Computational modeling to elucidate molecular mechanisms of epigenetic memory

open access: yes, 2015
How do mammalian cells that share the same genome exist in notably distinct phenotypes, exhibiting differences in morphology, gene expression patterns, and epigenetic chromatin statuses?

Conversion of Transplanted Mature Hepatocytes into Afp+ Reprogrammed Cells for Liver Regeneration After Injury

open access: yesAdvanced Science, EarlyView.
Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.

Chromatin: a tunable spring at work inside chromosomes

open access: yes, 2001
This paper focuses on mechanical aspects of chromatin biological functioning. Within a basic geometric modeling of the chromatin assembly, we give for the first time the complete set of elastic constants (twist and bend persistence lengths, stretch ...

Chromatin accessibility underlies synthetic lethality of SWI/SNF subunits in ARID1A-mutant cancers. [PDF]

open access: yes, 2017
ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, is frequently mutated in cancer. Deficiency in its homolog ARID1B is synthetically lethal with ARID1A mutation.

Structural basis of the nucleosome transition during RNA polymerase II passage

open access: yesScience, 2018
Nucleosomal DNA transcription In eukaryotes, the basic chromatin unit nucleosome stalls RNA polymerase II (RNAPII) when it transcribes genetic information on DNA. Using cryo–electron microscopy, Kujirai et al.

Bioinformatics‐based discovery of the involvement of PSAT1 in mediating the anti‐lung adenocarcinoma activity of triptolide

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Transcriptome sequencing was performed on tumor tissues from triptolide‐treated tumor‐bearing mice. The sequencing results were integrated with data from public databases for comprehensive analysis, and potential regulatory targets of triptolide were identified.

Toward a molecular understanding of yeast silent chromatin : roles for H4K16 acetylation and the Sir3 C-terminus [PDF]

open access: yes, 2012
Discrete regions of the eukaryotic genome assume a heritable chromatin structure that is refractory to gene expression. In budding yeast, silent chromatin is characterized by the loading of the Silent Information Regulatory (Sir) proteins (Sir2, Sir3 and

Simultaneous measurement of chromatin accessibility, DNA methylation, and nucleosome phasing in single cells

open access: yesbioRxiv, 2017
Gaining insights into the regulatory mechanisms that underlie the transcriptional variation observed between individual cells necessitates the development of methods that measure chromatin organization in single cells. Here I adapted Nucleosome Occupancy

Autoantibody Response Toward Chromatin in Patients With Juvenile Idiopathic Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Patients with juvenile idiopathic arthritis (JIA) frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in patients with JIA remains elusive.

SWI/SNF-like chromatin remodeling factor Fun30 supports point centromere function in S. cerevisiae [PDF]

open access: yes, 2011
Budding yeast centromeres are sequence-defined point centromeres and are, unlike in many other organisms, not embedded in heterochromatin. Here we show that Fun30, a poorly understood SWI/SNF-like chromatin remodeling factor conserved in humans ...
