In vitro synthesis of particulate glycogen from uridine diphosphate glucose [PDF]

Archives of Biochemistry and Biophysics, 1969
Abstract High molecular weight glycogen has been prepared in vitro with liver glycogen synthetase (uridine diphosphate glucose: α-1,4-glucan α-4-glucosyltransferase, EC 2.4.1.11) and branching enzyme (α-1,4-glucan: α-1,4-glucan 6-glycosyltransferase, EC 2.4.1.18) and uridine diphosphate glucose as glucose donor.

Y12C mutation disrupts IMPDH cytoophidia and alters cancer metabolism

The FEBS Journal, EarlyView.
IMPDH, the rate‐limiting enzyme for de novo GTP synthesis, can form polymers and cytoophidia to enhance activity by reducing GTP inhibition. In this study, a Y12C mutation in IMPDH2 was introduced via ABEmax base‐editing in human cancer cell lines to disrupt IMPDH polymerisation.

ATR inhibition facilitates targeting of leukemia dependence on convergent nucleotide biosynthetic pathways. [PDF]

, 2017
Leukemia cells rely on two nucleotide biosynthetic pathways, de novo and salvage, to produce dNTPs for DNA replication. Here, using metabolomic, proteomic, and phosphoproteomic approaches, we show that inhibition of the replication stress sensing kinase ...

P2Y14 receptor activation of platelets induces Ca2+ mobilization and Rho‐GTPase‐dependent motility that requires an interaction with P2Y1 receptors

British Journal of Pharmacology, Volume 182, Issue 13, Page 2950-2967, July 2025.
Background and Purpose Platelet function during inflammation is dependent on activation by endogenous nucleotides acting on purinergic receptors. The P2Y14 receptor has been reported to be expressed on platelets and is involved in leukocyte recruitment during inflammation.

In Vitro ³¹P MR Chemical Shifts of In Vivo-Detectable Metabolites at 3T as a Basis Set for a Pilot Evaluation of Skeletal Muscle and Liver ³¹P Spectra with LCModel Software

Molecules, 2021
Most in vivo 31P MR studies are realized on 3T MR systems that provide sufficient signal intensity for prominent phosphorus metabolites. The identification of these metabolites in the in vivo spectra is performed by comparing their chemical shifts with ...

Beyond Conventional Approaches: The Revolutionary Role of Nanoparticles in Breast Cancer

MedComm – Biomaterials and Applications, Volume 4, Issue 2, June 2025.
This review explores integrated approach of nanotechnology to breast cancer diagnosis and treatment. We highlight imaging techniques for tumor detection and biomarker analysis in biological samples for early diagnosis. Advanced therapies, including targeted drug delivery and antibody‐drug conjugates, enable precise medication transport to cancer cells,

Reduced Hepatic Bilirubin Uridine Diphosphate Glucuronyl Transferase and Uridine Diphosphate Glucose Dehydrogenase Activity in the Human Fetus [PDF]

Pediatric Research, 1978
Hepatic bilirubin uridine diphosphate glucuronyl transferase (UDPG-T) activity was 0.14 and 0.22 units in two fetuses aged 17 and 22 weeks, respectively, and less than 0.1 unit in 15 fetuses, aged 8--19 weeks compared to 0.68--1.99 units in 21 normal adults.
