Protein Kinase C Regulates Meiosis in Mammalian Oocytes

open access: yesBioEssays, Volume 48, Issue 1, January 2026.
Protein kinase C (PKC) participates in the regulation of mammalian oocyte meiosis. PKC is involved in meiosis resumption in prophase I and in the stabilization of meiosis I and meiosis II spindles. PKC stimulates the maturation‐promoting factor during fertilization and stabilizes the mitotic spindle during early embryo development. ABSTRACT The protein

Translational repression by 4E-T is crucial to maintain the prophase-I arrest in vertebrate oocytes

open access: yesNature Communications
Meiotic maturation of vertebrate oocytes occurs in the near-absence of transcription. Thus, female fertility relies on timely translational activation of maternal transcripts stockpiled in full-grown prophase-I-arrested oocytes.

The life cycles of cryptogams [PDF]

open access: yes, 1991
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

Differential cohesin loading marks paired and unpaired regions of platypus sex chromosomes at prophase I

open access: yesScientific Reports, 2017
Cohesins are vital for chromosome organisation during meiosis and mitosis. In addition to the important function in sister chromatid cohesion, these complexes play key roles in meiotic recombination, DSB repair, homologous chromosome pairing and ...

Chromosome movement in meiosis I prophase of Caenorhabditis elegans

open access: yesChromosoma, 2013
Rapid chromosome movement during prophase of the first meiotic division has been observed in many organisms. It is generally concomitant with formation of the “meiotic chromosome bouquet,” a special chromosome configuration in which one or both ...

Add‐On Telitacicept Significantly Improves Outcome of Patients With Refractory Ocular Myasthenia Gravis a Real‐World Case Series

open access: yesBrain and Behavior, Volume 16, Issue 1, January 2026.
6/7 patients achieved CMI by the third follow‐up, sustained to the fourth follow‐up, and 4/6 reached MSE by the fifth follow‐up. First real‐world evidence of adding telitacicept efficacy in refractory ocular MG symptoms Abstract Introduction Refractory ocular myasthenia gravis (MG) represents a significant therapeutic challenge, as conventional ...

Plastids and mitochondria comportment in dividing meiocytes of Psilotum nudum

open access: yesActa Societatis Botanicorum Poloniae, 2014
In prophase I meiocyte plastids and mitochondria were situated at random. By telophase I plastids and mitochondria were aggregated in an equatorial plane.

Meiotic Cohesin SMC1β Provides Prophase I Centromeric Cohesion and Is Required for Multiple Synapsis-Associated Functions

open access: yesPLoS Genetics, 2013
Cohesin subunit SMC1β is specific and essential for meiosis. Previous studies showed functions of SMC1β in determining the axis-loop structure of synaptonemal complexes (SCs), in providing sister chromatid cohesion (SCC) in metaphase I and thereafter, in
