Journal ArticleDOI

Noboru Konishi,Mitsutoshi Nakamura,Shingo Nakaoka,Yoshio Hiasa,Masaki Cho,Hirotsugu Uemura,Yoshihiko Hirao,Takashi Muramatsu,Kenji Kadomatsu +8 more
TL;DR: In sections of whole prostate, MK showed variable expression through tumorous sections, probably in reflection of heterogeneous cell populations, which demonstrates the possible value of MK as a marker for early and latent disease, as well as for more advanced clinical stages of prostate cancer.
Journal ArticleDOI
Expression of nm23-H1 and nm23-H2 proteins in prostate carcinoma.
Noboru Konishi,Shingo Nakaoka,Toshihide Tsuzuki,Kyoichi Matsumoto,Yoshiteru Kitahori,Yoshio Hiasa,Takeshi Urano,Hiroshi Shiku +7 more
TL;DR: The data suggest that the nm23/NDP kinase may play a role in suppressing the expression of malignant potential in prostate carcinomas.
Journal ArticleDOI
Immunohistochemical Analysis of Estrogen Receptors in 313 Paraffin Section Cases of Human Thyroid Tissue
Yoshio Hiasa,Hiroto Nishioka,Yoshiteru Kitahori,Katsunari Yane,Shingo Nakaoka,Masato Ohshima,Noboru Konishi,Kiyoharu Nishii,Motokazu Kitamura,Takashi Matsunaga +9 more
TL;DR: It was suggested that ER expression may be related to prognosis and tumor growth at early stage and the observed sex differences regarding thyroid tumor incidence may reflect the higher estrogen serum content in females.
Journal ArticleDOI
Immunohistochemical Evaluation of Estrogen Receptor Status in Benign Prostatic Hypertrophy and in Prostate Carcinoma and the Relationship to Efficacy of Endocrine Therapy
Noboru Konishi,Shingo Nakaoka,Yoshio Hiasa,Yoshiteru Kitahori,Masato Ohshima,Shoji Samma,Eigoro Okajima +6 more
TL;DR: The levels of estrogen receptors in human benign prostatic hypertrophy and in various pathological classifications of prostate carcinoma were assessed and the prognosis for effective endocrine therapy was poor in cases where tissues demonstrated low or negative receptor levels.
Journal ArticleDOI
Relationships between serum thyroid stimulating hormone levels and development of thyroid tumors in rats treated with N-bis-(2-hydroxypropyl)nitrosamine.
Yoshio Hiasa,Yoshiteru Kitahori,Motokazu Kitamura,Hiroto Nishioka,Katsunari Yane,Mitsuru Fukumoto,Masato Ohshima,Shingo Nakaoka,Seiji Nishii +8 more
TL;DR: A sex difference in DHPN induction of thyroid tumor was shown for Wistar rats opposite to that reported to exist in humans, however, no clear relationship between dose of DHPN or incidence of thyroid tumors and serum TSH concentration was evident at the end of the experiment.
