線粒體活性的增加實際上會適度刺激氧化應激(自由基損傷)和相關的DNA損傷。雖然DNA損傷似乎不利于長壽養(yǎng)生，但低程度DNA損傷實際上減少了細胞的增殖，減慢生長速度，使細胞的自然修復機制生效。
總之研究發(fā)現(xiàn)TRAP-1基因敲除小鼠表現(xiàn)出較少的與年齡相關的病癥包括肥胖，炎癥組織變性和自發(fā)形成的腫瘤等。
在加州大學圣地亞哥醫(yī)學院神經(jīng)修復中心主任、神經(jīng)科學教授Mark Tuszynski博士和同事們將源自于一名86歲的健康男性的皮膚細胞轉(zhuǎn)化為iPSCs后，研究小組將iPSCs重編程為神經(jīng)元，把這些神經(jīng)元放入到包含一些生長因子的基質(zhì)中，然后研究人員再將它們移植到了脊髓損傷達2周的大鼠體內(nèi)。
3個月后，研究小組在大鼠脊髓中發(fā)現(xiàn)了成熟的神經(jīng)元，神經(jīng)纖維跨越長距離廣泛的生長，通過了損傷組織甚至延伸到了大腦中。盡管移植神經(jīng)元和大鼠神經(jīng)元之間存在大量的，但動物肢體的功能尚未得到恢復。研究人員指出，幾個iPSC移植物都具有一些抗原抗體，有可能阻斷了有益效應。
Tuszynski博士說：“這些結(jié)果表明，內(nèi)在神經(jīng)元機制可以輕易地克服脊髓損傷建立的障礙，將許多的軸突延伸很長的距離，且這些能力甚至在由非常老化的人類細胞重編程的神經(jīng)元中持續(xù)存在。”
Tuszynski和Paul Lu以及合作者們，現(xiàn)正致力于鑒別利用來自患者自身細胞的移植物，轉(zhuǎn)化神經(jīng)干細胞療法用于脊髓損傷患者的途徑。
在人類的健康腸道中，干細胞會不斷地彼此競爭得以生存，而在某一個時間某一個腸道區(qū)域往往只會存在一種特定數(shù)量的干細胞生存下來;然而當研究者調(diào)查早期腫瘤組織中的干細胞時，他們卻發(fā)現(xiàn)隨著干細胞生存競爭的劇烈增加，干細胞的數(shù)量也在相應增加，這就明顯揭示了腸癌發(fā)生和干細胞活性之間的關系。
文章中，研究者利用一種特殊開發(fā)的“工具盒”對人類機體的干細胞進行研究，這種新型工具盒可以隨機測定老化干細胞的突變情況，這種突變情況正表明了干細胞所發(fā)生的行為;在本項研究開展之前，關于人類腸道干細胞生物學的分子機制依然是個謎，而在這篇研究報道中研究者就解開了這一謎題;研究者利用小鼠進行試驗，由于小鼠的腸道特性和人類的腸道特性具有明顯的相似性，因此利用小鼠進行研究得到的結(jié)果就可以轉(zhuǎn)化到人類機體中。

Increased mitochondrial activity can actually moderay stimulate oxidative stress (free radical damage) and related DNA damage. Although DNA damage seems to be detrimental to longevity, low levels of DNA damage actually reduce cell proliferation, slow the rate of growth and allow the cell's natural repair mechanism to work.
In conclusion, the study found that TRAP-1 knockout mice showed less age-related disorders including obesity, inflammatory tissue degeneration and spontaneous formation of tumors.
After skin cells, director of the University of California, San Diego School of Medicine Center for nerve repair, a professor of neuroscience, Dr. Mark Tuszynski and colleagues will be derived from a 86-year-old healthy men into iPSCs, the team will iPSCs reprogrammed into neurons, the The neurons were placed in a matrix containing some of the growth factors, and the researchers then transplanted them into rats that had been injured for up to two weeks.
Three months later, the team found mature neurons in the rat spinal cord, which grew extensively over long distances, damaged tissues and even extended into the brain. Despite the large number of connections between transplanted and rat neurons, the function of animal limbs has not been restored. Researchers pointed out that several iPSC implants have some antigenic antibodies, potentially blocking the beneficial effects.
Dr. Tuszynski said: "These results suggest that internal neuronal mechanisms can be easily overcome obstacles to the establishment of spinal cord injury, many of the axons extend long distances, and these capabilities even by a very aging reprogrammed human nerve cells in yuan In the persistence. "
Tuszynski and Paul Lu and collaborators are now working on identifying the best ways to use neural stem cell-based therapies for patients with SCI using grafts from their own cells.
In the human gut health, stem cells will continue to compete with each other to survive, but in a certain area of ??the intestine often only a certain time there is a certain number of stem cells survive; however, when the researchers examined the early tumor tissue stem cells They found that as the number of stem cells increased with the dramatic increase in competition for stem cell survival, this clearly revealed the relationship between colorectal carcinogenesis and stem cell activity.
Article, the researchers used a specially developed "tool box" of the human organism stem cell research, this new tool box can be random mutation assay aging stem cells, this mutation show a positive behavior of stem cells occurred; prior to this study, carried out the molecular mechanisms of human intestinal stem cell biology is still a mystery, but in this study the researchers report on solved the puzzle; the researchers used mice to test, because the mouse Of the intestinal traits and human intestinal characteristics have obvious similarities, so the results of the study using mice can be transformed into the human body.
