The study of tumor immunology has led to many innovative therapeutic strategies for the treatment of melanoma. The strategies are primarily dependent on melanoma-associated antigen peptide vaccination or T-cell-based therapy. These immunotherapies are totally reliant on proper copresentation of huma

โฆ Synopsis
Background and objectives:
We surveyed expression of melanoma antigen-encoding genes in lung cancer because of promising implications for immunotherapy.
Methods:
We studied 57 human lung carcinoma specimens using the reverse transcription-polymerase chain reaction (rt-pcr).
Results:
In the samples, the expression of melanoma antigen-encoding genes 1, 2, and 3 was observed in 9/43 (20.9%), 13/43 (30.2%), and 22/48 (45.8%), respectively. in 28 cases in which all three messenger rnas were sought, 18 (64.3%) showed expression of at least one gene, 10 (35.7%) showed expression of two or three genes, and 10 (35.7%) were negative for all three genes. in a clinicopathologic analysis, melanoma antigen-encoding genes 1 and 3 were frequently expressed in squamous cell carcinomas (p = 0.0543) and in cases with regional lymph node metastasis (p = 0.0572), respectively.
Conclusions:
The high incidence of melanoma antigen-encoding gene expression in lung cancer indicates the possibility of a future specific immunotherapy for this disease.

## Background: A human melanoma antigen-encoding gene-1, mage-1 gene, may be linked to the neoplastic transformation. in the present study, we extended this association with human gastric carcinomas. specifically, we focused on the relationship between mage-1 gene expression and the histologic stag
To confirm the ectopic production of human chorionic gonadotropin (hCG) in lung cancer, we attempted to detect the presence of mRNA transcripts of the alpha and beta genes for hCG in lung cancer tissues obtained from surgical operations. Although we were able to show the presence of hCG beta mRNA tr
Expression of HMGI(Y), a nucleoprotein that binds to A/T rich sequences in the minor groove of the DNA helix, is observable in neoplastically transformed cells but not in normal cells. We have analyzed HMGI(Y) expression in colorectal cancer and evaluated its clinicopathologic significance. HMGI(Y)
The present study was designed to clarify the mechanism by which some lung cancer cell lines can produce cytokeratin 19 (CK19) fragment and others cannot. We hypothesized that some lung cancer cell lines which cannot release CK19 express an incomplete sequence of CK19 mRNA. Expression of mRNA was ev
