The binding of LDN193189 to CD133 C-terminus suppresses the tumorigenesis and immune escape of liver tumor-initiating cells.
The tumor-initiating cell (TIC) marker CD133 promotes TIC self-renewal and tumorigenesis through the tyrosine phosphorylation of its c-terminal domain. Therefore, finding compounds that target the phosphorylation of CD133 will provide an effective method for inhibiting TICs characteristics. Here, through small molecule microarray screening, compound LDN193189 was found to bind to the c-terminus of CD133 and influenced its tyrosine phosphorylation. LDN193189 inhibited the interaction between CD133 and p85, accompanied by a reduction in the self-renewal and tumorigenicity of liver TIC. In addition, LDN193189 inhibited the expression and transcription of Galectin-3 by reducing the tyrosine phosphorylation of CD133. Galectin-3 secreted by liver TICs inhibited the proliferation of activated CD8 Topics: AC133 Antigen; Carcinogenesis; Cell Line, Tumor; Humans; Neoplastic Stem Cells; Pyrazoles; Pyrimidines; Tumor Escape | 2021 |
