研究者Claudia Wellbrock表示，過(guò)去我們常常認(rèn)為癌細(xì)胞是通過(guò)特異性侵襲到機(jī)體其它組織中來(lái)進(jìn)行擴(kuò)散，但是本文研究中我們卻發(fā)現(xiàn)黑色素瘤細(xì)胞可以通過(guò)互相合作的侵襲模式來(lái)進(jìn)行擴(kuò)散;不同類型的癌細(xì)胞可以同時(shí)在腫瘤組織中存在，而且可以通過(guò)互相協(xié)作來(lái)進(jìn)行高效擴(kuò)散，這對(duì)于后期我們開(kāi)發(fā)治療性的策略往往具有一定的指示意義。
神經(jīng)調(diào)節(jié)蛋白1有不同的亞型(NRG1)，其可溶性亞型主要是由許旺細(xì)胞釋放，表達(dá)水平可決定軸突的命運(yùn)及髓鞘的厚度，尤其是軸突跨膜神經(jīng)調(diào)節(jié)蛋白1表達(dá)與創(chuàng)傷后神經(jīng)再生有密切。
意大利都靈大學(xué)神經(jīng)科學(xué)研究所神經(jīng)再生研究小組的專家們，通過(guò)研究可溶性神經(jīng)調(diào)節(jié)蛋白1在神經(jīng)損傷初期和損傷后期的表達(dá)方式及作用，顯示NRG1亞型可以成為促進(jìn)周圍神經(jīng)再生的很好的候選治療方法。相關(guān)研究觀點(diǎn)發(fā)表在《中國(guó)神經(jīng)再生研究(英文版)》雜志2014年6月第12期。
地球上所有的生物都依賴核糖體來(lái)合成蛋白質(zhì)，對(duì)于這個(gè)龐大復(fù)雜的分子機(jī)器來(lái)說(shuō)，在機(jī)體內(nèi)要經(jīng)過(guò)高度復(fù)雜和動(dòng)態(tài)的組裝過(guò)程才能形成，而且這種組裝-拆卸-再組裝的過(guò)程也是生物機(jī)體所必需的。
在這篇文章中，研究人員深入探索了與一種基因突變密切相關(guān)的神經(jīng)退行性病變過(guò)程，他們針對(duì)小鼠展開(kāi)了研究，解析小鼠中樞刪減系統(tǒng)中神經(jīng)細(xì)胞死亡的過(guò)程。
研究人員發(fā)現(xiàn)一種用于重復(fù)回收核糖體的特殊蛋白的缺失，會(huì)導(dǎo)致蛋白合成停滯不前，引起小鼠中神經(jīng)細(xì)胞死亡。之后研究人員進(jìn)一步探討這種缺失的蛋白是否會(huì)在另外不同的遺傳背景下引起同樣的問(wèn)題。但是令他們感到驚訝的是，這種蛋白的缺失只有在一種特定的遺傳背景下才能引起神經(jīng)細(xì)胞死亡，這表明核糖體相關(guān)的突變依賴于對(duì)其產(chǎn)生影響的另外一種基因。

Researchers Claudia Wellbrock said that in the past we often think that cancer cells are spread through specific invasion to other tissues in the body, but in this study, we found that melanoma cells can spread through mutual cooperation of invasion patterns; different types of Cancer cells can exist in the tumor tissue at the same time, and they can cooperate with each other for efficient proliferation. This is often indicative of the therapeutic strategies we develop in the future.
Neuregulin 1 has different subtypes (NRG1). Its soluble subtype is mainly released by Schwann cells. The expression of neuregulin 1 may determine the fate of axons and the thickness of myelin, especially the expression of axon transmembrane neuregulin 1 And post-traumatic nerve regeneration are closely linked.
Experts at the Neurorestoration Research Group of the Institute of Neurosciences at the University of Turin in Italy demonstrated that NRG1 isoform can be a good mediator of peripheral nerve regeneration by studying the expression pattern and role of soluble neuregulin 1 in the early and late stages of nerve injury Candidate treatment. Relevant research perspectives published in the "Chinese Journal of Nervous Regeneration Research (English Edition)" magazine in June 2014 No. 12.
All living things on the planet rely on ribosomes to synthesize proteins. For this hugely complex molecular machine, it takes a highly complex and dynamic assembly process in the body to form. And this assembly-disassembly-reassembly process is also done Biological body necessary.
In this article, the researchers delved into the process of neurodegeneration that is closely linked to a genetic mutation. They conducted a study of mice that resolved the process of neuronal cell death in the central nervous system of mice.
The researchers found that the absence of a specific protein for repetitive ribosome recycling led to stagnant protein synthesis and neuronal cell death in mice. Later, the researchers further explored whether this missing protein would cause the same problem in a different genetic context. What surprised them, however, was that the loss of this protein caused neuronal cell death only in a particular genetic setting, suggesting that ribosome-related mutations depend on another gene that affects them.
