Functional Modules in Gametogenesis

open access: yesFrontiers in Cell and Developmental Biology, 2022
Gametogenesis, the production of eggs and sperm, is a fundamental process in sexually reproducing animals. Following gametogenesis commitment and sexual fate decision, germ cells undergo several developmental processes to halve their genomic size and ...

Plasmodium falciparum PP1 phosphatase is a key regulator of malaria parasite transmission [PDF]

open access: yesmBio
For the successful transmission of malaria parasites from humans to mosquitoes, Plasmodium falciparum gametocytes must remain in the bloodstream long enough to be taken up by a mosquito. Once ingested, they are then activated into gametes to continue the

Oxidative Stress Is Associated with Telomere Interaction Impairment and Chromatin Condensation Defects in Spermatozoa of Infertile Males

open access: yesAntioxidants, 2021
Telomere length can be influenced by reactive oxygen species (ROS) generated by lifestyle factors or environmental exposure. We sought to determine whether oxidative stress has an impact on sperm nuclear alterations, especially on chromatin organization ...

Annual variation in the levels of transcripts of sex-specific genes in the mantle of the common mussel, Mytilus edulis [PDF]

open access: yes, 2012
Mytilus species are used as sentinels for the assessment of environmental health but sex or stage in the reproduction cycle is rarely considered even though both parameters are likely to influence responses to pollution.

Knockout Serum Replacement as a Substitute for Exosome Free Serum

open access: yesTranslational Research in Urology, 2021
Exosomes, extracellular vesicles secreted from cells, are carriers containing proteins, lipids, and nucleic acids. By adhering and releasing their contents to the recipient cells, exosomes play a major role in cellular communication.

Effects of the exercise-inducible myokine irisin on proliferation and malignant properties of ovarian cancer cells through the HIF-1 α signaling pathway

open access: yesScientific Reports, 2023
Exercise has been shown to be associated with reduced risk and improving outcomes of several types of cancers. Irisin -a novel exercise-related myokine- has been proposed to exert beneficial effects in metabolic disorders including cancer.

The magnetic cell separation method reveals protective effect of melatonin on human spermatozoa from peroxide-induced apoptosis

open access: yesMiddle East Fertility Society Journal, 2023
Background The selection of non-apoptotic sperm is related to successful fertilization. This study investigated the protective effects of melatonin and the role of the MACS (magnetically activated cell sorting) method to prevent oxidative damage in vitro
