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

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 ...

METAMORPHOSIS AND IDENTITY CONSTRUCTION IN SALMAN RUSHDIE’S THE SATANIC VERSE [PDF]

University of Bucharest Review. Literary and Cultural Studies Series, 2022
Metamorphic spaces (temporal, geographical and mental) produce metamorphic bodies and identities. Metamorphosis arises as a dynamic principle of survival in borderline zones.

Divergent nucleic acid allocation in juvenile insects of different metamorphosis modes

Scientific Reports, 2021
Nucleic acids help clarify variation in species richness of insects having different metamorphosis modes, a biological conundrum. Here we analyse nucleic acid contents of 639 specimens of aquatic insects collected from four high mountain streams of ...

Tadpole growth rates and gut bacterial community: Dominance of developmental stages over temperature variations.

PLoS ONE, 2023
Tadpoles present an intriguing model system for studying the regulation and selection of gut microbiota. They offer a unique perspective to enhance our understanding of host-microbiota interactions, given their capacity to alter the dynamics of the gut ...

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

Angewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.

Differential effects of 3,5-T2 and T3 on the gill regeneration and metamorphosis of the Ambystoma mexicanum (axolotl)

Frontiers in Endocrinology, 2023
Thyroid hormones (THs) regulate tissue remodeling processes during early- and post-embryonic stages in vertebrates. The Mexican axolotl (Ambystoma mexicanum) is a neotenic species that has lost the ability to undergo metamorphosis; however, it can be ...
