Background:
In recent years, the incidence of thyroid cancer (TC), the most common endocrine malignancy, has been increasing. Emerging evidence indicates that the CUT/CUX/CDP family of proteins can play an important role in tumor development and progression by regulating many cancer-related functions. However, the molecular functions of CUX2 in TC remain unknown.
Methods:
In this study, we used a series of loss-of-function experiments and Western blot analysis to investigate the function of CUX2 in TC and the mechanisms involved.
Results:
Our data revealed that CUX2 expression levels were upregulated in papillary thyroid cancer (PTC). Functionally, CUX2 silencing significantly inhibited PTC cell line (KTC-1 and BCPAP) proliferation, colony formation, migration, invasion, and apoptosis. Furthermore, CUX2 induced epithelial-mesenchymal transition (EMT) and influenced the phosphorylation of AKT and mTOR in the PI3K-AKT-mTOR pathways.
Conclusion:
In summary, CUX2 may function as a tumor promoter in TC.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...
