Abstract
Nonequilibrium atmospheric pressure plasma (NEAPP) is a novel approach for blood coagulation, wound healing, and tumor elimination. NEAPP not only directly but also indirectly affects living cells via the medium exposed to NEAPP-yielding devises, called plasma-activated medium (PAM). The conservable and portable PAM serves as an alternative and advantageous approach over direct NEAPP. Here we examined the effect of PAM on lymphoplasmacytic lymphoma (LPL) cell lines. We found that PAM induced plasma cell differentiation and reduced tumorigenic population. PAM increased the expression level of PRDM1α, which is a transcription factor promoting plasma cell differentiation, suggesting that plasma cell differentiation of LPL might be mediated by PRDM1α. We previously reported that plasma cell component of LPL is vulnerable to apoptosis and less tumorigenic. These findings suggested that PAM treatment might become a novel therapy against LPL by inducing the transition from tumorigenic to non-tumorigenic population.
