Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]
, 2010 Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Selective modulation of P-glycoprotein activity by steroidal saponines from Paris polyphylla [PDF]
, 2009 Bio-guided fractionation of the roots of Paris polyphylla (Trilliaceae), based on inhibition of P-glycoprotein-mediated daunorubicin efflux in K562/R7 cell line, led to isolation and identification of the three saponins 3-O-Rha(1 → 2)[Ara(1 → 4)]Glc ...

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect Science, EarlyView.RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Retinoids Regulate a Developmental Checkpoint for Tissue Regeneration in Drosophila [PDF]
, 1949 SummaryDamage to Drosophila imaginal discs elicits a robust regenerative response from the surviving tissue [1–4]. However, as in other organisms, developmental progression and differentiation can restrict the regenerative capacity of Drosophila tissues.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing
Evolution &Development, Volume 28, Issue 2, June 2026.Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...
