Folate receptors are a family of cell surface receptors that bind the essential vitamin folic acid (folate, vitamin B9). These receptors are upregulated in highly metabolic cells and over-expression of FRA protein is associated with tumor growth, as uptake of folic acid is a necessary part of tumor metabolism.

Folate is essential for cellular metabolism and DNA synthesis, methylation, and repair. High metabolic cells such as proliferating cancer cells have increased demand for folate to maintain their accelerated DNA synthesis; thus overexpression of folate receptors (FRs) is a recognized biomarker of many tumors, though tumors can differ in their dependence on folate metabolism.

Quantitative assessment of folate receptor expression by FMT imaging with a NIR fluorescent folate agent

Folic acid (vitamin B9) is an essential nutrient required by eukaryotic cells for survival that is acquired and internalized via folate receptors (FR) on the cell surface. In particular, it is the highly metabolic cells that upregulate FR, and many different human tumor cells, including ovarian, breast, cervical, renal, colorectal and nasopharyngeal cancer cells show significant upregulation as compared to normal tissues. As such, folic acid has been successfully exploited as a cancer specific targeting moiety for the efficient delivery of chemotherapeutic agents, drug carriers, photosensitizers and diagnostic reporters. Critical to the success of such agents is the determination of the level of FR expression for a given tumor, since weak FR-expressing cancers will not respond well to folate-targeted therapies. There is therefore a need for specific and quantitative imaging agents

White Paper

The Role of In Vivo Imaging in Drug Discovery and Development

The primary goal of preclinical imaging is to improve the odds of clinical success and reduce drug discovery and development time and costs. Advances in non-invasive in vivo imaging techniques have raised the use of animal models in drug discovery and development to a new level by enabling quick and efficient drug screening and evaluation. Read this White Paper to learn how preclinical in vivo imaging helps to ensure that smart choices are made by providing Go/No-Go decisions and de-risking drug candidates early on, significantly reducing time to the clinic and lowering costs all while maximizing biological understanding.
