Prof. Kaye j Williams is the Leader of the Hypoxia and Therapeutics Group within the Division of Pharmacy and Optometry at the University of Manchester. Prof. Williams joined DPO in November 1996. Following back-to-back research associate and research fellow positions funded by the MRC, she gained tenure in January 2006, and was promoted to Chair in Experimental Therapeutics and Imaging in August 2012. Her research focuses on the tumour microenvironment, investigating therapeutic targets, vascular biology and molecular interactions that influence tumour response to radiotherapy. Prof. Williams also leads pre-clinical imaging development within the Manchester Cancer Research Centre, and has leadership for preclinical imaging within Imaging@Manchester. Externally, she has had significant roles in the NCRI Clinical and Translational Radiotherapy Research Working Group, in particular through association with the RadCom initiative that aimed to expedite novel drug radiation combinations into clinical trials. She continues to provide leadership in this area via the CRUK Drug–Radiotherapy Working Group. She is part of the team that secured £16.5 million for the University of Manchester towards infrastructure funding in radiation-related research via the CRUK RadNET initiative and currently acts as Deputy Director of CRUK RadNET Manchester. She was awarded the British Association for Cancer
Research/AstraZeneca Frank Rose Young Scientist Award in 2005.

Prof. Ian J Stratford obtained a B.Sc in Chemistry from the University of Exeter and subsequently a PhD in Radiation Biology from Manchester University where he is now Professor of Pharmacy. He secured continuous programme grant support from the Medical Research Council between 1981 and 2010 and in addition, secured sustantive funding from the cancer charities and industry. He currently leads a small team of post-graduates and research associates and the focus of their research is twofold: 1. to enhance the effects of radiotherapy by using molecularly targeted drugs and 2. to exploit tumour energy metabolism to improve cancer therapy. In 2015, Prof. Stratford was awarded the Weiss Medal at the quadrennial International Congress for Radiation Research for contributions to and achievements in radiation research.

Abstract
Background/Objectives: Conventional anticancer therapies often lack specificity, targeting both cancerous and normal cells, which reduces efficacy and leads to undesired off-target effects. An additional challenge is the presence of hypoxic regions in tumors, where the Hypoxia Inducible Factor (HIF) transcriptional system drives the expression of pro-survival and drug resistance genes, leading to radio- and chemo-resistance. This study aims to explore the efficacy of targeted nanoparticle (NP)-based small interfering RNA (siRNA) therapies in downregulating these genes to enhance treatment outcomes in pancreatic cancer, a tumor type characterized by high CD44 expression and hypoxia. Methods: We utilized hyaluronic acid (HA)-displaying nanoparticles composed of positively charged chitosan (CS) complexed with siRNA to target and knock down HIF-1α in pancreatic cancer cells. Two NP formulations were prepared using either low molecular weight (LMW) or high molecular weight (HMW) CS. These formulations were evaluated for their internalization by cells and their effectiveness in gene silencing, both in vitro and in vivo. Results: The study found that the molecular weight (MW) of CS influenced the interaction between HA and CD44, as well as the release of siRNA upon internalization. The LMW CS formulation shows faster uptake kinetics, while HMW CS is more effective in gene knockdown across different cell lines in vitro. In vivo, both were able to significantly knockdown HIF-1α and some of its downstream genes. Conclusions: The results suggest that HMW and LMW CS-based NPs exhibit distinct characteristics, showing that both MWs have potential for targeted pancreatic cancer therapy by influencing different aspects of delivery and gene silencing, particularly in the hypoxic tumor microenvironment.
