Day length regulates gonadotrope proliferation and reproduction via an intra-pituitary pathway in the model vertebrate Oryzias latipes

open access: yesCommunications Biology
In seasonally breeding mammals and birds, the production of the hormones that regulate reproduction (gonadotropins) is controlled by a complex pituitary-brain-pituitary pathway.

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

open access: yes, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Generation of Neural Organoids and Their Application in Disease Modeling and Regenerative Medicine

open access: yesAdvanced Science, EarlyView.
Neural organoids provide a versatile platform for neurological research. Advances in organoid technology have partially achieved human neural tissue complexity in terms of tissue structure, cell diversity, and neural signaling, offering insights into neural disorders and regenerative strategies. Technology advances from biomaterials, bio‐manufacturing,

Use of kisspeptin to trigger oocyte maturation during in vitro fertilisation (IVF) treatment

open access: yesFrontiers in Endocrinology, 2022
Infertility is a major global health issue and is associated with significant psychological distress for afflicted couples. In vitro fertilisation (IVF) utilises supra-physiological doses of stimulatory hormones to induce the growth of multiple ovarian ...

RSPO2 Coordinates with GDF9:BMP15 Heterodimers to Promote Granulosa Cell and Oocyte Development in Mice

open access: yesAdvanced Science, EarlyView.
RSPO2 and GDF9:BMP15 heterodimers—core components of oocyte‐secreted factors (OSFs)—coordinate to shape the molecular architecture of preantral granulosa cells via gene‐specific synergistic and antagonistic regulation, mediated through CTNNB1–SMAD2 signaling crosstalk.

Experimental Study of the Effects of the Hypothalamic-Pituitary-Thyroid Axis on Platelet Functional Activity

open access: yesEuropean Journal of Inflammation, 2008
The hormones of the hypothalamic-pituitary-thyroid axis exert various effects in organism, but their influence on the functional activity of platelets is relatively unknown.

Pituitary Isograft Transplantation in Mice

open access: yesBio-Protocol, 2017
The mouse pituitary isograft is a technique developed to administer persistent hormone stimulation, thereby increasing cellular proliferation in the mammary tissue (Christov et al., 1993).

Pesticide Exposure Alters Follicle-Stimulating Hormone Levels in Mexican Agricultural Workers [PDF]

open access: yes, 2005
Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective

A Touch Enabled Hemodynamic and Metabolic Monitor

open access: yesAdvanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.
