Patients with advanced hepatocellular carcinoma (HCC) will almost always develop acquired tolerance after sorafenib therapy, and the molecular mechanism of sorafenib tolerance remains poorly characterized. Here, using our established sorafenib-resistant HCC cell and xenograft models, we identified a novel gene, KIAA1199, which was markedly elevated among the differentially expressed genes involved in sorafenib tolerance. Moreover, elevated expression of KIAA1199 was positively correlated with a high risk of recurrence and metastasis and advanced TNM stage in HCC patients. Functionally, loss- and gain-of-function studies showed that KIAA1199 promoted the migration, invasion, and metastasis of sorafenib-resistant HCC cells. Mechanistically, KIAA1199 is required for EGF-induced epithelial-mesenchymal transition (EMT) in sorafenib-resistant HCC cells by aiding in EGFR phosphorylation. In summary, our data uncover KIAA1199 as a novel sorafenib-tolerant promoting gene that plays an indispensable role in maintaining sorafenib-resistant HCC cell metastasis.

An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.
An ORTHOHEPADNAVIRUS causing chronic liver disease and hepatocellular carcinoma in woodchucks. It closely resembles the human hepatitis B virus.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.
