SAVER: gene expression recovery for single-cell RNA sequencing

…, R Bonasio, JI Murray, A Raj, M Li, NR Zhang - Nature …, 2018 - nature.com
In single-cell RNA sequencing (scRNA-seq) studies, only a small fraction of the transcripts
present in each cell are sequenced. This leads to unreliable quantification of genes with low …

[HTML][HTML] Bulk tissue cell type deconvolution with multi-subject single-cell expression reference

X Wang, J Park, K Susztak, NR Zhang, M Li - Nature communications, 2019 - nature.com
Abstract Knowledge of cell type composition in disease relevant tissues is an important step
towards the identification of cellular targets of disease. We present MuSiC, a method that …

A modified Bayes information criterion with applications to the analysis of comparative genomic hybridization data

NR Zhang, DO Siegmund - Biometrics, 2007 - academic.oup.com
In the analysis of data generated by change-point processes, one critical challenge is to
determine the number of change-points. The classic Bayes information criterion (BIC) statistic …

[HTML][HTML] Organization of the human intestine at single-cell resolution

…, K Cao, S Chen, W Zhang, E Monte, NR Zhang… - Nature, 2023 - nature.com
The intestine is a complex organ that promotes digestion, extracts nutrients, participates in
immune surveillance, maintains critical symbiotic relationships with microbiota and affects …

[PDF][PDF] Opposing functions of interferon coordinate adaptive and innate immune responses to cancer immune checkpoint blockade

…, D Ye, KL Nathanson, CH June, EJ Wherry, NR Zhang… - Cell, 2019 - cell.com
Interferon-gamma (IFNG) augments immune function yet promotes T cell exhaustion through
PDL1. How these opposing effects are integrated to impact immune checkpoint blockade (…

[HTML][HTML] BRCA locus-specific loss of heterozygosity in germline BRCA1 and BRCA2 carriers

…, S Yu, Y Jiang, H Chen, NR Zhang… - Nature …, 2017 - nature.com
Complete loss of BRCA1 or BRCA2 function is associated with sensitivity to DNA damaging
agents. However, not all BRCA1 and BRCA2 germline mutation-associated tumors respond. …

Assessing intratumor heterogeneity and tracking longitudinal and spatial clonal evolutionary history by next-generation sequencing

…, Y Qiu, AJ Minn, NR Zhang - Proceedings of the …, 2016 - National Acad Sciences
Cancer is a disease driven by evolutionary selection on somatic genetic and epigenetic
alterations. Here, we propose Canopy, a method for inferring the evolutionary phylogeny of a …

Bayesian variable selection in structured high-dimensional covariate spaces with applications in genomics

F Li, NR Zhang - Journal of the American statistical association, 2010 - Taylor & Francis
… We follow the approach suggested in Zhang, Wildermuth, and Speed (2008) and use the
scores of the first principal component of the data, the loadings of which are plotted versus time …

Detecting simultaneous changepoints in multiple sequences

NR Zhang, DO Siegmund, H Ji, JZ Li - Biometrika, 2010 - academic.oup.com
… One is a multi-sequence version of the Bayesian information criterion for model selection
that we used for single sequence analysis (Zhang & Siegmund, 2007). This has the potential to …

[PDF][PDF] The interferon-stimulated gene RIPK1 regulates cancer cell intrinsic and extrinsic resistance to immune checkpoint blockade

…, IE Brodsky, MS Jordan, DG Gilliland, NR Zhang… - Immunity, 2022 - cell.com
Interferon-gamma (IFN-γ) has pleiotropic effects on cancer immune checkpoint blockade (ICB),
including roles in ICB resistance. We analyzed gene expression in ICB-sensitive versus …
