主要方法:

潘尼乌斯·瓦纳米 (Penaeus vannamei) 接受了饮食中的富可伊丹补充剂,通过RNA干扰对GAT1基因进行了敲除,以及低盐度压力.
测量了GABA度,神经内分泌因子释放 (CRH,ACTH) 和血细胞和肠道中的免疫参数.
进行了基因表达分析和组织病理学检查.

主要成果:

GAT1基因倒置显著降低了GABA度.
神经内分泌因子 (CRH,ACTH) 升高,通过大脑结节-眼轴影响血细胞和肠道免疫力.
GABA直接影响了血细胞活动 (减少THC,细胞化,凝结,proPO,抗菌/细菌解毒活性;增加PO活性) 和肠道免疫力,加剧了损伤和氧化应激.

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Stringent Response in E. coli

Stringent Response in E. coli

Bacterial growth is closely tied to nutrient availability, with cells proliferating exponentially under favorable conditions and entering a stationary phase when resources become scarce. This transition is mediated by a regulatory mechanism known as the stringent response, which allows bacteria to adapt to nutrient deprivation by modulating gene expression and metabolic activity.During nutrient scarcity, intracellular amino acid levels decline. It results in the accumulation of uncharged tRNAs...
