Effects of Oestrogens and FSH on LH Stimulation of Steroid Production by Testis Leydig Cells from Immature Rats [PDF]

, 1978
Hypophysectomy of immature male rats results after 5 days in a decreased production of testosterone by isolated testis Leydig cells in response to LH. The LH responsiveness of the Leydig cells can be partly restored by treatment of the hypophysectomized ...

Antioxidant Capacity of Thyme (Thymus vulgaris) Essential Oil and Its Effect on In Vivo Fertility of Rams Subjected to Testicle Heat Stress

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 2, Page 437-448, March 2025.
ABSTRACT The detrimental effects of hyperthermia on the testes and the protective effect of thyme essential oil against testicular damage induced by this stress in rams were studied. Twenty‐four rams of the Barbarine breed with an average weight of 62.5 ± 0.3 kg and an average age of 24 ± 0.6 months.

Oestrogen suppresses the adipogenesis of fibro/adipogenic progenitors through reactivating the METTL3–ESR1‐mediated loop in post‐menopausal females

Clinical and Translational Medicine, Volume 15, Issue 2, February 2025.
Excessive muscular fatty infiltration in post‐menopausal women arose from the disruption of the methyltransferase‐like 3 (METTL3)–oestrogen receptor 1 (ESR1)‐mediated loop of fibro/adipogenic progenitors (FAPs) due to oestrogen deficiency. Reactivation of the METTL3–ESR1‐mediated loop by oestrogen alleviated excessive adipogenesis in FAPs, thereby ...

Signaling via retinoic acid receptors mediates decidual angiogenesis in mice and human stromal cell decidualization

The FASEB Journal, Volume 39, Issue 1, 15 January 2025.
Tightly regulated levels of retinoic acid, the physiologically active metabolite of vitamin A, are required for embryo implantation and pregnancy success. Our study shows that in vivo retinoic acid signaling is required for maintenance of the decidual vasculature that supports early pregnancy in mice, and signaling via retinoic acid receptor alpha is ...
