A major focus of breast cancer research is to understand the mechanisms responsible for disease progression and drug resistance. Toward that end, it has been found that approximately two thirds of all human breast carcinomas overexpress the Estrogen Receptor α (ERα) protein and it remains the primary pharmacological target for endocrine therapy1,2. The normal cellular function of ERα is as a transcription factor that mediates a wide variety of physiological processes, many of which are dependent upon phosphorylation of the receptor at specific amino acid residues3,4. Indeed, ERα is known to be phosphorylated at a multitude of different sites, yet how these all correlate to disease remains unclear5. Here, we interrogated multiple sites of ERα for phosphorylation status by screening an extensive panel of different breast cancer patient samples and other non-breast cancer tissue microarray (TMA) slide samples to determine their relevance to disease.

Alzheimer’s Disease is a progressively deteriorating disease. It manifests itself with memory loss, confusion, problems with judgment, planning, concentration, and personality changes; and in it’s later stages, a decline in physical abilities. The disease’s causes, cures, and preventions are unknown; however, key proteins likely involved in the degenerative mechanism have been identified. Alzheimer’s Disease is characterized by neuronal loss, alterations in neurotransmitter systems, and the presence of neurofibrillary tangles composed of abnormally hyperphosphorylated tau proteins. A prominent feature of Alzheimer’s Disease is the formation of senile plaques in selected regions of the brain. The center of these plaques are composed mainly of fibrillary aggregates of a common, but not well understood, b amyloid peptides (Aβ). The Aβ peptides are generated from the larger amyloid-β precursor protein (APP) by the sequential action of β- and γ-secretase, and it is generally accepted that oligomeric forms of this Aβ are neurotoxic, resulting in disease progression.
