Implication

Demonstrates ANKRD49's role in promoting EMT in non-small cell lung cancer, indicating its potential as a therapeutic target.

Key Points

The study aims to explore the role of ANKRD49 in promoting epithelial-mesenchymal transition (EMT) in non-small cell lung cancer (NSCLC).
Analyzed ANKRD49 and EMT marker expression in LUAD tissues using TMAs and IHC.
Assessed the role of ANKRD49 in EMT through in vitro and in vivo experiments.
Performed real-time qPCR, Western blot, and ELISA for signaling molecule quantification.
Investigated transcriptional regulation of TGF-β1 by PKNOX1 using luciferase reporter assays and ChIP.
Examined protein-protein interactions via Co-IP and immunofluorescence.
Significant negative correlation between ANKRD49 and E-cadherin, and positive correlation with α-SMA and TGF-β1.
Overexpression of ANKRD49 promoted EMT; its knockdown suppressed EMT in both cellular and animal models.
ANKRD49 upregulation increased TGF-β1 levels, regulated by PKNOX1, with the opposite seen upon silencing ANKRD49.
ANKRD49 interacted with PKNOX1, leading to increased TGF-β1 expression and activation of SMAD signaling.
Positive correlation of ANKRD49 and PKNOX1 levels was observed in LUAD tissues.
