Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Circular RNA is expressed across the eukaryotic tree of life. [PDF]

open access: yesPLoS ONE, 2014
An unexpectedly large fraction of genes in metazoans (human, mouse, zebrafish, worm, fruit fly) express high levels of circularized RNAs containing canonical exons.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

open access: yesFEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life [PDF]

open access: yes, 2010
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication of RNA and DNA, understanding the origin of ...

Bioinformatic Analysis of Circular RNA Expression

open access: yes, 2021
Circular RNAs (circRNAs) are stable RNA molecules generated by backsplicing that play regulatory functions through interaction with other RNA and proteins, as well as by encoding peptides.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

CircSeqAlignTk: An R package for end-to-end analysis of RNA-seq data for circular genomes [version 1; peer review: 1 approved, 2 approved with reservations]

open access: yesF1000Research, 2022
RNA sequencing (RNA-seq) technology has now become one of the standard tools for studying biological mechanisms at the transcriptome level. Advances in RNA-seq technology have led to the emergence of a large number of publicly available tools for RNA-seq

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Circular RNA Expression Profile in Cervical Cancer and Construction of the Circular RNA‑MicroRNA‑Messenger RNA Regulatory Network

open access: yesКреативная хирургия и онкология
Introduction. Cervical cancer (CC) remains the most common cancer in women worldwide. However, effective and specific biomarkers for the diagnosis and prognosis of cervical cancer are yet to be found.

Engineering circular RNA regulators to specifically promote circular RNA production

open access: yesTheranostics, 2021
Background: A large number of circular RNAs (circRNAs) have been discovered in the mammalian transcriptome with high abundance, which play vital roles in gene regulation, thereby participating in the development of multiple diseases. However, the biogenesis, regulation, and especially manipulation of circRNAs still remain largely unknown.
