Ethylene signalling is involved in regulation of phosphate starvation-induced gene expression and production of acid phosphatases and anthocyanin in Arabidopsis.

New Phytologist, 2011
• With the exception of root hair development, the role of the phytohormone ethylene is not clear in other aspects of plant responses to inorganic phosphate (Pi) starvation.

Circulating tumor cells in metastatic breast cancer patients treated with immune checkpoint inhibitors – a biomarker analysis of the ALICE and ICON trials

Molecular Oncology, EarlyView.
In this explorative biomarker analysis, we assessed serial sampling of circulating tumor cells (CTCs) with CellSearch in two randomized trials testing immune checkpoint inhibitors (ICIs) in metastatic breast cancer. Our data demonstrate a prognostic potential of CTCs, most apparent 4 weeks into ICI therapy.

Enhanced AGAMOUS expression in the centre of the Arabidopsis flower causes ectopic expression over its outer expression boundaries [PDF]

, 2009
Spatial regulation of C-function genes controlling reproductive organ identity in the centre of the flower can be achieved by adjusting the level of their expression within the genuine central expression domain in Antirrhinum and Petunia.

Imprinting in plants as a mechanism to generate seed phenotypic diversity

Frontiers in Plant Science, 2015
Normal plant development requires epigenetic regulation to enforce changes in developmental fate. Genomic imprinting is a type of epigenetic regulation in which identical alleles of genes are expressed in a parent-of-origin dependent manner.

Plant defense multigene families: I. Divergence of Fusarium solani-induced expression in Pisum and Lathyrus [PDF]

arXiv, 2003
The defense response in plants challenged with pathogens is characterized by the activation of a diverse set of genes. Many of the same genes are induced in the defense responses of a wide range of plant species. How plant defense gene families evolve may therefore provide an important clue to our understanding of how disease resistance evolves ...

A dynamical system model for predicting gene expression from the epigenome [PDF]

arXiv, 2020
Gene regulation is an important fundamental biological process. The regulation of gene expression is managed through a variety of methods including epigenetic processes (e.g., DNA methylation). Understanding the role of epigenetic changes in gene expression is a fundamental question of molecular biology.

L-leucine, L-methionine, and L-lysine are involved in the regulation of intermediary metabolism-related gene expression in rainbow trout hepatocytes.

Journal of NutriLife, 2011
Using rainbow trout hepatocytes stimulated with l-leucine, l-methionine, or l-lysine in the presence or absence of bovine insulin, we investigated the ability of these amino acids to mimic the effects of a pool of amino acids on protein kinase B (Akt ...

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

Molecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

A Role of Cytokinin Transporter in Arabidopsis Immunity

Molecular Plant-Microbe Interactions, 2017
The phytohormone cytokinin (CK) is not only essential for plant growth and development but also impacts plant immunity. A mutant screen in a constitutively active plant immune receptor mutant snc1 (suppressor of npr1, constitutive1) identified a ...

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.
