研究的目的:

调查外子切换在T细胞衰老期间调节CD5表达中的作用.
阐明IL-10和CEBP-β在与年龄相关的CD5表达变化的参与.

主要方法:

从年轻和老年人的T细胞中分析E1A和E1BmRNA表达.
评估IL-10对T细胞外子切换和CEBP-β活性 (异形表达,DNA结合) 的影响.
利用短发针RNA (shRNA) 沉默CEBP-β并确认其在E1A/E1B调节中的作用.

主要成果:

老年人表现出增加的E1B和减少的E1AmRNA表达,反映了IL-10治疗的年轻T细胞.
IL-10调节的CEBP-β结合E1A和E1B调节区域和上调的抑制CEBP-β异型.
CEBP-β静音降低了E1B的表达,证实了它的调节作用.

Mechanisms of Retrovirus-induced Cancers

Mechanisms of Retrovirus-induced Cancers

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...
