Gamete Formation Resets the Aging Clock in Yeast [PDF]

open access: yes, 2018
Gametogenesis is a process whereby a germ cell differentiates into haploid gametes. We found that, in budding yeast, replicatively aged cells remove age-induced cellular damage during gametogenesis.

Association of -308G/A TNFα gene polymorphism with reduced risk of idiopathic infertility in men

open access: yesFiyz̤, 2022
Background: Infertility is one of the major health problems in the world and several factors play a role in the occurrence of this complication. One of the causes of idiopathic male infertility is a defect in the process of spermatogenesis due to ...

Cold Thermal Priming of Laminaria digitata (Laminariales, Phaeophyceae) Gametophytes Enhances Gametogenesis and Thermal Performance of Sporophytes

open access: yesFrontiers in Marine Science, 2022
Thermal characteristics of kelp species have been studied in many ways, but potentially persistent effects of temperature across generations are yet poorly understood.

Developmental regulation of an organelle tether coordinates mitochondrial remodeling in meiosis. [PDF]

open access: yes, 2018
Cellular differentiation involves remodeling cellular architecture to transform one cell type to another. By investigating mitochondrial dynamics during meiotic differentiation in budding yeast, we sought to understand how organelle morphogenesis is ...

Long Non-Coding RNAs in the Control of Gametogenesis: Lessons from Fission Yeast

open access: yesNon-Coding RNA, 2021
Long non-coding RNAs (lncRNAs) contribute to cell fate decisions by modulating genome expression and stability. In the fission yeast Schizosaccharomyces pombe, the transition from mitosis to meiosis results in a marked remodeling of gene expression ...

Gonad variation and development of freshwater mussel Chambardia rubens Lamarck, 1819 (Bivalvia: Mutelidae) from the River Nile in Egypt [PDF]

open access: yesJournal of Bioscience and Applied Research, 2018
The gametogenesis, reproductive cycle, and larval morphology of Chambardia rubens (Bivalvia: Mutelidae) are studied for the first time in Egypt. A total of 46 mussels were collected seasonally from winter to autumn 2017 from Benha (Qaluobiya Governorate)

Birth seasonality studies in a large Prader-Willi syndrome cohort. [PDF]

open access: yes, 2019
Prader-Willi syndrome (PWS) is generally due to sporadic paternal deletions of the chromosome 15q11-q13 region followed by maternal disomy 15. Advanced maternal age is more commonly seen in those with maternal disomy 15. Environmental factors (e.g., drug

Duplicated membrane estrogen receptors in the European sea bass (Dicentrarchus labrax): Phylogeny, expression and regulation throughout the reproductive cycle [PDF]

open access: yes, 2018
The numerous estrogen functions reported across vertebrates have been classically explained by their binding to specific transcription factors, the nuclear estrogen receptors (ERs).

Plasmodium Condensin Core Subunits SMC2/SMC4 Mediate Atypical Mitosis and Are Essential for Parasite Proliferation and Transmission [PDF]

open access: yes, 2020
Condensin is a multi-subunit protein complex regulating chromosome condensation and segregation during cell division. In Plasmodium spp., the causative agent of malaria, cell division is atypical and the role of condensin is unclear.
