Sexual reproduction depends on the production of haploid gametes, and their fusion to form
diploid zygotes. Here, we discuss sperm production and function in a molecular and …

… Comparison of the sequence of this protein with the sequence of the N-terminal peptide (95.1;
see above) indicates that Leu-25 of the precursor protein represents the N terminus of the …

… Citation 54 Notch (N) signaling is a key factor for initial niche (TF and CC) formation during
development, and thus plays a—possibly indirect—role for GSC maintenance, as loss of N …

During male gametogenesis, a developmentally regulated and cell type-specific transcriptional
programme is activated in primary spermatocytes to prepare for differentiation of sperm. …

The conservation of signaling cascades between humans and Drosophila, over more than
500 million years of evolutionary time, means that the genetic tractability of the fly can be used …

Appropriate regulation of signal transduction pathways is essential for normal development
and is often disrupted in disease. Therefore, many regulatory mechanisms and feedback …

Background Dysphagia is prevalent with cerebrovascular accidents and contributes to the
burden of disease and mortality. Strengthening dysfunctional swallow muscles through …

… In pigs, some reports showed dependence of binding on the presence of N-linked
carbohydrates [9], but others could not find a requirement for any glycosylation at all [10]. In some …

Cytokine receptors often act via the Janus kinase and signal transducer and activator of
transcription (JAK/STAT) pathway to form a signalling cascade that is essential for processes …

The interaction of chicken spermatozoa with the inner perivitelline layer from different avian
species in vitro during a 5 min co-incubation was measured as the number of points of …
