The effect of L-carnitine in reactive oxygen species reduction and apoptotic gene expression in mice after cyclophosphamide: An experimental study

International Journal of Reproductive BioMedicine
Background: Cyclophosphamide (CP), a utilized anticancer drug, is known to cause infertility in women. However, L-carnitine (LC), an antioxidant, has been shown to offer protective benefits against infertility. Objective: This study aimed to evaluate the

Retinoblastoma and its binding partner MSI1 control imprinting in Arabidopsis. [PDF]

PLoS Biology, 2008
Parental genomic imprinting causes preferential expression of one of the two parental alleles. In mammals, differential sex-dependent deposition of silencing DNA methylation marks during gametogenesis initiates a new cycle of imprinting. Parental genomic

The life cycles of cryptogams [PDF]

, 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.

Epigenetic Modifications during Angiosperm Gametogenesis [PDF]

Frontiers in Plant Science, 2012
Angiosperms do not contain a distinct germline, but rather develop gametes from gametophyte initials that undergo cell division. These gametes contain cells that give rise to an endosperm and the embryo. DNA methylation is decreased in the vegetative nucleus (VN) and central cell nuclei (CCN) resulting in expression of transposable elements (TEs).

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

Environmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Piwi1 is essential for gametogenesis in mollusk Chlamys farreri [PDF]

PeerJ, 2017
Piwi (P-element induced wimpy testis) is an important gene involved in stem cell maintenance and gametogenesis in vertebrates. However, in most invertebrates, especially mollusks, the function of Piwi during gametogenesis remains largely unclear.

The Role of Diaphanous in Ring Canal Development in Drosophila melanogaster [PDF]

, 2016
Infertility is a widespread condition that does not always have a known cause, and for which we often do not have a cure. One potential cause of infertility is defects in gametogenesis, or the formation of sperm and egg.
