TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect 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.

Host plant pubescence: Effect on silverleaf whitefly, Bemisia argentifolii, fourth instar and pharate adult dimensions and ecdysteroid titer fluctuations

open access: yesJournal of Insect Science, 2003
The ability to generate physiologically synchronous groups of insects is vital to the performance of investigations designed to test insect responses to intrinsic and extrinsic stimuli. During a given instar, the silverleaf whitefly, Bemisia argentifolii,

Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Semi-Synthetic Ecdysteroid 6-Oxime Derivatives of 20-Hydroxyecdysone Possess Anti-Cryptococcal Activity

open access: yesMicrobiology Research, 2022
Cryptococcosis, a life-threatening fungal infection, frequently occurs in patients suffering from AIDS. The treatment of the disease is hampered by the limited number of the effective drugs and the increasing resistance; therefore, to find new active ...

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Identification of 20-hydroxyecdysone late-response genes in the chitin biosynthesis pathway. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: 20-hydroxyecdysone (20E) and its receptor complex ecdysone receptor (EcR) and ultraspiracle (USP) play a crucial role in controlling development, metamorphosis, reproduction and diapause.

Pharmacological intervention: Challenges and promising outcomes for fat loss and preservation of lean body mass in the treatment of overweight and type 2 diabetes

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 2, Page 803-816, February 2026.
Abstract Treatment with GLP‐1 receptor agonists (GLP‐1 RAs) is effective in reducing body weight in individuals with overweight and type 2 diabetes (T2D). However, measurements indicate that a considerable portion of the weight loss derives from fat‐free mass (FFM), including skeletal muscle, which may compromise metabolic health and physical function.

Timing is everything: PTTH mediated DHR4 nucleocytoplasmic trafficking sets the tempo of Drosophila steroid production

open access: yesFrontiers in Endocrinology, 2011
During development multicellular organisms must become sexually mature to reproduce. But what underlying developmental clock times this transition? Recent data shows that in fly larvae, nuclear-cytoplasmic trafficking of DHR4, a nuclear receptor, in ...
