Large genetic screens in model organisms have led to the identification of negative genetic interactions. Here, we describe a data integration workflow using data from genetic screens in model organisms to delineate drug combinations targeting synthetic lethal interactions in...

This video presents synthetic biology and its role in bioengineering. Synthetic biology refers to the methods used to genetically modify organisms in order to make them capable of producing large quantities of a product. This product could be a protein that the cell already makes or a new protein that has been encoded in a newly-inserted DNA sequence.
Here, we discuss how an organism's genetic material is modified using transformation or transfection. Then, the process is shown in the...

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

The video demonstrates an assay to identify target-selective neurons via simultaneous eye-tracking and single-neuron recordings. A human participant is tasked with identifying a target object among an array of objects in a display, and the eye movement is tracked. Simultaneously, single neurons' firing rate is recorded via electrodes implanted in the brain. The data from both recordings are correlated to assess the presence of target-selective...

The goal of the protocol is to provide a method for producing non-invasive neuronal lesions in the brain. The method utilizes Magnetic Resonance-guided Focused Ultrasound (MRgFUS) to open the Blood Brain Barrier in a transient and focal manner, in order to deliver a circulating neurotoxin to the brain...

(2018) In this video, a two-photon laser ablation procedure is demonstrated, enabling the selective destruction of fluorescent neurons in agarose-immobilized zebrafish larvae. High-resolution imaging before and after the procedure confirms efficient neuronal damage, as observed by the absence...
