    TCS 401 purchased from MedChemExpress. Usage Cited in: J Tissue Eng Regen Med. 2020 Apr;14(4):575-587.  [Abstract]

    The activation of Src by treatment with the 152RM peptide is reversed by pretreatment with the PTP1B inhibitor TCS-401, and the increased phosphorylation of β-catenin Y654 by treatment with the 152RM peptide is reduced by pretreatment with the Src inhibitor bosutinib.

    Description

    TCS 401 is a selective inhibitor of protein tyrosine phosphatase 1B (PTP1B).

    In Vitro

    TCS-401 (0.5, 1, 2 μM) significantly increases the proliferation of RPE cells. TCS-401 significantly increases the expression of cyclin A and cyclin D1 at the concentrations of 1 and 2 μM in a concentration-dependent manner. TCS-401 at concentrations of 0.5, 1, and 2 μM significantly increases phosphorylation of Erk and Akt compared to the control group. The activation of Erk and Akt by TCS-401 is blocked by pretreatment with PD98059 and LY294002, respectively. CS-401 treatment activates the MEK/Erk and PI3K/Akt signaling pathways and induces proliferation, differentiation, and migration in RPE cells[1]. CS-401 dose dependently inhibits the RPTC-Sup-induced reduction of fibronectin and α-SMA. At 1 μM, TCS-401 reverses the levels of fibronectin and α-SMA about onefold and at a dose of 2 μM, TCS-401 brings back fibronectin and α-SMA expression to near normal levels[2].

    Cell Assay
    [1]

    Cell proliferation are examined using MTT assay. The 5×103 cells grown in a 96-well plate for 24 h are partially starved in DMEM/F12 supplemented with 1% FBS for 12 h, and then stimulated with various concentrations of TCS-401 for an additional 24 h. MTT are added to the culture medium, and the cells are incubated for an additional 4 h. The formazan crystals formed are then dissolved by adding dimethyl sulfoxide (100 μL per well). Absorbance at 490 nm are measured using a microplate reader.

    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.
