大鼠坐骨神经切断后相应脊髓节段Bcl-2、Bax蛋白表达及神经细胞凋亡
Zhongguo shiyan zhenduanxue, 2010 目的探讨成年大鼠坐骨神经切断后相应脊髓节段Bcl-2、Bax蛋白表达及神经细胞凋亡。方法选取健康成年雄性Wistar大鼠35只,随机分为假手术组（5只）和实验组（30只）。实验组再分为六个小组,每组5只。实验组于伤后3天,1周,2周,4周,6周和8周6个时间点取材。应用TUNEL法和免疫组化染色法检测神经细胞的凋亡及脊髓Bcl-2、Bax蛋白表达。结果大鼠坐骨神经切断后3天即可见脊髓内TUNEL阳性细胞,2周表达到达高峰,此后表达量逐渐下降;大鼠坐骨神经切断3天后凋亡相关蛋白Bcl-2和Bax出现表达 ...

Advanced Science, EarlyView.RGS16 competitively interferes with the YTHDF3–PAN3 complex to prevent CXCL1 mRNA decay during hepatic ischemia‐reperfusion injury. Stabilized CXCL1 strengthens hepatocyte injury, neutrophil recruitment, and NET‐associated inflammation, uncovering how stress‐induced RGS16 converts post‐transcriptional regulation into immune‐mediated liver damage ...

Advanced Science, EarlyView.Schematic representation of ultrasound‐mediated ICG/siCD24@MSN‐LCD from nanostructure to synergistic sono‐gene therapy. This nanoplatform targets ASGPR via the LCD shell, which dissociates to release loaded ICG and siCD24. The core mechanism involves ultrasound‐guided sonodynamic therapy by ICG and CD24 knockdown by siCD24, both activating the p53 axis

Advanced Science, EarlyView.PTEN knockdown activates AKT phosphorylation, promoting Nrf2 nuclear translocation and STAT3 activation, which upregulates GPX4 and antioxidant enzymes HO‐1, SOD1, SOD2, and NQO1. These coordinated changes reduce lipid peroxidation and ROS, inhibit ferroptosis, and ultimately ameliorate cognitive impairment in APP/PS1 transgenic mice, highlighting a ...

Animal Models and Experimental Medicine, EarlyView.D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.
