  • the cause and mechanism of the development of prostatic hypertrophy are not yet fully understood, but the reversal of sex hormones that occurs around the age of 40, that is, decreased secretion of the male hormone testosterone and adrenal glands. It is said that one of the causes is the proliferation of stromal components of the prostate, which is induced by an increase in the amount of estrogen, a female hormone produced.
  • dysuria caused by benign prostatic hyperplasia is largely due to the above-mentioned increase in benign adenomas in the internal glands, decreased elasticity of the prostatic capsule, and decreased bladder contractility (3). See, for example, Urol. Clin. North Am., 1990, Vol. 17, p. 509).

高齢者の割合が増加の一途とたどる我が国において、 男性高齢者の健 康的な生活を著しく損なう代表的な疾患は、 5 0歳代以上の男性におい て排尿障害を引き起こす原因となっている前立腺肥大症 ( Beni gn prostat ic hyperplas ia; BPH) と悪性腫瘍を伴う前立腺癌である。  In Japan, where the proportion of elderly people is ever increasing, a prominent disease that significantly impairs the healthy life of elderly men is the prostate gland that causes dysuria in men aged 50 and older. Prostate cancer with benign prostatic hyperplasia (BPH) and malignancy.
まず前立腺肥大症であるが、 前立腺肥大症の成因には、 遺伝的要因及 び食生活等の環境的要因など多数の要因が関与すると考えられるが、 未 だその全貌は明らかとされていない。 現在の我が国における前立腺肥大 症患者は厚生省による調査では 3 0乃至 4 0万人とされているが、 実際 には 4 0 0万人以上と推定されている。  First, prostatic hyperplasia is thought to be caused by a number of factors, including genetic factors and environmental factors such as diet, in the pathogenesis of prostatic hypertrophy, but the full picture has not yet been clarified. At present, the Ministry of Health and Welfare estimates that the number of patients with benign prostatic hyperplasia in Japan is 300,000 to 400,000, but it is actually estimated that it is over 400,000.
前立腺は若年期以後に発育増大しながら、 3 0歳代で正常の大きさで ある胡挑ほどの大きさに成長する。 しかしながら、 3 0歳代以降では、 前立腺の内腺部分に線維筋性の間質部分と腺性部分が混合した状態で肥 大した良性の腺腫が発生し、 この腺腫の増大化が即ち前立腺肥大症であ る (例えば、 J. Urol . , 1984, Vol. 132, p. 474- 479を参照)。 前立腺肥大症の発生頻度は、 3 0乃至 4 0歳代で約 7. 7%、 5 0歳代 で約 40%、 6 0歳代で約 67. 3%、 7 0歳代で約 92%、 8 0歳代では 100% であったとの報告がなされている(例えば、 Jap, J. Uro l . , 1967, Vol . 58, p. 814を参照)。 この発生頻度は、 欧米での報告とほぼ同様である。 この 良性腺腫の肥大に伴い、 7 5歳ではその約 50%において尿の勢いが弱く 、 なるという障害が生じる。 この前立腺肥大により、 8 0歳代ではその約 80%において、 何らかの排尿障害が生じる (例えば、 Prostate, 1990, Vol. 16, P253-261を参照)。 The prostate grows to a size similar to the normal size of Hu at the age of thirty, growing and growing after youth. However, from the age of thirties onwards, enlarged benign adenomas occur in the prostate inner glands with a mixture of fibromuscular stromal and glandular parts, and the adenomas are enlarged, that is, prostatic hyperplasia. With illness (See, for example, J. Urol., 1984, Vol. 132, p. 474-479). The incidence of benign prostatic hyperplasia is about 7.7% in the 30s to 40s, about 40% in the 50s, about 67.3% in the 60s, and about 92% in the 70s. In the 80s, it was reported that it was 100% (see, for example, Jap, J. Urol., 1967, Vol. 58, p. 814). The frequency of this occurrence is similar to that reported in Europe and the United States. With the enlargement of this benign adenoma, at the age of 75, about 50% of the urine has a weak urinary dysfunction. This enlargement of the prostate causes some dysuria in about 80% of those in their 80s (see, for example, Prostate, 1990, Vol. 16, pages 253-261).
上述したとおり、 前立腺肥大の原因と発生のメカニズムは未だ十分に は解明されていないが、 4 0歳.頃から起こる性ホルモンの逆転現象、 即 ち、 男性ホルモンのテス トステロンの分泌減少と副腎で産生される女性 ホルモンのエス トロゲンの分泌量の増加により誘導される前立腺の間質 成分の増殖がその原因の一つとも言われている。  As described above, the cause and mechanism of the development of prostatic hypertrophy are not yet fully understood, but the reversal of sex hormones that occurs around the age of 40, that is, decreased secretion of the male hormone testosterone and adrenal glands. It is said that one of the causes is the proliferation of stromal components of the prostate, which is induced by an increase in the amount of estrogen, a female hormone produced.
