Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

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 won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

科学领域:

  • 在瘤学瘤学.
  • 遗传学 是一个遗传学.
  • 病理学 病理学 病理学

背景情况:

  • 常规性和非分化性软骨瘤是产生软骨基质的恶性骨瘤.
  • 无差异性软骨肉瘤是一种具有不良预后的攻击性亚型.
  • IDH1/2,COL2A1和TP53是常见的突变基因在软骨肉瘤;IDH1/2突变也在前体病变和其他癌症中发现.

研究的目的:

  • 为了研究BCOR突变型冠状腺瘤的临床病理特征.
  • 为了确定BCOR突变是否与BCOR野生型瘤相比,与显著的生物进展模式有关.

主要方法:
