A method to find longevity-selected positions in the mammalian proteome. [PDF]

open access: yesPLoS ONE, 2012
Evolutionary theory suggests that the force of natural selection decreases with age. To explore the extent to which this prediction directly affects protein structure and function, we used multiple regression to find longevity-selected positions, defined

Analysis of anti-Mullerian hormone (AMH) and its receptor (AMHR2) genes in patients with persistent Mullerian duct syndrome [PDF]

open access: yes, 2012
Objective: To screen for mutations in AMH and AMHR2 genes in patients with persistent Mullerian duct syndrome (PMDS). Patients and method: Genomic DNA of eight patients with PMDS was obtained from peripheral blood leukocytes.

Identification of the sex-determining locus in grass puffer (Takifugu niphobles) provides evidence for sex-chromosome turnover in a subset of Takifugu species. [PDF]

open access: yesPLoS ONE, 2018
There is increasing evidence for frequent turnover in sex chromosomes in vertebrates. Yet experimental systems suitable for tracing the detailed process of turnover are rare.

Anti-Müllerian Hormone Regulation of Synaptic Transmission in the Hippocampus Requires MAPK Signaling and Kv4.2 Potassium Channel Activity

open access: yesFrontiers in Neuroscience, 2021
Anti-Müllerian hormone (AMH) is a paracrine factor generated peripherally by the gonads to regulate gonadal function in adult mammals. We recently reported that AMH and AMH-specific receptor Anti-Müllerian hormone receptor 2 (AMHR2) are expressed in the ...

Supplementary Material for: AMH and AMHR2 Involvement in Congenital Disorders of Sex Development

open access: yes, 2021
Anti-müllerian hormone (AMH) is 1 of the 2 testicular hormones involved in male development of the genitalia during fetal life. When the testes differentiate, AMH is secreted by Sertoli cells and binds to its specific receptor type II (AMHR2) on the ...

Effect of anti-müllerian hormone on the development and selection of ovarian follicle in hens

open access: yesPoultry Science, 2021
To elucidate the role of anti-müllerian hormone (AMH) in regulating the development of ovarian follicles in laying hens, the expressions of follicle-stimulating hormone receptor (FSHR), AMH receptor type 2 (AMHR2), steroidogenic-related genes ...

Surgical management and molecular diagnosis of persistent Müllerian duct syndrome in Chinese patients

open access: yesAsian Journal of Andrology, 2022
Persistent Müllerian duct syndrome (PMDS) is a rare clinically and genetically overlapping disorder caused by mutations in the anti-Müllerian hormone (AMH) gene or the anti-Müllerian hormone receptor type 2 (AMHR2) gene.

Anti-Müllerian Hormone Signal Transduction involved in Müllerian Duct Regression

open access: yesFrontiers in Endocrinology, 2022
Over seventy years ago it was proposed that the fetal testis produces a hormone distinct from testosterone that is required for complete male sexual development.

Wanxi White goose and Yangzhou goose exhibited differences in the level of egg production, serum biochemical, hormones and related gene expression under the same natural photoperiod regulation

open access: yesJournal of Applied Animal Research, 2022
Egg production is seasonally regulated by the photoperiod in geese. To evaluate the effect of the natural photoperiod on egg production, 30 males and 120 females of 270-day-old Wanxi white geese and Yangzhou geese were selected and divided into two ...

Discovery of new receptors regulating luteinizing hormone and follicle-stimulating hormone secretion by bovine gonadotrophs to explore a new paradigm for mechanisms regulating reproduction

open access: yesThe Journal of Reproduction and Development, 2020
Previous studies in the 1960s and 1970s have reported that both gonadotropin-releasing hormone (GnRH) and estradiol-activated nuclear estrogen receptors regulate gonadotropin secretion in women.
