Here, we aimed to develop novel biodegradable poly(DL-lactide--glycolic acid) phase-transition nanoparticles simultaneously loaded with oxygen and indocyanine green (OI-NPs) and to investigate the cytotoxic effects and the potential mechanisms of OI-NP-mediated PSDT on MH7A synoviocytes.

Ultrasound-mediated destruction of oxygen and paclitaxel loaded dual-targeting microbubbles for intraperitoneal treatment of ovarian cancer xenografts.

Folate receptor (FR) is overexpressed in many epithelial cancers and tumor-associated macrophages (TAMs), which enable it to function as an appropriate target for cancer treatment. We have successfully synthesized multifunctional folate-targeted and oxygen/paclitaxel loaded microbubbles (TOPLMBs) for ultrasound (US) mediated delivery for combination therapy in an intraperitoneal ovarian cancer xenograft model. The TOPLMBs target both ovarian cancer cells and TAMs and provide a promising drug delivery strategy for the combination treatment of ovarian cancer and tumor microenvironment.

Ultrasound-mediated destruction of LHRHa-targeted and paclitaxel-loaded lipid microbubbles induces proliferation inhibition and apoptosis in ovarian cancer cells.

Although paclitaxel (PTX) is used with platinum as the first line chemotherapy regimen for ovarian cancer, its clinical efficacy is often limited by severe adverse effects. Ultrasound-targeted microbubble destruction (UTMD) technique holds a great promise in minimizing the side effects and maximizing the therapeutic efficacy. However, the technique typically uses nontargeted microbubbles with suboptimal efficiency.

Ultrasound-mediated destruction of LHRHa-targeted and paclitaxel-loaded lipid microbubbles for the treatment of intraperitoneal ovarian cancer xenografts.

Ultrasound-targeted microbubble destruction (UTMD) is a promising technique to facilitate the delivery of chemotherapy in cancer treatment. However, the process typically uses nonspecific microbubbles, leading to low tumor-to-normal tissue uptake ratio and adverse side effects. In this study, we synthesized the LHRH receptor-targeted and paclitaxel (PTX)-loaded lipid microbubbles (TPLMBs) for tumor-specific binding and enhanced therapeutic effect at the tumor site.

The women in the treatment group received daily low-intensity ultrasound treatment for 30 min 24 h after the delivery for 3 consecutive days, and the control group had no particular treatments.

Energy controllable steep pulse (ECSP) treatment suppresses tumor growth in rats implanted with Walker 256 carcinosarcoma cells through apoptosis and an antitumor immune response.

Electrochemotherapy has been widely used for the treatment of solid tumors, although the underlying mechanism remains unclear. We aimed to investigate the effects of energy controllable steep pulse (ECSP) on the regulation of tumor growth and apoptosis in rats implanted with Walker 256 carcinosarcoma cells. A rat tumor model was established by injection of Walker 256 carcinosarcoma cells into the inguinal area.

Targeted microbubbles for ultrasound mediated gene transfection and apoptosis induction in ovarian cancer cells.

Ultrasound-targeted microbubble destruction (UTMD) technique can be potentially used for non-viral delivery of gene therapy.
