Environmental factors affect not only paternal condition but may translate into the following generations where sperm-mediated small RNAs (sRNAs) can contribute to the transmission of paternal effects. sRNAs play a key role in the male germ line in genome maintenance and repair, and particularly in response to environmental stress and the resulting...

Neural crest (NC) cells form a multipotent stem cell population specified during neurulation, which undergo an epithelial-to-mesenchymal transition (EMT) and migrate extensively in the developing embryo, to generate numerous tissues and cell types including the craniofacial skeleton, the peripheral nervous system and pigment cells. The genetic and...

Background Piwi-interacting RNAs (piRNA)s are non-coding small RNAs that post-transcriptionally affect gene expression and regulation. Through complementary seed region binding with transposable elements (TEs), piRNAs protect the genome from transposition. A tool to link piRNAs with complementary TE targets will improve our understanding of the rol...

One of the key processes that forms the basis of fertilisation is the tight interaction between sperm and egg. Both sperm and egg proteomes are known to evolve and diverge rapidly even between closely related species. Understanding the sperm proteome therefore provides key insights into the proteins that underpin the mechanisms involved during fert...

A new subpopulation of polar bears (Ursus maritimus) was recently discovered in the South-East of Greenland (SEG). This isolated colony inhabits a warmer climate zone, akin to the predicted future environments of polar bears with vastly reduced sea ice habitats, rendering this population of bears particularly important. Over two-thirds of polar bea...

PARAGRAPH Males produce millions of sperm in a single ejaculate, but only a single sperm fertilises the egg. Fertilisation is the perfect opportunity for natural selection where sperm of poor quality are eliminated, and the fittest sperm sire the offspring. However, the biomarkers of the fittest sperm are currently elusive. Here, we selected human...

Dietary fibres (DFs) constitute a wide range of heterogeneous compounds that resist digestion and have beneficial effects on general health. Gum Arabic (GA) is a tree exudate consisting of 90% arabinogalactan, a polymer of arabinose and galactose sugars with prebiotic properties. As a dietary fibre, GA improves renal function, metabolism, and immun...

Background Piwi-interacting RNAs (piRNA)s are non-coding small RNAs that post-transcriptionally affect gene expression and regulation. Through complementary seed region binding with transposable elements (TEs), piRNAs protect the genome from transposition, and therefore a tool to link piRNAs with complementary TE targets is needed. Tools like TEsma...

In recent years CRISPR-Cas9 knockouts (KO) have become increasingly utilized to study gene function. MicroRNAs (miRNAs) are short noncoding RNAs, 20–25 nucleotides long, which affect gene expression through posttranscriptional repression. As miRNAs are so small and due to the limitations of known PAM sequences, it is difficult to design CRISPR sgRN...

Whole-mount in situ hybridization (WISH) is a technique that enables temporal and spatial visualization of RNA molecules in an embryo or whole tissue by using a complementary labelled probe. MicroRNAs are short noncoding RNAs of 20-25 nt in length mainly involved in posttranscriptional regulation of gene expression. In this chapter, we describe how...

The tightly regulated feedback loops linking small RNAs (sRNAs) and transposable elements (TEs) offer the opportunity for an adaptive response to changing environments at the molecular level. Environmentally induced changes in TE and sRNA profiles may affect expression of coding genes and trigger an organismic and transgenerational response. Unders...

In recent years CRISPR-Cas9 knockouts (KO) have become increasingly ultilised to study gene function. MicroRNAs (miRNAs) are short non-coding RNAs, 20–22 nucleotides long, which affect gene expression through post-transcriptional repression. We previously identified miRNAs-196a and −219 as implicated in the development of Xenopus neural crest (NC)....

Somites arising from paraxial mesoderm are a hallmark of the segmented vertebrate body plan. They form sequentially during axis extension and generate musculoskeletal cell lineages. How paraxial mesoderm becomes regionalised along the axis and how this correlates with dynamic changes of chromatin accessibility and the transcriptome remains unknown....

The development of multicellular organisms is exquisitely regulated through differential gene activity, which governs cell differentiation programs. However, many details of spatiotemporal control of gene regulation are still poorly understood. We used the accessibility of chick embryos to examine genome-wide signatures characterizing the progressi...
