A data-driven statistical model that estimates measurement uncertainty improves interpretation of ADC reproducibility: a multi-site study of liver metastases.
(NATURE PORTFOLIO, 2017-10-26)
Apparent Diffusion Coefficient (ADC) is a potential quantitative imaging biomarker for tumour cell density and is widely used to detect early treatment changes in cancer therapy. We propose a strategy to improve confidence ...
Biopsy variability of lymphocytic infiltration in breast cancer subtypes and the ImmunoSkew score.
(NATURE PORTFOLIO, 2016-11-04)
The number of tumour biopsies required for a good representation of tumours has been controversial. An important factor to consider is intra-tumour heterogeneity, which can vary among cancer types and subtypes. Immune cells ...
Correlation of Ultrasound Shear Wave Elastography with Pathological Analysis in a Xenografic Tumour Model.
(NATURE PORTFOLIO, 2017-03-13)
The objective of this study was to evaluate the potential value of ultrasound (US) shear wave elastography (SWE) in assessing the relative change in elastic modulus in colorectal adenocarcinoma xenograft models in vivo and ...
AMPK-independent inhibition of human macrophage ER stress response by AICAR.
(NATURE PORTFOLIO, 2016-08-26)
Obesity-associated insulin resistance is driven by inflammatory processes in response to metabolic overload. Obesity-associated inflammation can be recapitulated in cell culture by exposing macrophages to saturated fatty ...
Signatures of positive selection reveal a universal role of chromatin modifiers as cancer driver genes.
(NATURE PORTFOLIO, 2017-10-13)
Tumors are composed of an evolving population of cells subjected to tissue-specific selection, which fuels tumor heterogeneity and ultimately complicates cancer driver gene identification. Here, we integrate cancer cell ...
A Novel Statistical Method to Diagnose, Quantify and Correct Batch Effects in Genomic Studies.
(NATURE PORTFOLIO, 2017-09-07)
Genome projects now generate large-scale data often produced at various time points by different laboratories using multiple platforms. This increases the potential for batch effects. Currently there are several batch ...
A non-cell autonomous mouse model of CNS haemangioblastoma mediated by mutant KRAS.
(NATURE PORTFOLIO, 2017-03-21)
Haemangioblastoma is a rare malignancy of the CNS where vascular proliferation causes lesions due to endothelial propagation. We found that conditionally expressing mutant Kras, using Rag1-Cre, gave rise to CNS haemangioblastoma ...
The evolutionary landscape of colorectal tumorigenesis.
(NATURE PORTFOLIO, 2018-10-01)
The evolutionary events that cause colorectal adenomas (benign) to progress to carcinomas (malignant) remain largely undetermined. Using multi-region genome and exome sequencing of 24 benign and malignant colorectal tumours, ...
Robust RNA-based in situ mutation detection delineates colorectal cancer subclonal evolution.
(NATURE PUBLISHING GROUP, 2017-12-08)
Intra-tumor heterogeneity (ITH) is a major underlying cause of therapy resistance and disease recurrence, and is a read-out of tumor growth. Current genetic ITH analysis methods do not preserve spatial context and may not ...
Crypt fusion as a homeostatic mechanism in the human colon.
(BMJ PUBLISHING GROUP, 2019-11-01)
OBJECTIVE: The crypt population in the human intestine is dynamic: crypts can divide to produce two new daughter crypts through a process termed crypt fission, but whether this is balanced by a second process to remove ...
