Autophagy studies in Bombyx mori [PDF]

Invertebrate Survival Journal, 2015
Autophagy, which is well conserved from yeast to mammals, plays essential roles in development and diseases. Using the domesticated silkworm, Bombyx mori, as a model insect, several reports on autophagy have been made recently.

Identification and characterisation of the ecdysone biosynthetic genes neverland, disembodied and shade in the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae). [PDF]

PLoS ONE, 2018
The salmon louse is a marine ectoparasitic copepod on salmonid fishes. Its lifecycle consists of eight developmental stages, each separated by a molt. In crustaceans and insects, molting and reproduction is controlled by circulating steroid hormones such

Autophagy Plays a Suppressive Role in Bladder Tumor Formation in an Orthotopic Mouse Model and Bladder Cancer Patient Specimens

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Autophagy plays either a suppressing or promoting role during tumor development. Clarifying the role of autophagy in bladder tumorigenesis both in vitro and in vivo is crucial for developing novel therapeutic strategies through manipulating autophagy activity.

Enhancement of 20-hydroxyecdysone production in cell suspension cultures of Vitex glabrata R.Br. by precursors feeding

, 2010
The effect of ecdysteroid precursors feeding on cell growth and 20-hydroxyecdysone production of Vitex glabrata suspension cultures were studied. On the addition of cholesterol, there was no apparentincrease of 20-hydroxyecdysone while growth was ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

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.
