Iron-sensitive RNA regulation by poly C binding proteins [P1KD]

Iron is important for normal cellular function and posttranscriptional mechanisms regulate the cellular response to iron deficiency. In this study we explore how RNA binding proteins, PCBP1 and PCBP2, exhibit iron-sensitive RNA regulation. Overall design: K562 cells were transduced to express short hairpin RNAs targeting luciferase (shCtrl) or PCBP1 (shPCBP1).

铁对正常细胞功能至关重要，转录后机制可调控细胞对铁缺乏的应答反应。本研究探讨了RNA结合蛋白PCBP1与PCBP2如何发挥铁敏感性RNA调控作用。整体实验设计：将K562细胞转导以表达靶向荧光素酶的短发夹RNA（short hairpin RNAs，shCtrl）或靶向PCBP1的短发夹RNA（shPCBP1）。
