Nucleotides: Structure and Properties [PDF]
, 2005 Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Long-term (trophic) purinergic signalling: purinoceptors control cell proliferation, differentiation and death [PDF]
, 2010 The purinergic signalling system, which uses purines and pyrimidines as chemical transmitters, and purinoceptors as effectors, is deeply rooted in evolution and development and is a pivotal factor in cell communication.

Basis for the control of purine biosynthesis by purine ribonucleotides. [PDF]
Journal of Clinical Investigation, 1981 An animal model was used to determine the basis for the increase in purine biosynthesis that results from hepatic depletion of purine nucleotides, such as seen in patients with type I glycogen storage disease or following fructose administration. Mice were injected intravenously with glucose or fructose, 2.5 mg/g of body weight, and the animals were ...

Serine, but not glycine, supports one-carbon metabolism and proliferation of cancer cells [PDF]
, 2014 Previous work has shown that some cancer cells are highly dependent on serine/glycine uptake for proliferation. Although serine and glycine can be interconverted and either might be used for nucleotide synthesis and one-carbon metabolism, we show that ...

Molecular Oncology, EarlyView.Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance
Molecular Oncology, EarlyView.In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...
