Massively multiplex single-molecule oligonucleosome footprinting

open access: yeseLife, 2020
Our understanding of the beads-on-a-string arrangement of nucleosomes has been built largely on high-resolution sequence-agnostic imaging methods and sequence-resolved bulk biochemical techniques. To bridge the divide between these approaches, we present

Cancer‐Like Fragmentomic Characteristics of Somatic Variants in Cell‐Free DNA

open access: yesAdvanced Science, EarlyView.
We report that in non‐cancerous subjects, cell‐free (cfDNA) molecules harboring somatic variants exhibit cancer‐like fragmentomic characteristics associated with clonal hematopoiesis. Importantly, these somatic variant‐associated fragmentomic aberrations are more pronounced in cancer patients. Leveraging such somatic variant‐associated signals in cfDNA,

Colorectal carcinoma: nucleosomes, carcinoembryonic antigen and ca 19-9 as apoptotic markers; a comparative study

open access: yesJournal of Biomedical Science, 2011
Background Colorectal carcinoma is a common and often fatal disease in which methods of early detection and monitoring are essential. The present study was conducted for measuring serum levels of nucleosomes, carcinoembryonic antigen (CEA) and CA 19-9 in

TP53BP2 Promotes Placental Autophagy and Preeclampsia via G9a and DNMT1 Cooperatively Modulating E2F1

open access: yesAdvanced Science, EarlyView.
G9a, and DNA Methyltransferase1 (DNMT1) cooperatively modulates E2F1 on the promoter of tumor suppressor p53‐binding protein 2 (TP53BP2) increased autophagy in preeclampsia. TP53BP2 promotes autophagy in trophoblasts through DNA methylation and H3K9me2‐mediated transcriptional regulation.

Chromatin Profiles of Chromosomally Integrated Human Herpesvirus-6A

open access: yesFrontiers in Microbiology, 2019
Human herpesvirus-6A (HHV-6A) and 6B (HHV-6B) are two closely related betaherpesviruses that are associated with various diseases including seizures and encephalitis.

CENP-A nucleosomes localize to transcription factor hotspots and subtelomeric sites in human cancer cells

open access: yesEpigenetics & Chromatin, 2015
BackgroundThe histone H3 variant CENP-A is normally tightly regulated to ensure only one centromere exists per chromosome. Native CENP-A is often found overexpressed in human cancer cells and a range of human tumors. Consequently, CENP-A misregulation is

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.

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.

Cytopathologic Features of Metastatic Malignant Mesothelioma With SMARCB1 (INI‐1) Deficient Diagnosed by Ultrasound‐Guided Fine‐Needle Aspiration: A Case Report

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Malignant mesothelioma (MM) is a rare yet aggressive neoplasm that arises from mesothelial cells lining the thoracic and abdominal cavities, the pericardium, and the tunica testis. Characterized by rapid progression, high invasiveness, and a poor prognosis, MM poses significant clinical challenges. SMARCB1, also referred to as INI‐1, hSNF5, or

Asymmetric nucleosomes flank promoters in the budding yeast genome

open access: yesGenome Research, 2015
Nucleosomes in active chromatin are dynamic, but whether they have distinct structural conformations is unknown. To identify nucleosomes with alternative structures genome-wide, we used H4S47C-anchored cleavage mapping, which revealed that 5% of budding ...
