磷酸甘油酸激酶1(phosphoglycerate kinase-1,PGK1)是糖酵解途径中第一个催化ATP生成的关键酶,主要功能是催化1,3-二磷酸甘油酸(1,3-bisphosphoglycerate,1,3-BPG)转化为3-磷酸甘油酸(3-phosphoglycerate,3-PG),并且通过底物水平磷酸化产生ATP。PGK1不仅具有代谢酶活性,在糖酵解过程中发挥重要作用,还具有蛋白激酶活性,可参与多种生命活动的调控,如介导血管生成、细胞自噬、DNA复制和修复、三羧酸(tricarboxylic acid,TCA)循环、肿瘤细胞增殖和转移等。在医学生物领域,翻译后修饰对基因稳定遗传、蛋白质定位、细胞代谢调控、DNA转录和翻译等至关重要。近年来研究表明,与PGK1相关的各种翻译后修饰在肿瘤的发生发展中起着重要的生物学作用,这不仅推动了癌症发病机制的研究,更为肿瘤患者提供了新的治疗方案。本文综述了PGK1翻译后修饰在肿瘤发生发展中的生物学功能研究。

Role of Elevated Thrombospondin-1 in Kainic Acid-Induced Status Epilepticus

Neuroscience Bulletin 2020年第3期36卷 263-276页

Previous studies have suggested that thrombospondin-1(TSP-1) regulates the transforming growth factor beta 1(TGF-b1)/phosphorylated Smad2/3(p Smad2/3) pathway. Moreover, TSP-1 is closely associated with epilepsy. However, the role of the TSP-1-regulated TGFb1/p Smad2/3 pathway in seizures remains unclear. In this study, changes in this pathway were assessed following kainic acid(KA)-induced status epilepticus(SE) in *** results showed that increases in the TSP-1/TGF-b1/p Smad2/3 levels spatially and temporally matched the increases in glial fibrillary acidic protein(GFAP)/chondroitin sulfate(CS56) levels following KA *** of TSP-1 expression by small interfering RNA or inhibition of TGF-b1 activation with a Leu-Ser-Lys-Leu peptide significantly reduced the severity of KA-induced acute seizures. These anti-seizure effects were accompanied by decreased GFAP/CS56 expression and Smad2/3 phosphorylation. Moreover, inhibiting Smad2/3 phosphorylation with ponatinib or SIS3 also significantly reduced seizure severity, alongside reducing GFAP/CS56 immunoreactivity. These results suggest that the TSP-1-regulated TGF-b1/p Smad2/3 pathway plays a key role in KA-induced SE and astrogliosis, and that inhibiting this pathway may be a potential anti-seizure strategy.

In osteoporosis scenario, tissue response to implants is greatly impaired by the deteriorated boneregeneration microenvironment. In the present study, a Mg-containing akermanite (Ak) ceramic wasemployed for the treatment of osteoporotic bone defect, based on the hypothesis that both beneficialions (e.g. Mg^2+ ect.) released by the implants and the weak alkaline microenvironment pH (μe-pH) itcreated may play distinct roles in recovering the abnormal bone regeneration by stimulating osteoblasticanabolic effects. The performance of Ak, b-tricalcium phosphate (β-TCP) and Hardystone (Har) in healinga 3 mm bone defect on the ovariectomized (OVX) osteoporotic rat model was evaluated. Our resultsindicated that, there's more new bone formed in Ak group than in β-TCP or Har group at week 9. Theinitial me-pHs of Ak were significantly higher than that of the β-TCP and Blank group, and this weakalkaline condition was maintained till at least 9 weeks post-surgery. Increased osteoblastic activity whichwas indicated by higher osteoid secretion was observed in Ak group at week 4 to week 9. An intermediatelayer which was rich in phosphorus minerals and bound directly to the new forming bone wasdeveloped on the surface of Ak. In a summary, our study demonstrates that Ak exhibits a superior boneregenerative performance under osteoporosis condition, and might be a promising candidate for thetreatment of osteoporotic bone defect and fracture.
