Correlations between environmental salinity levels, blood biochemistry parameters, and steroid hormones in wild juvenile American alligators (Alligator mississippiensis).

Sci Rep 2021 Jul 26;11(1):15168. Epub 2021 Jul 26.

Department of Marine Biology, Texas A&M University At Galveston, Galveston Campus, 200 Seawolf Parkway, Bldg. 3029, Galveston, TX, 77553, USA.

American alligators (Alligator mississippiensis) inhabit freshwater wetlands that are vulnerable to salinization caused by anthropogenic alterations to freshwater flow, in addition to storm surges, sea level rise, and droughts. Salinization of coastal freshwater habitats is a growing concern in a changing climate due to increased frequency and intensity of storm surges and drought conditions. This study opportunistically sampled juvenile male and female wild alligators in various salinities each month excluding November, December, and January for one year at Rockefeller Wildlife Refuge in coastal Louisiana.

Let's Talk about Placental Sex, Baby: Understanding Mechanisms That Drive Female- and Male-Specific Fetal Growth and Developmental Outcomes.

Int J Mol Sci 2021 Jun 15;22(12). Epub 2021 Jun 15.

Mater Medical Research Institute, The University of Queensland, Brisbane, QLD 4000, Australia.

It is well understood that sex differences exist between females and males even before they are born. These sex-dependent differences may contribute to altered growth and developmental outcomes for the fetus. Based on our initial observations in the human placenta, we hypothesised that the male prioritises growth pathways in order to maximise growth through to adulthood, thereby ensuring the greatest chance of reproductive success.

Targeting Glucocorticoid Metabolism in Prostate Cancer.

Endocrinology 2021 Sep;162(9)

Genitourinary Malignancies Research Center, Lerner Research Institute, Cleveland Clinic, Cleveland, OH 44195, USA.

In the treatment of metastatic prostate cancer, resistance to hormonal therapy is a major obstacle. With antiandrogen therapies that suppress androgen signaling through the androgen receptor (AR), the primary driver of prostate cancer, some malignancies are able take advantage of the closely related glucocorticoid receptor (GR). Escape from AR dependency often involves a simple functional switch from 1 steroid receptor to another. Read More

Glucocorticoid-Mediated Changes in Male Green Treefrog Vocalizations Alter Attractiveness to Females.

Integr Comp Biol 2021 Jul;61(1):283-291

Department of Biology, University of Mississippi, Oxford, MS 38677, USA.

Adrenal glucocorticoids (GCs) are increasingly recognized as important modulators of male courtship signals, suggesting that circulating levels of these steroids can play a central role in sexual selection. However, few studies have examined whether GC-mediated effects on male sexual signals actually impact mate choice by females. Here, we examine how corticosterone (CORT)-mediated changes in the vocalizations of male green treefrogs, Dryophytes cinereus, influence attractiveness to females. Read More

Avian corticosteroid-binding globulin: biological function and regulatory mechanisms in physiological stress responses.

Front Zool 2021 Apr 29;18(1):22. Epub 2021 Apr 29.

Key Laboratory of Zoological Systematics and Evolution, Institute of Zoology, Chinese Academy of Sciences, Beijing, 100101, China.

Corticosteroid-binding globulin (CBG) is a high-affinity plasma protein that binds glucocorticoids (GCs) and regulates their biological activities. The structural and functional properties of CBG are crucial to understanding the biological actions of GCs in mediating stress responses and the underlying mechanisms. In response to stress, avian CBGs modulate the free and bound fractions of plasma corticosterone (CORT, the main GC), enabling them to mediate the physiological and behavioral responses that are fundamental for balancing the trade-off of energetic investment in reproduction, immunity, growth, metabolism and survival, including adaptations to extreme high-elevation or high-latitude environments.

Relationships between avian malaria resilience and corticosterone, testosterone and prolactin in a Hawaiian songbird.

Gen Comp Endocrinol 2021 Jul 20;308:113784. Epub 2021 Apr 20.

Department of Neurobiology, Physiology and Behavior, University of California Davis, One Shields Avenue, Davis, CA 95616, USA.

Glucocorticoids, androgens, and prolactin regulate metabolism and reproduction, but they also play critical roles in immunomodulation. Since the introduction of avian malaria to Hawaii a century ago, low elevation populations of the Hawaii Amakihi (Chlorodrepanis virens) that have experienced strong selection by avian malaria have evolved increased resilience (the ability to recover from infection), while high elevation populations that have undergone weak selection remain less resilient. We investigated how variation in malaria selection has affected corticosterone, testosterone, and prolactin hormone levels in Amakihi during the breeding season. Read More

Advances in technology are only beginning to reveal the complex interactions between hosts and their resident microbiota that have co-evolved over centuries. In this review, we present compelling evidence that implicates the host-associated microbiome in the generation of 11β-hydroxyandrostenedione, leading to the formation of potent 11-oxy-androgens. Microbial steroid-17,20-desmolase cleaves the side-chain of glucocorticoids (GC), including cortisol (and its derivatives of cortisone, 5α-dihydrocortisol, and also (allo)- 3α, 5α-tetrahydrocortisol, but not 3α-5β-tetrahydrocortisol) and drugs (prednisone and dexamethasone).

Hormonal Therapy for Prostate Cancer.

Endocr Rev 2021 May;42(3):354-373

Genitourinary Malignancies Research Center, Lerner Research Institute, Cleveland Clinic, Cleveland, OH, USA.

Huggins and Hodges demonstrated the therapeutic effect of gonadal testosterone deprivation in the 1940s and therefore firmly established the concept that prostate cancer is a highly androgen-dependent disease. Since that time, hormonal therapy has undergone iterative advancement, from the types of gonadal testosterone deprivation to modalities that block the generation of adrenal and other extragonadal androgens, to those that directly bind and inhibit the androgen receptor (AR). The clinical states of prostate cancer are the product of a superimposition of these therapies with nonmetastatic advanced prostate cancer, as well as frankly metastatic disease. Read More
