Description

HUMAN CANCER SUPPRESSOR GENE, PROTEIN ENCODED THEREIN
TECHNICAL FIELD

The present invention relates to a human cancer suppressor gene, a protein encoded therein, an expression vector containing the same and a cell transformed with the vector.

BACKGROUND ART

Tumor suppressor gene products function to suppress normal cells from being transformed into certain cancer cells, and therefore loss of this function of the tumor suppressor gene products allows the normal cells to become malignant transformants (Klein, G., FASEB J, 7, 821-825 (1993)). In order to allow cancer cells to grow into a cancer, the cells should lose a function to control the normal copy number of a tumor suppressor gene. It was found that modification in a coding sequence of a p53 tumor suppressor gene is one of the most general genetic changes in the human cancers (Bishop, J.M., Cell, 64, 235-248 (1991); and Weinberg, R.A., Science, 254, (1991)).

However, it was estimated that only some of breast cancer tissues exhibit a p53 mutation because the p53 mutation reported in the breast cancer amounts to a range of 30 % of the total breast cancer (Keen, J.C. & Davidson, N. E., Cancer, 97, 825-(2003)) and Borresen-Dale, A-L., Human Mutation, 21, 292-300 (2003)). Also, it was estimated that only some of leukemia tissues exhibit a p53 mutation because the p53 mutation reported in the leukemia amounts to a range of 20 % of the total leukemia (Boyapati, A., et al., Acta Haematol., 111(1-2), 100-106 (2004)).

The p53 mutation accounts to at least 50 % of the liver cancer especially in the region exposed to aflatoxin B 1 or having a high frequency of infection by hepatitis B
virus, and it is mainly characterized by a missense mutation at a codon 249 in the p53 tumor gene (Montesano, R. et al., J. Natl. Cancer Inst., 89, 1844-1851 (1997);
Szymanska, K. & Hainaut, P. Acta Biochimica Polonica, 50, 231-238 (2003)).
However, it was reported that the p53 mutation amounts to nothing but a range of 30 %
of the liver cancer in U.S. and Western Europe, and there is no hot spot in which such mutation occurs frequently (Szymanska, K. & Hainaut, P. Acta Biochimica Polonica, 50, 231-238 (2003)).

Meanwhile, it was estimated that only some of the cervical cancer tissues exhibit a p53 mutation because the p53 mutation reported in the cervical cancer amounts to only a range of 2 to 11 % of the toatal cervical cancer (Crook, T. et al., Lancet, 339, 1070-1073 (1992); and Busby-Earle, R.M.C. et al., Br. j. Cancer, 69, 732-737 (1994)).

Also, it was reported that the mutation frequency of a p53 tumor suppressor gene in the non-small-cell lung cancer and the small-cell lung cancer amounts to approximately 50 % and 70 % of the total lung cancer, respectively (Takahashi, T. et al., Science, 246, 491-494 1989; Bodner, S.M. et al., Oncogene, 7, 743-749 (1992);
Mao, L.
Lung Cancer, 34, S27-S34 (2001)). Smoking is one of the most critical factors in development and progress of the lung cancer, and other various tumor suppressor genes and cancer genes in addition to the p53 are concurrently involved in the development and the progress of the lung cancer (Osada, H. & Takahashi, T. Oncogene, 21, 7421-7434 (2002)).

Accordingly, the present inventors have ardently attempted to separate a novel tumor suppressor gene from normal tissues such as breast, liver, cervix, lungs, etc. using an mRNA differential display (DD) method for more effectively displaying genes differentially expressed between the normal tissues such as the breast, the liver, the cervix and the lungs and the cancer tissues such as the breast cancer, the liver cancer, the cervical cancer and the lung cancer (Liang, P. and Pardee, A. B., Science, 257, 967-971 (1992); and Liang, P. et al., Cancer Res., 52, 6966-6968 (1993)).

The gene of the present invention is mainly overexpressed in these tissues as an mRNA transcript having a size of approximately 1.4 kb.

Meanwhile, because of degeneracy of codons, or considering preference of codons for living organisms to express the genes, the genes of the present invention may be variously modified in coding regions without changing an amino acid sequence of the protein expressed from the coding region, and also be variously modified or changed in a region except the coding region within a range that does not affect the gene expression.
Such a modified gene is also included in the scope of the present invention.

Accordingly, the present invention also includes polynucleotides having substantially the same DNA sequences as the above-mentioned genes; and fragments of the genes.
The term "substantially the same polynucleotide" means a DNA sequence having a sequence homology of at least 80 %, preferably at least 90 %, and the most preferably at least 95 %.

Also, one or more amino acids may be substituted, added or deleted even in the amino acid sequences of the proteins of the present invention within a range that does not affect functions of the proteins, and only some of the proteins may be used depending on their usage. Such a modified amino acid sequence is also included in the scope of the present invention. Accordingly, the present invention also includes polypeptides having substantially the same amino acid sequences as the proteins; and fragments thereof. The term "substantially the same polypeptide" means a polypeptide having sequence homology of at least 80 %, preferably at least 90 %, and the most preferably at least 95 %.

In some embodiments, the genes of the present invention prepared thus may be also inserted into a vector for expression in the microorganisms or animal cells, already known in the art, to obtain expression vectors, and then DNA of the genes may be replicated in a large quantity or its protein may be produced in a commercial quantity by introducing the expression vectors into suitable host cells, for example Escherichia coli, a MCF-7 cell line, etc. Upon constructing the expression vectors, expression regulatory sequences such as a promoter and a terminator, autonomously replicating sequences, secretion signals, etc. may be suitably selected and combined depending on kinds of the host cells that produce the genes or the proteins.

Especially, the genes of the present invention are differentially expressed only in the normal tissues. For example, their gene expressions are slightly detected or not detected in the cancer tissues and the cancer cells such as the breast cancer tissue, the breast cancer cell line MCF-7, the leukemia cell, the leukemia cell line K562, the liver cancer tissue, the liver cancer cell line HepG2, the cervical cancer tissue, the cervical cancer cell line, the lung cancer tissue, the metastatic lung cancer tissue and the lung cancer cell lines (A549 and NCI-H358), but differentially increased only in the normal uterine tissues.

The cancer cell lines introduced with the genes of the present invention showed a high mortality, and therefore the genes of the present invention may be effectively used for treatment and prevention of the cancer.

Hereinafter, the present invention will be described in detail referring to preferred examples. Therefore, the description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the invention.
