Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

Advanced Science, EarlyView.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

HYDROGEOLOGICAL AND HYDROCHEMICAL FEATURES OF KALNIK MASSIF

Rudarsko-geološko-naftni Zbornik, 2008
Kalničko gorje consists of Cretaceous – Holocene sediments, which can be in hydrogeological sense classified in three hydrogeological units: (1) northern area from central massive of Kalnik, consists of Cretaceous and low Miocene impermeable and low ...

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Temporal and Cell‐Specific Regulation of Synaptic Homeostasis by the Chromatin Remodeler Chd1

Advanced Science, EarlyView.
Chd1, the Drosophila homologue of mammalian CHD2 ‐ a gene linked to autism, epilepsy, and intellectual disability, is required for synaptic homeostatic plasticity. Chd1 in glia is necessary for the rapid induction of synaptic homeostasis, whereas Chd1 in motoneurons, muscle, and glia is critical for long‐term maintenance.

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

Advanced Science, EarlyView.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...

Examination of the Nasal Botfly (Cephenemyia stimulator, Clark, 1815) in the Roe Deer (Capreolus capreolus, Linnaeus, 1758), in Hungary

Scientific Papers Animal Science and Biotechnologies, 2023
We examined roe deer in the southern part of Hungary, in different habitats, in the last two hunting seasons. The subject of the examination was the nasal botfly (Cephenemyia stimulator) larvae in the roe deer.

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

Advanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support
