Environmental, developmental, and genetic factors controlling root system architecture [PDF]

open access: yes, 2014
A better understanding of the development and architecture of roots is essential to develop strategies to increase crop yield and optimize agricultural land use.

Functional relevance of the newly evolved sperm dynein intermediate chain multigene family in Drosophila melanogaster males. [PDF]

open access: yes, 2012
In many animal species, traits associated with male fitness evolve rapidly. Intersexual conflict and male-male competition have been suggested to drive this rapid evolution.

Tissue engineering of the gastrointestinal tract: the historic path to translation

open access: yesJournal of Biological Engineering, 2022
The gastrointestinal (GI) tract is imperative for multiple functions including digestion, nutrient absorption, and timely waste disposal. The central feature of the gut is peristalsis, intestinal motility, which facilitates all of its functions ...

Quantitative proteomics and RNA-sequencing of mouse liver endothelial cells identify novel regulators of BMP6 by iron

open access: yesiScience, 2023
Summary: Hepcidin is the master hormone governing systemic iron homeostasis. Iron regulates hepcidin by activating bone morphogenetic protein (BMP)6 expression in liver endothelial cells (LECs), but the mechanisms are incompletely understood.

Postulates on electromagnetic activity in biological systems and cancer [PDF]

open access: yes, 2013
A framework of postulates is formulated to define the existence, nature, and function of a coherent state far from thermodynamic equilibrium in biological systems as an essential condition for the existence of life. This state is excited and sustained by

The Evolution of Student Engagement: Writing Improves Teaching in Introductory Biology [PDF]

open access: yes, 2021
In response to calls for pedagogical reforms in undergraduate biology courses to decrease student attrition rates and increase active learning, this article describes one faculty member’s conversion from traditional teaching methods to more engaging ...

High auxin stimulates callus through SDG8-mediated histone H3K36 methylation in Arabidopsis.

open access: yesJournal of Integrative Plant Biology, 2022
Callus induction, which results in fate transition in plant cells, is considered as the first and key step for plant regeneration. This process can be stimulated in different tissues by a callus-inducing medium (CIM), which contains a high concentration ...

Modeling the Control of TGF-β/Smad Nuclear Accumulation by the Hippo Pathway Effectors, Taz/Yap

open access: yesiScience, 2020
Summary: Integration of transforming growth factor β (TGF-β) signals with those of other pathways allows for precise temporal and spatial control of gene expression patterns that drive development and homeostasis. The Hippo pathway nuclear effectors, Taz/

Effect of macromolecular crowding on the kinetics of glycolytic enzymes and the behaviour of glycolysis in yeast [PDF]

open access: yes, 2018
Water is involved in all aspects of biological activity, both as a solvent and as a reactant. It is hypothesized that intracellular water is in a highly structured state due to the high concentrations of macromolecules in the cell and that this may ...

Morphological landscape of endothelial cell networks reveals a functional role of glutamate receptors in angiogenesis

open access: yesScientific Reports, 2020
Angiogenesis plays a key role in several diseases including cancer, ischemic vascular disease, and Alzheimer’s disease. Chemical genetic screening of endothelial tube formation provides a robust approach for identifying signalling components that impact ...
