Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

CircRNA: A new class of targets for gastric cancer drug resistance therapy

open access: yesPathology and Oncology Research, 2023
Gastric cancer (GC) is one of the most common malignancies worldwide. Patients with advanced GC need palliative care to ensure survival. This includes the use of chemotherapy agents, such as cisplatin, 5-fluorouracil, oxaliplatin, paclitaxel, and ...

Evolution of YidC/Oxa1/Alb3 insertases: three independent gene duplications followed by functional specialization in bacteria, mitochondria and chloroplasts [PDF]

open access: yes, 2011
Members of the YidC/Oxa1/Alb3 protein family facilitate the insertion, folding and assembly of proteins of the inner membranes of bacteria and mitochondria and the thylakoid membrane of plastids.

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Pathogenic mechanisms and the potential clinical value of circFoxo3 in cancers

open access: yesMolecular Therapy: Nucleic Acids, 2021
Circular RNAs (circRNAs) are covalently closed circular structures that can function in various physiological and pathological processes by acting as microRNA (miRNA) sponges, RNA-binding protein (RBP) sponges, mRNA transcriptional regulators, and ...

Computational identification of transcription factor binding sites by functional analysis of sets of genes sharing overrepresented upstream motifs [PDF]

open access: yes, 2004
BACKGROUND: Transcriptional regulation is a key mechanism in the functioning of the cell, and is mostly effected through transcription factors binding to specific recognition motifs located upstream of the coding region of the regulated gene.

Peroxisome biogenesis and peroxisome biogenesis disorders

open access: yesFEBS Letters, 2000
Peroxisome assembly in mammals requires more than 15 genes. Two isoforms of the peroxisome targeting signal type 1 (PTS1) receptor, Pex5pS and Pex5pL, are identified in mammals. Pex5pS and Pex5pL bind PTS1 proteins. Pex5pL, but not Pex5pS, directly interacts with the PTS2 receptor, Pex7p, carrying its cargo PTS2 protein in the cytosol.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

open access: yesFEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Tail-Anchored Protein Insertion by a Single Get1/2 Heterodimer

open access: yesCell Reports, 2017
The Get1/2 transmembrane complex drives the insertion of tail-anchored (TA) proteins from the cytosolic chaperone Get3 into the endoplasmic reticulum membrane.
