Upon stimulation by Wnt ligands, the canonical Wnt/β-catenin signalling pathway results in the stabilization of β-catenin and its translocation into the nucleus to form transcriptionally active complexes with sequence-specific DNA-binding T-cell factor/lymphoid enhancer factor (TCF/LEF) family proteins. In the absence of nuclear β-catenin, TCF prot...
Tryptophan (TRP) is a precursor of serotonin (5-HT), which is known to affect food intake and aggression in vertebrates, including fishes. The effects of TRP-supplemented diets (0.25%, 0.5% and 1% of dry diet) on growth and cannibalism were evaluated in 38-day-old juvenile groupers (200-l tank, 750 fish per tank, 0.13 g in body weight and 2.16 cm i...
In vertebrates, the animal-vegetal axis is determined during oogenesis and at ovulation, the egg is radially symmetric. In anamniotes, following fertilization, a microtubule-dependent movement leads to the displacement of maternal dorsal determinants from the vegetal pole to the future dorsal side of the embryo, providing the initial breaking of ra...
The purpose of the present study was to compare the ability of larvae of different species, goldfish (Carassius auratus), zebrafish (Danio rerio), and ayu (Plecoglossus altivelis), to regulate their calcium balance. Whole-body Ca(2+) content and Ca(2+) influx in the larvae of the three species, which were incubated in low- (0.02 mM), mid- (0.2 mM),...
Angiomotin (Amot), the founding member of the Motin family, is involved in angiogenesis by regulating endothelial cell motility, and is required for visceral endoderm movement in mice. However, little is known about biological functions of the other two members of the Motin family, Angiomotin-like1 (Amotl1) and Angiomotin-like2 (Amotl2). Here, we h...
Human adipose-derived stem cells (ASCs) have shown immense potential for regenerative medicine. Our previous work demonstrated that chitosan nano-deposited surfaces induce spheroid formation and differentiation of ASCs for treating sciatic nerve injuries. However, the underlying cell fate and differentiation mechanisms of ASC-derived spheroids rema...
Bisphenol A (BPA) and diethyl phthalate (DEP) are estrogenic endocrine disrupting chemicals (EEDCs). The present study reconfirmed that the angle of the ceratohyal cartilage (CH) in embryos were larger from maternal BPA and E2, but smaller from DEP compared to the control. However, it is still unknown whether both the BPA and DEP chemicals disrupte...
Introduction
Compressive neuropathy, a common chronic traumatic injury of peripheral nerves, leads to variable impairment in sensory and motor function. Clinical symptoms persist in a significant portion of patients despite decompression, with muscle atrophy and persistent neuropathic pain affecting 10%–25% of cases. Excessive inflammation and immu...
How left-right (LR) asymmetry emerges in a patterning field along the anterior-posterior axis remains an unresolved problem in developmental biology. Left-biased Nodal emanating from the LR organizer propagates from posterior to anterior (PA) and establishes the LR pattern of the whole embryo. However, little is known about the regulatory mechanism...
Photodynamic inactivation (PDI) is a process that uses photosensitizing substances to produce reactive oxygen species. This is achieved by exposing photosensitizers to specific wavelengths of light and causing oxidative damage in cells. This sterilization technique is commonly utilized and has been extensively investigated owing to its environmenta...
The failure of peripheral nerve regeneration is often associated with the inability to generate a permissive molecular and cellular microenvironment for nerve repair. Autologous therapies, such as platelet-rich plasma (PRP) or its derivative platelet-rich growth factors (PRGF), may improve peripheral nerve regeneration via unknown mechanistic roles...
Urological chronic pelvic pain syndrome (UCPPS) manifests as pelvic pain with frequent urination and has a 10% prevalence rate without effective therapy. Nanoceria (cerium oxide nanoparticles [CNPs]) were synthesized in this study to achieve potential long‐term pain relief, using a commonly used UCPPS mouse model with cyclophosphamide‐induced cysti...
Interleukin-6 (IL-6) is a multifunctional cytokine involved in innate and acquired immunity. In mammals, IL-6 can induce the secretion of acute-phase proteins (APPs) and antimicrobial peptides, activate macrophages and neutrophils, and regulate the expression of inflammatory cytokines in innate immunity, resulting in enhanced resistance to invading...
