Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Cysteine depletion sensitizes prostate cancer cells to agents that enhance DNA damage and to immune checkpoint inhibition

Journal of Experimental & Clinical Cancer Research, 2023
Background Prostate Cancer (PCa) represents one of the most commonly diagnosed neoplasms in men and is associated with significant morbidity and mortality.

Processing of thymine glycol in a clustered DNA damage site: mutagenic or cytotoxic. [PDF]

Nucleic Acids Res, 2009
Localized clustering of damage is a hallmark of certain DNA-damaging agents, particularly ionizing radiation. The potential for genetic change arising from the effects of clustered damage sites containing combinations of AP sites, 8-oxo-7,8-dihydroguanine (8-oxoG) or 5,6-dihydrothymine is high.

Chemical Aspects of Clustered DNA Damage Induction by Ionising Radiation

Radiation Protection Dosimetry, 2002
Ionising radiation induces a variety of chemical modifications to DNA, ranging from simple, isolated lesions to clustered DNA damage, in which two or more lesions are formed within a few tens of base pairs by a single radiation track. Multiple lesions, e.g. tandem lesions and amplification of damage, may also be induced in DNA by reaction with a single

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Identification of gastric cancer subtypes based on pathway clustering

npj Precision Oncology, 2021
Gastric cancer (GC) is highly heterogeneous in the stromal and immune microenvironment, genome instability (GI), and oncogenic signatures. However, a classification of GC by combining these features remains lacking.

Analysis for complexity of clustered DNA damage generated by heavy ion beams [PDF]

Nucleic Acids Symposium Series, 2008
Among numerous DNA damaging factors, ionizing radiation produces the damage showing very unique structure. Since ionizing radiation passes through a target DNA as a beam, the respective induced lesions locate close together around the track. Such damage aggregation on target DNA called "clustered DNA damage" is thought to be a major cause of the ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Clusters of S1 Nuclease-Hypersensitive Sites Induced In Vivo by DNA Damage [PDF]

Molecular and Cellular Biology, 1997
DNA end-labeling procedures were used to analyze both the frequency and distribution of DNA strand breaks in mammalian cells exposed or not to different types of DNA-damaging agents. The 3' ends were labeled by T4 DNA polymerase-catalyzed nucleotide exchange carried out in the absence or presence of Escherichia coli endonuclease IV to cleave abasic ...
