Site‐Specific Mitochondrial RNA N1‐Methyladenosine Demethylation via an Engineered MTS‐PUF‐ALKBH3 Fusion Protein

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
A CRISPR‐free mitochondrial RNA m1A demethylation (MRD) editor combining MTS, PUF proteins, and ALKBH3 enables precise m1A removal from mitochondrial mRNA and tRNA, which influences mitochondrial protein levels, cellular proliferation, ATP production, and mitochondrial respiration. Subsequently, in vivo demethylation of the m1A modification is achieved

Oviductal extracellular matrix hydrogels enhance in vitro culture of rabbit embryos and reduce deficiencies during assisted reproductive technologies

open access: yesScientific Reports
In vitro embryo culture often falls short of mimicking the physiological dynamism occurring in the reproductive tract, prompting developmental plasticity in mammalian embryos with consequential genotypic and phenotypic deviations.

The Development of the Human Female Reproductive Tract. Part 1: Uterine Tube and Uterus

open access: yesClinical Anatomy, Volume 39, Issue 1, Page 92-111, January 2026.
ABSTRACT The uterine tubes and uterus develop from the paramesonephric (Müllerian) ducts. Most experimental data are obtained in rodents. Since the (micro‐)anatomy of the murine urogenital tract differs from that in humans, evaluation of the translatability of mouse data to human development is relevant.

Novel Worker‐Like Behavior Observed in Gynes of the Social Parasite Tetramorium microgyna

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Our article reports, to our knowledge, the first observations of inquiline gynes performing worker tasks for their host colony. We dissected these gynes to establish that they were all unmated. We hypothesize that nest excavation by social parasites represents an artifact of a non‐parasitic past.

The Effects of LeukemiaInhibitory Factor onDevelopment of MousePreimplantation Embryo

open access: yesArmaghane Danesh Bimonthly Journal, 2008
Introduction and Objective: Recent studies have demonstrated that mammalian preimplantation embryos are exposed to a mixture of many different growth factors and cytokines, expressed by the follicles, oviducts and endometrium.

Sterol Metabolism in Ovariectomized Rats: Potential Roles of Campesterol and 4β‐Hydroxycholesterol in Osteoporosis

open access: yesLipids, Volume 61, Issue 1, Page 151-162, January 2026.
ABSTRACT Osteoporosis is characterized by low bone mass and microarchitectural deterioration of bone tissue. Lipid metabolism disorders may contribute to osteoporosis in postmenopausal women. Phytosterols and oxysterols (OC) are involved in lipid metabolism.

Structure of the disulfide‐rich modules of a striking tandem repeat protein, avian cysteine‐rich eggshell membrane protein

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract Avian eggshell membrane (ESM) is fabricated within the isthmus region of the oviduct and is comprised of three juxtaposed, predominantly proteinaceous layers lying between egg white and the calcified shell. The limiting membrane is less than 0.5 μm in thickness and forms the osmotic barrier for the egg. This first layer provides the foundation

The Three Pillars of ATP Production in Mammalian Sperm: Integrating Gluconeogenesis Into the Metabolic Framework

open access: yesReproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose Mammalian sperm require a large amount of ATP to sustain motility. While glycolysis and oxidative phosphorylation (OXPHOS) are established ATP sources, they cannot fully explain motility maintenance under glucose‐deprived conditions.

Development of the internal reproductive organs in early nymphal stages of Archegozetes longisetosus Aoki (Acari, Oribatida, Trhypochthoniidae) as obtained by synchrotron X-ray microtomography (SR-μCT) and transmission electron microscopy (TEM)

open access: yesSoil Organisms, 2012
We studied the development of the internal reproductive organs in juvenile stages of Archegozetes longisetosus. 3D-renderings of organs were obtained from synchrotron X-ray microtomography (SR- µCT).
