TL;DR
This paper explores how integrin αvβ3 contributes to cholangiocarcinoma and suggests targeting it as a new treatment strategy.
Contribution
The study introduces a novel therapeutic strategy targeting integrin αvβ3 in cholangiocarcinoma.
Findings
Integrin αvβ3 interacts with EGFR and thyroid hormone to promote cholangiocarcinoma progression.
Lipo-tetrac and its Dox-derivative inhibit cancer cell growth in vitro and in animal models.
Thyroxine and EGF increase PD-L1 expression and influence cancer growth through different pathways.
Abstract
Cell surface receptors play vital roles in cancer growth and metastasis. Integrin αvβ3 is overexpressed in various cancer cells and interacts with different growth factors to stimulate cancer progression. Thyroid hormone binds to αvβ3 to activate signal transduction and cell proliferation. However, thyroxine (T4) deaminated analogue, tetraiodothyronine (tetrac), competes for the binding on integrin and inhibits cancer cell growth and metastasis. The current study investigated the pathogenic role of integrin αvβ3 and the potential of a novel therapeutic strategy targeted to integrin αvβ3. Pathogenetic studies of clinical samples revealed integrin αvβ3 cross-talked with EGFR and downstream signal transduction networks affected by thyroid hormone and EGF related to the progression of cholangiocarcinoma malignancy. Thyroxine and EGF stimulated PD-Ligand 1 (PD-L1) expression and cancer…
