Beyond the Mevalonate Pathway: Control of Post-Prenylation Processing by Mutant p53

Frontiers in Oncology, 2020
Missense mutations in the TP53 gene are among the most frequent alterations in human cancer. Consequently, many tumors show high expression of p53 point mutants, which may acquire novel activities that contribute to develop aggressive tumors.

Harnessing Repurposed Drugs to Enhance Temozolomide Efficacy in Glioblastoma

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Glioblastoma (GB) is the most aggressive primary malignant brain tumor in adults and remains associated with poor survival despite surgical resection followed by radiotherapy and temozolomide (TMZ) chemotherapy. Intrinsic and acquired resistance to TMZ, including MGMT‐dependent DNA repair and activation of pro‐survival pathways ...

Antitumor Activity of Some Prenylated Xanthones

Pharmaceuticals, 2009
Pyranoxanthones 6-8 were obtained by dehydrogenation of the respective dihydropyranoxanthones 3-5 with DDQ in dry dioxane. Two prenylated xanthones 10,11 were obtained from the reaction of 1-hydroxyxanthone (9) with prenyl bromide in alkaline medium, or ...

Discontinuing Long‐Term Denosumab in Treating Fragile Bone: Why, for Whom, and How?

Clinical Pharmacology &Therapeutics, Volume 120, Issue 2, Page 334-344, August 2026.
Discontinuation of denosumab (Dmab) may be necessary due to adverse events or an unfavorable long‐term risk–benefit profile. However, accumulating evidence demonstrates pronounced rebound phenomena after withdrawal, most notably a marked increase in multiple vertebral fractures, and, in some reports, elevated mortality.

Multiple Factors Contribute to Inefficient Prenylation of Rab27a in Rab Prenylation Diseases [PDF]

Journal of Biological Chemistry, 2003
Post-translational geranylgeranylation of Rab GT-Pases is essential for their membrane association and function as regulators of intracellular vesicular transport. The reaction is catalyzed by Rab geranylgeranyltransferase (RGGT) and is assisted by the Rab escort proteins (REP), which form stable complexes with newly synthesized GDP-bound Rabs.

SNHG15 Positively Regulates Influenza Virus Infection Through Its Association With miR‐153 and RABL2A

Journal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT Influenza viruses cause seasonal epidemics, and current vaccines do not fully protect against them. This study focuses on long non‐coding RNAs (lncRNAs), which are RNA molecules that do not code for proteins but play crucial roles in various biological processes. We identified 17 lncRNAs altered by the influenza virus.

Defective Protein Prenylation in a Spectrum of Patients With Mevalonate Kinase Deficiency

Frontiers in Immunology, 2019
The rare autoinflammatory disease mevalonate kinase deficiency (MKD, which includes HIDS and mevalonic aciduria) is caused by recessive, pathogenic variants in the MVK gene encoding mevalonate kinase.

Cardiovascular Diseases and Cancer: Convergent Proteostasis Networks at the Crossroads of Mechanisms and Therapeutic Opportunities

MedComm, Volume 7, Issue 8, August 2026.
The disruption of proteostasis, encompassing the ubiquitin–proteasome system, autophagy, UPR/ER stress, and chaperone function, represents a fundamental mechanism shared by both cancer and cardiovascular diseases. While these pathways frequently facilitate tumor progression, they are crucial for maintaining proteostasis in cardiac tissue. Consequently,

Inclusion of PF68 Surfactant Improves Stability of rAAV Titer when Passed through a Surgical Device Used in Retinal Gene Therapy

Molecular Therapy: Methods & Clinical Development, 2020
Recent advances in recombinant adeno-associated virus (rAAV) gene therapy for choroideremia show gene replacement to be a promising approach. It is, however, well known that contact of vector solution with plastic materials in the surgical device may ...

Targeting RANKL Prevents Bone Loss, Improves Muscle Function and Extends Lifespan in Progeroid Mice

Aging Cell, Volume 25, Issue 8, August 2026.
Targeting of RANKL by genetic and pharmacological approaches ameliorates key features of the progeroid phenotype in Zmpste24−/− mice. RANKL intervention restores bone mass, improves muscle phenotype, and extends survival. These findings support further exploration of RANKL‐targeted therapies for Hutchinson‐Gilford progeria syndrome.
