RHAMM (CD168) Is Overexpressed at the Protein Level and May Constitute an Immunogenic Antigen in Advanced Prostate Cancer Disease

Prostate stem cell antigen is overexpressed in prostate cancer metastases.

PURPOSE Prostate stem cell antigen (PSCA) is expressed by a majority of prostate cancers and is a promising therapeutic target. PSCA protein and mRNA expression was examined in prostate cancer bone, lymph node, and visceral metastases to assess the potential of PSCA as an immunotherapeutic target in advanced prostate cancer. EXPERIMENTAL DESIGN Immunohistochemical analysis of PSCA protein exp...

RHAMM/HMMR (CD168) is not an ideal target antigen for immunotherapy of acute myeloid leukemia.

BACKGROUND Criteria for good candidate antigens for immunotherapy of acute myeloid leukemia are high expression on leukemic stem cells in the majority of patients with acute myeloid leukemia and low or no expression in vital tissues. It was shown in vaccination trials that Receptor for Hyaluronic Acid Mediated Motility (RHAMM/HMMR) generates cellular immune responses in patients with acute myel...

What is the most appropriate test in detecting prostate cancer in patients with intermediate prostate specific antigen levels?

  Abstract   Background: Regarding the variety of tests present for detecting and also screening   prostate cancer and also bearing in mind the advantages and disadvantages of   these tests we decided to re-evaluate these tests (total prostate specific antigen and all   of its modifications) in detecting prostate cancer in men with intermediate serum   PSAlevels.   Methods: Following a cross se...

Prostate Derived Ets Factor, an Immunogenic Breast Cancer Antigen

The tumor-associated antigen RHAMM (HMMR/CD168) is expressed by monocyte-derived dendritic cells and presented to T cells

We formerly demonstrated that vaccination with Wilms' tumor 1 (WT1)-loaded autologous monocyte-derived dendritic cells (mo-DCs) can be a well-tolerated effective treatment in acute myeloid leukemia (AML) patients. Here, we investigated whether we could introduce the receptor for hyaluronic acid-mediated motility (RHAMM/HMMR/CD168), another clinically relevant tumor-associated antigen, into thes...
