- 遗传学 是一个遗传学.
背景情况:
- 脑膜瘤占原发性脑瘤的40%;3级 (形) 脑膜瘤是罕见的 (1.5%),但具有攻击性.
- 诊断依赖于组织病理学和分子标记,以世界卫生组织 (WHO) 中枢神经系统 (CNS) 瘤分类为指导.
- 3级脑膜瘤表现出恶性细胞形态,高线粒活性和特定的遗传变异 (TERT促进体突变,CDKN2A/B删除).
研究的目的:

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
