(In Vitro)

M344 是一種潛在的組蛋白脫乙酰酶 (HDAC) 抑制劑。隨著 M344 濃度的增加,BRCA1 mRNA 出現(xiàn)劑量依賴性降低,并且使用 1 μM 和 5 μM 濃度的 M344 處理導(dǎo)致所有檢查的細(xì)胞系中 BRCA1 表達(dá)顯著降低。與順鉑單獨(dú)處理相比,M344 與順鉑聯(lián)合導(dǎo)致所有細(xì)胞系中 BRCA1 mRNA 表達(dá)降低,A2780s 除外,A2780s 被認(rèn)為對(duì)順鉑具有強(qiáng)細(xì)胞毒性。在 MCF7 細(xì)胞系中,BRCA1 在生理劑量的 M344 (0.5 μM 和 1 μM) 下調(diào),但 M344 在 5.0 μM 劑量下對(duì) BRCA1 沒有相同的抑制作用。在所有檢查的乳腺和卵巢細(xì)胞系中,與順鉑和增加濃度的 M344 聯(lián)合處理可降低 BRCA1 蛋白水平[2]。

Cell Assay
[2]

The A2780s and A2780cp cell lines, the T-47D and OVCAR-4 cell lines. and the MCF7 and HCC1937cell lines, are maintained in Dulbecco's-MEM supplemented with 10% fetal bovine serum and 100 μg/mL penicillin-streptomycin. Unless otherwise described, cells are treated for 24 hrs with 2 μg/mL Cisplatin alone, and in combination with the HDAC inhibitor M344 at concentrations of 0.5, 1.0, or 5.0 μM. Phase contrast images are collected using the 10× objective of an Eclipse TE2000-U. Cell viability is measured by the MTT rapid colorimetric assay. Approximately 4,500 cells are seeded into each well of a 96-well flat bottom plate. The cells are incubated overnight to allow for cell attachment. Cells are then treated with Cisplatin in concentrations of 0-8 μg/mL alone or in combination with 1 μM of the HDAC inhibitor, M344. Forty eight hours following treatment, 42 μL of a 5 mg/mL MTT substrate solution in phosphate buffered saline (PBS) is added and incubated for up to 4 hrs at 37°C. The resulting violet formazan precipitate is solubilized by the addition of 82 μL of a 0.01 M HCl/10% SDS solution and plates are incubated overnight at 37°C. The plates are then analyzed on an MRX Microplate Reader at 570 nm to determine the optical density of the samples[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
