Abstract

Previous studies have shown that there is a high frequency of loss of heterozygosity (LOH) on chromosome 17p13.3 in hepatocellular carcinoma [HCC (M. Fujimori et al., Cancer Res., 51: 89-93, 1991; H. Nagai et al., Oncogene, 14: 2927-2933, 1997; V. Boige et al., Cancer Res., 57: 1986-1990, 1997; Z. Piao et al., Int. J. Cancer, 75: 29-33, 1998; and B. Charroux et al., J. Cell Biol., 148: 1177-1186, 2000)]. The minimum region of LOH on chromosome 17p13.3 in HCC has been defined within the region between D17S643 and D17S1574. Moreover, D17S926 in the minimum region of LOH has the highest frequency of LOH, and its sequencing analysis has been accomplished. In this region, 6 of 13 novel genes have been characterized (X. Zhao, D. Wan, M. He, Yu. Ye, Yi. He, L. Han, M. Guo, Y. Huang, W. Qin, M-W. Wang, W. Chong, J. Chen, L. Zhang, N. Yang, B. Xu, M. Wu, L. Zuo, and J. Gu. A high frequency LOH region on chromosome 17p13.3 in human HCC with densely clustered genes identified, submitted for publication). Here we describe the cloning and characterization of one of these novel genes, designated HCC suppressor 1 (HCCS1), located at this region. HCCS1 had 18 exons, and its full-length cDNA was 2.0 kb. The protein expression product of HCCS1 w...Continue Reading
