Meanwhile,HDAC1 acetylation level is significantly increased.The overexpression of HDAC1 can promote erythroid cell proliferation and inhibits induced differentiation,the knockdown of HDAC1 or 2 inhibits erythroid cell proliferation and promotes induced differentiation.We also found that HDAC1 affects GATA1 mediated transcription activity.Thus our data revealed that HDAC1 may negatively regulate GATA1 mediated transcription and suggest that the dynamic regulation of GATA1 associated NuRD/MeCP1/HDAC1/HDAC2 complex may determine the onset of erythroid differentiation programs.Moreover,this study will eventually help to design new therapeutic approaches in treatment of leukemia.

研究发现在被诱导分化的小鼠红细胞白血病细胞中与GATA1相结合的HDAC1被乙酰化并失去活性，在血细胞中过表达HDAC1能够促进血细胞的增殖并抑制分化，反之在血细胞中敲除HDAC1或HDAC2能抑制血红细胞的增殖并促进分化，而且HDAC1能够负调控GATA1的转录活性，GATA1与NuRD/MeCP1复合体之间的动态调控，决定血红细胞分化的发生和发展，并为探索白血病的致病机理奠定了理论基础。

Plant often subject to many biotic and abiotic factors in plant growth and development phases, and it must adapt to the environment through regulation of genes. Transcription factors play important roles in plant development and its response to the environment, so we need to research the function of transcription factors deeply.

植物在生长发育过程中经常遭受到许多生物和非生物因素的胁迫，需要通过对基因的调控来适应，而转录因子在植物的生长发育和防卫反应的表达调控中有着非常重要的作用，因此需要对转录因子的功能进行深入的研究。

The levels of E2F1 proteins could return to normal at 2h and 16h in high MOI infected cells treated with large dosage of allitridin.⑤The effects of allitridin on regulating the transcription and expression of dhfr gene in HCMV infected cells: The higher transcription of dhfr gene of high MOI infected cells within 4-16h was partially or wholely antagonised by allitridin. The up-regulated dhfr mRNA levels of low MOI infected cells nearly returned to normal after allitridin treatment.

大蒜新素处理HCMV感染细胞对E2F蛋白表达的影响：大蒜新素处理低MOI和高MOI感染细胞可使病毒诱导上调的E2F蛋白表达水平下调，大剂量药物处理高MOI感染细胞2h和16h时E2F蛋白回复至正常细胞水平，其作用特点为：药物对高MOI感染细胞的拮抗作用优于对低MOI感染细胞的处理；大剂量药物作用优于中剂量药物；对病毒在感染早期（16h内）诱导效应的拮抗作用强于对病毒感染中期（24h）诱导效应的拮抗。

The dose-dependent experiment revealed that Id1 antagonised E47 and Ets1 mediated transcriptional activation in a dose-dependent manner. With pGL3-870 as a template, site-directed mutagenesis of E-box and / or ETS-binding site was introduced into p16 promoter. E47 could not activate the transcription of p16 promoter with E-boxes mutated, and Ets1 could not activate the transcription of p16 promoter with EBS mutated. The synergy effect between E47 and Ets1 would occur only if the E-boxes and EBS were present. These facts demonstrated that E47 and Ets1 proteins were not recruited to the promoter by binding to other cis-elements or through interaction with other protein factors, however, they bound to DNA directly through respective consensus sequences in p16 promoter.

以pGL3-870为模板，构建了E-box或/和EBS点突变的p16启动子报告基因载体，将野生型和突变型的报告载体分别与pI-E47、pI-Etsl以及pI-E47+pI-Ets1共转染，发现E47和Ets1所诱导的转录激活作用依赖于启动子DNA上存在的各自的特异结合序列，二者的协同作用也只有当两个结合位点都存在时才会发生，说明E47和Ets1不是与其它作用元件或其它蛋白质因子相作用而被招募到该启动子的，它们是通过启动子上各自的特异结合位点与DNA直接结合的。

Chinese character transcription of all speakers' spontaneous monologues, including paralinguistic and non-linguistic information. Please refer to Specification of Transcription

研究结果对于人们进一步了解RNA聚合酶Ⅲ的转录机制、加工和运输过程及RNA聚合酶之间的结构与功能关系等均具有重要的意义。

Western blot analysis with the antiserum ATP95 revealed a significant increase of protein amounts of the V-H〓-ATPase subunits B and c of S. slasa under 100 and 400 mmol/L NaCl treatment, which gave another evidence for a salt-induced coordinate up-regulation of V-H〓-ATPase subunits at transcription and translation levels. The coordinated salt-induced increase of subunit B, H and c of V-H〓-ATPase from S. salsa at transcription and translation levels indicated an increase of V-H〓-ATPase holoenzyme amounts, which might be the reason for the increase of V-H〓-ATPase activity of S. salsa under salt stress.
