Developmental gene regulatory networks in sea urchins and what we can learn from them [version 1; referees: 3 approved]

open access: yesF1000Research, 2016
Sea urchin embryos begin zygotic transcription shortly after the egg is fertilized.  Throughout the cleavage stages a series of transcription factors are activated and, along with signaling through a number of pathways, at least 15 different cell types ...

Protocol for the visualization of pRps6-positive cells in larval zebrafish brains using whole-mount immunofluorescence and light-sheet microscopy

open access: yesSTAR Protocols
Summary: Due to their small size and transparency, larval zebrafish are a useful model for whole-brain imaging. Here, we present a protocol for the visualization of phosphorylated Rps6, a marker of mechanistic target of rapamycin complex 1 (mTORC1 ...

Molecular and cellular mechanisms underlying the evolution of form and function in the amniote jaw. [PDF]

open access: yes, 2019
The amniote jaw complex is a remarkable amalgamation of derivatives from distinct embryonic cell lineages. During development, the cells in these lineages experience concerted movements, migrations, and signaling interactions that take them from their ...

Protocol for microinjection of rapamycin into the zebrafish habenula

open access: yesSTAR Protocols
Summary: Mechanistic target of rapamycin complex 1 (mTorC1) activity plays a crucial role in brain development. Here, we present an approach for rapamycin microinjection into the habenula of larval zebrafish to achieve localized inhibition of the mTorC1 ...

Novel targets of miR-30, a microRNA required for biliary development [v1; ref status: indexed, http://f1000r.es/1so]

open access: yesF1000Research, 2013
MicroRNAs have been found to play a profound role in embryonic and post-natal development through their regulation of processes such as cell proliferation, differentiation, and morphogenesis.

Natural Kinds in Evolution and Systematics: Metaphysical and Epistemological Considerations [PDF]

open access: yes, 2008
Despite the traditional focus on metaphysical issues in discussions of natural kinds in biology, epistemological considerations are at least as important.

Integrated Analysis of Summary Statistics to Identify Pleiotropic Genes and Pathways for the Comorbidity of Schizophrenia and Cardiometabolic Disease

open access: yesFrontiers in Psychiatry, 2020
Genome-wide association studies (GWAS) have identified abundant risk loci associated with schizophrenia (SCZ), cardiometabolic disease (CMD) including body mass index, coronary artery diseases, type 2 diabetes, low- and high-density lipoprotein, total ...

Drosophila as a model system to study nonautonomous mechanisms affecting tumour growth and cell death [PDF]

open access: yes, 2018
The study of cancer has represented a central focus in medical research for over a century. The great complexity and constant evolution of the pathology require the use of multiple research model systems and interdisciplinary approaches.

Computational modeling to elucidate molecular mechanisms of epigenetic memory

open access: yes, 2015
How do mammalian cells that share the same genome exist in notably distinct phenotypes, exhibiting differences in morphology, gene expression patterns, and epigenetic chromatin statuses?
