BACKGROUND
Breast carcinoma amplified sequence 1 (BCAS1), located in 20q13, is amplified and overexpressed in breast cancers. Even though BCAS1 is expected to be an oncogene candidate, its contribution to tumorigenesis and copy number status in other malignancies is not reported. To elucidate the role of BCAS1 in squamous cell carcinomas, we investigated the copy number status and expression level of BCAS1 in several squamous cell carcinoma cell lines, normal keratinocytes and primary tumors.
METHODS
We quantitated BCAS1 gene by real-time polymerase chain reaction (PCR). Expression level of BCAS1 was measured by real-time reverse transcription-PCR and immunoblot.
RESULTS
Seven (88%) of 8 squamous cell carcinoma cell lines showed copy number gain of BCAS1 with various degrees. BCAS1 gene in primary tumors (73%) also showed copy number gain. However, expression level did not show a linear correlation with copy number changes.
CONCLUSIONS
We identified copy number gain of BCAS1 in squamous cell carcinomas. Due to lack of linear correlation between copy numbers of BCAS1 and its expression level, we could not confirm that the overexpression of BCAS1 is a common finding in squamous cell carcinoma cell lines. However, this study shows that the copy number gain of BCAS1 is a common finding in squamous cell carcinomas.

BACKGROUND
Osteoarthritis (OA) is a common disease characterized by degenerating joint cartilage in the knee, hip, and hand. A functional single nucleotide polymorphism (SNP) +104T/C; rs143383 in the 5' untranslated region of the growth differentiation factor 5 (GDF5) gene was recently associated with susceptibility to OA in the Japanese and Chinese populations.
METHODS
To investigate whether this association is present in the Korean population, the frequency of the polymorphism was investigated in 276 patients with knee OA and 298 healthy subjects as controls. Polymorphism analysis was performed by amplifying the core promoter region of the GDF5 gene and digesting it with the BsiEI restriction enzyme.
RESULTS
The frequency of the TT, CT, and CC genotypes was 54.3% (150/276), 41.7% (115/276), and 4.0% (11/276), respectively, in patients with OA, and 53.4% (159/298), 37.9% (113/298), and 8.7% (26/298), respectively, in healthy controls. No significant differences in genotypic or allelic frequencies of the +104T/C SNP of the GDF5 gene were observed between patients with OA and controls. Also, no significant differences in allelic and genotypic frequencies were found when the individuals were stratified by age and gender.
CONCLUSIONS
The results suggest that the +104T/C; rs143383 GDF5 core promoter polymorphism is not a risk factor for OA in the Korean population.

Abstract PDF: BACKGROUND
Several lines of evidence have indicated that the deregulation of apoptosis is involved in the mechanisms of cancer development, and somatic mutations of the apoptosisrelated genes have been reported in human cancers. Members of the bcl-2 family proteins regulate the intrinsic apoptosis pathway mainly in the mitochondria. The aim of this study was to explore whether the somatic mutation of the proapoptotic bcl-2 family genes, one of the mechanisms that prolong the survival of cancer cells, occurred in colorectal carcinomas.
METHODS
In the current study, to detect the somatic mutations in the DNA sequences encoding the bcl-2 homology 3 (BH3) domain of the human bak, bid, bik, bim, PUMA, bcl-rambo, bcl-G, and bmf genes in 98 colon adenocarcinomas, we used polymerase chain reaction (PCR), single strand conformation polymorphism (SSCP), and DNA sequencing.
RESULTS
The SSCP analysis detected no evidence of somatic mutations of the genes in the coding regions of the BH3 domain in the cancers.
CONCLUSIONS
The data presented here indicate that the proapoptotic bcl-2 family genes, bak, bid, bik, bim, PUMA, bcl-rambo, bcl-G and bmf may not be somatically mutated in human colorectal carcinomas, and suggest that the colorectal cancers may not utilize mutational events of these proapoptotic bcl-2 family genes in the mechanisms for evading apoptosis.

Abstract PDF: BACKGROUND
There are significant differences in the clincopathologic pattern including the incidence, favor site, and histopathologic type between cutaneous malignant melanomas arising from whites, asians and blacks. These differences might suggest that there is a racial difference in the molecular tumorigenesis mechanism of malignant melanoma.
METHODS
To determine the ethnic differences in tumorigenesis of malignant melanoma, we performed loss of heterozygosity (LOH) and sequencing analyses of the p53 gene in cutaneous malignant melanomas arising from 22 white American, 30 Korean and 15 black African patients.
RESULTS
The frequency of LOH of the p53 gene is only 12.5% in white American patients, but the frequency is significantly higher in Korean (42.1%) and black African (61.5%) patients. We also detected 17 mutations (nonsense: 1, missense: 16) of the p53 gene in the cutaneous malignant melanomas of Koreans and black Africans, but none in those of white Americans: among the 16 missense mutations, 10 mutations were C:G to T:A transitional mutations. Of these, we also detected one GG (CC) to AA (TT) tandem mutation at the pyrimidine sequence.
CONCLUSION
These results strongly suggest that there might be a racial difference in molecular carcinogenesis mechanisms among the cutaneous malignant melanomas occurring in white American, Korean and black African patients. But the role of the p53 genetic alteration in the genesis of melanomas in Korean and black African patients is subject to further evaluation.
