The future of cell biology as outlined here will increasingly come to rely on systems approaches. This course provides an introduction to cellular and population-level systems biology with an emphasis on synthetic biology, modeling of genetic networks, cell-cell interactions, and evolutionary dynamics.

Accumulated data on the fragmentation properties and chromatographic behavior of peptides has enabled the development of targeted and data-independent proteomics approaches (Farrah et al., 2012). Temporally, they span from very fast processes (e.g., formation of molecular complexes and signaling) to relatively slow processes (e.g., organelle biogenesis and cell division).

An important outcome and aim of systems cell biology will need to be the continued creation and curation of high-quality repositories for systems-level data that ensure accessibility and ease of use for the entire biological community (Hakenberg et al., 2004; Stark et al., 2006; Kowald and Schmeier, 2011; Chatr-aryamontri et al., 2013). 1961;25:585–621. (2011) identified 90 reproducible interactors of GRB2, an important hub in growth factor signaling, and mapped the binding site of each protein to one of three characterized protein binding domains within GRB2. In addition to Crohn’s disease, FOXO3 may also affect the severity of prognosis for other autoimmune diseases including rheumatoid arthritis. Aligning DNA sequences bound to RNA polymerase II pre-initiation complexes and viewing them at a genome scale has provided a unifying view of many regulatory mechanisms governing transcription. Annu.
For example, global monitoring of the GINS complex combined with a very simple model of its movements revealed a surprisingly uniform progression of replication across the genome (Sekedat et al., 2010).
However, it is a misapprehension to think that systems biology is only the acquisition of such large-scale datasets.
Protein–DNA or protein–RNA purification strategies in combination with exonuclease treatment before deep sequencing of the protected fragments provides the ability to map such interactions at a genome-wide scale to within single nucleotide resolution (Ingolia et al., 2009; Rhee and Pugh, 2011). The predictive capacity of the model was subsequently verified in a gene-by-gene focused study of the top candidates to more accurately assess activator or repressor function. The dynamics of GRB2 signaling hub complexes and their association with different receptor tyrosine kinases (RTKs) to form signaling scaffolds were then measured against a battery of different growth factor receptor stimulants (Bisson et al., 2011). The combination of high-content screening and SGA technology has also been used to study peroxisome dynamics (Saleem et al., 2010; Cohen et al., 2014). Importantly, the focus of proteomic studies can move beyond the technicalities of coverage depth or reproducibility, and allows one to pursue interrogation of the kinetic properties of protein complexes.
One striking revelation was the presence of degenerate TATA-like elements at previously characterized “TATA-less” promoters in yeast (Rhee and Pugh, 2012). The result of its application has revealed a wealth of unanticipated complexity in transcript heterogeneity, including novel splice variants, alternative start and stop sites, the lengths of 5′ and 3′ untranslated regions, and the dynamic expression of bicistronic transcripts (Pelechano et al., 2013; Gupta et al., 2014; Pelechano et al., 2014). The constituents of protein complexes measured typically have similar turnover rates, although there are exceptions (for examples see Price et al., 2010). 2003;426(6963):194–198. 2012 Jun;138(6):1045-55. doi: 10.1007/s00432-012-1153-y. Philos.
Recently, alternative operation modalities using certain types of mass spectrometers are making MS-based proteomics studies quantitative and reproducible, with attomole sensitivity (Doerr, 2013; Marx, 2013; Picotti et al., 2013a).

We have active and engaged faculty, students, and researchers who are busy pushing the boundaries of scientific knowledge, bringing science to bear on critical global concerns, gaining attention in national media, and winning major research grants and international honors. Polydispersity is a population phenomenon of proteins owing to their localization to one or more organelles that have nonuniform properties leading, for example, to a collection of different sedimentation coefficients (De Duve et al., 1960; de Duve, 1964). |
The authors declare that they have no competing interests. The unbiased, systematic, and quantitative characterization of genetic interaction networks has inverted the reductionist paradigm in defining a process-centric model of gene function to a component-centric model (Weissman, 2010).

One such promising approach is sequential window acquisition of all theoretical spectra (SWATH-MS), which refers to the way the mass spectrometer is operated to collect these comprehensive proteomics data (Collins et al., 2013). The fate of both coding and noncoding RNA has been mapped by immunoprecipitations of mRNA-binding proteins (Tuck and Tollervey, 2013). Many genes play a role in cellular senescence, yet a comprehensive understanding of its pathways is still lacking. Third, molecular processes of many biological systems inherently occur on multiple scales in time and space. The process is refined by iteration and results in a set of possible structural configurations from which inferences can be made regarding the dynamics of this subcomplex within the much larger nuclear pore complex. One solution to this problem is to systematically infer ontological features from the data itself (Dutkowski et al., 2013). 1). a–e Representative images of fibroblasts following transfection…, NLM In particular, discovering the extent to which different systems mechanisms are responsible for cellular function, and how systems motifs can be combined to bring about new phenotypes, are exciting avenues of pursuit.
