概括
人类乳头瘤病毒 (HPV) 16型E6基因转录在50%的非子宫内膜癌 (EC) 中被发现,但在子宫内膜癌中没有. 在淋巴结转移中没有检测到HPV,即使在HPV阳性原发性瘤中也是如此.
科学领域:
- 妇科瘤学 妇科瘤学

- 了解HPV在EC病变发生中的作用对于向治疗至关重要.
研究的目的:
- 调查HPV16DNA E6/E7转录在各种EC亚型中的发生率.
- 为了确定HPV16 E6/E7转录是否与特定的EC临床病理特征相关.
- 在EC的淋巴结转移中检查HPV16的存在.
主要方法:
- 基于聚合酶链反应 (PCR) 的技术被用于检测HPV16 DNA E6/E7转录.
- 在HPV16阳性病例中进行了免疫组织化学染色.
- 七个淋巴结转移被分析为HPV16 DNA E6/E7.7.
主要成果:
- 检测到HPV16 E6转录在50%的II型 (非子宫内膜体) EC中,包括 papillary-serous和清细胞亚型.

Non-LTR Retrotransposons
11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

The Retinoblastoma Gene
4.1K
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 damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Initiation of Translation
33.8K
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Metastasis

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) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
