Research cited in this study

22 / 22 results

research Molecular Basis of Androgenetic Alopecia: From Androgen to Paracrine Mediators Through Dermal Papilla

122 citations , November 2010 in “Journal of Dermatological Science”

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

research Biosynthesis of Dihydrotestosterone by a Pathway That Does Not Require Testosterone as an Intermediate in the SZ95 Sebaceous Gland Cell Line

36 citations , October 2009 in “Journal of Investigative Dermatology”

This study suggests that in SZ95 sebocytes, a pathway for DHT biosynthesis does not require testosterone as an intermediate, potentially impacting the treatment of androgen-sensitive skin conditions.

research Sexual Hormones in Human Skin

305 citations , February 2007 in “Hormone and metabolic research”

This review discusses the roles of androgens and estrogens in skin functions and disorders, and highlights the use of estrogen-progestin treatments and anti-androgens in managing hirsutism and acne, without reporting new results.

65 citations , May 2006 in “Journal of Investigative Dermatology”

This study found that dexamethasone significantly reduced ERα mRNA levels and increased aromatase mRNA and activity in cultured human hair follicle dermal papilla cells, suggesting a glucocorticoid-dependent mechanism for estradiol action.

research Biology of Estrogens in Skin: Implications for Skin Aging

187 citations , December 2005 in “Experimental Dermatology”

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

research Substantial Sex-Dependent Differences in the Response of Human Scalp Hair Follicles to Estrogen Stimulation In Vitro Advocate Gender-Tailored Management of Female Versus Male Pattern Balding

38 citations , November 2005 in “Journal of Investigative Dermatology Symposium Proceedings”

research Hirsutism and the Variable Response of the Pilosebaceous Unit to Androgens

56 citations , August 2005 in “Journal of Investigative Dermatology Symposium Proceedings”

This review discusses the complex interaction between androgens and hair follicle biology, highlighting the need for a better understanding to improve hirsutism treatments, but reports no new results.

research Estrogens and the Skin

137 citations , June 2005 in “Climacteric”

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

research Gender Differences in Mouse Skin Morphology and Specific Effects of Sex Steroids and Dehydroepiandrosterone

168 citations , January 2005 in “Journal of Investigative Dermatology”

Male and female mice have different skin thickness, and hormones affect their skin and hair growth differently.

research Androgen Action on Human Skin – From Basic Research to Clinical Significance

147 citations , October 2004 in “Experimental dermatology”

This paper reviews the role of androgens in human skin function and the challenges in developing treatments for androgen-associated disorders, reporting no new experimental results.

research Acne and Sebaceous Gland Function

463 citations , September 2004 in “Clinics in dermatology”

This review discusses the development, function, and complex roles of sebaceous glands in acne and suggests future acne treatments should target inflammation and lipid production; it reports no new clinical results.

research Pathogenesis of Androgenetic Alopecia

52 citations , April 2004 in “Journal of The American Academy of Dermatology”

This article proposes three mechanisms by which dihydrotestosterone may contribute to baldness but reports no new research findings.

The Distribution of Estrogen Receptor Beta Is Distinct to That of Estrogen Receptor Alpha and the Androgen Receptor in Human Skin and the Pilosebaceous Unit

research The Distribution of Estrogen Receptor Beta Is Distinct to That of Estrogen Receptor Alpha and the Androgen Receptor in Human Skin and the Pilosebaceous Unit

130 citations , June 2003 in “Journal of Investigative Dermatology Symposium Proceedings”

This study found that estrogen receptor beta, not alpha, is the main mediator of estrogen action in human skin and hair follicles, suggesting a distinct role in these tissues.

research Androgenetic Alopecia in Women

139 citations , June 2003 in “Journal of Investigative Dermatology Symposium Proceedings”

This article reviews androgenetic alopecia in women, highlighting diagnosis criteria and noting that topical minoxidil is currently the only proven treatment for hair growth; it reports no clinical trial findings.

research Cutaneous Androgen Metabolism: Basic Research And Clinical Perspectives

233 citations , November 2002 in “The journal of investigative dermatology/Journal of investigative dermatology”

This review explores androgen metabolism in the skin, highlighting enzyme localization and potential implications for treating androgen-dependent skin conditions, but it reports no new clinical results.

research Androgen Receptor-Mediated Inhibition of Cutaneous Wound Healing

108 citations , September 2002 in “The Journal of clinical investigation/The journal of clinical investigation”

This study found that reducing testosterone levels in male mice accelerates wound healing and decreases inflammation, suggesting a potential therapeutic target for improving wound repair in elderly males.

research 17α-Estradiol Induces Aromatase Activity in Intact Human Anagen Hair Follicles Ex Vivo

94 citations , August 2002 in “Experimental Dermatology”

This study found that 17α‐estradiol increases aromatase activity in female hair follicles, which may explain its beneficial effects in treating androgenetic alopecia.

research Sebocytes Are the Key Regulators of Androgen Homeostasis in Human Skin

196 citations , May 2001 in “The journal of investigative dermatology/Journal of investigative dermatology”
