Introduction: Obesity is characterized by excessive fat accumulation resulting from adipocyte hypertrophy and hyperplasia, with adipocyte differentiation being a central process driving these changes.
Methods: The anti-adipogenic effects of CRT0066101 (CRT), a pan-protein kinase D (PKD) inhibitor, were evaluated in 3T3-L1 adipocytes. Potential drug targets of CRT were predicted using network pharmacology analysis.
The tomato leaf miner, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is a significant invasive species globally, inflicting considerable damage on tomato industry. Tetraniliprole is a new type of diamide insecticides, which can effectively control lepidoptera insects. In this study, we investigated both the acute toxicity and sublethal effects of tetraniliprole on T.

Breeding whitefly-resistant tomato varieties is a promising and environmentally friendly method to control whitefly populations in the field. Accumulating evidence from tomato and other model systems demonstrates that flavonoids contribute to plant resistance to herbivorous insects.

Here, we investigate the involvement of mA methylation in imidacloprid resistance in the whitefly . Our results identify five core mA methyltransferases linked to imidacloprid resistance.

Plant-mediated interactions between TYLCV and vector whiteflies commonly occur when previous infestations induce both volatile and nonvolatile changes in the shared host. These induced changes of the shared host may differentially affect subsequent interacting species within the plant-insect-virus tripartite system.

Ineffective pest control has been reported in multiple regions, raising concerns about food safety risks due to improper insecticide use. To evaluate insecticide susceptibility and the role of detoxification enzyme involvement, resistance monitoring and enzyme activity assays were conducted.

The rapid and complex evolution of insecticide resistance, along with the molecular mechanisms of abamectin resistance in T. urticae, are not fully elucidated, representing a significant impediment to the effective management of pest resistance.
View Article and Find Full Text PDFPlants can deploy chemical defenses that poison herbivorous insects or deter their feeding; however, insects can counter by secreting effector proteins that modulate these defense responses. In principle, plants might therefore interfere with the expression of insect effector proteins, but knowledge about such a process remains limited. Here, we explored the mechanisms underlying how resistant tomato (Solanum lycopersicum) influences the effector proteins of whiteflies (Bemisia tabaci), thereby affecting the interaction of B.
View Article and Find Full Text PDFTomato yellow leaf curl virus (TYLCV), a devastating pathogen of tomato crops, is vectored by the whitefly , yet the mechanisms underlying TYLVC epidemics are poorly understood. We found that TYLCV triggers the up-regulation of two β-myrcene biosynthesis genes in tomato, leading to the attraction of nonviruliferous . We also identified BtMEDOR6 as a key whitefly olfactory receptor of β-myrcene involved in the distinct preference of MED for TYLCV-infected plants.

The recent discovery that various insects have acquired functional genes through horizontal gene transfer (HGT) has prompted numerous studies into this puzzling and fascinating phenomenon. So far, horizontally transferred genes are found to be functionally conserved and largely retained their ancestral functions. It evidently has not yet been considered that horizontally transferred genes may evolve and can contribute to divergence between species.

After invading large countries like Australia, China, and the USA, MEAM1 spread rapidly across each country. In contrast, our analysis of MEAM1 in India showed a very different pattern.
View Article and Find Full Text PDFBackground: The whitefly Bemisia tabaci is a notorious agricultural pest known for its ability to cause significant crop damage through direct feeding and virus transmission. Its remarkable adaptability and reproductive capacity are linked to its ability to acquire and integrate horizontally transferred genes (HTGs) into its genome. These HTGs increase the physiological and metabolic capacities of this pest, including cholesterol synthesis, which is critical for its survival and reproductive success.

The preference of each PBP is believed to be different for each pheromone component within a single species.

Epoxy resin (EP) based composite materials, due to their advantages such as light weight, ease of processing, and mechanical properties, have been widely applied across thermal packaging field. However, the overall thermal conductivity is constrained by the interfacial thermal resistance between the filler and the substrate. Existing studies suggest that self-assembled monolayers (SAM) can enhance the interfacial thermal conductance (ITC) by forming covalent bonds.

Microorganisms symbiotic with insects, whether permanently or temporarily, play a crucial role in the nutrition, development, reproduction, defence, and metamorphosis regulation. In some Lepidoptera, oviposition-deterrent pheromones (ODPs) on egg surface were used by pregnant females to modify the behaviour of conspecifics to avoid excessive competition for limited resources. In this study, we constructed four different groups, including, OH, OA, SH, and OA, which either feed on different hosts or grow in different environments.

Our previous study revealed that spinosad-resistant Frankliniella occidentalis (NIL-R) exhibited reduced fecundity and significant changes in JHBP/TO family gene expression. We hypothesized that these genes were involved in regulating the fitness costs associated with resistance.

Mounting evidence suggests that insect hormones associated with growth and development also participate in pathogen defense. We have discovered a previously undescribed midgut transcriptional control pathway that modulates the availability of 20-hydroxyecdysone (20E) in a worldwide insect pest (), allowing it to defeat the major virulence factor of an insect pathogen (Bt). A reduction of the transcriptional inhibitor (PxDfd) increases the expression of a midgut microRNA (miR-8545), which in turn represses the expression of a newly identified ecdysteroid-degrading glucose dehydrogenase (PxGLD).

However, little is known about the effects of non-vector herbivore infestation on virus transmission by vector insects on neighboring plants through inter-plant airborne chemicals. In this study, we investigated how volatiles emitted from tomato plants infested with the two-spotted spider mite (Tetranychus urticae) affect the infection of neighboring plants by tomato yellow leaf curl virus (TYLCV) transmitted by whitefly (Bemisia tabaci).

It has become a new challenge to treat multiple pulmonary nodules and obtain a favorable prognosis while minimizing the perioperative risk for patients. The purpose of this study was to summarize the preliminary experience with a hybrid surgery combining pulmonary resection and ablation for the treatment of sMPLC and to discuss the feasibility of this novel procedure with a literature review.

Background: Temperature is a primary factor that determines the eco-geographical distribution and population development of invasive insects. Temperature stress leads to various negative effects, including excess reactive oxygen species (ROS), and catalase (CAT) is a key enzyme against ROS in the antioxidant pathway. The whitefly Bemisia tabaci MED is a typical invasive pest that causes damage worldwide.
