Cancer drugs that stimulate the body’s immune system to attack tumors are a promising way to treat many types of cancer. However, some of these drugs produce too much systemic inflammation when delive...
Cancer cells selectively load ‘drones’ to keep T cells from infiltrating tumors（图）
癌细胞 选择性加载 T细胞 浸润肿瘤

Checkpoint inhibitor drugs have been a gamechanger for many cancer patients. Yet around 70% don’t respond to these medications, which work by removing the “brakes” on the immune system’s response to a...
A new method could enable a patient’s own antibodies to eliminate their tumors（图）
肿瘤免疫学 抗体 靶向治疗
2023/7/10
One of the reasons that cancer is notoriously difficult to treat is that it can look very different for each patient. As a result, most targeted therapies only work for a fraction of cancer patients. ...
Over time, cancer cells can evolve to become resistant to treatment, more aggressive, and metastatic — capable of spreading to additional sites in the body and forming new tumors. The more of these tr...
A stealthy way to combat tumors（图）
抗肿瘤 辅助免疫细胞 T细胞
2023/6/6
Under the right circumstances, the body’s T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor.
Solid, liquid, or gas? Technique quickly identifies physical state of tissues and tumors（图）

Physicists at The University of Texas at Arlington have shown that using microwaves to activate photosensitive nanoparticles produces tissue-heating effects that ultimately lead to cell death within s...
Stiffer breast tissue in obese women promotes tumors
Stiffer breast tissue obese women promotes tumors
2015/9/9
Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published this month in Science Translational Medicine explains how ...
Drugs that target insulin pathways to slow or stop the growth of brain tumors are going in the right direction but appear to be on the wrong track, according to new research at Rice University.Through...
Enzymes Believed to Promote Cancer Actually Suppress Tumors
Enzymes Believed Promote Cancer Suppress Tumors
2015/3/4
Upending decades-old dogma, a team of scientists at the University of California, San Diego School of Medicine say enzymes long categorized as promoting cancer are, in fact, tumor suppressors and that...
Engineering breakthrough will allow cancer researchers to create live tumors with a 3-D printer
Engineering breakthrough allow cancer researchers create live tumors 3-D printer
2014/5/13
Drexel’s Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish.

Most human cells have 23 pairs of chromosomes, the large bundles of DNA that store all of a cell’s genetic information. However, scientists realized more than 100 years ago that tumor cells usually ha...
This study is a survey type of work on the plant tumors and their characteristics in genera1; special attention is given to those tumors which are caused by grobacterium tumefactions and also by plant...