臨床症状的には、 前立腺肥大症により起こる排尿障害は、 上述した内 腺内に生じる良性腺腫の増大、 前立腺被膜の弾力性の低下、 及び膀胱収 縮力の低下の 3つが大きな成因である (例えば、 Urol. Cl in. North Am. , 1990, Vol. 17, p. 509を参照)。  Clinically, dysuria caused by benign prostatic hyperplasia is largely due to the above-mentioned increase in benign adenomas in the internal glands, decreased elasticity of the prostatic capsule, and decreased bladder contractility (3). See, for example, Urol. Clin. North Am., 1990, Vol. 17, p. 509).
従って、 今日における前立腺肥大症の治療は、 その発生の原因を遮断 することによるものではなく、 上述のような臨床症状を和らげるための 治療である。具体的には、腺腫の縮小を目的として抗アンドロゲン剤が、 前立腺被膜の弾力性の回復の目的で a i遮断剤 (α ιブロッカー剤) 力 また膀胱の収縮力の増強の目的で抗コリンエステラーゼ剤が用いられて いる。 Therefore, the treatment of benign prostatic hyperplasia today is not to block the cause of its occurrence, but to relieve the above-mentioned clinical symptoms. Specifically, anti-androgens are used to reduce adenomas, ai blockers ( α ι blockers) are used to restore the elasticity of the prostatic capsule, and anticholinesterases are used to increase bladder contractility. It is used.
しかしながら、 抗アンドロゲン剤では、 腺上皮の 30乃至 40%を縮小さ せるに過ぎず、 またその縮小効果と症状の改善の程度とは相関しない。 また抗アンドロゲン剤と a 1遮断剤との併用とその症状の改善効果も明 確ではない。 抗アンドロゲン剤での腺上皮の縮小効果が 30乃至 40%に過 ぎないという事実は、 前立腺肥大の発生の病因に上皮細胞 (epithelial cell) の増殖だけでなく、 間質細胞 (stroma cell ; ス トローマ細胞) の 増殖を伴う間質(ス トローマ)の増大があることを示唆するものである。 従って、 今後の前立腺肥大症の治療には間質を縮小させることが課題と されている (例えば、 薬局, 2000, Vol.51, No.3, p.29- 36を参照)。 しかしながら、 前立腺の肥大に到る前立腺の上皮細胞及び間質細胞の 増殖の原因及ぴメカニズムは未だ明らかにされていない。 However, antiandrogens only reduce 30-40% of the glandular epithelium, and do not correlate the reduction effect with the degree of symptom improvement. It is not clear how anti-androgens and a1 blockers are used in combination and their effects on amelioration of symptoms. The fact that the effect of antiandrogens on reducing the glandular epithelium by only 30 to 40% is attributed to the pathogenesis of prostatic hypertrophy as well as the proliferation of epithelial cells as well as stroma cells (stromal cells). This suggests that there is an increase in stroma (stroma) accompanying the proliferation of cells. Accordingly, there is a problem that reduces the interstitial to treat future prostatic hyperplasia (see, for example, pharmacy, 2000, Vol.51, No.3, the p.29- 3 6). However, the cause and mechanism of prostate epithelial and stromal cell proliferation leading to prostate hypertrophy has not yet been elucidated.
一方、 上述の前立腺肥大症と並んで男性高齢者において高い確立で発 症する前立腺癌は、 前立腺肥大症に見られる腫瘍が良性であるのに対し 前立腺癌におけるそれは悪性である点でさらに深刻な問題である。  On the other hand, prostate cancer, which develops with a high probability in elderly males along with the above-mentioned prostatic hyperplasia, is more serious in that it is malignant, whereas the tumor seen in benign prostatic hyperplasia is benign. It is a problem.
前立腺癌の死亡率は、 欧米に比べ低率ではあるものの、 日本において は前立腺癌による死亡率が他のどの癌によるそれにも比べ上昇してきて いるのは深刻な問題として捉えられている。 さらに興味深いことには、 剖検において発見される前立腺癌は致死癌の 1, 0 0 0倍以上であると いう事実である。 前立腺癌は初期の小さな悪性度の低い腫瘍細胞から大 きな悪性度の高い癌に変化してゆく速度が極めて遅い癌であるともいえ る。 8 0歳代の日本男子の実に 40%が前立腺癌を有している。  Although prostate cancer mortality is lower than in the United States and Europe, it is considered a serious problem in Japan that prostate cancer mortality is increasing compared to any other cancer. Even more interesting is the fact that prostate cancer found at necropsy is more than 1,000 times greater than lethal cancer. Prostate cancer can be said to be an extremely slow cancer that changes from small early low-grade tumor cells to large high-grade cancer cells. As many as 40% of Japanese boys in their 80s have prostate cancer.
