Profile of gonadotropin secretion in male and female rats determined in the tail‐tip blood by ultrasensitive ELISA

Journal of Neuroendocrinology, Volume 38, Issue 3, March 2026.
Abstract There is a need for accurate and less invasive methods of hormonal measurements. Here, we longitudinally determined luteinizing hormone (LH) and follicle‐stimulating hormone (FSH) secretion measured in the tail‐tip blood of male and female rats by ultrasensitive enzyme‐linked immunosorbent assay (ELISA).

Time‐of‐Day Impacts Uterine Circadian Rhythms and Response to Oxytocin: Comparison of Uterine Function in Melatonin‐Deficient C57BL/6 Versus Melatonin Proficient CBA/B6 Hybrid Mice

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Reaching term gestation requires a complex interplay between the uterus and hormonal signals regulating its contractile profile. Most pregnancy‐associated hormones vary in their overall level of release throughout pregnancy, but also have a circadian release pattern, including progesterone, oxytocin, and melatonin. It remains poorly understood

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Sex differences in loop gain measured via superimposed end‐expiratory breath holds and inspired steady‐state hypoxia

Experimental Physiology, Volume 111, Issue 3, Page 1397-1412, 1 March 2026.
Abstract Acute low oxygen exposure (hypoxia) elicits a hypoxic ventilatory response (HVR), which increases ventilation and mitigates hypoxaemia. During sustained exposure to hypoxia, ventilatory acclimatization increases peripheral chemoreflex (HVR) sensitivity or chemoreflex loop gain (LG).

Maternal O‐GlcNAc Transferase Is Required for the Asymmetry of Epigenetic Modifications in Mouse Zygotes

The FASEB Journal, Volume 40, Issue 4, 28 February 2026.
OGT inhibition during in vitro oocyte maturation disrupts epigenetic asymmetry in the zygote. It reduces male pronuclear size and eliminates DNA methylation asymmetry by decreasing H3K9me2‐mediated 5mC protection in the female pronucleus and suppressing TET3‐dependent DNA demethylation in the male pronucleus.
