Dr. Mohammad Mofatteh graduated with a First-Class Honours degree in Biomedical Sciences from King’s College London in 2014. Subsequently, he accepted a prestigious PhD Scholarship from the University of Cambridge to conduct his doctorate research at the MRC-Laboratory of Molecular Biology. As a passionate lifelong learner, Dr. Mofatteh has also studied for a Master of Public Health (MPH) from the University of Sheffield, and a Master of Science (MSc) in Psychology from the University of Liverpool. Currently, Dr. Mofatteh is a BTG Junior Research Fellow in Biomedical Sciences at Lincoln College and Sir William Dunn School of Pathology at the University of Oxford in England. Dr. Mofatteh has used cutting-edge microscopy, genetics, cellular and biochemical techniques to investigate the mechanism of mRNA trafficking, post-transcriptional modifications, and local translation in neurons. Neurons establish intricate connections with other neurons and tissues to receive, process, and send vital information for survival of animals. The previous dominant belief in biology was that mRNAs were boring molecular copies to bridge the gap between the double helix of life, i.e. DNA, and the microscopic catalysts of life, i.e. proteins. With the advancements in pioneering imaging, sequencing, in vivo and in vitro cellular and biochemical techniques, he and his team have recently unraveled that mRNAs are not just simple messenger molecules; they are dynamic molecules with crucial roles in the life cycle of a neuron. mRNAs can be transported, modified, recycled, and translated under internal and external control. He is of the opinion that ‘Transcription is not just the end of the story, but the beginning of a new beginning!’

Collection Overview

Highly polarized cells such as neurons have various compartments and require to rapidly respond to internal and external stimuli by altering the abundance and constitution of proteins. Neurons particularly rely on extensive spatial and temporal regulations of gene expression to receive, process, and restore information by creating functional and structural neuronal networks. Both developing and mature neurons can achieve this by using an evolutionarily conserved mechanism: trafficking-specific mRNAs to dendritic and axonal extensions, followed by localized protein synthesis. mRNA localization coupled to local translation is present in different stages of a neurons’ lifecycle, such as during axon guidance, synaptic formation and plasticity, neuronal injury, and degeneration.

The structural and functional complexity of the nervous system poses a challenge in studying mRNA localization and local translation. To this end, a repertoire of multidisciplinary in vivo and in vitro techniques in both single cell and tissue levels have been developed to shed lights on the mechanism by which transcripts are transported and translated. This Methods Collection aims to provide a platform to share and distribute cutting edge and novel ideas and protocols in a wide variety of in vivo and in vitro topics in the field including but not limited to preparation and handling of neurons and tissues, RNA and protein isolation, library preparation, single-molecule, cell and total labelling, live and fixed-tissue imaging of RNAs and proteins, transcriptomic, proteomic, gene expression and inhibition, in vitro reconstitution, image analysis, processing and quantification.
