Abstract: Disclosed are compositions and methods to detect proteins associated with Head and Neck Cancer, generally, or more particularly, biomarkers of Head and Neck Squamous Cell Carcinoma (HNSCC). Such markers may be useful to allow individuals susceptible to HNSCC to manage their lifestyle and/or medical treatment to avoid further progression of disease.

Abstract: Provided are methods of detecting and quantitatively measuring protein-protein interactions between proteins present on the surface of different cells using a sensitive antibody-based assay. Antibodies specific for each target protein are either directly labeled, or are detected by labeled secondary antibodies. The antibodies are labeled with detectable tags that are releasable when the target proteins are within proximity to each other. Also provided are methods for facilitating diagnosis, prognosis, and treatment of cancer using this assay to detect protein-protein interactions between target proteins of interest. Methods of screening test agents that impact the protein-protein interaction are also provided.

Abstract: Compositions, kits, and methods are disclosed for determining one or more target polypeptides in a sample where the target polypeptides have undergone a post-translational modification. The compositions can include a first reagent including a cleavage-inducing moiety and a first binding agent for a binding site that includes a post-translational modification of a target polypeptide.

Abstract: Methods, compositions and kits are disclosed for determining one or more target polypeptides in a sample where the target polypeptides have undergone a post-translational modification. A mixture comprising the sample and a first reagent comprising a cleavage-inducing moiety and a first binding agent for a binding site on a target polypeptide is subjected to conditions under which binding of respective binding moieties occurs. The binding site is the result of post-translational modification activity involving the target polypeptide. The method may be employed to determine the target polypeptide itself. In another embodiment the presence and/or amount of the target polypeptide is related to the presence and/or amount and/or activity of an agent such as an enzyme involved in the post-translational modification of the target polypeptide.

Abstract: Systems and methods are provided for facilitating diagnosis, prognosis and treatment of cancer based on detection of HER3 activation. The systems and methods involve analysis of samples for the presence or the absence of activated HER3 markers as indicated by HER2-HER3 heterodimers, HER3 phosphorylation, or recruitment of PI3K to activated HER3 (HER3/PI3K complexes). The amounts of activated HER3 marker expression may be measured alone or in conjunction with other biomarkers.

Abstract: The invention provides methods of measuring and/or quantifying the presence and/or amount of p95 and/or p95 complex in a sample. The invention also provides antibodies specific for p95, and methods of making such antibodies.

Abstract: Methods are provided for facilitating the diagnosis of subjects with HER1-activated cancers. In addition, method of treating subjects with a cancer characterized as having high levels of activated HER1 are provided. Also provided are methods for determining or otherwise assessing the prognosis of an subject with a HER1-activated cancer. The methods include the analysis of samples for the presence or the absence of activated HER1 markers as indicated by HER1-HER1 homodimers, HER1 phosphorylation at position 1173, pan-phosphorylation of HER1 or associated molecules, or HER1-HER2 heterodimers. Activated HER1 measurements can be used to track a subject's response to a treatment regimen, predict the success of using a particular treatment regimen, determine the effects of a treatment regimen, or for categorizing a subject in order to create a homogenous group for a clinical trial.
