Biochem/physiol Actions

DAPT is a γ-secretase inhibitor and indirectly an inhibitor of Notch, a γ-secretase substrate. Other γ-secretase substrates include LDL receptor-related protein, E-cadherin and ErbB-4. As an inhibitor of γ-secretase, DAPT may be useful in the study of β-amyloid (Aβ) formation. DAPT has been shown to inhibit Notch signaling in studies of autoimmune and lymphoproliferative diseases, such as ALPS and lupus erythematosus (SLE), as well as in cancer cell growth, angiogenesis, and differentiation of human induced pluripotent stem cells (hIPSC).

What is Product D5942, DAPT soluble in?
DAPT is soluble in DMSO at approximately 18 mg/ml.
Are solutions of Product D5942, DAPT stable?
Sigma has not evaluated the solution stability of DAPT. However, in a study of cultured insect cells, DAPT inhibited γ-secretase activity for 12 hours, which is indicative of its stability in solution at a presumed 37 °C temperature. Pitsi, D., and Octave, J.N., Presenilin 1 stabilizes the C-terminal fragment of the amyloid precursor protein independently of γ-secretase activity. J. Biol. Chem., 279(24), 25333-25338 (2004).
Is Product D5942, DAPT, a reversible or irreversible inhibitor of beta secretase?
The literature indicates that in a treatment of PDAPP neuronal cultures with DAPT, removal of DAPT from the protocol restores amyloid precursor protein β production. This implies that DAPT may be a reversible inhibitor. Dovey, H.F., et al. Functional gamma-secretase inhibitors reduce beta-amyloid peptide levels in brain. J. Neurochem., 76(1), 173-181 (2001).

传统观点认为,癌症是环境或内部因素诱导正常细胞内的关键致癌基因和肿瘤抑制基因突变导致的一种疾病。当这些突变导致细胞向更原始、高度增殖状态转化,克隆扩张形成白血病或实体肿瘤时,就会出现癌症的临床表现1。然而,这种模式不能够完全解释许多肿瘤和转移瘤的长发育延迟,产生细胞去分化和细胞永生的起始诱导机制,或肿瘤本身内的细胞功能和表型多样性起源。过去十年中,越来越多的证据表明,恶性肿瘤起源于组织干细胞在突...
