Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Rotation-invariance is essential for accurate detection of spatially variable genes in spatial transcriptomics

Nature Communications
In spatial transcriptomics, tissue samples are randomly positioned. Rotation-sensitive methods can lead to unreliable spatially variable gene (SVG) detection.

Lack of Effect of H2-Receptor Antagonists and Antacids on the Gastric and Duodenal Gastrin-, Somatostatin- and Serotonin-Producing Cells in Patients with Acid Peptic Disorders

Canadian Journal of Gastroenterology, 1996
Standard therapeutic approaches to acid peptic disorders have dealt with neutralizing or inhibiting aggressive factors and/or bolstering defensive factors.

Record statistics in random vectors and quantum chaos

, 2013
The record statistics of complex random states are analytically calculated, and shown that the probability of a record intensity is a Bernoulli process.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

STANCE: a unified statistical model to detect cell-type-specific spatially variable genes in spatial transcriptomics

Nature Communications
One of the major challenges in spatial transcriptomics is to detect spatially variable genes (SVGs), whose expression patterns are non-random across tissue locations.

Positive Correlation between Normal Serum Gastrin Concentrations and Antral and Duodenal G Cells

Canadian Journal of Gastroenterology, 1994
It is controversial whether there is a correlation between serum gastrin concentrations and the density of G cells in the antral or duodenal mucosa. In this study, endoscopically obtained antral and duodenal biopsies were stained immunocytochemically for

Investigation of sample paths properties for some classes of φ-sub-Gaussian stochastic processes

Modern Stochastics: Theory and Applications, 2021
This paper investigates sample paths properties of φ-sub-Gaussian processes by means of entropy methods. Basing on a particular entropy integral, we treat the questions on continuity and the rate of growth of sample paths.
