Tectochrysin (Techtochrysin) 抑制 NF-κB 的活性。Tectochrysin (Techtochrysin) 直接與 p50 單元結(jié)合。Tectochrysin (Techtochrysin) 通過抑制 IκB 的磷酸化,濃度依賴性地抑制 p50 和 p65 轉(zhuǎn)運(yùn)到細(xì)胞核中。為了評估 Tectochrysin 對結(jié)腸癌細(xì)胞 (SW480、HCT116) 細(xì)胞生長的抑制作用,通過 MTT 測定法分析細(xì)胞活力。用不同濃度的 Tectochrysin (Techtochrysin)? (1,5,10 μg/mL) 處理細(xì)胞 24 小時(shí)。Tectochrysin (Techtochrysin) 以濃度依賴性方式抑制結(jié)腸癌細(xì)胞的細(xì)胞生長。Tectochrysin (Techtochrysin) 抑制 SW480 細(xì)胞生長,IC50 值為 6.3 μg/mL 和 HCT116 細(xì)胞生長,IC50 值為 8.4 μg/mL。形態(tài)學(xué)觀察表明,NSC 80687 (10 μg/mL) 處理 SW480 細(xì)胞和 HCT116 細(xì)胞后,細(xì)胞體積減小。然而,在通過 MTT 測定法檢測的濃度下,鳶尾黃素 (Techtochrysin) 在正常 CCD-18co 細(xì)胞中沒有細(xì)胞毒性。為了描述凋亡細(xì)胞死亡的誘導(dǎo)是否對 NSC 80687 的細(xì)胞生長抑制至關(guān)重要,使用 DAPI 染色評估細(xì)胞染色質(zhì)形態(tài)的變化。為了進(jìn)一步表征 Tectochrysin (Techtochrysin) 引起的凋亡細(xì)胞死亡,進(jìn)行了 TUNEL 染色測定,然后通過熒光顯微鏡分析標(biāo)記的細(xì)胞。SW480 細(xì)胞中的凋亡細(xì)胞數(shù) (DAPI 陽性 TUNEL 染色細(xì)胞) 在 0 和 10 μg/mL NSC 80687 的作用下分別增加到 1 和 58 %,在 HCT116 中通過 0 和 10 μg/mL Tectochrysin 分別增加到 1 和 54 %[1]。

體內(nèi)研究
(In Vivo)

為了闡明 Tectochrysin 在體內(nèi)的抗腫瘤作用,研究了 Tectochrysin (NSC 80687) 處理后結(jié)腸癌異種移植裸鼠的腫瘤生長情況。在 HCT116 異種移植物研究中,Tectochrysin (NSC 80687) 每周兩次腹膜內(nèi)給藥,持續(xù) 3 周,小鼠的腫瘤體積為 200 至 300 mm3。小鼠每周稱重兩次。在實(shí)驗(yàn)期間,對照組和 Tectochrysin (NSC 80687) 處理的小鼠 (n=10) 之間的體重變化沒有顯著差異。然而,在第 21 天,記錄了最終的腫瘤重量。用 5 mg/kg 劑量的 Tectochrysin (NSC 80687) 處理的小鼠的腫瘤重量和體積分別是載體組的 57.9% 和 46.4%[1]。

Cell Assay
[1]

Each SW480, HCT116, HT-29, A549 and MCF-7 cell line (1×104 cells) is incubated in 200 μL of RPMI 1640, DMEM medium with NSC 80687 (concentrations ranging from 1, 5, 10 μg/mL) in a 96-well flat-bottomed plate in triplicate. After incubation for 72 h at 37°C, MTT diluted in RPMI 1640, DMEM medium are added to each well and incubation is carried out for 90 min. The supernatant is then discarded and the crystal products are eluted with DMSO (200 μL/well). Colorimetric evaluation is performed with a spectrophotometer at 540 nm. The apoptosis assay is first performed by using DAPI staining. SW480 and HCT116 human colon cancer cells are cultured with concentrations of NSC 80687 (5 μg/mL), and induction of apoptotic cell death is evaluated after 24 h. Tunel assay is done[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Mice[1]
Five-week-old male BALB/c athymic nude mice (n=10/group) are used. HCT116 cancer cells are injected subcutaneously (1×107 cells/0.1 mL PBS/animal) into the lower right flanks of mice. After 14 days, when the tumors have reached an average volume of 200-300 mm3, the tumor-bearing nude mice are intraperitoneally injected with Tectochrysin (NSC 80687) (5 mg/kg dissolved in 0.1 % DMSO) twice per week for 3 weeks. The tumor volumes are measured with vernier calipers and calculated[1].

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.
