Antitumor Therapy

Our article was about a medicine that may potentially slow down or even stop tumor growth. On page 1 of the article, “A Nano-strategy for the Efficient Imaging-Guided Antitumor Therapy through a Stimuli-Responsive Branched Polymeric Prodrug,” highlights the significance of the nano-medicine and the positive effect it can give to eliminate a tumors process.  Scientists modified nano particles to create the drug and  used mice during an experiment to test the effects of the prodrug on tumors; they recorded the data. Usually, cancer is a disease in which cells divide uncontrollably and quickly. Therefore, any data that demonstrates a decrease in volume, weight, or size of the tumor shows that cancer has stopped growing and is instead going away. On page 11 of the article, there are a series of graphs and tables which all support the idea that a drug labeled NPS may have the ability to inhibit tumor growth. In Figure A on page 11, readers see how amongst the three injective drugs given to the mice in the experiment, only NPS, which was the drug that the article was about, decreased the size of the tumor. The images in figure A are further supported by the images and graphs below in figures B, C, and D. In figure B, for the data concerning taxol and saline, the tumor volumes continue to increase gradually.

In contrast, with NPS, the volume decreases. In figure C, actual photos of the tumors are provided, and readers once again are shown how with NPS, the tumor gets continuously smaller until it completely disappears, whereas the tumors treated with the other substances are still there. Similar to figure B, the tumor weight shown by figure D is the smallest for the tumors treated by NPS while the biggest for the tumors treated with saline. Volume, weight, and the MRI photos all support the concept that this drug may work in terminating or slowing down cancer because, in all cases, it has been shown to help slow down the progression of the disease.
