Romidepsin(FK228,AbMole,M2007是一种去乙酰化酶HDAC抑制剂,主要作用于HDAC1和HDAC2,可通过表观遗传修饰调控基因表达。研究表明,Romidepsin(罗米地辛,CAS No.:128517-07-7)可通过诱导组蛋白超乙酰化(如H3K9Ac)显著增强特定基因的表达,例如脂肪生成相关基因(PPARγ、KLF15)和成骨相关基因(SP7/Osterix、ALP)等,从而促进细胞分化[1]。这种调控作用在骨髓间充质干细胞(BMSCs)中尤为明显,表现为脂肪细胞和成骨细胞分化能力的增强[1]Romidepsin(FK228,AbMole,M2007还可通过组蛋白乙酰化上调DNA损伤诱导转录因子4(DDIT4)的表达,进而抑制mTORC1信号通路,这一机制在食管鳞状细胞癌(ESCC)细胞系和小鼠异种移植模型(CDX模型)中得到了验证[2]。此外,Romidepsin(FR 901228)还能通过增加SOCS1表达并阻断STAT1/STAT3的激活,调控炎症相关信号通路[3]。其表观遗传修饰作用不仅限于癌症领域,在急性肾损伤(AKI)的小鼠(C57BL/6品系)模型中,Romidepsin通过上调H3乙酰化和减少CYP2E1表达,减轻了组织损伤[4]AbMole为全球科研客户提供高纯度、高生物活性的抑制剂、细胞因子、人源单抗、天然产物、荧光染料、多肽、靶点蛋白、化合物库、抗生素等科研试剂,全球大量文献专利引用

上海交通大学医学院瑞金医院、上海复旦大学华山医院的科研团队在该文章中揭示了HDAC3高表达与外周 T 细胞淋巴瘤(PTCL)的预后不良存在关联,抑制 HDAC3 可通过 ATF3 去乙酰化调控 CXCL12 分泌,招募并激活自然杀伤(NK)细胞,且与Doxorubicin联合使用可协同抑制 PTCL。在实验中,科研人员使用了由AbMole提供的多款产品,包括:Doxorubicin(阿霉素,Hydroxydaunorubicin,AbMole,M1969RGFP966(AbMole,M2977Romidepsin(FK228,AbMole,M2007。其中RGFP966(1357389-11-7)作为HDAC3的抑制剂,用于验证HDAC3可作为潜在的PTCL抑制靶点,而 Romidepsin(FK228,AbMole,M2007作为HDAC1/2的抑制剂,则作为对照组排除HDAC1/2对NK细胞依赖型抗瘤的作用,并用来对比HDAC3与HDAC1/2的功能差异[5]
HDAC3 is highly expressed in PTCL and targeting HDAC3 promotes infiltration of NK cells[5]
