    常规医疗中来那卡韦(lenacapavir)用于HIV暴露前预防的早期患者报告结局与计划持续用药研究

    一项多中心研究评估了在常规医疗中开始每半年一次来那卡韦(lenacapavir, LEN)HIV暴露前预防(PrEP)者的早期患者报告结局。减少给药频率带来的便利是启用LEN的主要动机,尽管注射部位反应常见但多为轻度,总体满意度较高;持续性结节和疼痛是患者对未来继续用药的主要顾虑。研究提示需以患者为中心的咨询和实施策略来优化长效PrEP的长期坚持。

    操纵Warburg效应:线粒体表达假单胞菌D-丙氨酸脱氢酶生成丙酮酸,减缓体外肿瘤细胞增殖

    研究者在细胞线粒体基质表达来自假单胞菌的D-丙氨酸脱氢酶,加入D-丙氨酸使肿瘤细胞线粒体内直接生成丙酮酸(Grubaw系统),恢复氧化代谢。该体外操作使患者来源黑色素瘤细胞等增殖减慢、DNA复制与增殖相关基因受抑;HeLa细胞反将线粒体内多余丙酮酸排出胞外,转运通路未知。研究证实肿瘤细胞得益于Warburg效应下的糖酵解转换,线粒体活动本身即可下调肿瘤细胞增殖。
