Comparisons of genetic constraints across life stages and across temperatures from Genetic independence between traits separated by metamorphosis is widespread but varies with biological function

, 2023
Why is metamorphosis so pervasive? Does it facilitate the independent (micro)evolution of quantitative traits in distinct life-stages, like it enables some limbs and organs to develop at specific life-stages? We tested this hypothesis by measuring the expression of 6400 genes in 41 Drosophila melanogaster inbred lines at larval and adult stages.

Comparative transcriptomic analysis reveals gene regulation mediated by caspase activity in a chordate organism

BMC Molecular and Cell Biology, 2021
Background Apoptosis is a caspase regulated cell death present in all metazoans defined by a conserved set of morphological features. A well-described function of apoptosis is the removal of excessive cells during development and homeostasis.

Genome-Wide Analysis of MicroRNAs in Relation to Pupariation in Oriental Fruit Fly

Frontiers in Physiology, 2019
Insect metamorphosis is a complex process involving drastic morphological and physiological changes. microRNAs (miRNAs) are a class of endogenous small non-coding RNAs that play key roles in regulating various biological processes, including ...

miRNAs of Aedes aegypti (Linnaeus 1762) conserved in six orders of the class Insecta

Scientific Reports, 2021
Aedes aegypti L. is the most important vector of arboviruses such as dengue, Zika, chikungunya, Mayaro, and yellow fever, which impact millions of people’s health per year.

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Comparative transcriptomic analysis revealed dynamic changes of distinct classes of genes during development of the Manila clam (Ruditapes philippinarum)

BMC Genomics, 2022
Background The Manila clam Ruditapesphilippinarum is one of the most economically important marine shellfish. However, the molecular mechanisms of early development in Manila clams are largely unknown.

What is metamorphosis? [PDF]

, 2019
Metamorphosis (Gr. meta- “change” + morphe “form”) as a biological process is generally attributed to a subset of animals: most famously insects and amphibians, but some fish and many marine invertebrates as well.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

Advanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Teleost fish metamorphosis under the influence of estrogenic hormones: targeting the thyroid axis – a literature review

Environment International
Estrogens, whether naturally excreted by humans and livestock or introduced through pharmaceuticals, are endocrine-disrupting chemicals (EDCs) with strong estrogenic activity.
