體外研究
(In Vitro)

5-Aminosalicylic acid (5-ASA) 是 PPARγ 的特異性激動(dòng)劑,只有 PPARγ 而非 PPARαPPARδ 能誘導(dǎo) p65 降解。5-Aminosalicylic acid 能誘導(dǎo) p65 蛋白降解,這表明 PPARγ 具有 E3 泛素連接酶活性。5-Aminosalicylic acid 還在 mRNA 水平上抑制 PAK1,這提示存在一種不依賴(lài)于 PPARγ 配體活化的額外機(jī)制。5-Aminosalicylic acid 通過(guò)抑制 PAK1 來(lái)阻斷腸上皮細(xì)胞 (IEC) 中的 NF-κB[1]。
用不同濃度 (10~1000 μmol/L) 的 5-Aminosalicylic acid 或尼美舒利預(yù)處理12~96 h,均呈劑量和時(shí)間依賴(lài)性抑制 HT-29 結(jié)腸癌細(xì)胞的生長(zhǎng),但 5-Aminosalicylic acid 或尼美舒利的抑制作用無(wú)統(tǒng)計(jì)學(xué)意義。不同劑量 5-Aminosalicylic acid 與尼美舒利聯(lián)合預(yù)處理 HT-29 結(jié)腸癌細(xì)胞,均呈劑量依賴(lài)性抑制生長(zhǎng)。5-Aminosalicylic acid (終濃度100 μM) 與尼美舒利 (終濃度10~1000 μM) 聯(lián)合用藥以劑量依賴(lài)性方式抑制 HT-29 結(jié)腸癌細(xì)胞的增殖,且其作用強(qiáng)度優(yōu)于相應(yīng)劑量的尼美舒利。同樣地,尼美舒利 (終濃度 100 μM) 和 5-Aminosalicylic acid (終濃度 10-1000 μM) 聯(lián)合使用也以劑量依賴(lài)性方式抑制這些細(xì)胞的增殖,并且比相應(yīng)劑量的 5-Aminosalicylic acid 更有效[2]

體內(nèi)研究
(In Vivo)

5-Aminosalicylic acid (5-ASA) 在異種移植腫瘤模型中具有抗腫瘤作用。為了評(píng)估 5-Aminosalicylic acid 的體內(nèi)抗腫瘤作用,將接種了 HT-29 結(jié)腸癌細(xì)胞的 SCID 小鼠連續(xù) 21 天每天接受 50 mM 的 5-Aminosalicylic acid 處理。處理結(jié)束時(shí),與對(duì)照小鼠或僅接受 GW9662 處理的小鼠相比,接受 5-Aminosalicylic acid 處理的 SCID 小鼠的腫瘤重量和體積減少了 80-86%。接受 5-Aminosalicylic acid 處理 10 天后,即可檢測(cè)到 5-Aminosalicylic acid 的抗腫瘤作用。接受 5 mM 的 5-Aminosalicylic acid 處理的小鼠也獲得了類(lèi)似的結(jié)果。通過(guò)同時(shí)腹膜內(nèi)注射 GW9662,5-Aminosalicylic acid 的抗腫瘤作用在 21 天時(shí)完全倍消除。因此,觀察到的 5-Aminosalicylic acid 的抗腫瘤作用至少部分依賴(lài)于 PPARγ[3]。

Cell Assay
[2]

Cytostatic effects are measured by MTT assay. HT-29 colon carcinoma cells are detached with a 0.25% trypsin solution for 5 min. Subsequently, the cells are seeded onto 96-well plates (1×106 cells/well), supplemented with 10% FCS and allowed to attach for 24 h before the addition of test compounds (5-Aminosalicylic acid 10, 50, 100, 500, and 1000 μM; Nimesulide; and their combination). Test compounds are diluted in serum-free culture medium. Then the cells are incubated in a medium or at different concentrations of drugs for 48 h, 20 μL of MTT solution (5 g/L) in PBS is added. Four hours later, the medium in each well is removed, and 120 μL of 0.04 mM muriatic isopropanol is added, slightly concussed for 10 min. Dye uptake is measured at 490 nm with an ELISA reader. Five wells are used for each concentration or as a control group. On the other hand, the cells are seeded onto 96-well plates (1×106 cells/well) and allowed to attach for 24 h, then treated with test compounds (5-Aminosalicylic acid, Nimesulide, and their combination). The final concentration is 100 μM. The same medium is added into the control group and dye uptake is then measured. Five wells are used for each test compound or control group[2].

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

Animal Administration
[3]

Mice[3]
Six to seven weeks old pathogen-free BALB/c SCID mice are used. Human colon cancer cells (107 HT-29 cells) pretreated or not with GW9662 for 24 h are implanted subcutaneously in the flank of animals. Two days after cell inoculation, mice are treated with 5-Aminosalicylic acid (5 or 50 mM) administered daily by peritumoral injection for 10 or 21 days. The effect of PPARγ during 5-Aminosalicylic acid treatment is evaluated by daily intraperitoneal injection of GW9662 (1 mg/kg/day). The control group receives saline instead of 5-Aminosalicylic acid. Mice are checked three times a week for tumor development. After killing at 10 or 21 days, tumor size and volume are calculated. Tumors are weighted before paraffin embedding for histological examination.

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.
