The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Genome-Wide Identification, Characterization, and Regulation of RWP-RK Gene Family in the Nitrogen-Fixing Clade

Plants, 2020
RWP-RK is a plant-specific family of transcription factors, involved in nitrate response, gametogenesis, and nodulation. However, genome-wide characterization, phylogeny, and the regulation of RWP-RK genes in the nodulating and non-nodulating plant ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

The subunit of RNA N6-methyladenosine methyltransferase OsFIP regulates early degeneration of microspores in rice.

PLoS Genetics, 2019
N6-Methyladenosine (m6A) RNA methylation plays important roles during development in different species. However, knowledge of m6A RNA methylation in monocots remains limited.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Effects of salinity on pollen germination in wild and cultivated leguminous species

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Plant sexual reproduction plays a crucial role in species persistence, land colonisation, and the enhancement of genetic diversity. Sexual reproduction in plants encompasses several key processes, including gametogenesis, fertilisation, zygote ...

A plant germline-specific integrator of sperm specification and cell cycle progression. [PDF]

PLoS Genetics, 2009
The unique double fertilisation mechanism in flowering plants depends upon a pair of functional sperm cells. During male gametogenesis, each haploid microspore undergoes an asymmetric division to produce a large, non-germline vegetative cell and a single

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, EarlyView.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...
