Type 1 polyisoprenoid diphosphate phosphatase modulates geranylgeranyl-mediated control of HMG CoA reductase and UBIAD1

eLife, 2021
UbiA prenyltransferase domain-containing protein-1 (UBIAD1) utilizes geranylgeranyl pyrophosphate (GGpp) to synthesize the vitamin K2 subtype menaquinone-4. The prenyltransferase has emerged as a key regulator of sterol-accelerated, endoplasmic reticulum

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, EarlyView.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...

Mevalonate biosynthesis pathway regulates the development and survival of brown adipocytes

iScience, 2023
Summary: The high thermogenic activity of brown adipose tissue (BAT) has received considerable attention. Here, we demonstrated the role of the mevalonate (MVA) biosynthesis pathway in the regulation of brown adipocyte development and survival.

Statins inhibit blastocyst formation by preventing geranylgeranylation [PDF]

Molecular Human Reproduction, 2016
Statins, inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase of the mevalonate pathway and prescription drugs that treat hypercholesterolemia, compromise preimplantation mouse development via modulation of HIPPO signaling.HMG-CoA reductase activity is required for trophectoderm specification, namely blastocyst cavity formation and ...

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

Conserved statin-mediated activation of the p38-MAPK pathway protects Caenorhabditis elegans from the cholesterol-independent effects of statins

Molecular Metabolism, 2020
Objective: Statins are a group of medications that reduce cholesterol synthesis by inhibiting the activity of HMG-CoA reductase, a key enzyme in the mevalonate pathway. The clinical use of statins to lower excess cholesterol levels has revolutionized the

Deficient Geranylgeranylation of Ram/Rab27 in Choroideremia [PDF]

Journal of Biological Chemistry, 1995
Choroideremia, an X-linked form of retinal degeneration, results from defects in the Rab escort protein-1 (REP-1) gene. REP-1 and REP-2 assist in the attachment of geranylgeranyl groups to Rab GTPases, a modification essential for their action as molecular switches regulating intracellular vesicular transport.

Convergent Metabolic Pathways in MASH Therapeutics: An AMPK‐Centric Analysis

Journal of Cellular and Molecular Medicine, Volume 30, Issue 2, January 2026.
ABSTRACT Metabolic dysfunction‐associated steatohepatitis (MASH) is a leading cause of liver‐related morbidity driven by systemic metabolic dysregulation. The recent approval of resmetirom and the clinical success of GLP‐1 receptor agonists have heralded a new era in MASH therapy, yet a convergent understanding of the complex mechanisms of these ...

A quantitative method to measure geranylgeranyl diphosphate (GGPP) and geranylgeranyl monophosphate (GGP) in tomato (Solanum lycopersicum) fruit

Plant Methods, 2023
Abstract Background Isoprenoids are a very large class of metabolites playing a key role in plant physiological processes such as growth, stress resistance, fruit flavor, and color. In chloroplasts and chromoplasts, the diterpene compound geranylgeranyl diphosphate (GGPP) is the metabolic ...
