The chemistry and biological activity of the Hyacinthaceae [PDF]

open access: yes, 2013
Covering: 1914 to 2012The Hyacinthaceae (sensu APGII), with approximately 900 species in about 70 genera, can be divided into three main subfamilies, the Hyacinthoideae, the Urgineoideae and the Ornithogaloideae, with a small fourth subfamily the ...

Bufalin‐Induced Epithelial‐to‐Mesenchymal Transition in Kidney Epithelial Cells

open access: yesCell Biology International, Volume 49, Issue 12, Page 1764-1786, December 2025.
ABSTRACT The kidney plays a central role in fluid, electrolyte, and blood pressure regulation, processes tightly coupled to Na⁺/K⁺‐ATPase activity. Beyond its canonical transport function, Na⁺/K⁺‐ATPase also acts as a signaling receptor for cardiotonic steroids (CTSs) such as bufalin, which have been implicated in fibrosis and epithelial‐to‐mesenchymal

Polyphagous insect Olepa sps. feeding on cardenolide rich Calotropis gigantea (L.) leaves and detoxification mechanism involving GST

open access: yesHeliyon, 2022
Cardenolides, a group of cardiac glycosides are potent inhibitors of Na+/K+ ATPase pump in mammals, animals including insects. Some insects can circumvent the toxicity of cardenolides by mechanisms like target site resistance and metabolic resistance ...

Notes on Shifting Distribution Patterns and Survival of Immature \u3ci\u3eDanaus Plexippus\u3c/i\u3e (Lepidoptera: Danaidae) on the Food Plant \u3ci\u3eAsclepias Syriaca\u3c/i\u3e [PDF]

open access: yes, 2017
Abundance and distribution of immature stages of the monarch butterfly, Danaus plexippus, on the food plant Asclepias syriaca were examined at a site in southeastern Wisconsin over one growing season.

Host plants and experimental warming impact fitness and infection outcomes in a migratory butterfly

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1159-1171, December 2025.
Host plant species interacted with temperature treatment to shape monarch survival and infection probabilities. Temperature modified the expected role of tropical milkweed, which did not confer OE resistance to monarchs under elevated temperatures.

Mate Choice and Toxicity in Two Species of Leaf Beetles with Different Types of Chemical Defense [PDF]

open access: yes, 2018
Evidence for the use of defensive compounds for sexual purposes is scarce, even though sexual selection might have some importance for the evolution of defensive traits. This study investigates the effect of defense-related traits and body size on mating

Interspecific differences in the larval performance of Pieris butterflies (Lepidoptera: Pieridae) are associated with differences in the glucosinolate profiles of host plants

open access: yes, 2019
The tremendous diversity of plants and herbivores has arisen from a coevolutionary relationship characterized by plant defense and herbivore counter adaptation. Pierid butterfly species feed on Brassicales plants that produce glucosinolates as a chemical

Evolutionary Changes of GT1 Provide Insights Into the Adaptation of Butterflies to Plant Feeding

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
We investigated the evolution of glycosyltransferase 1 (GT1) genes in 69 butterfly species to explore their association with host plant adaptation. Our results reveal frequent tandem duplications and adaptive selection in GT1s, especially in UGT33 and UGT40 subfamilies, alongside expression patterns suggesting functional diversification.
