Cynthia Kenyon (UCSF) Part 1: Genes that Control Aging
Once it was thought that aging was just a random and haphazard process. Instead, the rate of aging turns out to be subject to regulation by transcription factors that respond to hormones and other signals. In the nematode C. elegans, in which many key discoveries about aging were first made, the aging process is subject to regulation by food intake, sensory perception, and signals from the reproductive system. Changing genes and cells that affect aging can lengthen lifespan by six fold, and can also delay age-related disease, such as the growth of tumors.
控制衰老的基因电路
In the early 1990s, most scientists did not think that aging was subject to active regulation by the genes. Exciting results from Dr. Kenyon's lab, however, showed that a single mutation in the daf-2 gene caused the tiny roundworm C. elegans to live twice as long as normal. This gene encodes a hormone receptor that regulates lifespan not only in worms, but in flies, mammals and possibly humans as well.
寻找控制生长发育的基因
Eric Wieschaus and Christiane Nusslein-Volhard wanted to understand which genes regulated embryonic development in Drosophila. It took them 2 years to design their experiment and only a few months to execute. A combination of good design and good luck allowed them to start with 40,000 flies and identify just 139 genes necessary for embryonic development.
“抗体药物质量控制与检测分析研究” 空中讲坛
随着抗体药物研发进程的不断推动，抗体药物的适应症也逐渐扩大，从癌症、自身免疫病快速拓展到眼科疾病、高血脂、骨质疏松、哮喘、多发性硬化症等多个疾病领域，同时在抗病毒和细菌感染，心脑血管，糖尿病以及罕见病治疗等领域也发挥越来越重要的作用。为积极适应国家药品审评审批制度改革，充分发挥监管科学研究促进产业发展和服务监管决策的积极作用，生物谷与大家一起相聚云端，针对抗体药物质量控制与检测领域进行分析讨论，共话抗体药物质量控制与检测的相关研究进展！
细胞治疗合规性与工艺质量控制
目前，细胞治疗及其相关产业的正在快速发展，相关产品也陆续走向IND、临床试验的不同阶段。为规范如自体或异体的免疫细胞、干细胞、组织细胞或细胞系等产品的健康可持续发展，促进我国生物医药行业的健康有序发展，我国相关机构一直在快速完善相关法规与指导原则，以规范行业的健康稳定发展。2022年10月31日，国家药监局核查中心正式发布了《细胞治疗产品生产质量管理指南（试行）》，该指南从不同角度规范了细胞治疗的合规性与工艺质量控制要求。
细胞作为细胞治疗领域非常重要的载体，其安全、规范培养和研究一直是我国细胞治疗行业重点关注的内容。目前主要的细胞治疗方式为免疫细胞治疗和干细胞治疗。免疫细胞如T细胞、NK细胞、Car-T、Car-NK等细胞，其表现出杀伤肿瘤细胞、清除病毒等功能。干细胞凭借其多向分化、免疫调节以及分泌细胞因子等功能，也成为细胞治疗研究的核心领域之一，如间充质干细胞、造血干细胞、神经干细胞等。科研工作者可以借助生物培养箱、自动化细胞工作站、程序降温仪、液氮罐等设备实现实验室细胞规范培养和利用，为细胞治疗药物研发打下基础、提供便捷。
基于此，生物谷将联合青岛海尔生物医疗股份有限公司于2023年4月7日推出“细胞治疗合规性与工艺质量控制”主题空中讲坛，诚邀业内专家共同探讨实验室细胞培养和细胞治疗领域进展，希望能对行业内工作者带来帮助和启发。
