reference example 1

[0194] Reference Example 1. Cells

[0195] Human sebocyte cell line (SZ95) was cultured in Sebomed containing 10% FBS, 5ng / mL epidermal growth factor (EpidermalGrowth Factor) TM Cultured in basal medium (Biochrom). A human prostate cancer cell line (LNCaP) was cultured in RPMI1640 (Life technologies) containing 10% FBS. Usually, cultivation under oxygen concentration is carried out in air (oxygen concentration 20.9%). For culture under hypoxic conditions, AnaeroPack-Anaero 5% (Mitsubishi Gas Chemical Co., Ltd.) and an angled wide-mouth thermos flask (SUGIYAMA-GEN CO., LTD) were used in an oxygen concentration of 0.1%, 5% CO 2 and cultured at 37°C. SZ95 was supplied by Prof. Dr. Prof. h.c. Dr. h.c. Christos C. Zouboulis. LNCaP was purchased by ATCC.

[0197] (1) Androgen receptor gene

[0198] Using PrimeSTAR (registered trademark) GXL DNA Polymerase (Takara bio), the open reading frame (ORF) region of the gene encoding human androgen receptor (androgen receptor, AR) was amplified by PCR, followed by In-FusionHD Cloning Kit ( Takara Bio) was inserted into pcDNA3.1 (Lifetechnologies) treated with EcoRI. From Escherichia coli transformed with the plasmid DNA of interest, the plasmid DNA was purified using the EndoFree Plasmid Purification Kit (Qiagen). The purified plasmid DNA was named pcDNA3.1-AR.

[0199] (2) Glycolytic enzyme gene

[0200] Enolase 1, lactate dehydrogenase A, glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase 1, aldolase A, Insertion of the open reading frame (ORF) region of the genes for hexokinase 1, glucose-6-phosphate isomerase, and triosephosphate isomerase (ENO1, LDHA, GAPDH, PGK1, ALDOA, HK1, GPI, and TPI, respectively) to ...

Abstract

Provided is a method for searching for a substance capable of controlling the activity of an androgen receptor rapidly, with high accuracy and in a sebaceous-gland- and hair-follicle-selective manner, particularly a method for assessing or selecting a sebaceous-gland- or hair-follicle-selective androgen receptor activity controlling agent. The method comprises (A) applying a substance of interest to a sebaceous gland-originated cell or a hair follicle-originated cell under low-oxygen conditions; (B) measuring the activity of HIF1[alpha] in the cell; (C) comparing the activity measured in step (B) with the activity of HIF1[alpha] in a control group; and (D) assessing the HIF1[alpha] activity-controlling effect of the substance on the basis of the result obtained in step (C).

Description

technical field [0001] The present invention relates to a method for finding substances for selectively controlling the activity of androgen receptors of sebaceous glands or hair follicles. Background technique [0002] The androgen receptor (AR) is a receptor for steroid hormones including the mineralocorticoid receptor (MR), progesterone receptor (PR), estrogen receptor (ER), and glucocorticoid receptor (GR). Part of the body subfamily. Endogenous steroidal androgens (eg, testosterone and 5α-dihydrotestosterone (DHT)) are the major circulating sex hormones that play important roles in the regulation of various physiological processes in addition to promoting secondary sexual characteristics. Regarding the effect of androgens on the skin, oral administration of dehydroepiandrosterone (DHEA) has been reported to improve skin condition in the elderly; and topical administration of DHEA to the skin, usually in postmenopausal women with reduced sebum volume The amount of midd...
