Definitions
- the present invention relates to a nucleic acid characterized by enhanced expression in a human neuroblastoma with a poor prognosis, as compared with a human neuroblastoma with a good and poor prognosis.
- Neuroblastoma is a childhood cancer that arises from sympathetic ganglion cells derived from peripheral sympathetic nervous system cells and adrenal medulla cells. These sympathetic nervous system cells are matured at the place where so-called sympathetic ganglia are formed when the neural crest cells in the early development migrate to the ventral side. Some of the cells migrate further into the adrenal gland, penetrate the adrenal cortex, which is being formed, and reach the medulla where they form the medulla. Neural crest cells are also the source of other peripheral nerve cells and differentiate into dorsal nerve ganglia (sensory nerves), skin pigment cells, thyroid C cells, some lung cells, and intestinal ganglion cells.
- Neuroblastomas are characterized by showing a variety of clinical features (Nakagawabara: Neuroblastoma occurrence and its molecular mechanism Pediatric Internal Medicine 30, 30). For example, neuroblastoma that begins before the age of one year has a very good prognosis, with most undergoing differentiation and cell death and regressing spontaneously. 6 months after birth, currently widely practiced Many neuroblastomas that are positive on urinary mass screening during this time are among those prone to this spontaneous regression. On the other hand, neuroblastomas that occur over the age of one year are highly malignant and often resist treatment and cause the child to die.

However, it is not limited to such a specific example.
- the nucleic acid of the present invention has been found from clinical tissue of human neuroblastoma, and has the following characteristics.
- Neuroblastoma is one of the two types of tumors of neurons known in humans.Analysis of the genes expressed in them is very important for understanding the biology of neuronal cells. It is thought to bring great knowledge to In other words, it is extremely difficult and practically impossible to obtain a site-specific homogeneous tissue from the brain and peripheral nerves. Neuroblastomas, on the other hand, consist of a nearly uniform population of neurons (albeit tumorigenic) derived from peripheral sympathetic neurons, and are likely to have uniformly expressed neuronal-related genes. Since neuroblastoma is a cancer, it is characterized by many important genes that are expressed at an immature stage of neurogenesis.
- neuroblastomas have a distinct clinical and biological distinction between those with good prognosis and those with poor prognosis.
- Cancer cells which are neuroblastomas with good prognosis, are characterized by a very slow growth rate and spontaneous regression at a certain point. Based on our findings, this spontaneous regression involves neuronal differentiation and apoptosis (neural cell death), a phenomenon very similar to the differentiation and programmed cell death that occur during the maturation stage of normal neurons. It turns out that it is. Therefore, analysis of the genes expressed in this tumor is important for neuronal differentiation and apoptosis. It is extremely likely that important information can be obtained.
- neuroblastomas with poor prognosis are tumors composed of cancer cells that continue to grow malignantly. Therefore, it is likely that there are many important genes related to the proliferation of nerve cells and many genes expressed in undifferentiated nerve cells. In other words, it is extremely likely that genetic information completely different from the profile of the gene expressed in neuroblastoma with a favorable prognosis will be obtained. It is generally said that neurons express more types of genes than cells derived from other organs.
- the neuroblastoma cell line (cell line) is derived from a clinical tissue with a poor prognosis, and it is considered that the gene expression profile is significantly different from that of normal neurons due to tumorigenesis.
- neuroblastoma is a child-derived tumor, and it is highly likely that the effects of acquired factors are very small. It is expected that it is likely to be possible. Furthermore, more surprisingly, the gene or gene fragment according to the present invention contains a gene that enhances expression only in a specific cell cycle. It is expected that very useful information on differentiation will likely be available.
- a nucleic acid having the above characteristics and from which the above information can be obtained is obtained from clinical tissue of human neuroblastoma, and has the nucleotide sequence of SEQ ID NOS: 1 to 69 in the sequence listing, or a partial nucleotide sequence of the nucleotide sequence.
