Hunter Cancer Research Alliance
As a multidisciplinary and multi-institutional alliance, the Hunter Cancer Research Alliance (HCRA) functions to provide capacity building, funding and strategic support to cancer research across the translational research continuum – from basic research through clinical trials to behavioural, implementation and health services research.
With the support of our partnering institutions, executive leaders and a membership that consists of 250+ cancer-focused researchers, we are working to promote the excellence of cancer research in the Hunter and ultimately improve cancer patient outcomes in our region and beyond.
HCRA Director, Professor Stephen Ackland, explains the work of HCRA in the video below:

Albumin Hybrid Nanoparticles Loaded with Tyrosine Kinase A Inhibitor GNF-5837 for Targeted Inhibition of Breast Cancer Cell Growth and Invasion
Vahid Heravi Shargh, Hubert Hondermarck, Mingtao Liang
Novel albumin hybrid nanoparticles (Alb-HNPs) loaded with tyrosine kinase A (TrkA) inhibitor GNF-5837 were prepared and evaluated for antineoplastic efficacy in a panel of breast cancer cell lines. The nanomedicines (GNF-Alb-HNPs, hydrodynamic diameter ~150 nm) were formed through a unique polyelectrolyte complexation process where albumin and GNF-5837 were encapsulated by a stabilizing layer of oppositely charged chitosan and dextran sulfate polysaccharides. GNF-Alb-HNPs showed an excellent colloidal stability and a sustained drug release over more than 24 hr. We found that these nanomedicines inhibited TrkA phosphorylation and downstream mitogen-activated protein kinase (MAPK) signaling in breast cancer cells specifically, resulting in anti-proliferative and pro-apoptotic effects. Moreover, the migration and invasion activities of cancer cells were dramatically suppressed and the inhibitory effects were much more prominent with GNF-Alb-HNPS than the drug
alone. These results show that the GNF-Alb-HNPs may represent a novel approach for targeted breast cancer therapy.
