概括
这项关于门癌 (AC) 的研究揭示了人类乳头瘤病毒 (HPV) 基因表达模式和宿主免疫反应与癌症复发相关. 识别这些病毒和宿主因素可能会导致门癌的新疗法.
科学领域:
- 在瘤学瘤学.

背景情况:
- 门状细胞癌 (SCCA) 影响着艾滋病毒感染者 (PWH),特别是与男性发生性关系的男性 (MSM).
- 门癌 (AC) 的复发率很高 (大约. 在标准化疗辐射疗法 (CRT) 后,25%).
- 以前的研究表明,在非复发性 (NR) 与复发性 (R) AC中,免疫基因表达是不同的,但HPV和宿主相互作用的作用仍未得到充分研究.
研究的目的:
- 调查特定的人类乳头瘤病毒 (HPV) 基因型和基因表达模式是否区分复发性和非复发性门癌症 (AC).

Non-LTR Retrotransposons
11.3K
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...

Mechanisms of Retrovirus-induced Cancers
4.9K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Rous Sarcoma Virus (RSV) and Cancer
4.9K
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.

Initiation of Translation
29.8K
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...
