10-12-23 A class of drugs thought to kill cancer cells may in fact block cross talk between the cancer cell and normal immune cells, resulting in reduced cancer growth and spreada discovery that could significantly alter the way cancer drugs are evaluated in...
10-12-13 The presence of one to four circulating tumor cells ( CTCs肿瘤细胞 ) in the blood of early-stage breast cancer patients almost doubled patient's risk of cancer relapse and death, and five or more CTCs increased recurrence by 400 percent and death by...
10-12-13 Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular(睾丸的) tissue, say Georgetown University Medical Center (GUMC) researchers who presented their findings today at the American Society of Cell Bio...
10-12-06 Damage caused by multiple sclerosis(多发性硬化) could be reversed by activating stem cells that can repair injury in the central nervous system, a study has shown. Researchers from the Universities of Cambridge and Edinburgh have identified a mech...
10-12-03 A novel type of biomedical imaging, made possible by new advances in microscopy from scientists at Harvard University, is so fast and sensitive it can capture video of blood cells squeezing through(挤过,勉强通过) capillaries(毛细血管) . Researc...
10-12-02 A gene that controls part of the 'tick tock' in a plant's circadian(生理节奏的) clock has been identified by UC Davis researchers. And not only is the plant gene very similar to one in humans, but the human gene can work in plant cells -- and vice...
10-11-24 Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis(转移,新陈代谢) , are stimulated by estrogen(雌性激素) via a pathway that mirrors normal stem cell develo...
10-11-19 A potent(有效的,强有力的) anti-tumor gene introduced into mice with metastatic(转移性的,变形的) melanoma(黑素瘤,胎记瘤) has resulted in permanent immune reconfiguration and produced a complete remission(缓解,豁免) of their cancer, accord...
10-11-01 In a study of mice with lymphoma(淋巴瘤) , MIT biologists have discovered that a small number of cancer cells escape chemotherapy(化学疗法) by hiding out in the thymus(胸腺) , an organ where immune cells mature. Within the thymus, the cancer c...
10-11-01 Scientists from the UK and Australia have seen the human immune system's assassin a protein called perforin(穿孔素) in action for the first time. The UK team, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Wel...
