Highlights Increased glutamate is associated with the development of diabetes. Glutamate increases plasminogen (PLG) levels through glutamate metabotropic receptor 5 activation with various insulin resistance‐related stresses. Glutamate inhibits the conversion of PLG to plasmin by increasing plasminogen activator inhibitor‐1.

Highlights The CD4 T cells of type 1 diabetes (T1D) patients particularly having HLA‐DRB1*03‐DQA1*05‐DQB1*02 haplotype are reactive against a particular region of the glutamic acid decarboxylase (GAD65) protein. GAD65 peptides encompassing 288–308 amino acid positions (peptide pool 2) may be favored by the HLA‐DR3 molecule for presentation to CD4 T ...

ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...

ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

塔里木沙漠公路防护林土壤微生物生物量与土壤环境因子的关系 [PDF]
为探讨极端干旱区风沙土土壤微生物与土壤环境因子的作用规律,采用相关分析法研究了塔里木沙漠公路防护林地土壤微生物生物量与理化因子和酶活性的关系.结果表明:土壤容重和粒径减小(R0.85)时,防护林地中土壤微生物数量和生物量有增大趋势,由容重与微生物量的相关性主导;土壤养分含量与土壤微生物数量和生物量呈正相关,主要由速效养分和放线菌、微生物生物量C、P的相关性所致;土壤酶活性与土壤微生物数量和生物量的相关性差异较大,R在0.51~0.91,主要取决于蔗糖酶、磷酸酶与放线菌、微生物量C的相关 ...

Study of the expression of alkaline phosphatase in Amphidinium carterae Hulbert and Cofactor requirement [PDF]
磷(P)是浮游植物生长发育必须的营养元素之一,当环境中的无机磷浓度不足时(磷限制),浮游植物就会通过表达碱性磷酸酶(AP),以分解环境中的有机磷来维持自己的生长所需。甲藻是海洋生态系统中重要的浮游植物类群,同时也是形成有害藻藻华的主要类群,开展对AP的研究可以帮助我们更清楚地了解在自然海区和形成水华过程中,甲藻利用磷的分子机制及对其自身生长的影响。碱性磷酸酶基因表达的分子机制研究在甲藻中的研究目前刚刚起步,目前该基因的报道仅限于甲藻中个别代表种,如强壮前沟藻 ...
