Background: Plasma is an ionised gas that is typically generated in high-temperature laboratory conditions. However, recent progress in atmospheric plasmas has led to the creation of cold plasmas with ion temperature close to room temperature.
Methods: Both in-vitro and in-vivo studies revealed that cold plasmas selectively kill cancer cells.
Results: We show that: (a) cold plasma application selectively eradicates cancer cells in vitro without damaging normal cells; and (b) significantly reduces tumour size in vivo. It is shown that reactive oxygen species metabolism and oxidative stress responsive genes are deregulated.
Conclusion: The development of cold plasma tumour ablation has the potential of shifting the current paradigm of cancer treatment and enabling the transformation of cancer treatment technologies by utilisation of another state of matter.

Bladder cancer often recurs, necessitating innovative treatments to reduce recurrence. We investigated non-thermal plasma's potential as a novel anti-cancer therapy, focusing on plasma-activated solution (PAS), created by exposing saline to non-thermal plasma. Our study aims to elucidate the biological effects of PAS on bladder cancer cell lines in vitro, as well as the combination with mitomycin C (MMC), using clinically relevant settings.

Cancer remains as a global health threat, with the incidence of breast cancers keep increasing. Dis-regulated redox homeostasis has been considered with essential roles for tumor initiation and progression. Using triple negative breast cancers, the most malignant subtype of breast cancers, as the tumor model, we explored the roles of the anti-oxidant spermidine, the pro-oxidative tool cold atmospheric plasma (CAP), and their combined use in cancer growth, anti-oxidative ability and cell cycle.

Cold atmospheric plasma (CAP) has been utilized in various medical devices using its oxidative nature. Recent studies have provided evidence that CAP can facilitate the delivery of large, hydrophilic molecules through the epidermis to the dermis. On the other hand, a new approach called low-intensity CAP (LICAP) has been developed, allowing the plasma level to be controlled within a subtoxic range, thereby demonstrating various biological benefits without tissue damage.

Treatment options for recurrent high-risk non-muscle-invasive bladder cancer (HR NMIBC) and muscle-invasive bladder cancer (MIBC) are limited, highlighting a need for clinically effective, accessible, and better-tolerated alternatives. In this review we examine the clinical development program of TAR-200, a novel targeted releasing system designed to provide sustained intravesical delivery of gemcitabine to address the needs of patients with NMIBC and of those with MIBC. We describe the concept and design of TAR-200 and the clinical development of this gemcitabine intravesical system in the SunRISe portfolio of studies.

Calcium ions (Ca) are important second messengers and are known to participate in cold signal transduction. In the current study, we characterized a Ca-binding protein gene, VamCP1, from the extremely cold-tolerant grape species Vitis amurensis. VamCP1 expression varied among organs but was highest in leaves following cold treatment, peaking 24 h after treatment onset.
