They are called tumor-associated macrophages (TAMs), which are classified to alternative polarization that is simply called M2 polarization. Monocytes, one of the most prominent components, are recruited in tumor tissues and are polarized to tumor-supporting macrophages, instead of the well-known inflammatory M1 polarized one. ![]() It is typically characterized by low oxygen, low pH, high lactate, high RNS, etc., which results in differentiated responses of cellular components. It is well known that cancer cells create microenvironments that support their growth and suppress antitumor immune activities. One of the important factors in anticancer treatment is the microenvironment of cancer tissues. In this study, we generated PAW that mainly contained RNS and applied them to innate immune cell macrophages, to study their polarized differentiation especially when they interact with cancer cells. In general, ROS induces oxidative stress which can generally activate redox responses in cells meanwhile, RNS induces nitrosylation or nitrosation which initiates different cellular signaling pathways that are known to be related to cell differentiation or the wound-healing process. The actions of reactive oxygen species (ROS) and reactive nitrogen species (RNS) are distinguished in biological systems. Since PAM contains relatively long-lived reactive species compared to direct plasma treatment, hydrogen peroxide and nitric oxide ions were identified as the main players in PAM reactivity. Many researchers have tried to understand the working mechanisms of PAM in its tumoricidal activity. PAM does not have any possibility of electrical hazards, it can be stored at low temperature for a certain period, and it can be injected into any part of the body. ![]() PAW or PAM has several merits comparing to the direct plasma treatment. Recently, plasma-activated water (PAW) or media (PAM) has been introduced as an effective solution in killing various kinds of cancer cells, including ovarian cancer, cervical cancer, pancreatic cancer and glioblastoma. Our results show that PGNO-solution has the potential to convert the fate of macrophages, suggesting PGNO-solution treatment as a supportive method for controlling the function of macrophages under the tumor microenvironment. The anticancer potential was also investigated in a syngeneic mouse model. In addition, the PGNO-solution-treated M2-like macrophages had higher potential in killing melanoma cells. PGNO-solution upregulates M1-type macrophage activation and downregulates the characteristics of M2-type macrophage at the transcriptional level. The RNS-containing water was diluted in complete cell culture media (PGNO-solution) into the concentration that did not induce cell death in RAW 264.7 murine macrophages. In this study, we generated RNS-containing water treated with microwave plasma-generated gas in which the major component was nitric oxide (PGNO), and the effect on the macrophage polarization was investigated. It’s about using the best out of our current tools – and Workflowy certainly ranks highly up there.Reactive nitrogen species (RNS), including nitric oxide (NO ⋅) has been known as one of the key regulatory molecules in the immune system. They are still bits and pieces of information in there, left in a corner, deprived of my attention.Īs I ponder upon the purchase of Writer Pro, I realize what I need is not something new. I take it as a nudge for me to revisit the service which used to be central location to store my ideas and to-do lists. Finally, we are able to use it practically anywhere. Today, they introduce the offline feature. Wonderful product like Workflowy, which I wrote about a year ago. I’m neglecting the existing ones I have to cast a gleeful glance at the others. ![]() Some powerful ones which I have no use of, but the urge to just own them is just as strong. I just do what I’m supposed to do in there – write. When I first started using IA Writer, the simple interface with no settings to tweak is a breath of fresh air. When the news of Writer Pro filters through, many people are excited and some are eagerly anticipating its launch.
