Music Interventions for Stress Reduction

, 2021
The goal of this dissertation is to contribute to the body of scientific knowledge on music interventions for stress reduction. To cope with the negative impact of stress, millions of people around the world use tranquilizing medication, which in turn is associated with numerous contraindications and negative side effects. Therefore, there is an urgent

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Free Radicals in Health and Disease

MedComm
Free radicals, molecules with unpaired electrons, are double‐edged swords. While they may cause damages to cells and threaten human health, they play essential roles in cellular signaling toward mitochondrial and immune homeostasis.

Effects of CO2 and H2 limitations on Methanococcus maripaludis

Microbiology Spectrum
Hydrogenotrophic methanogens play a key role in anaerobic ecosystems by catalyzing the bioconversion of hydrogen (H2) and carbon dioxide (CO2) into methane (CH4) and water.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Mitochondrial NADH-redox inflexibility constrains genomic and epigenetic stability in pluripotent stem cells

The EMBO Journal
The electron transport chain (ETC) is essential for NAD+ regeneration and proliferation. While many cell types tolerate ETC inhibition when pyruvate or aspartate is supplied, pluripotent stem cells (PSCs) enter a reversible paused state even at abundant ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using
