Abstract Over the past few years, the “epigenetic” regulation of the genome has become increasingly important to understanding both the etiology and fundamental mechanisms of aging and age-related diseases. Key to epigenetic regulation are two classes of lysine-modifying enzymes, the histone deacetylases (sirtuins and HDACs) and the histone acetyltransferases (HATs), also known as erasers and writers, respectively. Acetyl-lysine neutralizes the cationic charge relative to the naked Lys sidechain and also creates an attractive surface for binding to proteins containing bromodomains, also known as reader proteins. These acetyl-Lys writers, erasers, and readers are critical for maintaining normal expression patterns, cell cycle progression, DNA repair, stem cells, mitochondria, cell fate, and differentiation. Alterations in the functions of these acetyl-Lys related proteins have been linked to epigenetic silencing of gene expression including tumor suppressor genes, leading to cancer cell proliferation. Moreover, changes in acetyl-Lys pathways are believed to contribute to a variety of other diseases and aging mechanisms. Several broad spectrum HDAC inhibitors have been approved by FDA to treat various cancers. Their precise molecular mechanisms in controlling cancer and influencing other biomedical processes remain elusive. Although targeting HATs for therapeutic purposes has been relatively slow compared to targeting deacetylases, exciting new progress has also been made in recent years, including the recent discovery of A- 485 as a p300/CBP inhibitor. In addition, targeting bromodomains in cancer is a very active area. As the only conference dedicated to protein acetylation, this biannual meeting plays an essential role in bringing together more than 40 world leaders and ~120 participants. A primary objective is to transfer knowledge and foster collaboration between basic academic researchers, clinical scientists, and industrial researchers to understand how lysine acetylation controls human health and how to prevent and treat a diverse set of cancers and age-related diseases. A second objective is to foster the development and interests of younger investigators to help support their career development. The participants stay and eat at the meeting venue so they have ample time to for informal brainstorming and networking. There are 16 planned talks from junior scientists selected from the submitted abstracts, which is important for their career development. We will also have a panel discussion on professional development and career options, aimed to provide further support for the young investigators. Moreover, there will be a series of ask the experts discussion sections over lunch that will allow attendees to gain insight into specialized technologies (mass spectrometry, structural approaches, chemical biology methods, imaging strategies) that will be highlighted at the meeting. This meeting is particularly timely because of a linkage of acetylation, metabolism, and cancer. Furthermore, exciting new fundamental discoveries are continuing to be reported, such as the discovery of new lysine post-translational modifications (e.g. 3-hydroxybutyryl lysine and palmitoyl lysine) that can be removed by sirtuins or HDACs, and the discovery that these modifications can regulate transcription, cell signaling, and protein secretion. Therefore, support is requested for the 7th biannual FASEB conference on reversible protein acetylation in health and disease to be held in Lisbon, Portugal August 4 -9, 2019.

抽象的 在过去的几年中，基因组的“表观遗传”调节变得越来越重要 衰老和与年龄有关的疾病的病因和基本机制。表观遗传调节的关键是两个 赖氨酸改性酶的类别，Hisstone脱乙酰基酶（Sirtuins和HDACS）和Hisstone乙酰基转移酶 （帽子），也称为橡皮擦和作家。乙酰基赖氨酸中和阳离子相对于赤裸裸的 Lys Sidechain，还产生了一个吸引人的表面，用于与含有溴结构域的蛋白质结合，也称为 读取器蛋白质。这些乙酰透析作者，橡皮擦和读者对于维持正常表达模式至关重要， 细胞周期进程，DNA修复，干细胞，线粒体，细胞命运和分化。功能的改变 这些相关的乙酰透析蛋白与基因表达的表观遗传沉默有关，包括肿瘤抑制剂 基因，导致癌细胞增殖。此外，据信乙酰透析途径的变化有助于 其他各种疾病和衰老机制。 FDA已批准了几种广泛的HDAC抑制剂 治疗各种癌症。它们在控制癌症和影响其他生物医学方面的精确分子机制 过程仍然难以捉摸。尽管针对治疗目的的针对帽子与 靶向脱乙酰基酶，近年来也取得了令人兴奋的新进展，包括最近发现A- 485作为P300/CBP抑制剂。此外，癌症中靶向溴构域是一个非常活跃的区域。作为唯一的会议 这次双年展会议致力于蛋白质乙酰化，在汇集40多个世界中起着至关重要的作用 领导者和约120名参与者。一个主要目标是转移知识并促进基本之间的合作 学术研究人员，临床科学家和工业研究人员了解赖氨酸乙酰化如何控制人类 健康以及如何预防和治疗各种癌症和与年龄有关的疾病。第二个目标是促进 年轻调查人员的发展和利益，以帮助他们的职业发展。参与者留下来 在会议场所吃饭，因此他们有足够的时间去进行非正式的集思广益和网络。有16个计划 从提交的摘要中选出的初级科学家的会谈对他们的职业发展很重要。我们将 还就专业发展和职业选择进行小组讨论，旨在为 年轻的调查员。此外，将在午餐中进行一系列问候专家讨论部分，这将允许 与会者了解专业技术（质谱，结构方法，化学生物学 方法，成像策略）将在会议上强调。这次会议特别及时，因为 乙酰化，代谢和癌症的联系。此外，令人兴奋的新基本发现正在继续 报道了，例如发现新赖氨酸的翻译后修饰（例如3-羟基丁酰胺赖氨酸和棕榈酰基 赖氨酸）可以通过Sirtuins或HDAC去除，并且发现这些修饰可以调节转录， 细胞信号传导和蛋白质分泌。因此，请求支持第七次双年度FASEB会议的可逆会议 2019年8月4日至9日在葡萄牙里斯本举行的健康和疾病中的蛋白质乙酰化。
