| 1 | A Comparative Study on the Role of Cytokinins in Caryopsis Development in the Maize miniature1 Seed Mutant and Its Wild Type显示文摘We report here on a comparative developmental profile of plant hormone cytokinins in relation to cell size,cell number and endoreduplication in developing maize caryopsis of a cell wall invertase-deficient miniature1(mn1) seed mutant and its wild type,Mn1,genotype.Both genotypes showed extremely high levels of total cytokinins during the very early stages of development,followed by a marked and genotype specific reduction.While the decrease of cytokinins in Mn1 was associated with their deactivation by 9-glucosylation,the absolute and the relative part of active cytokinin forms was higher in the mutant.During the exponential growth phase of endosperm between 6 d after pollination and 9 d after pollination,the mean cell doubling time,the absolute growth rate and the level of endoreduplication were similar in the two genotypes.However,the entire duration of growth was longer in Mn1 compared with mn1,resulting in a significantly higher cell number in the Mn1 endosperm.These data correlate with the previously reported peak levels of the Mn1-encoded cell wall invertase-2(INCW2) at 12 d after pollination in the Mn1 endosperm.A model showing possible crosstalk among cytokinins,cell cycle and cell wall invertase as causal to increased cell number and sink strength of the Mn1 developing endosperm is discussed. | Tomaz Rijavec Maja Kova Ale Kladnik Prem S.Chourey Marina Dermastia | 2009 | Journal of Integrative Plant Biology2009，51，9： | 7 |

| 3 | Regulated upon activation,normal T cell expressed and secreted(RANTES)levels in the peripheral blood of patients with Alzheimer’s disease显示文摘Alzheimer’s disease(AD)is the most common type of dementia,but it is very difficult to diagnose with certainty,so many AD studies have attempted to find early and relevant diagnostic markers.Regulated upon activation,normal T cell expressed and secreted(RANTES,also known as C-C chemokine ligand)is a chemokine involved in the migration of T cells and other lymphoid cells.Changes in RANTES levels and its expression in blood or in cerebrospinal fluid have been reported in some neurodegenerative diseases,such as Parkinson’s disease and multiple sclerosis,but also in metabolic diseases in which inflammation plays a role.The aim of this observational study was to assess RANTES levels in peripheral blood as clinical indicators of AD.Plasma levels of RANTES were investigated in 85 AD patients in a relatively early phase of AD(median 8.5 months after diagnosis;39 men and 46 women;average age 75.7 years),and in 78 control subjects(24 men and 54 women;average age 66 years).We found much higher plasma levels of RANTES in AD patients compared to controls.A negative correlation of RANTES levels with age,disease duration,Fazekas scale score,and the medial temporal lobe atrophy(MTA)score(Scheltens’s scale)was found in AD patients,i.e.,the higher levels corresponded to earlier stages of the disease.Plasma RANTES levels were not correlated with cognitive scores.In AD patients,RANTES levels were positively correlated with the levels of pro-inflammatory cytokines interleukin-6 and tumor necrosis factor-α,which is consistent with the wellknown fact that AD is associated with inflammatory processes.RANTES levels were also positively correlated with insulin levels in AD patients,with insulin resistance(HOMA-R)and pancreatic beta cell function(HOMA-F).This study evaluated several clinical and metabolic factors that may affect plasma levels of RANTES,but these factors could not explain the increases in RANTES levels observed in AD patients.Plasma levels of RANTES appear to be an interesting peripheral marker for early stages of AD.The study was approved by the Ethics Committee of Institute of Endocrinology,Prague,Czech Republic on July 22,2011. | Gabriela Vacínová Daniela Vejražkova Robert Rusina Iva Holmerová Hana Vaňková Eva Jarolímová Josef Včelák Běla Bendlová Markéta Vaňková | 2021 | Neural Regeneration Research2021，16，4： | 3 |
