Androgen receptor in serially subcultured human endometrial fibroblasts.

Specific dihydrotestosterone (DHT) binding was demonstrated in the whole cell sonicates obtained from serially subcultured human endometrial fibroblasts. This binding showed a high affinity and specificity for DHT (Kd=3.3 X 10(-10) M). Various kinds of excess nonradioactive steroids were arranged, as a result of competition among them, in the following decreasing order of binding affinity: DHT,...

Androgen receptor and intracrine androgen signaling in endometrial carcinomas

The androgen receptor (AR) is known to play critical roles in the malignancy of prostate cancer as well as the management of male reproductive organs. Endometrial carcinoma, one of the major female cancers, is considered an androgen-related cancer. However, the importance of androgen signaling through its receptor in endometrial carcinomas has not yet been clarified. We recently demonstrated th...

Cellular characterization and successful transfection of serially subcultured normal human esophageal keratinocytes.

BACKGROUND In vitro cell culture models can provide unique insights into squamous epithelial proliferation, differentiation, and neoplastic transformation. Cultures of human esophageal keratinocytes could be advantageous for the study of these processes. METHODS Normal human esophageal keratinocytes were cultivated on 3T3 fibroblast feeder layers in vitro and expanded through four serial subc...

Androgen receptor as potential therapeutic target in metastatic endometrial cancer

PURPOSE The expression and involvement of estrogen (ER) and progesterone receptor (PR) is extensively studied in endometrial cancer. Androgen receptor (AR) is a hormone receptor less studied in female cancers, and we here aim to investigate the expression level of AR in endometrial cancer precursor lesions, primary tumors and metastases, and its potential as therapeutic target. RESULTS Expres...

Gene transfer into subcultured endometrial cells using lipofection.

Lipofection using the Lipofectin reagent was optimized to transiently transfect subcultured guinea pig endometrial stromal cells with a beta-galactosidase gene driven by a simian virus 40 promoter. Efficient transfection was obtained in the following conditions: a value of six for the ratio of lipofectin to DNA, a low cellular density (10(5) cells per 35-mm well) at the time of subculture (48 h...
