Disruption of nucleotide biosynthesis reprograms mitochondrial metabolism to inhibit adipogenesis
A key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis.

Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Photoreactivation of Lethal Damage Induced in Hamster X Xenopus Hybrid Cells and Their Parentals by UV Light [PDF]
A85 Xenopus cells that exhibited a high level of photoreactivation (PR) and V79B2 hamster cells that exhibited little PR were fused to produce the V79B2 x A85 cell line — a hybrid line which possessed a relatively stable karyotype, with most cells ...

New developments are presented in the framework of the model introduced by the authors in refs. [1,2] and in which nucleotides as well as codons are classified in crystal bases of the quantum group U_q(sl(2)+sl(2)) in the limit q -> 0.

His+ reversions Caused in Salmonella typhimurium by different types of ionizing radiation [PDF]
The yield of his+ reversions in the Ames Salmonella tester strain TA2638 has been determined for 60Co γ rays, 140 kV X rays, 5.4 keV characteristic X rays, 2.2 MeV protons, 3.1 MeV α particles, and 18 MeV/U Fe ions.

1-Methyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one
The title molecule, C6H6N4O, is essentially planar [dihedral angle between the rings = 0.46 (9)°]. The crystal structure consists of sheets of molecules lying parallel to (\overline{1}11) formed by a combination of N—H...O, C—H...O and C—H...H hydrogen ...

Brain pyrimidine nucleotide synthesis and Alzheimer disease
Many patients suffering late-onset Alzheimer disease show a deficit in respiratory complex IV activity. The de novo pyrimidine biosynthesis pathway connects with the mitochondrial respiratory chain upstream from respiratory complex IV.
