Michelakis 说：“我们惊讶地发现，尽管早就认识到了组蛋白乙酰化在细胞生物学和医学中的重要性，尽管许多人付诸了努力来开发调控组蛋白乙酰化的药物，但对于细胞核中乙酰辅酶A的来源仍不清楚。有时候一些重要的生物学问题的答案就在我们身边，等待着我们去发现。”
该研究小组发现PDC易位到细胞核中使得癌细胞以更快的速度生长，这一发现或许可促成抗癌战争其他的一些策略。由于这些研究结果与一般情况下我们的DNA调控有关，这项研究有可能对于表观遗传调控起至关重要作用的、许多生理和病理情况产生更广泛的影响。“发现将能量生成(新陈代谢过程)与基因调控在一起的这一新信号通路，我们感到非常的兴奋，”研究人员说。
根据science上一篇文章介绍，一种细胞应激通路称为未折叠蛋白反应(UPR)既可以激活也可以降低死亡受体5蛋白(DR5)，它能促进或预防细胞抗原抗体。该理论认为初始应激阻止细胞抗原抗体或凋亡，以使细胞有机会去适应，但是如果应激持续下去，它zui终触发凋亡。
普林斯顿大学分子生物学教授Alexei Korennykh说“这项研究使得所有这种大的复杂的烂摊子的zui美丽简化。基本上，他们识别和精确定位与这一开关决定有关的特殊蛋白并解释这一决定是怎么做的。”但是加利福尼亚拉霍亚伯纳姆医学研究所的Randal Kaufman 并没有留下深刻印象。他怀疑支持作者主要理论关于这一关键细胞过程的实验生理学关联性。
细胞中蛋白折叠多数发生在内质网(ER)，但是如果这个过程出现差错，未折叠蛋白累积，对ER产生应激。这可触发UPR，关闭翻译，降低未折叠蛋白，增加蛋白质折叠机制的产生。然而，如果ER应激没有解决，UPR也能诱导凋亡。
两个主要因素控制UPR-IRE1a和PERK。IRE1a通过激活转录因子XBP1促进细胞存活，驱动细胞存活基因的表达。另一方面，PERK激活一种转录因子称为CHOP，它反过来驱动促凋亡因子DR5的表达。
旧金山加州大学Peter Walter及其同事现已证实CHOP激活DR5，表明它是一种细胞自主过程。但是他们也发现IRE1a抑制DR5，直接降解它的mRNA通过一种称为调节IRE1a依赖的降解(RIDD)过程。人类癌细胞系出于ER应激中的IRE1a抑制即可以防护DR5 mRNA降解又可以增加细胞凋亡。

"We were surprised to find that although the importance of histone acetylation in cell biology and medicine has long been recognized, and despite the many efforts that have been made to develop drugs that regulate histone acetylation, in the nucleus The source of acetyl-CoA remains unclear, and sometimes the answers to some of the key biological questions are right around us, waiting for us to discover. "
The team's discovery that PDC translocates to the nucleus to allow cancer cells to grow at a faster rate may have led to other strategies to fight cancer. Since these findings are linked to our DNA regulation in general, this study is likely to have a broader impact on many physiological and pathological conditions, which are crucial for epigenetic regulation. "We are excited to find this new signal pathway linking energy production (metabolic processes) to gene regulation," the researchers said.
According to an article in science, a cellular stress pathway called unfolded protein response (UPR) activates or reduces the death receptor 5 protein (DR5), which promotes or prevents cellular antigen antibodies. The theory holds that initial stress prevents cellular antigen antibodies or apoptosis, so that cells have a chance to adapt, but it eventually triggers apoptosis if stress persists.
Alexei Korennykh, a professor of molecular biology at Princeton University, said: "This study makes the most beautiful simplification of all this big, complex mess, and basically they identify and pinpoint specific proteins that are relevant to this switch decision and explain that What to do. "But Randal Kaufman of La Jolla Burnham Medical Institute in California did not impress. He doubted his support for the author's primary theory of the experimental physiology of this crucial cellular process.
The majority of protein folding in cells occurs in the endoplasmic reticulum (ER), but if there is a mistake in this process, unfolded protein accumulates, stressing the ER. This triggers UPR, turning off translation, reducing unfolded proteins, and increasing the production of protein folding mechanisms. However, UPR also induces apoptosis if ER stress is not resolved.
Two major factors control UPR-IRE1a and PERK. IRE1a promotes cell survival by activating the transcription factor XBP1, driving the expression of cell-survival genes. On the other hand, PERK activates a transcription factor called CHOP, which in turn drives the expression of pro-apoptotic factor DR5.
Peter Walter and colleagues at the University of California, San Francisco, have now shown that CHOP activates DR5, indicating that it is a cell-autonomous process. However, they also found that IRE1a inhibits DR5 by directly degrading its mRNA through a process called regulation of IRE1a-dependent degradation (RIDD). Human cancer cell lines protect DR5 mRNA from degradation and increase apoptosis as well, due to IRE1a inhibition in ER stress.
