Article Abstract

Penaeus vannamei is one of the most popular aquaculture species in the world. This species is featured with its fast-growing and delicious taste, which drives people develop various strains. During this process identification of trait-associated markers could effectively increase breeding efficiency. Driven by this, we tried to screen fast-growing key regulators via a FACS-based high throughput method, in which 2-NBDG was applied as a fluorescent indicator for direct glucose uptake measurement. Totally six candidate genes were screened out followed by in vitro validation in 293T cells. After that, the correlation between these genes and shrimp growing was further verified in a hybrid lineage. The expression level of two genes including ATP synthase subunit e and inhibitor of apoptosis protein showed some correlation with shrimp growth speed. Furthermore, we tested these two candidate markers in various lineages and confirmed that ATP synthase subunit e could be a shrimp growth-associated breeding marker.

Background: After spinal cord injury (SCI), pro-inflammatory microglia accumulate and impede axonal regeneration. We explored whether secreted protein acidic and rich in cysteine (Sparc) restrains microglial inflammation and fosters neurite outgrowth.

Methods: Mouse microglial BV2 cells were polarized to a pro-inflammatory phenotype with lipopolysaccharides (LPSs).

The insect midgut peritrophic membrane (PM) plays important roles in insect-microbe interactions. Bacillus thuringiensis (Bt) and its proteinaceous toxins are widely used for insect control. To understand the role of PM in insects against Bt toxins, this study selected Grapholita molesta Busck (Lepidoptera: Tortricidae), a worldwide pest infesting fruit trees, as the research subject.

Mitochondrial Complex V Deficiency Caused by a Homozygous Splice Variant in ATP5PO.

Most complex V subunits are nuclear encoded and so far, were not found in association with recognized Mendelian disorders. ATP5PO is a candidate gene for complex V mitochondrial disease. It encodes the oligomycin sensitivity-conferring protein (OSCP), an essential component of the "stalk" region that links the F1 and F0 domains of the ATP synthase complex.

The brain is a metabolically demanding organ as it orchestrates and stabilizes neuronal network activity through plasticity. This mechanism imposes enormous and prolonged energetic demands at synapses, yet it is unclear how these needs are met in a sustained manner. Mitochondria serve as a local energy supply for dendritic spines, providing instant and sustained energy during synaptic plasticity.

The interest in dry needling as a treatment option for myofascial pain has flourished for the last decades and will probably continue to do so, since multiple clinical effects can be attributed to this technique. However, evidence about the underlying physiological mechanisms of its effects is still underrepresented in scientific research and caution must be taken in generalizing results from acupuncture or animal research. This review offers an overview of the possible mechanisms involved in the pathophysiology of myofascial trigger points, i.
