Examples for such markers/targets, in the case of breast cancer, are the oestrogen receptor (ER), progesterone receptor (PgR), and the Erb2/Her2 molecule, a receptor tyrosine protein kinase that is overexpressed in a subset of breast cancers. There are number of treatment options for tumours that express the ER, PgR or Her2 receptors, however up to 20 percent of the newly diagnosed cases belong to a subset, which is negative for all three of the receptor molecules. This presentation will discuss applications of high-resolution hybrid mass spectrometry for quantitative genome-scale studies of protein abundance and post-translational modifications. The current state-of-the-art technology for large-scale proteome analysis of individual solid tumours is discussed. Case studies from experiments with triple-negative breast and colorectal tumours illustrating the capability of the proteome-based strategies are presented, as well as mechanistic investigations in cultured cells that have been informed by tumour proteomics and focus on specific phosphorylation hotspots and protein interactions of the tumour suppressor Scribble.
Genome-Scale Protein Expression Analysis of Individual Solid Tumors

Northwestern University and Washington University School of Medicine researchers have developed the first example of a bioelectronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves healing of a damaged nerve. Their device delivered pulses of electricity to damaged nerves in rats after a surgical repair process, accelerating the regrowth of nerves and enhancing the recovery of muscle strength and control. The device is the size of a dime and the thickness of a sheet of paper and dissolves in the body after about two weeks.
