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

open access: yesBMC 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.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

open access: yesAdvanced Science, EarlyView.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

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

open access: yesFrontiers 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

open access: yesScientific 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.

Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator

open access: yesAdvanced Intelligent Systems, EarlyView.
Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.

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

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

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

open access: yesBMC 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.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

The presence of predators constrains larval development process by influencing critical developmental windows in the endangered Chinhai spiny newt

open access: yesEcology and Evolution
Predators significantly impact the development process and subsequently influence the metamorphic decisions of amphibian larvae. Larvae often exhibit induced growth and metamorphic plasticity in response to the presence of predators.
