Mitochondrial Haplotype Shapes the Trajectory of Ovarian Aging in Genetically Heterogeneous Rats

Aging Cell, Volume 25, Issue 9, September 2026.
Using genetically heterogeneous rats carrying divergent mitochondrial haplotypes on a randomized nuclear background, we show that mtDNA variation modifies the rate of ovarian aging. OKC‐HETW ovaries showed bioenergetic deficits, reduced mtDNA copy number, and impaired TFAM–mtDNA binding by 4 months of age, with early fibrosis and immune infiltration ...

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

Andrology, Volume 14, Issue 6, Page 1647-1655, September 2026.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, Volume 14, Issue 6, Page 1757-1770, September 2026.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Reduced colony‐stimulating factor 1 receptor expression in myeloid cells has limited impact on chronic lymphocytic leukaemia progression

British Journal of Haematology, Volume 209, Issue 3, Page 939-952, September 2026.
Summary Targeting the colony‐stimulating factor 1 receptor (CSF1R) to remove tumour‐associated macrophages is being explored as cancer therapy. This strategy may be relevant for chronic lymphocytic leukaemia (CLL), which strongly depends on support from myeloid cells.

Extreme Cold Tolerance in a Calanoid Copepod Embryo From Antarctic Maritime Lakes Helps Explain Expansive Distribution in the Southern Hemisphere

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT The Antarctic copepod, Boeckella poppei, occurs in maritime freshwater lakes on sub‐Antarctic islands, Antarctic Islands and the Antarctic continent, but no previous studies assess the thermal tolerance behind this broad geographic distribution.
