Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Nitrogen forms affect root structure and water uptake in the hybrid poplar [PDF]

, 2011
The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field experiment.

Root Pruning and Auxin Alter Root Morphology of Hickories [PDF]

HortScience, 2019
A reputation for coarse root systems with dominant taproots, and for slow shoot development among seedlings, limits use of hickory species ( Carya Nutt.) that could increase diversity in managed landscapes.

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 ...

Root canal morphology of mandibular premolars

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2004
Background and Objective: Missed canals are one of the main reasons of root canal treatment failure of mandibular premolars. The dentist must have a thorough knowledge of the morphology of the root canal before he/she can successfully treat a tooth ...

The variation in the number of roots and canals morphology of permanent mandibular first molar teeth by using cone beam computed tomography imaging in a sample of Erbil city

Erbil Dental Journal, 2020
Background and Objectives: Adequate knowledge about the number of roots, canals, and morphology of lower first molar teeth is a basic requirement of root canal therapy and any surgical treatment in this region, was carried out to investigate root and ...

Short wind pulses consistently change the morphology of roots, but not of shoots, across young plants of different growth forms

Stress Biology, 2023
Wind is an environmental stimulus that stresses plants of all growth forms at all life-stages by influencing the development, architecture, and morphology of roots and shoots.

Segmentation of root and pattern morphology

, 2021
Morphology is the study of how form and meaning are combined to form complex words. While previous studies of morphology learning rely on semantic associations of continuous affixes (e.g., prefixes and suffixes), the present study focuses on the learnability of non-continuous (non-concatenative) forms, without the use of semantic information.

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 ...
