The transmembrane protein Neuropilin-1 (NRP1) regulates tumor biology and has been identified as a checkpoint target (ref. 1). High tissue NRP-1 levels are associated with a poor prognosis in breast cancer patients. In a recent study (ref. 2), German researchers have shown that circulating soluble NRP1 serum levels are an independent marker for poor prognosis in early breast cancer. Soluble Neuropilin-1 was quantified in serum with the highly specific NRP1 ELISA from Biomedica.

The secreted extracellular matrix protein Periostin has evolved as a novel therapeutic target and is a robust marker of glioma malignancy and potential tumor recurrence. It has also been implicated in the pathogenesis of breast cancer as high serum levels of periostin are associated with a poor survival in breast cancer patients (ref. 3). Periostin was quantified in serum with the well characterized Biomedica Periostin ELISA that has been published (ref. 4).

Semaphorin 4D (Sema4D) is a glycoprotein that is emerging as clinical biomarker and as therapeutic target in cancer. It has been associated with cancer progression and the occurrence of bone metastases (ref. 5, 6).

Leucine-rich alpha-2-glycoprotein 1 (LRG1) is a protein that is an important factor involved in pathogenic angiogenesis in cancer. It is abundantly present in the microenvironment of many tumors contributing to vascular dysfunction and thus serving as a potential therapeutic target (ref. 7).

The RANKL/RANK/OPG system contributes to the development of bone metastases and influences tumor biology in earlier stages of cancer (ref. 9). Dysregulation has been widely documented in the context of metastatic bone disease (ref. 10). The Biomedica OPG and RANKL ELISA kits have been widely used in the respective studies.
