常見問題列表

生物活性
Disitertide (P144) TFA 是轉(zhuǎn)化生長(zhǎng)因子 TGFβ1 的多肽抑制劑,特異性的阻斷其與受體間的相互作用。Disitertide (P144) 也是PI3K 的抑制劑和凋亡 (apoptosis) 誘導(dǎo)劑。
體外研究

Disitertide (100 μg/mL) suppresses the protein expression levels of PI3K and p-Akt, and induce the protein expression of Bax in MC3T3-E1 cells.
Disitertide (TGF-β1 inhibitor) abrogates the MACC1- AS1 expression in GC cells, suggesting that targeting TGFβ signaling pathway may be a potential strategy to inhibit MSC-induced stemness and chemoresistance.
Disitertide (P144, 10 μg/mL to 200 μg/mL) affects proliferation, induces apoptosis as well as anoikis in A172 and U-87 MG GBM cell lines.

Western Blot Analysis

Cell Line: Mouse embryo osteoblast precursor MC3T3-E1 cells.
Concentration: 100 μg/mL.
Incubation Time: 4 h.
Result: Significantly suppressed the protein expression levels of PI3K and p-Akt, and induce the protein expression of Bax in MC3T3-E1 cells compared with the miR-590 group.
體內(nèi)研究

Disitertide (Topical application, 300 μg/mL) may promote scar maturation and clinical improvement of hypertrophic scar morphology features in an “in vivo” model in nude mice after two weeks of treatment.

Animal Model: Human hypertrophic scars were implanted in 60 nude mice.
Dosage: 300 μg/mL was added the Lipogel.
Administration: Topical application daily administered.
Result: Successful shedding was achieved in 83,3% of the xenografts.
