Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Purine salvage promotes treatment resistance in H3K27M-mutant diffuse midline glioma

Cancer & Metabolism
Background Diffuse midline gliomas (DMG), including diffuse intrinsic pontine gliomas (DIPGs), are a fatal form of brain cancer. These tumors often carry a driver mutation on histone H3 converting lysine 27 to methionine (H3K27M).

Case report: Whole exome sequencing identifies a novel variant in the HPRT1 gene in a male with developmental delay

Frontiers in Genetics
Lesch-Nyhan syndrome (LNS, OMIM #300322) is a rare X-linked genetic disorder caused by variants in the HPRT1 gene, which codes for the Hypoxanthine-guanine phosphoribosyltransferase (HGPRT).

A Golgi study of neuronal architecture in a genetic mouse model for Lesch–Nyhan disease

Neurobiology of Disease, 2005
Lesch–Nyhan disease (LND) is an inherited disorder associated with deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT), an enzyme essential for purine recycling.

Xanthine oxidase activity in thiopurine curative Chinese inflammatory bowel disease patients

Pharmacology Research & Perspectives, 2021
Xanthine oxidase (XO) competes with thiopurine S‐methyltransferase (TPMT) and hypoxanthine guanine phosphoribosyltransferase (HPRT) to metabolize azathioprine (AZA)/6‐mercaptopurine (6‐MP) in vivo.

Leishmania promastigotes evade interleukin 12 (IL-12) induction by macrophages and stimulate a broad range of cytokines from CD4+ T cells during initiation of infection. [PDF]

, 1994
Leishmania major are intramacrophage parasites whose eradication requires the induction of T helper 1 (Th1) effector cells capable of activating macrophages to a microbicidal state.

Subunit Molecular Weight of Human Hypoxanthine-Guanine Phosphoribosyltransferase

Journal of Biological Chemistry, 1974
Abstract The subunit molecular weight of hypoxanthine-guanine phosphoribosyltransferase is reported to be 25,000 for the Chinese hamster enzyme (Olsen, A. S., and Milman, G. (1974) J. Biol. Chem. 249, 4030) and 34,500 for the human enzyme (Arnold, W. J., and Kelley, W. N. (1971) J. Biol. Chem. 246, 7398–7404).

The In Vitro Transgenic Rodent Assay in Primary MutaMouse Hepatocytes Compared to the Mammalian Cell Gene Mutation Assay Using the HPRT Gene

Environmental and Molecular Mutagenesis, Volume 67, Issue 1-2, January‐February 2026.
ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.

IMPDH2 and HPRT expression and a prognostic significance in preoperative and postoperative patients with osteosarcoma

Scientific Reports, 2021
Osteosarcoma is one of the most aggressive bone tumors in children and adolescents. Development of effective therapeutic options is still lacking due to the complexity of the genomic background.
