The pyrimidine ribonucleotides, those found in RNA, are uracil and cytosine, each containing the sugar ribose and a nitrogenous base. Pyrimidine nucleotides contain a single ring in the nitrogenous base. In contrast to the synthesis of purines, the pyrimidine ring is synthesized first and then jo...

Feature of de novo synthesis for pyrimidine nucleotide is ( ).A.providing nitrogen atom by glutamateB.synthesizing carbamoyl phosphate first C.synthesizing base on the basis
In de novo synthesis of pyrimidines, the ring is synthesized first and then it is attached to ribose to form a pyrimidine nucleotide (Figure 25.2). Pyrimidine rings are assembled from bicarbonate, aspartic acid, and ammonia. Although ammonia can be used directly, it is usually produced from th...
de novo synthesis Leflunomide inhibits pyrimidine de novo synthesis in mitogen-stimulated T-lymphocytes from healthy humans Cdc6 is an unstable protein whose de novo synthesis in G1 is important for the onset of S phase and for preventing a ‘reductional’... ...

De novo nucleotide biosynthesis is required to meet the demand for maintaining energy, nucleotide levels, and new nucleic acids in dividing cells (1, 2). Synthesis of pyrimidine nucleotides in cancer cells utilizes glucose and glutamine for the carbon of the uracil and cytosine rings, which then...
AMPK interacts with the pyrimidinosome and restricts the association between the components of the complex and de novo synthesis of pyrimidine. When AMPK expression is low, the compactness of the pyrimidine biosynthetic complex is enhanced and de novo synthesis of pyrimidine is promoted. Upon energy...
近年来,随着内镜技术的发展,已能发现越来越多的微小和早期结直肠病变.部分报道曾描述了一种微小而极具侵袭性的结直肠癌,因其缺乏起源于腺瘤的证据,被称为"de novo癌(de novo carcinoma)".这类肿瘤由于挑战了经典的腺瘤癌变途径而引起众多争议,但由于其所显示的独特生物学特性,也得到了各国学者的充分重视.本文将...
