概括

研究温度对状细胞活力的影响表明,中等温度 (40°C) 增强了细胞活动,而较高温度 (≥44°C) 降低了细胞活动. 像Ras和MAPK这样的关键分子通路,以及Agt等基因,都参与了这种温度依赖的调节.

科学领域:

细胞生物学细胞生物学
分子生物学分子生物学
生物技术是生物技术.

背景情况:

之前的研究表明,微波除 (MWA) 有效地调节小猪的生长板.
这项研究的重点是了解不同温度对状细胞活力和分子机制的体外影响.

研究的目的:

为了确定不同温度对状细胞 (ATDC5) 活力的影响.
阐明分子通路和关键基因,涉及温度诱导的变化,在红细胞.

主要方法:

在10分钟内,ATDC5细胞暴露在37°C至50°C的温度下.
使用CCK-8试验评估了细胞活力.
RNA测序 (RNA-seq) 在37°C,40°C和44°C确定了差异表达基因 (DEG) 和枢纽基因;RT-qPCR验证了基因表达.

主要成果:

与37°C相比,40°C的温度显著增加了ATDC5细胞活力;温度≥44°C降低了活力,在≥46°C显著损失.
RNA-seq揭示了参与增殖,分化,亡,免疫反应和ECM重塑的DEGs,与Ras,PI3K/AKT,mTOR,cAMP和MAPK通路相关.
鉴定出Agt,HSpa1a,HSpb1和NLrc4是枢纽基因,其表达模式通过RT-qPCR得到证实.

结论:

冠状细胞活力由温度调节,涉及Ras,PI3K/AKT,mTOR,cAMP和MAPK信号通路.
Agt,HSpa1a,HSpb1和NLrc4被确定为温度依赖性冠状细胞反应中的潜在关键调节基因.

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Chromatin Position Affects Gene Expression

Chromatin Position Affects Gene Expression

Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.
