from 121 Chinese women with breast cancer. In addition to confirming the association of the GG genotype of rs 13281615 with breast cancer risk, we found that germline GG genotype was significantly associated with estrogen receptor （ER） positivity, higher tumor grade and higher proliferation index. We also found frequent somatic mutations （22/121 or 18.2%） of this SNP in breast cancer. Interestingly, the majority of the mutations （17/22 or 77%） involved a G→ A change, resulting in a decrease in the number of cancers with the GG risk genotype and subsequent loss of GG association with higher tumor grade and proliferation index in cancers. Furthermore, PVT1 expression was increased in cancers, and the increase was associated with the GG genotype of rs13281615. These results suggest that the GG genotype of SNP rs13281615 plays a role in breast cancer likely by influencing PVT1 expression, and that during oncogenesis, ＂protective＂ mutations could occur.
