Oocyte analysis of species Arca noae Linnaeus, 1758 (Mollusca: Bivalvia) from Adriatic Sea
Noah’s ark shellfish is a commercially important species in the Adriatic Sea, but its populations are overexploited. The objective of this study was to complete the information on reproduction for potential commercial breeding.

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.

The ovulation assessment of regular cyclic rats following subacute oral administration of monosodium glutamate: An in vivo study [PDF]
Context: The possible toxic effects of monosodium glutamate (MSG) on ovarian functions have not been thoroughly evaluated in contrast to testicular functions. Few studies documented that MSG showed histological alterations.

Low Molecular Weight mRNA Encodes a Protein That Controls Serotonin 5-HT_(1c) and Acetylcholine M_1 Receptor Sensitivity in Xenopus Oocytes [PDF]
Serotonin 5-HT_(1c) and acetylcholine M_1 receptors activate phosphoinositidase, resulting in an increased formation of IP_3 and 1,2 diacylglycerol.

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

Genome‐wide, high‐resolution profiling of hydroxymethylation in mouse SCNT embryos reveals a transient, allele‐symmetric 5hmC reprogramming pattern distinct from natural embryos, with X‐chromosomes and imprinting control regions resistant to proper remodeling.
