BACKGROUND
Several epidemiologic studies suggest that higher folate intakes are associated with lower breast cancer risk, particularly in women with moderate alcohol consumption.
OBJECTIVE
We investigated the association between dietary folate, alcohol consumption, and postmenopausal breast cancer

Bioavailability of baicalin (BAI), an example of traditional Chinese medicine, has been modified by loading into liposome. Several liposome systems of different composition i.e., lipid/cholesterol (L), long-circulating stealth liposome (L-PEG) and folate receptor (FR)-targeted liposome (L-FA) have
Modulation of the expression of folate cycle enzymes and polyamine metabolism by berberine in cisplatin-sensitive and -resistant human ovarian cancer cells.

Berberine is a natural isoquinoline alkaloid with significant antitumor activity against many types of cancer cells, including ovarian tumors. This study investigated the molecular mechanisms by which berberine differently affects cell growth of cisplatin (cDDP)-sensitive and -resistant and
In-vitro cytotoxicity and combination effects of the docetaxel-conjugated and doxorubicin-conjugated poly(lactic acid)-poly(ethylene glycol)-folate-based polymeric micelles in human ovarian cancer cells.

OBJECTIVE
The pH-sensitive doxorubicin (DOX)-conjugated and docetaxel (DTX)-conjugated poly(lactic acid)-poly(ethylene glycol)-folate (PLA-PEG-FOL)-based polymeric micelles were developed and characterized in this study.
RESULTS
The drugs were released from the micelles (particle size, ~185 nm) in a
Preparation and performance of a pH-sensitive cisplatin-loaded magnetic nanomedicine that targets tumor cells via folate receptor mediation.

The present study aimed to prepare cisplatin (CDDP)-loaded magnetic nanoparticles (MNPs), which target folate receptors via a pH-sensitive release system (FA‑PEG‑NH‑N=MNPs‑CDDP). This is of interest for the development of intelligent drug delivery systems that target tumors of the head and neck. The
Engineering folate-drug conjugates to target cancer: from chemistry to clinic.

The folate receptor (FR) is a potentially useful biological target for the management of many human cancers. This membrane protein binds extracellular folates with very high affinity and, through an endocytic process, physically delivers them inside the cell for biological consumption. There are now
A new 18F-labeled folic acid derivative with improved properties for the PET imaging of folate receptor-positive tumors.

The folate receptor is a proven target for folate-based diagnosis and treatment of cancer. Several folic acid conjugates have been developed as radiopharmaceuticals, but a suitable (18)F-labeled folic acid derivative for routine clinical use is still lacking. The purpose of this study was to
Decitabine impact on the endocytosis regulator RhoA, the folate carriers RFC1 and FOLR1, and the glucose transporter GLUT4 in human tumors.

BACKGROUND
In 31 solid tumor patients treated with the demethylating agent decitabine, we performed tumor biopsies before and after the first cycle of decitabine and used immunohistochemistry (IHC) to assess whether decitabine increased expression of various membrane transporters. Resistance to
Phase II study of treatment of advanced ovarian cancer with folate-receptor-targeted therapeutic (vintafolide) and companion SPECT-based imaging agent (99mTc-etarfolatide).

BACKGROUND
This report examines 99mTc-etarfolatide imaging to identify the presence of folate receptor (FR) on tumors of women with recurrent/refractory ovarian or endometrial cancer and correlates expression with response to FR-targeted therapySimilar differential for total polyglutamylation and cytotoxicity among various folate analogues in human and murine tumor cells in vitro.

Four folate analogues, methotrexate, aminopterin, 10-deazaminopterin, and 10-ethyl-10-deazaaminopterin were assessed for their ability to be metabolized to poly-gamma-glutamyl derivatives in three tumor lines which vary in their sensitivity to these agents. Cytotoxicity of the four analogues against

Ovarian cancers highly overexpress folate receptor α (FRα) and claudin3 (CLDN3), both of which are associated with tumor progression and poor prognosis of patients. Downregulation of FRα and CLDN3 in ovarian cancer may suppress tumor growth and promote benign differentiation of tumor. In this study,
