Abstract Living cells are hugely complex chemical systems composed of a milieu of distinct chemical species including DNA, proteins, lipids, and metabolites interconnected with one another through a vast web of interactions: this complexity renders the study of cell biology in a quantitative and systematic manner a difficult task.
Impact statement Recent years have seen an increasing drive to construct cell mimics and use them as simplified experimental models to replicate and understand biological phenomena in a well-defined and controlled system. Keywords: Artificial cells, biomimetics, synthetic biology, biophysics. Introduction The construction of artificial cells that resemble biological cells in form and function is a rapidly growing area of research. Open in a separate window.
Figure 1. Figure 2. Cell membrane mimics Historically, the plasma membrane has been the most well-developed cellular component to be mimicked and used as a model. Investigating cellular structural components Artificial cell models are increasingly used in investigations relating to the mechanisms of action of various structural components and associated machineries. Figure 3. Figure 4. Macromolecular crowding It has long been known that protein folding, stability, and function, as well as enzymatic reaction kinetics and mechanisms, are influenced by molecular crowding through reduced diffusion times and increased molecular binding rates.
Cells-on-chip Construction of artificial cells for fundamental biology need not be limited to membrane-encapsulated systems. Perspectives and conclusions The synopsis above shows that cell mimics have been used for a range of studies in fundamental biological research, and towards the construction of functional artificial cells.

Indeed, ribosome biogenesis has been studied almost exclusively using genetic and biochemical approaches without the benefit of small-molecule inhibitors of this process. Here, we provide a perspective on the promise of chemical inhibitors of ribosome assembly for future research. We explore key obstacles that complicate the interpretation of studies aimed at perturbing ribosome biogenesis in vivo using genetic methods, and we argue that chemical inhibitors are especially powerful because they can be used to induce perturbations in a manner that obviates these difficulties.
Thus, in combination with leading-edge biochemical and structural methods, chemical probes offer unique advantages toward elucidating the molecular events that define the assembly of ribosomes.

Proper gene expression is essential for the survival of every cell. Once thought to be a passive transporter of genetic information, RNA has recently emerged as a key player in nearly every pathway in the cell.
A full description of its structure is critical to understanding RNA function. Decades of research have focused on utilizing chemical tools to interrogate the structures of RNAs, with recent focus shifting to performing experiments inside living cells. This Review will detail the design and utility of chemical reagents used in RNA structure probing. We also outline how these reagents have been used to gain a deeper understanding of RNA structure in vivo. We review the recent merger of chemical probing with deep sequencing.
Finally, we outline some of the hurdles that remain in fully characterizing the structure of RNA inside living cells, and how chemical biology can uniquely tackle such challenges. The upswing in US Food and Drug Administration and European Medicines Agency drug approvals in may have marked an end to the dry spell that has troubled the pharmaceutical industry over the past decade. Regardless, the attrition rate of drugs in late clinical phases remains high, and a lack of target validation has been highlighted as an explanation.
This has led to a resurgence in appreciation of phenotypic drug screens, as these may be more likely to yield compounds with relevant modes of action. However, cell-based screening approaches do not directly reveal cellular targets, and hence target deconvolution and a detailed understanding of drug action are needed for efficient lead optimization and biomarker development. Here, recently developed functional genomics technologies that address this need are reviewed.
The approaches pioneered in model organisms, particularly in yeast, and more recently adapted to mammalian systems are discussed.
Finally, areas of particular interest and directions for future tool development are highlighted. My account Submit manuscript Register Subscribe.
