In an attempt to identify tumor suppressor genes on chromosome 10 in non-small cell lungcancers, we isolated 10 types of splicing variants of the HELLS/ SMARCA6 gene transcripts.HELLS/SMARCA6 is a novel member of SNF2 family, which is implicated in cellular function like chromatin remodeling. Variant 1 was an alternatively spliced isoform containingan insertion of a 44-ntd intronic sequence between exons 3 and 4, giving rise to a prematuretermination of translation. The expression of the variant 1 was detected exclusively in thelung cancer specimens (11 of 43 cases, 26%), but was not detected in corresponding normal tissues. D10S520 marker in the proximity of the HELLS/SMARCA6 gene showed prevalent allelic loss (41%) as compared with flanking markers (25-31%). These results suggest that loss of function of HELLS/SMARCA6 by allelic loss and aberrant proteins by tumor-specific exon creation may result in epigenetic deregulation, leading the lung cells to malignancy or its progression.

Models for studying DNA methylation in human cancer: A review of current status

Shinichi Toyooka, Nobuyoshi Shimizu

Drug Discovery Today: Disease Models 1 ( 1 ) 37 - 42 2004年

記述言語：英語掲載種別：書評論文，書評，文献紹介等出版者・発行元：Elsevier Ltd

In cancer epigenetics, aberrant methylation in the promoter is one of the key mechanisms for gene inactivation resulting in carcinogenesis in humans. Unique models have been utilized for studying methylation, for example, to determine the methylation profile, to study the mechanisms of methylation, and to investigate therapeutic interventions against cancer In humans. It is considered that further development of would be highly useful for further understanding and controlling cancer in humans. © 2004 Elsevier Ltd. All rights reserved.

Background: The recently identified RASSF1 locus is located within a 120-kilobase region of chromosome 3p21.3 that frequently undergoes allele loss in lung and breast cancers. We explored the hypothesis that RASSF1 encodes a tumor suppressor gene for lung and breast cancers. Methods: We assessed expression of two RASSF1 gene products, RASSF1A and RASSF1C, and the methylation status of their respective promoters in 27 non-small-cell lung cancer (NSCLC) cell lines, in 107 resected NSCLCs, in 47 small-cell lung cancer (SCLC) cell lines, in 22 breast cancer cell lines, in 39 resected breast cancers, in 104 nonmalignant lung samples, and in three breast and lung epithelial cultures. We also transfected a lung cancer cell line that lacks RASSF1A expression with vectors containing RASSF1A complementary DNA to determine whether exogenous expression of RASSF1A would affect in vitro growth and in vivo tumorigenicity of this cell line. All statistical tests were two-sided. Results: RASSF1A messenger RNA was expressed in nonmalignant epithelial cultures but not in 100% of the SCLC, in 65% of the NSCLC, or in 60% of the breast cancer lines. By contrast, RASSF1C was expressed in all nonmalignant cell cultures and in nearly all cancer cell lines. RASSF1A promoter hypermethylation was detected in 100% of SCLC, in 63% of NSCLC, in 64% of breast cancer lines, in 30% of primary NSCLCs, and in 49% of primary breast tumors but in none of the nonmalignant lung tissues. RASSF1A promoter hypermethylation in resected NSCLCs was associated with impaired patient survival (P = .046). Exogenous expression of RASSF1A in a cell line lacking expression decreased in vitro colony formation and in vivo tumorigenicity. Conclusion: RASSF1A is a potential tumor suppressor gene that undergoes epigenetic inactivation in lung and breast cancers through hypermethylation of its promoter region.
