Rare Metals, EarlyView.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

菠萝蛋白酶诱导K562细胞分化及其对P53基因表达的影响 [PDF]
, 1999 为进一步证实菠萝蛋白酶对肿瘤细胞的诱导分化作用，采用形态观察计数、血红蛋白定量测定、发光法测定细胞吞噬能力和Ｎｏｒｔｈｅｒｎ原位杂交法观察和检测了菠萝蛋白酶诱导Ｋ５６２细胞分化及其ｐ５３基因表达变化．结果显示，菠萝蛋白酶可诱导Ｋ５６２细胞向红系和粒／巨噬系两个方向分化；在菠萝蛋白酶作用下，ｐ５３基因于给药后８ｈ转录表达增强，２４ｈ达高峰，此后又下降，其时相变化先于分化发生．这些结果提示ｐ５３基因在Ｂｒｏｍｅｌａｉｎ诱导Ｋ５６２细胞分化过程中可能起启动分化的重要作用 ...

Study on the abnormal expression of the transcription factor FoxO3a and its mechanism in chronic myelocytic leukemia [PDF]
, 2011 背景：慢性粒细胞白血病(ChronicMyelocyticLeukemia，CML)是一种致命性的恶性造血干细胞疾病，发生源于人9号和22号染色体的易位，导致费城染色体t(9;22)(q34;q11)和融合蛋白P210BCR/ABL的形成。P210BCR/ABL显示异常增强的酪氨酸激酶活性，过度激活下游Ras、PI3K/Akt等信号通路导致肿瘤的发生。FoxO蛋白家族作为转录因子通过调节细胞内多种重要基因的表达，而介导细胞周期、DNA损伤修复、凋亡、氧化应激、细胞分化代谢等细胞生理过程 ...

Rare Metals, EarlyView.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...
