Association of Single Nucleotide Polymorphisms in Cysteamine Dioxygenase Gene with Taurine Content in Oyster Crassostrea gigas.

The Pacific oyster Crassostrea gigas is rich in taurine, a conditionally essential amino acid functioning in anti-oxidation, anti-inflammation, anti-aging, osmoregulation, and neuromodulation. Breeding oyster varieties with enhanced taurine content is significant to meet people's demand for high-quality oysters. In the present study, polymorphisms in the oyster cysteamine dioxygenase (CgADO) gene that encodes the central enzyme of the cysteamine pathway for taurine synthesis were investigated, and their association with taurine content was assessed in the Changhai (CH) and Qinhuangdao (QHD) populations.

The haemocyte highly-expressed E-type prostanoid receptor regulates TNF expression during immune response of oyster Crassostrea gigas.

Prostaglandin E2 imparts diverse physiological effects on multiple cells through its actions on four distinct E-type prostanoid (EP) receptor subtypes (EP1-EP4), among which the EP4 is one of subtypes known to mediate the immune response in mammalian monocytes and macrophages. However, the precise characteristics and functions of EP4 in mollusks remain unclear. In the present study, an EP4 homologue (designated as CgEP4) was identified from oyster Crassostrea gigas.

CgmiR307 involved in the regulation of Nrf2-dependent oxidative response in the Pacific oyster Crassostrea gigas under high-temperature stress.

miRNA, a type of endogenous small non-coding RNA, is involved in the response to various environmental stresses through post-transcriptional regulation. In the present study, the role of CgmiR307 in the regulation of oxidative response under high-temperature stress by targeting CgNrf2 was investigated in the Pacific oyster Crassostrea gigas.

1700030J22RIK is essential for sperm flagellar function and male fertility in mice.

Spermiogenesis is an indispensable process occurring during the later stages of spermatogenesis. Despite multiple proteins being associated with spermiogenesis, the molecular mechanisms that control spermiogenesis remain poorly characterized. In this study, we show that 1700030J22RIK is exclusively expressed in the testis of mice and investigate its roles in spermiogenesis using genetic and proteomic approaches.

Zscan4 mediates ubiquitination and degradation of the corepressor complex to promote chromatin accessibility in 2C-like cells.

Zygotic genome activation occurs in two-cell (2C) embryos, and a 2C-like state is also activated in sporadic (~1%) naïve embryonic stem cells in mice. Elevated chromatin accessibility is critical for the 2C-like state to occur, yet the underlying molecular mechanisms remain elusive. Zscan4 exhibits burst expression in 2C embryos and 2C-like cells.

Antimicrobial activity of octyl gallate nanoemulsion combined with photodynamic technology and its effect on food preservation.

Photodynamic inactivation, as a safe and effective antimicrobial technology that does not damage the organoleptic properties of the food itself, decreases the use of preservatives and is gradually gaining attention in the food industry. This study selected octyl gallate (OG) as an antimicrobial photosensitizer with eucalyptus oil as the oil phase and prepared it as an octyl gallate nanoemulsion (OG-NE) to ensure the delivery of the photosensitizer. Escherichia coli and Staphylococcus aureus inactivation with the OG-NE combined with photodynamic technology, as well as the effect on the quality of food products, was investigated.

KDM4 Regulates the Glycolysis of Hemocytes in the Immune Priming of .

Immune priming confers a sustained, augmented response of innate immune cells to a secondary challenge, a process that is characteristically reliant on metabolic reprogramming. Recent evidence suggests that histone demethylases play essential roles in the immune priming, while its regulation role in the metabolic reprogramming remains largely unknown. In the present study, the concentration of glucose was significantly down-regulated in the hemocytes of crab after secondary stimulation with , while the expression levels of phosphofructokinase (PFK) pyruvate kinase (PK), hexokinase-2 (HK-2) and Glucose-6-phosphate dehydrogenase (G-6-PD), along with the concentrations of lactate and the ratio of NAD/NADH, were elevated.

Hepatocyte HIF-2α Aggravates NAFLD by Inducing Ferroptosis through Increasing Extracellular Iron.

Recent research has illuminated the pivotal role of the hypoxia-inducible factor-2α (HIF-2α) / peroxisome proliferator-activated receptor alpha (PPARα) pathway in non-alcoholic fatty liver disease (NAFLD) progression. Meanwhile, HIF-2α was reported that involved in iron regulation, and aberrant iron distribution derived liver lipogenesis. Therefore, we hypothesize that HIF-2a exacerbates fatty liver by affecting iron distribution.

Anti-inflammatory and heat shock protein-inhibiting nanoplatform for synergetic cancer chemo/photothermal therapy.

Photothermal therapy is a novel and promising method for cancer treatment due to its controllable property, noninvasive nature, and high selectivity. Nevertheless, tumor recurrence of inflammatory response and tumor tolerance of heat shock protein over-expression remain serious challenges in current photothermal therapy. Additionally, the high dosage requirement of nanomaterial for optimal imaging and therapeutic effect would result in various side effects, organ excretion burdens, and long-term accumulation in the body.

The ATAC complex represses the transcriptional program of the autophagy-lysosome pathway via its E3 ubiquitin ligase activity.

The Ada two A-containing (ATAC) complex, containing histone acetyltransferases general control non-derepressible 5 (GCN5) or p300/CBP-associated factor (PCAF), has gained recognition as a prominent transcriptional coactivator. Recent revelations unveiled E3 ligase activity present in both GCN5 and PCAF; however, how the dual enzymatic activities of the ATAC complex orchestrate distinct transcriptional programs and signaling networks remains largely elusive. Our study unveils the function of the ATAC complex as a negative regulator of the autophagy-lysosome pathway's transcriptional program by modulating the stability of transcription factors TFE3 and TFEB.

A Zinc Uptake Transporter ZIP1-II Is Involved in Zinc Accumulation in the Hepatopancreas of Pacific Oyster Crassostrea gigas.

The Pacific oyster Crassostrea gigas is known to have an exceptional ability to accumulate zinc, which endows it with robust resistance to pathogens and makes it an excellent source of dietary zinc. ZIP1 has been identified as an important zinc uptake protein in other species, but its role in oysters remains unclear. In the present study, a ZIP1 homologue (CgZIP1-II) of the Zrt/Irt-like protein (ZIP) family was identified in C.

Immune stimulation by inactivated Vibrio splendidus promotes the development and resistance of oyster Crassostrea gigas larvae.

The oyster Crassostrea gigas larvae in embryonic development stage have been suffering high mortality rate during hatching, which have seriously hindered the sustainable development of oyster seedling industry.
