Identification and differential expression of microRNAs during metamorphosis of the Japanese flounder (Paralichthys olivaceus). [PDF]

PLoS ONE, 2011
BACKGROUND: MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs of 20-25 nucleotides that play a key role in diverse biological processes. Japanese flounder undergo dramatic metamorphosis in their early development.

Effect of thyroid hormone concentration on the transcriptional response underlying induced metamorphosis in the Mexican axolotl (Ambystoma)

BMC Genomics, 2008
Background Thyroid hormones (TH) induce gene expression programs that orchestrate amphibian metamorphosis. In contrast to anurans, many salamanders do not undergo metamorphosis in nature. However, they can be induced to undergo metamorphosis via exposure

Enzymatic activity of bone markers on Lithobates catesbeianus (Shaw, 1802) growth during the ossification process

Brazilian Journal of Biology, 2021
In order to better understand the ossification processes in anurans our study was carried out on tadpoles and adults of Lithobates catesbeianus. In this sense, we characterized the kinetic properties of alkaline phosphatase with p-nitrophenylphosphatase (

Relationship between serum thyroid hormones and their associated metabolites, and gene expression bioindicators in the back skin of Rana [Lithobates] catesbeiana tadpoles and frogs during metamorphosis

Frontiers in Endocrinology, 2023
Anuran metamorphosis is characterized by profound morphological changes including remodeling of tissues and organs. This transition is initiated by thyroid hormones (THs).

Temporal and spatial transcriptomic dynamics across brain development in Xenopus laevis tadpoles

G3: Genes, Genomes, Genetics, 2021
Amphibian metamorphosis is a transitional period that involves significant changes in the cell-type populations and biological processes occurring in the brain.

Identification and differential regulation of microRNAs during thyroid hormone-dependent metamorphosis in Microhyla fissipes

BMC Genomics, 2018
Background Anuran metamorphosis, which is obligatorily initiated and sustained by thyroid hormone (TH), is a dramatic example of extensive morphological, biochemical and cellular changes occurring during post-embryonic development.

The chemical metamorphosis of taxane diterpenes by synthetic design

, 2023
The construction of molecular carbon frameworks stands as the fundamental objective of organic chemistry. The carbon skeleton of each organic molecule serves as the foundation for its three-dimensional structure, playing a pivotal role in determining its

Virus Membrane Fusion Proteins: Biological Machines that Undergo a Metamorphosis

Bioscience Reports, 2000
Fusion proteins from a group of widely disparate viruses, including the paramyxovirus F protein, the HIV and SIV gp160 proteins, the retroviral Env protein, the Ebola virus Gp, and the influenza virus haemagglutinin, share a number of common features. All contain multiple glycosylation sites, and must be trimeric and undergo proteolytic cleavage to be ...

Amyloid Formation by Globular Proteins: The Need to Narrow the Gap Between in Vitro and in Vivo Mechanisms

Frontiers in Molecular Biosciences, 2022
The globular to fibrillar transition of proteins represents a key pathogenic event in the development of amyloid diseases. Although systemic amyloidoses share the common characteristic of amyloid deposition in the extracellular matrix, they are ...
