Intermittent Hormone Therapy Models Analysis and Bayesian Model Comparison for Prostate Cancer.

Bulletin of mathematical biology

Pasetto S, Enderling H, Gatenby RA, Brady-Nicholls R.
PMID: 34797430
Bull Math Biol. 2021 Nov 19;84(1):2. doi: 10.1007/s11538-021-00953-w.

The prostate is an exocrine gland of the male reproductive system dependent on androgens (testosterone and dihydrotestosterone) for development and maintenance. First-line therapy for prostate cancer includes androgen deprivation therapy (ADT), depriving both the normal and malignant prostate cells...

Nonclassical androgen and estrogen signaling is essential for normal spermatogenesis.

Seminars in cell & developmental biology

Cooke PS, Walker WH.
PMID: 34119408
Semin Cell Dev Biol. 2022 Jan;121:71-81. doi: 10.1016/j.semcdb.2021.05.032. Epub 2021 Jun 09.

Signaling by androgens through androgen receptor (AR) is essential to complete spermatogenesis in the testis. Similarly, loss of the main estrogen receptor, estrogen receptor 1 (ESR1; also known as ERα), results in male infertility, due in part to indirect...

Androgens in prostate cancer: A tale that never ends.

Cancer letters

Hou Z, Huang S, Li Z.
PMID: 34052327
Cancer Lett. 2021 Sep 28;516:1-12. doi: 10.1016/j.canlet.2021.04.010. Epub 2021 May 28.

Androgens play an essential role in prostate cancer. Clinical treatments that target steroidogenesis and the androgen receptor (AR) successfully postpone disease progression. Abiraterone and enzalutamide, the next-generation androgen receptor pathway inhibitors (ARPI), emphasize the function of the androgen-AR axis...

Androgen and Luteinizing Hormone Stimulate the Function of Rat Immature Leydig Cells Through Different Transcription Signals.

Frontiers in endocrinology

Li X, Zhu Q, Wen Z, Yuan K, Su Z, Wang Y, Zhong Y, Ge RS.
PMID: 33815270
Front Endocrinol (Lausanne). 2021 Mar 17;12:599149. doi: 10.3389/fendo.2021.599149. eCollection 2021.

The function of immature Leydig cells is regulated by hormones, such as androgen and luteinizing hormone (LH). However, the regulation of this process is still unclear. The objective of this study was to determine whether luteinizing hormone (LH) or...

Anti-androgen for myoepithelial tumor: a potent therapy yet a potential misleader.

Anti-cancer drugs

Hijab A, Taha T, Charas T, Bar-Sela G, Stein P, Agbarya A.
PMID: 34387605
Anticancer Drugs. 2021 Aug 11; doi: 10.1097/CAD.0000000000001175. Epub 2021 Aug 11.

Myoepithelial tumor is a rare form of cancer, mainly arising from the salivary glands and extremities. Due to its rarity, no formal treatment guidelines exist. Here we report a case of a male patient diagnosed with metastatic myoepithelial tumor...

Cutibacterium acnes: Much ado about maybe nothing much.

Experimental dermatology

van Steensel MAM, Goh BC.
PMID: 34009698
Exp Dermatol. 2021 Oct;30(10):1471-1476. doi: 10.1111/exd.14394. Epub 2021 Jun 09.

Cutibacterium acnes (also known as Propionibacterium acnes) has long been implicated in the pathogenesis of acne, inspiring both therapeutic and personal care approaches aiming to control the disease by controlling the bacterium. The purported association has made people with...

The Association Between Dietary Inflammatory Index and Sex Hormones Among Postmenopausal Women in the US.

Frontiers in endocrinology

Chen WY, Fu YP, Zhong W, Zhou M.
PMID: 35002960
Front Endocrinol (Lausanne). 2021 Dec 21;12:771565. doi: 10.3389/fendo.2021.771565. eCollection 2021.

AIMS: Diet has been found to have an important effect on sex hormones. The effect of diet-induced inflammation on sex hormones has not been studied in detail among women. Therefore, we aimed to investigate the association between energy-adjusted dietary...

Steroid-converting enzymes in human adipose tissues and fat deposition with a focus on AKR1C enzymes.

European review for medical and pharmacological sciences

Kiani AK, Mor M, Bernini A, Fulcheri E, Michelini S, Herbst KL, Buffelli F, Belgrado JP, Kaftalli J, Stuppia L, Dautaj A, Dhuli K, Guda T, Manara E, Maltese PE, Michelini S, Chiurazzi P, Paolacci S, Ceccarini MR, Beccari T, Bertelli M.
PMID: 34890031
Eur Rev Med Pharmacol Sci. 2021 Dec;25(1):23-32. doi: 10.26355/eurrev_202112_27330.

Adipocytes express various enzymes, such as aldo-keto reductases (AKR1C), 11β-hydroxysteroid dehydrogenase (11β-HSD), aromatase, 5α-reductases, 3β-HSD, and 17β-HSDs involved in steroid hormone metabolism in adipose tissues. Increased activity of AKR1C enzymes and their expression in mature adipocytes might indicate the...

Comprehensive sex steroid profiling in multiple tissues reveals novel insights in sex steroid distribution in male mice.

Endocrinology
