Purpose:
SCC-112 is a novel cell cycle-related gene and differentially expressed in cancers. Suggesting the complex role of SCC-112 might be existent in cell proliferation and tumor development. The relative research on SCC-112 has been few so far. This study is attempted to explore the role of SCC-112 in tumorigenesis.
Experimental Design:
RT-PCR and western blot were performed on seven tumor-normal paired tissues and nine cell lines. Immunohistochemistry was carried out for analyzing the expression of SCC-112 in nasopharyngeal tissues. 293T and three nasopharyngeal cell lines were transfected with expression vector (pCMV-SPORT6-SCC-112) or its siRNA. Cell proliferation was examined by MTT and clone formation experiments. Immunoprecipitation determined the interacted protein of SCC-112, and FACS detected cell cycle parameter on cells treated with synchronized reagent.
Results:
SCC-112 ( approximately 150 kDa) is up-regulated in tumor tissue as compared to the corresponding normal tissue and was detected in the tested cell lines. Overexpression of SCC-112 ( approximately 150 kDa) in 293T and three nasopharyngeal cell lines promoted cell proliferation and clone formation while downregulation of SCC-112 ( approximately 150 kDa) in these cells resulted in the opposite. Moreover, SCC-112 was found to interact with p63 and overexpression of SCC-112 up-regulated p63 expression. SCC-112 expression level positively correlated with cells in G2/M phase.
Conclusions:
These findings suggest that SCC-112 improve cell proliferation and contributes to tumorigenesis by interacting with p63 and promoting cell cycling. SCC-112 might be an alternative target in tumor biomarking and mechanistic investigation.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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.
