Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially ...
癌症起源于单个细胞中的体细胞突变
癌症起源于单个细胞中的体细胞突变
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate ...
肿瘤进展
肿瘤进展
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the ...
癌细胞的适应性机制
癌细胞的适应性机制
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, ...
肿瘤微环境
肿瘤微环境
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood ...
转移
转移
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) ...
癌症关键基因 I:原癌基因
癌症关键基因 I:原癌基因
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, ...
逆转录病毒诱导癌症的机制
逆转录病毒诱导癌症的机制
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of ...
<em>Ras</em> 基因
Ras 基因
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family ...
肿瘤抑制基因功能丧失
肿瘤抑制基因功能丧失
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable ...
mTOR 信号转导和癌症进展
mTOR 信号转导和癌症进展
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a ...
癌症干细胞和肿瘤维持
癌症干细胞和肿瘤维持
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often ...
癌症小鼠模型研究
癌症小鼠模型研究
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are ...
防癌
防癌
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular ...
癌症治疗
癌症治疗
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients. However, ...
靶向癌症治疗
靶向癌症治疗
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between ...
难治性癌症
难治性癌症
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify ...
联合疗法和个性化医疗
联合疗法和个性化医疗
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a ...
癌症关键基因 II:肿瘤抑制基因
癌症关键基因 II:肿瘤抑制基因
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, ...
视网膜母细胞瘤基因
视网膜母细胞瘤基因
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable ...
Rous 肉瘤病毒 (RSV) 和癌症
Rous 肉瘤病毒 (RSV) 和癌症
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He ...