The genetic regulation of vascular development is not elucidated completely. We previously characterized the transcription factors Islet2 (Isl2) and Nr2f1b as being critical for vascular growth. In this study, we further performed combinatorial microarrays to identify genes that are potentially regulated by these factors. We verified the changed ex...
Background
Epigenetic regulation by histone deacetylases (HDACs) in Schwann cells (SCs) after injury facilitates them to undergo de- and redifferentiation processes necessary to support various stages of nerve repair. Although de-differentiation activates the synthesis and secretion of inflammatory cytokines by SCs to initiate an immune response du...
Transcription activator-like effector nuclease (TALEN) technology has been widely used to edit nuclear genomes in plants but rarely for editing organellar genomes. In addition, ciprofloxacin, commonly used to cause the double-strand break of organellar DNA for studying the repair mechanism in plants, confers no organellar selectivity and site-speci...
Peripheral compressive neuropathy causes significant neuropathic pain, muscle weakness and prolong neuroinflammation. Surgical decompression remains the gold standard of treatment but the outcome is suboptimal with a high recurrence rate. From mechanical compression to chemical propagation of the local inflammatory signals, little is known about th...
Septins play important roles in regulating development and differentiation. Septin 7 (SEPT7) is a crucial component in orchestrating the septin core complex into highly ordered filamentous structures. Here, we showed that genetic depletion of SEPT7 or treatment with forchlorfenuron (FCF; a compound known to affect septin filament assembly) led to r...
As the worldwide application of nanomaterials in commercial products increases every year, various nanoparticles from industry might present possible risks to aquatic systems and human health. Presently, there are many unknowns about the toxic effects of nanomaterials, especially because the unique physicochemical properties of nanomaterials affect...
CaMKII is a Ca²⁺/CaM-dependent protein kinase encoded by a family of conserved genes found throughout all metazoan species and expressed from fertilization into adulthood. One of these genes, camk2g1, is particularly important during early development as determined by pharmacologic, dominant negative and antisense morpholino approaches in zebrafish...
VEGF stimulates the formation of new blood vessels by inducing endothelial cell (EC) proliferation and migration. Brefeldin A (BFA)‐inhibited guanine nucleotide–exchange protein (BIG)1 and 2 accelerate the replacement of bound GDP with GTP to activate ADP‐ribosylation factor (Arf)1, which regulates vesicular transport between the Golgi and plasma m...
The body temperatures of teleost species fluctuate following changes in the aquatic environment. As such, decreased water temperature lowers the rates of biochemical reactions and affects many physiological processes, including active transport-dependent ion absorption. Previous studies have focused on the impacts of low temperature on the plasma i...
The development and differentiation of steroidogenic organs are controlled by Ad4BP/SF-1 (adrenal 4 binding protein/steroidogenic factor 1). Besides, lysosomal activity is required for steroidogenesis and also enables adrenocortical cell to survive during stress. However, the role of lysosomal activity on steroidogenic cell growth is as yet unknown...
We report on the preparation of a biopolymer thin film by hydroxypropyl methylcellulose (HPMC), which can be used as a dry green lubricant in sustainable manufacturing. The thin films were characterized through scanning electron microscopy, energy-dispersive spectroscopy, and Raman spectroscopy; the films showed desirable levels of thickness, contr...
The antitumor drug etoposide (ETO) is widely used in treating several cancers, including adrenocortical tumor (ACT). However, when used at sublethal doses, tumor cells still survive and are more susceptible to the recurring tumor due to centrosome amplification. Here, we checked the effect of sublethal dose of ETO in ACT cells. Sublethal dose of ET...
p150(glued) is the largest subunit of dynactin protein complex, through which cargo vesicles link to the microtubule minus-end directed motor protein dynein. In addition, p150(glued) is also located in the mother centriole where it organized the subdistal appendage. The components of appendage are dynamically regulated throughout the cell cycle sta...
This study examined how developing fish larvae regulate their Ca2+ balance for acclimation to low ambient Ca2+. Calcium balance in newly hatched larvae was examined individually. Developing larvae not only increased Ca2+ influx but also decreased Ca2+ efflux when they were acclimated to low-Ca2+ environments. After acclimation for 8 days, the influ...
