MDC9, also known as meltrin gamma, is a membrane-anchored metalloprotease. MDC9 contains several distinct protein domains: a signal sequence followed by a prodomain and a domain showing sequence… Expand
Conventional multiple or microdissection testicular sperm extraction: a comparative study.
- A. Tsujimura, K. Matsumiya, +7 authors A. Okuyama
- Biology, Medicine
- Human reproduction
- 1 November 2002
BACKGROUND
Testicular sperm extraction (TESE) with ICSI is becoming the first-line treatment for non-obstructive azoospermia (NOA). Recently, the sperm retrieval rate (SRR) by microdissection TESE… Expand

Prostate cancer often relapses during androgen-depletion therapy, even under conditions in which a drastic reduction of circulating androgens is observed. There is some evidence that androgens remain… Expand
Modulation of androgen receptor transactivation by gelsolin: a newly identified androgen receptor coregulator.

- 15 August 2003
The partial agonist effect of antiandrogens has been well documented, and such effect is amplified by derived mutant androgen receptors (ARs) in prostate cancer cells. Here we report the… Expand
Potential mechanism for the effects of dexamethasone on growth of androgen-independent prostate cancer.
- K. Nishimura, N. Nonomura, +11 authors A. Okuyama
- Biology, Medicine
- Journal of the National Cancer Institute
- 21 November 2001
BACKGROUND
Dexamethasone, a synthetic glucocorticoid, has clinical benefit in patients with hormone-refractory prostate cancer (HRPC), but the mechanisms responsible for its effects are unknown. The… Expand
