Personalized Evaluation of Biomarker Value: A Cost-Benefit Perspective.

Statistics in biosciences

Huang Y, Laber E.
PMID: 27446505
Stat Biosci. 2016;8:43-65. doi: 10.1007/s12561-014-9122-4. Epub 2014 Nov 21.

For a patient who is facing a treatment decision, the added value of information provided by a biomarker depends on the individual patient's expected response to treatment with and without the biomarker, as well as his/her tolerance of disease...

Structured detection of interactions with the directed lasso.

Statistics in biosciences

Pashova H, LeBlanc M, Kooperberg C.
PMID: 29292402
Stat Biosci. 2017 Dec;9(2):676-691. doi: 10.1007/s12561-016-9184-6. Epub 2016 Nov 29.

When considering low-dimensional gene-treatment or gene-environment interactions we might suspect groups of genes to interact with treatment or environment in a similar way. For example, genes associated with related biological processes might interact with an environmental factor or a...

Cooperating H3N2 Influenza Virus Variants Are Not Detectable in Primary Clinical Samples.

mSphere

Xue KS, Greninger AL, Pérez-Osorio A, Bloom JD.
PMID: 29299533
mSphere. 2018 Jan 03;3(1). doi: 10.1128/mSphereDirect.00552-17. eCollection 2018.

The high mutation rates of RNA viruses lead to rapid genetic diversification, which can enable cooperative interactions between variants in a viral population. We previously described two distinct variants of H3N2 influenza virus that cooperate in cell culture. These...

Whole-genome sequencing of esophageal adenocarcinoma in Chinese patients reveals distinct mutational signatures and genomic alterations.

Communications biology

Dai JY, Wang X, Buas MF, Zhang C, Ma J, Wei B, Li Y, Zhao B, Hyun TS, Chen X, Loeb KR, Odze R, Yao L, Sun X, Self S, Vaughan TL, Guo Y.
PMID: 30374464
Commun Biol. 2018 Oct 24;1:174. doi: 10.1038/s42003-018-0182-8. eCollection 2018.

While the incidence of esophageal adenocarcinoma (EAC) has risen drastically in Western countries over the last 40 years, a similar trend has not been observed for EAC in China. Here, we analyzed mutational spectrum, copy number alterations, and structural...

Modeling site-specific amino-acid preferences deepens phylogenetic estimates of viral sequence divergence.

Virus evolution

Hilton SK, Bloom JD.
PMID: 30425841
Virus Evol. 2018 Nov 06;4(2):vey033. doi: 10.1093/ve/vey033. eCollection 2018 Jul.

Molecular phylogenetics is often used to estimate the time since the divergence of modern gene sequences. For highly diverged sequences, such phylogenetic techniques sometimes estimate surprisingly recent divergence times. In the case of viruses, independent evidence indicates that the...

Response to Guo et al.'s Letter to the Editor.

Biostatistics (Oxford, England)

Fong Y, Huang Y, Lemos MP, Mcelrath MJ.

Linking influenza virus evolution within and between human hosts.

Virus evolution

Xue KS, Bloom JD.
PMID: 32082616
Virus Evol. 2020 Feb 17;6(1):veaa010. doi: 10.1093/ve/veaa010. eCollection 2020 Jan.

Influenza viruses rapidly diversify within individual human infections. Several recent studies have deep-sequenced clinical influenza infections to identify viral variation within hosts, but it remains unclear how within-host mutations fare at the between-host scale. Here, we compare the genetic...

A comparative study of topology-based pathway enrichment analysis methods.

BMC bioinformatics

Ma J, Shojaie A, Michailidis G.
PMID: 31684881
BMC Bioinformatics. 2019 Nov 04;20(1):546. doi: 10.1186/s12859-019-3146-1.

BACKGROUND: Pathway enrichment extensively used in the analysis of Omics data for gaining biological insights into the functional roles of pre-defined subsets of genes, proteins and metabolites. A large number of methods have been proposed in the literature for...

Doubly robust nonparametric inference on the average treatment effect.

Biometrika

Benkeser D, Carone M, Laan MJV, Gilbert PB.
PMID: 29430041
Biometrika. 2017 Dec;104(4):863-880. doi: 10.1093/biomet/asx053. Epub 2017 Oct 16.

Doubly robust estimators are widely used to draw inference about the average effect of a treatment. Such estimators are consistent for the effect of interest if either one of two nuisance parameters is consistently estimated. However, if flexible, data-adaptive...

On Estimation of the Hazard Function from Population-based Case-Control Studies.

Journal of the American Statistical Association

Hsu L, Gorfine M, Zucker DM.
PMID: 30906082
J Am Stat Assoc. 2018;113(522):560-570. doi: 10.1080/01621459.2017.1356315. Epub 2018 Jun 12.

The population-based case-control study design has been widely used for studying the etiology of chronic diseases. It is well established that the Cox proportional hazards model can be adapted to the case-control study and hazard ratios can be estimated...

phydms: software for phylogenetic analyses informed by deep mutational scanning.

PeerJ

Hilton SK, Doud MB, Bloom JD.
PMID: 28785526
PeerJ. 2017 Jul 31;5:e3657. doi: 10.7717/peerj.3657. eCollection 2017.

It has recently become possible to experimentally measure the effects of all amino-acid point mutations to proteins using deep mutational scanning. These experimental measurements can inform site-specific phylogenetic substitution models of gene evolution in nature. Here we describe software...

Surrogate Endpoint Evaluation: Principal Stratification Criteria and the Prentice Definition.

Journal of causal inference

Gilbert PB, Gabriel EE, Huang Y, Chan IS.
PMID: 26722639
J Causal Inference. 2015 Sep 01;3(2):157-175. doi: 10.1515/jci-2014-0007. Epub 2015 Feb 01.

A common problem of interest within a randomized clinical trial is the evaluation of an inexpensive response endpoint as a valid surrogate endpoint for a clinical endpoint, where a chief purpose of a valid surrogate is to provide a...
