SPRTN is involved in hepatocellular carcinoma development through the ER stress response.

Endoplasmic reticulum (ER) stress, prompted by the accumulation of misfolded or unfolded proteins, triggers the activation of the unfolded protein response (UPR) pathway to restore ER homeostasis. This stress response is implicated in the development of hepatocellular carcinoma (HCC). A biallelic mutation in SPRTN is currently the only known single-gene mutation implicated in the early onset of HCC.

Seasonality of Polyaromatic Hydrocarbons (PAHs) and Their Derivatives in PM from Ljubljana, Combustion Aerosol Source Apportionment, and Cytotoxicity of Selected Nitrated Polyaromatic Hydrocarbons (NPAHs).

Airborne particulate matter (PM) is a vector of many toxic pollutants, including polyaromatic hydrocarbons (PAHs) and their derivatives. Especially harmful is the fine fraction (PM), which penetrates deep into the lungs during inhalation and causes various diseases. Amongst PM components with toxic potential are nitrated PAHs (NPAHs), knowledge of which is still rudimentary.

Centaurea triumfetii essential oil chemical composition, comparative analysis, and antimicrobial activity of selected compounds.

The essential oils from the Centaurea genus are well known for their pharmacological properties. The most abundant and dominant chemical components in Centaurea essential oils are ß-caryophyllene, hexadecanoic acid, spathulenol, pentacosane, caryophyllene oxide, and phytol. However, whether these dominant components are the key drivers for observed antimicrobial activity remains unclear.

Phytochemical and Cytogenetic Study of Two Centaurea Species from Croatia: the Particular Case of Diploid and Tetraploid C. salonitana.

Natural wild populations of C. rupestris and C. salonitana were studied to determine possible relationships between the volatile oil (VO) composition and ploidy level.

Mechanism of -Nerolidol-Induced Bladder Carcinoma Cell Death.

Nerolidol is a naturally occurring sesquiterpene alcohol with multiple properties, including antioxidant, antibacterial, and antiparasitic activities. A few studies investigating the antitumor properties of nerolidol have shown positive results in both cell culture and mouse models. In this study, we investigated the antitumor mechanism of -nerolidol in bladder carcinoma cell lines.

SPRTN-dependent DPC degradation precedes repair of damaged DNA: a proof of concept revealed by the STAR assay.

DNA-protein crosslinks (DPCs), formed by the covalent conjugation of proteins to DNA, are toxic lesions that interfere with DNA metabolic processing and transcription. The development of an accurate biochemical assay for DPC isolation is a priority for the mechanistic understanding of their repair. Here, we propose the STAR assay for the direct quantification of DPCs, sensitive to physiologically relevant treatment conditions.

Direct and cost-effective method for histone isolation from cultured mammalian cells.

Histones are an essential part of nucleosomes that regulate chromatin structure and function. Histone exchanges and modifications represent a scaffold for DNA transcription, repair, and replication. Studying histones and histone code is an important and fast-developing branch of epigenetic science.