このような一般的な前立腺癌に加えて、 最近、 前立腺組織の上皮内に 限定され細胞異型と腺細胞の多層化のみで診断される前立腺上皮内癌 (prostatic intraepithelial neoplasm; PIN) 力 s注目されてレヽる。 PIN を有する男性の約 50%は前立腺癌に進行しているという報告もなされ ている。 . In addition to this general prostate cancer, recently, prostatic intraepithelial carcinoma is limited to the epithelium of the prostate tissue is diagnosed in only multilayered cell atypia and glandular cells (prostatic intraepithelial neoplasm; PIN) force s attention has been Reply It has also been reported that about 50% of men with PIN have advanced prostate cancer. .
前立腺癌の臨床症状としては、 癌の増大による下部尿路症状;上部尿 路の通過障害; リンパ節、 肝臓または肺などへの転移に起因する症状 ; 骨転移による骨痛や神経圧迫による痛みなどがある。 The clinical symptoms of prostate cancer include lower urinary tract symptoms due to an increase in cancer; obstruction of the upper urinary tract; symptoms caused by metastasis to lymph nodes, liver or lungs; Pain due to bone metastasis or pain due to nerve compression.

上述した前立腺肥大の成因やそのメカニズムと同様に、 前立腺癌の発 生及ぴ進行のメカニズムについても未だ解明されておらず、 現在多くの 研究者らが様々な角度からその解明及びその予防及び治療が可能な薬剤 の開発に精力的な研究を進めている。  As with the causes and mechanisms of prostatic hyperplasia described above, the mechanisms of prostate cancer initiation and progression have not yet been elucidated, and many researchers are currently elucidating them from various angles and preventing and treating them. We are actively conducting research on the development of drugs that can be used.
そのような研究を進めるの一つのアプローチとして、 健常人の特定組 織や患者の該組織で特異的あるいは高い発現が見られる遺伝チを同定し、 当該遺伝子によりコードされる分子の生理活性を解析することにより当 該分子と疾患との関連性を明らかにするという手法がある。  One approach to pursue such research is to identify the genes that are specifically or highly expressed in specific tissues of healthy individuals or the tissues of patients, and analyze the biological activities of the molecules encoded by the genes. Then, there is a method of clarifying the relationship between the molecule and a disease.
前立腺肥大や前立腺癌の研究分野においても同様のアプローチが展開 されており、 前立腺肥大に罹患している患者の前立腺組織において多種 類の遺伝子の特異的発現が示唆されている (例えば、 国際公開第 0 2 / 1 2 4 4 0号パンフレッ トを参照)。また前立腺癌の患者の前立腺癌組織 に由来する細胞株あるいは当該癌組織においても例えば、 Cyr61 ( cysteine- ri ch 61) と呼ばれる分子の発現が認められることが報告さ れている (例えば、 Prostate, 1998, Vol . 36, No. 2, p. 85- 91 及び日本 泌尿器科学会雑誌, 2002, Vol . 93, No. 2, p. 31, PP- 335を参照)。  Similar approaches have been developed in the prostate hypertrophy and prostate cancer research areas, suggesting the differential expression of various genes in the prostate tissue of patients suffering from prostate hypertrophy (eg, International Publication No. 0 2/1 2 4 4 4 Refer to the pamphlet No.). It has also been reported that, for example, the expression of a molecule called Cyr61 (cysteine-rich 61) is also observed in a cell line derived from a prostate cancer tissue of a prostate cancer patient or in the cancer tissue (for example, Prostate, 1998, Vol. 36, No. 2, p. 85-91 and Japanese Journal of Urology, 2002, Vol. 93, No. 2, p. 31, PP-335).
しかしながら、 いずれの報告も、 前立腺肥大あるいは前立腺癌の組織 あるいはそれに由来する細胞株でのある種類の遺伝子の発現を開示する のみにとどまり、 当該遺伝子がコードする分子と前立腺肥大または前立 腺癌との関連性については何ら示唆及び開示されていない。  However, both reports only disclose the expression of certain genes in prostate hyperplasia or prostate cancer tissues or cell lines derived therefrom, and the genes encoded by the genes and prostate hyperplasia or prostate adenocarcinoma. There is no suggestion or disclosure of the relevance of

Also, these existing drug therapies do not suppress the growth of stromal cells (stromal cells), which are the direct cause of prostatic hypertrophy. In addition, the cause and mechanism of the occurrence and progression of prostate cancer in elderly men whose mortality rate has been increasing recently has not been clarified. No suppressive drug or radical treatment is provided. Disclosure of the invention
