Transcriptional activation of human leukosialin (CD43) gene by Sp1 through binding to a GGGTGG motif
Tssc3 is a maternally expressed/paternally silenced imprinted gene. Recent evidence suggests that the loss of TSSC3 results in placental overgrowth in mice. These findings showed that the TSSC3 gene functions as a negative regulator of placental growth. In this study, we describe the function of TSSC3 and its signaling pathway in mouse trophoblast stem (TS) cell differentiation. First of all, w...
UDP-glucose dehydrogenase (UGDH) catalyzes the conversion of UDP-glucose to UDP-glucuronic acid, which is required in liver for the excretion of toxic compounds, and for the biosynthesis of complex carbohydrates, such as hyaluronan, in many cell types. Analysis of a human EST database, as well as the results of a 5'-RACE experiment, have revealed the presence of two transcription start sites ap...
CACCC-boxes are recognised by transcription factors of the Sp/Krüppel-like Factor (Sp1/KLF) family. Here we describe one member of this family, KLF8/ZNF741/BKLF3 (KLF8). KLF8 contains a characteristic C-terminal DNA-binding domain comprised of three Krüppel-like zinc fingers, but also has limited homology to another family member, KLF3/Basic Krüppel-like Factor (KLF3/BKLF), in its N-terminus. M...
We study the computational complexity of two well-known graph transversal problems, namely Subset Feedback Vertex Set and Odd Cycle Transversal, by restricting input to H-free graphs, that is, graphs do not contain some fixed H as an induced subgraph. By combining known new results, we determine both problems on for every except when H=sP1+P4 s≥1. As part our approach, introduce Cover problem p...
PURPOSE Increasing evidence indicates that the transcription factor, Sp1, regulates the expression of multiple genes involved in tumor development and progression. We have recently reported that Sp1 overexpression is directly correlated with the angiogenic potential of and poor prognosis for human gastric cancer. However, the underlying mechanisms that result in Sp1 overexpression remain unclea...
رشته غنی از سیتوزین قادر است ساختار i-motif dna را تشکیل دهد. مطالعات نشان داده است که با پایدار کردن این ساختار می توان از تشکیل ساختار دو رشته ای و در نتیجه طویل شدن طول تلومرها جلوگیری کرد. داروی تاموکسیفن یک عامل هورمونی ضد استروژن برای درمان سرطان سینه می باشد که برای مدت زیادی به منظور درمان سرطان سینه به کار می رود. در این تحقیق در مرحله اول امکان اندازه گیری الکتروشیمیایی داروی تاموکسیف...
BACKGROUND Specificity protein (Sp) 1 mediates the transcription of a large number of constitutive genes encoding physiological mediators. NF-κB mediates the expression of hundreds of inducible genes encoding pathological mediators. Crosstalk between Sp1 and NF-κB pathways could be pathophysiologically significant, but has not been studied. This study examined the crosstalk between the two path...
