In the present invention, the use of the TAS1R3 receptor as a biomarker for application in cancer diagnosis, monitoring, and therapy is described for the first time. In this sense, the authors of the present invention have demonstrated that TAS1R3 is a biomarker of interest in oncology, useful for the diagnosis of the disease, and capable of providing relevant information thereupon, to monitor the evolution, select the treatment, and selectively direct therapeutic molecules. It has been determined that it is possible to identify therapies against this receptor, and that it is also possible to direct conjugates and controlled release systems of drugs, such as nanoparticles, observing a very effective intracellular accumulation thereof in primary, disseminated and metastatic tumor cells. On the other hand, the presence of TAS1R3 in circulating tumor cells (CTCs) has also been demonstrated. These are tumor cells released into the bloodstream by the primary tumor and are considered key factors ...

This invention describes of a means of stabilizing lipophilic drugs for long-term storage by incorporating them into a “thermally stabilized nanoemulsion” that has a phase transition temperature that is at or below the body temperature of 37 C and above a storage temperature of 4-8 C. One or more lipid soluble drugs are incorporated into the nanoemulsion at an elevated temperature above the phase transition temperature of the nanoemulsion and then stabilized for extended storage by lowering the temperature to below its phase transition temperature. This causes the nanoemulsion to transform into solid lipid nanospheres entrapping the drug within the solid lipid matrix. Upon rewarming the lipid nanospheres they will reconvert to an oil-in-water nanoemulsion suitable for administration to the patient in need. This invention further discloses disease targeting thermally stabilized nanoemulsions utilizing targeting agents such as antibodies, aptamers, binding peptides, hormones, cytokines and the like, attached to the exterior of the nanodroplets comprising the nanoemulsion. 1.

Use of the tas1r3 protein as a marker for therapeutic, diagnostic, and/or prognostic purposes for tumors that express said protein

Номер: US20210275680A1

In the present invention, the use of the TAS1R3 receptor as a biomarker for application in cancer diagnosis, monitoring, and therapy is described for the first time. In this sense, the authors of the present invention have demonstrated that TAS1R3 is a biomarker of interest in oncology, useful for the diagnosis of the disease, and capable of providing relevant information thereupon, to monitor the evolution, select the treatment, and selectively direct therapeutic molecules. It has been determined that it is possible to identify therapies against this receptor, and that it is also possible to direct conjugates and controlled release systems of drugs, such as nanoparticles, observing a very effective intracellular accumulation thereof in primary, disseminated and metastatic tumor cells. On the other hand, the presence of TAS1R3 in circulating tumor cells (CTCs) has also been demonstrated. These are tumor cells released into the bloodstream by the primary tumor and are considered key factors in the creation of metastases, so that their detection in early stages will serve as an early detector of metastasis, and are also useful in monitoring the disease and evaluating of the response to drugs.

The nanoparticles are coated with an anti-Vascular Endothelial Growth Factor Receptor (VEGFR) targeting agent such as anti-VEGFR antibodies, anti-VEGFR aptamers, anti-VEGFR binding peptides and the like. Upon administration into the eye of a patient with ARMD the targeting agent on the nanoparticle will bind to VEGFR on neovascular cells in the retina and inhibit the abnormal proliferation of new blood vessels. In addition to its therapeutic action the targeting agent by binding to its receptor will anchor the drug delivery vehicle at the site of inflammation where the anti-inflammatory drug is released for maximum effect in inhibiting the local inflammatory response.
