Dear Guests and Participants,

On behalf of the International Society of Nitric Oxide and Cancer (ISNOC) it is our great pleasure to welcome you to the 9th International Workshop on Nitric Oxide and Cancer, scheduled to take place in Dijon, France, on September 8-10, 2025.

We are thrilled to host a gathering of experts to explore the complex role of nitric oxide (NO) in cancer. The event will explore key topics, including the role of NO and other gaseous signaling molecules in regulating tumor oxidative stress, inflammation, and the progression of tumor development. A central focus of the meeting will be the reprogramming of the tumor microenvironment, which is rapidly emerging as a crucial strategy in cancer therapy. We will examine the significant impact of NO on immune modulation, cellular metabolism, angiogenesis, and epigenetic factors for example. Additionally, we will explore how strategies that modulate NO levels—such as iNOS inhibition or NO donor therapy—can alter the characteristics of the tumor microenvironment cells to enhance treatment outcomes.

Our program includes keynote addresses from distinguished scientists, oral and poster presentations. We are confident that the knowledge shared and the connections made during this congress will pave the way for future innovations.

We sincerely thank our speakers, sponsors and all participants for their valuable contributions and support.

Sincerely yours,
