- 產(chǎn)品描述: Mirin是有效的Mre11–Rad50–Nbs1(MRN)復(fù)合體抑制劑,能夠抑制Mre11相關(guān)的外切酶活性。Mirin 可抑制MRN依賴的ATM的激活
- 靶點(diǎn): MRN;ATM;ATM/ATR
- 體外研究:
Mirin抑制了DSB誘導(dǎo)的ATM活化,ATM依賴性的下游靶點(diǎn)Nbs1和Chk2的磷酸化以及MRN依賴性的ATM在Ser1981位點(diǎn)的自磷酸化。Mirin還抑制了TOSA4細(xì)胞的G2檢查點(diǎn)以及HEK293細(xì)胞中同源依賴性的DNA修復(fù)。在整合有HPV16 (SiHa)的細(xì)胞中,Mirin增加了HPV episomes對(duì)PA25的敏感性,使PA25的IC50降低了5倍。mirin的預(yù)處理還降低了cisplatin處理的293細(xì)胞的細(xì)胞活性并且抑制了增殖細(xì)胞核抗原的表達(dá)
- 體內(nèi)研究:
Mirin in nanoparticles resulted in a sharp impairment of tumor growth, associated with DDR activation, p53 accumulation, and cell death.
- 細(xì)胞實(shí)驗(yàn): Cell lines: HEK 293 cells Concentrations: 100 μM Incubation Time: 24 h Method: 人源胚胎腎細(xì)胞HEK293用添加有5熱滅活胎牛血清,青霉素(100 U/mL),鏈霉素(100 mg/mL)的RPMI-1640培養(yǎng)基在含有5% CO2,37 °C的條件下進(jìn)行培養(yǎng)。每個(gè)48小時(shí)更換新的培養(yǎng)基。細(xì)胞接種到96-孔板上,用mirin(100 μM)預(yù)處理一小時(shí),然后加入cisplatin后再孵育8小時(shí)和24小時(shí)。然后利用EZ-Cytox cell viability assay kit進(jìn)行MTT測(cè)試,MTT的降低值用酶標(biāo)儀在450 nm波長(zhǎng)下進(jìn)行測(cè)定。
