چکیده انگلیسی


- The FSHP modified nanoparticle drug delivery system was assessed in treating lymphatic metastasis of ovarian cancer first time.
- The PTX concentration in the lymph nodes in the FSHP-NP-PTX group was higher than that in the other groups.
- FSHP-NP-PTX exhibits the most significant inhibiting effect on cell proliferation both in vitro and in vivo.

ObjectiveTraditional chemotherapy drugs have an obvious drawback of nonspecific biodistribution in treating ovarian cancer. Follicle-stimulating hormone receptor (FSHR), a G-protein coupled receptor which is mainly expressed in reproductive system, is an important drug target in developing novel therapeutics.MethodsUsing a polypeptide of follicle-stimulating hormone (named as FSHP), a conjugated nanoparticle, FSHP-NP was developed to target FSHR in lymphatic metastasis of ovarian cancer. FSHP-NP was tested for recognition specificity and uptake efficiency on FSHR-expressing cells. A paclitaxel (PTX)-loaded FSHP-NP (FSHP-NP-PTX) was further developed and its anti-tumor effect was determined in vivo and in vitro.ResultsTaking NuTu-19 cells as an example, FSHP-NP-PTX displayed significantly stronger anti-cell proliferative and anti-tumor effects in a dose- and time-dependent manner when compared with free PTX or naked PTX-loaded nanoparticles (NP-PTX) in vitro. In vivo examinations showed that the size and weight of the lymph nodes were reduced in the FSHP-NP-PTX group.ConclusionFSHR as a novel therapeutic target in ovarian cancer and delivery of PTX via conjugated nanoparticle (FSHP-NP) might represent a new therapeutic approach in ovarian cancer.
