Differential gene expression toward species of Aristolochia impairing the performance of the Troidini butterfly Battus polydamas

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 696-707, July 2025.
We studied the response of Battus polydamas (Papilionidae) larvae fed on Aristolochia ringens (containing several diterpenes) and Aristolochia gigantea (containing sesquiterpenes and acyclic monoterpenoids but no diterpenoids or aristolochic acids). We assessed larval performance on fitness components such as survival and differential gene expression ...

Human γδ T Cell Function Is Impaired Upon Mevalonate Pathway Inhibition

open access: yesImmunology, Volume 175, Issue 3, Page 300-322, July 2025.
Mevalonate pathway is important for the effector function of gammadelta T cells. Inhibition of the pathway in vivo and in vitro impairs cytokine and cytotoxic molecule production by mainly affecting protein prenylation and disturbing intracellular signalling in Vdelta2 T cells. Created with Biorender.

Screening of prenyldiphosphate mimetics for their potential to inhibit 4-hydroxybenzoate oligoprenyl transferase [PDF]

open access: yes, 2017
4-Hydroxybenzoat-Oligoprenyl-Transferase (UbiA-Prenyltransferase) ist ein wichtiges Enzym in der Ubichinon-Biosynthese von E. coli. Es katalysiert die Prenylierung von 4-Hydroxybenzoat (4-HB) an Position 3 zu 3-Oligoprenyl-4-Hydroxybenzoat ...

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont

open access: yesEnvironmental Microbiology, Volume 27, Issue 6, June 2025.
This analysis of 794 publicly available lichen shotgun metagenomic datasets, covering 467 unique lichen species from 34 countries, revealed that lichens are complex holobionts. They harbour a variety of fungal, algal, and bacterial players with remarkable biosynthetic capabilities.

Impact of Mutational Status on Intracellular Effects of Cell‐Permeable CaaX Peptides in Pancreatic Cancer Cells

open access: yesChemBioChem, Volume 26, Issue 10, May 27, 2025.
This work deals with intracellular effects of cell‐permeable CaaX‐peptides, designed to influence prenylated proteins like KRas. The results show that after CaaX‐1 treatment, not only KRas expression and signaling are specifically altered in mutated pancreatic cancer cells, but also plasma membrane localization of KRas is affected.

EXPANDING THE POTENTIAL PRENYLOME: PRENYLATION OF SHORTENED TARGET SUBSTRATES BY FTASE AND DEVELOPMENT OF FRET-BASED SYSTEM FOR DETECTING POTENTIALLY “SHUNTED” PROTEINS [PDF]

open access: yes, 2020
Protein prenylation is a posttranslational modification involving the attachment of a C15 or C20 isoprenoid group to a cysteine residue near the C-terminus of the target substrate by protein farnesyltransferase (FTase) or protein ...

Disturbing Cholesterol/Sphingolipid Metabolism by Squalene Epoxidase Arises Crizotinib Hepatotoxicity

open access: yesAdvanced Science, Volume 12, Issue 14, April 10, 2025.
Crizotinib induces excessive accumulation of squalene epoxidase (SQLE) by blocking its autophagic degradation. This accumulation disrupts cholesterol and sphingolipid metabolism, leading to hepatic steatosis or hepatocyte apoptosis, respectively. Autophagy activators, such as metformin, or SQLE enzymatic inhibitors, like terbinafine, possesses the ...

Valproic acid induces ferroptosis and suppresses the proliferation of MDA-MB-231 cells by targeting FDFT1

open access: yesFrontiers in Pharmacology
IntroductionValproic acid (VPA) constitutes a branched-chain, short-chain fatty acid that serves as an antiepileptic medication. It has been increasingly recognized that VPA has presented potential anti-tumor properties, including breast cancer. However,

The Role of Cholesterol Metabolism and Its Regulation in Tumor Development

open access: yesCancer Medicine, Volume 14, Issue 7, April 2025.
ABSTRACT Background Within the tumor microenvironment, tumor cells undergo metabolic reprogramming of cholesterol due to intrinsic cellular alterations and changes in the extracellular milieu. Furthermore, cholesterol reprogramming within this microenvironment influences the immune landscape of tumors, facilitating immune evasion and consequently ...

Identification of a Novel Class of Farnesylation Targets by Structure-Based Modeling of Binding Specificity [PDF]

open access: yes, 2011
Farnesylation is an important post-translational modification catalyzed by farnesyltransferase (FTase). Until recently it was believed that a C-terminal CaaX motif is required for farnesylation, but recent experiments have revealed larger substrate ...
