Upregulated TC1 and downregulated Chibby were correlated with the aberrant β-catenin expression in laryngeal squamous cell carcinoma.

As an important member of Wnt/β-catenin signaling pathway, the aberrant expression of β-catenin has been implicated in many cancers. Chibby, a β-catenin binding partner, is an antagonist involved in this pathway. In contrast, thyroid cancer 1 (TC1) as an activator of this pathway can relieve the antagonistic activity of Chibby on the β-catenin-mediated transcription and is high expressed in human tumors.

STRIP2 motivates non-small cell lung cancer progression by modulating the TMBIM6 stability through IGF2BP3 dependent.

Background: Striatin interacting protein 2 (STRIP2) is a core component of the striatin-interacting phosphatase and kinase (STRIPAK) complexes, which is involved in tumor initiation and progression via the regulation of cell contractile and metastasis. However, the underlying molecular mechanisms of STRIP2 in non-small cell lung cancer (NSCLC) progression remain largely unknown.

Methods: The expressions of STRIP2 and IGF2BP3 in human NSCLC specimens and NSCLC cell lines were detected using quantitative RT-PCR, western blotting, and immunohistochemistry (IHC) analyses.

Overexpression of Laminin 52 Chain Correlates with Tumor Cell Proliferation, Invasion, and Poor Prognosis in Laryngeal Squamous Cell Carcinoma.

Objective: Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor. Laminin 52 chain (LAMC2) was reported to be associated with tumorigenesis. This study explored the role of LAMC2 on LSCC progression by regulating the integrin1/FAK/Src/AKT pathway.

KRT17 Accelerates Cell Proliferative and Invasive Potential of Laryngeal Squamous Cell Carcinoma (LSCC) through Regulating AKT/mTOR and Wnt/-Catenin Pathways.

Background: Laryngeal squamous cell carcinoma (LSCC) is a prevalent malignant tumor of the head and neck with a dismal prognosis. Keratin17 (KRT17) has been proven to serve as an oncogene in various cancers, but it has never been explored in LSCC. We proposed to assess the impact and possible mechanisms of KRT17 in the development of LSCC.

Pepsin and Laryngeal and Hypopharyngeal Carcinomas.

Laryngeal and hypopharyngeal carcinomas are common malignant tumors of the head and neck, and the incidence of both is increasing. Laryngopharyngeal reflux refers to the retrograde flow of gastric contents into the larynx, oropharynx, and/or nasopharynx. It remains controversial whether laryngopharyngeal reflux is a risk factor for laryngeal and hypopharyngeal cancers.
