Abstract: Increasing the clinical efficacy of toxic chemotherapy drugs such as cisplatin (CDDP), via targeted drug delivery, is a key area research in cancer treatment. In this study, CDDP-loaded poly(lactic-co-glycolic acid) (PLGA) polymeric nanoparticles (NPs) were successfully prepared using electrohydrodynamic atomization (EHDA). The configuration was varied to control distribution CDDP within particles, and high encapsulation efficiency (>70%) achieved. NPs produced with either...

The transcription factor Nrf2 is a key regulator of the cellular antioxidant response, and its activation by chemoprotective agents has been proposed as potential strategy to prevent cancer. However, activating mutations in pathway have found promote tumorigenesis certain models. Therefore, role cancer remains contentious.We employed well-characterized model stepwise human mesenchymal stem cell (MSC) transformation breast lines investigate oxidative stress during tumorigenesis. was studied...

Background Research using orthotopic and transgenic models of cancer requires imaging methods to non-invasively quantify tumour burden. As the choice appropriate modality is wide-ranging, this study aimed compare low-field (1T) magnetic resonance (MRI), a novel relatively low-cost system, against established preclinical techniques: bioluminescence (BLI), ultrasound (US), high-field (9.4T) MRI. Methods A model colorectal metastasis liver was in eight mice, which were imaged with each over...

Induction of apoptosis is often necessary for successful cancer therapy, and the non-invasive monitoring post-therapy could assist in clinical decision making. Isatins are a class compounds that target activated caspase-3 during apoptosis.

Intra-arterial Lipiodol has been used to deliver targeted therapies primary, and some metastatic, liver cancers. Targeted radiotherapy by substituting the iodine in with 131Iodine (131I). Early clinical results are encouraging, but variable response may partly depend on local pharmacokinetics. This study evaluated vitro cytotoxic effects of 131I-Lipiodol human hepatocellular carcinoma (Hep-G2), colorectal metastatic cancer (SW620), hepatic (LoVo) umbilical vein endothelial cells (HUVEC) cell...
