Mitonuclear Communication in Stem Cell Function

open access: yesCell Proliferation, EarlyView.
In this review, we highlight the critical functions of mitonuclear communication and its impact on mitochondrial proteostasis. Additionally, we examine how mitonuclear signalling influences stem cell function, offering new insights into cellular homeostasis, stem cell therapies, and the potential for lifespan extension.

Steroid Receptors and Vertebrate Evolution [PDF]

open access: yesarXiv, 2019
Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

Structure of human steroid 21-hydroxylase genes. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1986
We have determined the structure of cDNA and two genomic genes encoding steroid 21-hydroxylase [21-OHase; steroid 21-monooxygenase; steroid, hydrogen-donor:oxygen oxidoreductase (21-hydroxylating); EC 1.14.99.10]. If this cytochrome P-450 enzyme is defective, cortisol cannot be synthesized, resulting in congenital adrenal hyperplasia. The cDNA encoding

Derivatives of MOPS: promising scaffolds for SARS coronaviruses Macro domain‐targeted inhibition

open access: yesThe FEBS Journal, EarlyView.
The SARS‐CoV/CoV‐2 genome encodes non‐structural protein 3, which contains a ‘Macro domain’. This protein domain exhibits antagonistic activity against interferon signaling, which disrupts the host innate immune response and can thus mediate viral escape, highlighting its therapeutic potential.

Symmetric Tensor Decomposition by an Iterative Eigendecomposition Algorithm [PDF]

open access: yesarXiv, 2014
We present an iterative algorithm, called the symmetric tensor eigen-rank-one iterative decomposition (STEROID), for decomposing a symmetric tensor into a real linear combination of symmetric rank-1 unit-norm outer factors using only eigendecompositions and least-squares fitting. Originally designed for a symmetric tensor with an order being a power of

The gut‐microbiota‐brain axis: Focus on gut steroids

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract There are over 1000 varieties of steroids that have been reported in nature, including the endogenous sex steroid hormones (i.e., progesterone, testosterone, and 17β‐estradiol) and corticosteroids which are mainly synthesized by gonads and adrenals, respectively.

Neuroactive steroid exposure impacts neurodevelopment: Comparison of human and rodent placental contribution

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract The placenta is a fetal endocrine organ that secretes many neuroactive factors, including steroids, that play critical roles in brain development. The study of the placenta‐brain axis and the links between placental function and brain development represents an emerging research area dubbed “neuroplacentology.” The placenta drives many ...

Vibrational properties of inclusion complexes: the case of indomethacin-cyclodextrin [PDF]

open access: yes, 2006
Vibrational properties of inclusion complexes with cyclodextrins are studied by means of Raman spectroscopy and numerical simulation. In particular, Raman spectra of the non-steroidal, anti-inflammatory drug indomethacin undergo notable changes in the energy range between 1600 and 1700 cm$^{-1}$ when inclusion complexes with cyclodextrins are formed ...

Aldosterone and Dexamethasone Activate African Lungfish Mineralocorticoid Receptor: Increased Activation After Removal of the Amino-Terminal Domain [PDF]

open access: yesarXiv, 2021
Aldosterone, the main physiological mineralocorticoid in humans and other terrestrial vertebrates, first appears in lungfish, which are lobe-finned fish that are forerunners of terrestrial vertebrates. Aldosterone activation of the MR regulates internal homeostasis of water, sodium and potassium, which was critical in the conquest of land by ...

Remodeling of the terpenoid metabolism during prolonged phosphate depletion in the marine diatom Phaeodactylum tricornutum

open access: yesJournal of Phycology, EarlyView.
Abstract Terpenoids are a diverse class of naturally occurring organic compounds, which derive from five‐carbon isoprene units and play crucial roles in physiology, ecological interactions such as defense mechanisms, or adaptation to environmental stresses.
