Simultaneous profiling of 3D genome structure and DNA methylation in single human cells

DS Lee, C Luo, J Zhou, S Chandran, A Rivkin… - Nature …, 2019 - nature.com
Dynamic three-dimensional chromatin conformation is a critical mechanism for gene regulation
during development and disease. Despite this, profiling of three-dimensional genome …

[HTML][HTML] Disruption of chromatin folding domains by somatic genomic rearrangements in human cancer

KC Akdemir, VT Le, S Chandran, Y Li, RG Verhaak… - Nature …, 2020 - nature.com
Chromatin is folded into successive layers to organize linear DNA. Genes within the same
topologically associating domains (TADs) demonstrate similar expression and histone-…

Structural variants drive context-dependent oncogene activation in cancer

Z Xu, DS Lee, S Chandran, VT Le, R Bump, J Yasis… - Nature, 2022 - nature.com
Higher-order chromatin structure is important for the regulation of genes by distal regulatory
sequences 1 , 2 . Structural variants (SVs) that alter three-dimensional (3D) genome …

Incorporation of a nucleoside analog maps genome repair sites in postmitotic human neurons

…, II Nitulescu, G Chou, EC Tsui, JR Jones, S Chandran… - Science, 2021 - science.org
Neurons are the longest-lived cells in our bodies and lack DNA replication, which makes
them reliant on a limited repertoire of DNA repair mechanisms to maintain genome fidelity. …

[HTML][HTML] Time-restricted feeding restores muscle function in Drosophila models of obesity and circadian-rhythm disruption

JE Villanueva, C Livelo, AS Trujillo, S Chandran… - Nature …, 2019 - nature.com
Pathological obesity can result from genetic predisposition, obesogenic diet, and circadian
rhythm disruption. Obesity compromises function of muscle, which accounts for a majority of …

[HTML][HTML] Circular extrachromosomal DNA promotes tumor heterogeneity in high-risk medulloblastoma

…, KL Hung, JT Lange, SR Dehkordi, S Chandran… - Nature …, 2023 - nature.com
Circular extrachromosomal DNA (ecDNA) in patient tumors is an important driver of oncogenic
gene expression, evolution of drug resistance and poor patient outcomes. Applying …

Dynamic regulation of histone modifications and long-range chromosomal interactions during postmitotic transcriptional reactivation

H Kang, MN Shokhirev, Z Xu, S Chandran… - Genes & …, 2020 - genesdev.cshlp.org
During mitosis, transcription of genomic DNA is dramatically reduced, before it is reactivated
during nuclear reformation in anaphase/telophase. Many aspects of the underlying …

[HTML][HTML] 3D genome mapping identifies subgroup-specific chromosome conformations and tumor-dependency genes in ependymoma

…, M Pagadala, R Bump, S Chandran… - Nature …, 2023 - nature.com
Ependymoma is a tumor of the brain or spinal cord. The two most common and aggressive
molecular groups of ependymoma are the supratentorial ZFTA-fusion associated and the …

[HTML][HTML] Author Correction: Disruption of chromatin folding domains by somatic genomic rearrangements in human cancer

KC Akdemir, VT Le, S Chandran, Y Li, RG Verhaak… - nature genetics, 2023 - nature.com
In the published version of this paper, the members of the Pan-Cancer Analysis of Whole
Genomes (PCAWG) Consortium were listed in the Supplementary Information; however, these …

Increasing autophagy and blocking Nrf2 suppress laminopathy‐induced age‐dependent cardiac dysfunction and shortened lifespan

…, GH Young, DE Cryderman, S Chandran… - Aging cell, 2018 - Wiley Online Library
Mutations in the human LMNA gene cause a collection of diseases known as laminopathies.
These include myocardial diseases that exhibit age‐dependent penetrance of …
