Inherited environment

ABC, a Spanish news paper published a new where it say that a group of Scientifics of the Swiss Federal Institute of Technology Zürich had discovered that the environment leaves a mark in our brain and then a little RNA can pass the information about our experience to the next generation.

Molecular effects of MSUS in adult F1 and F2 mice

Molecular effects of MSUS in adult F1 and F2 mice

It was discovered in the psychology. The scientist Isabelle Mansuy said ”There are diseases such as bipolar disorder, that run in families but can’t be traced back to a particular gene”.  She and her team discovered that the enzymes of the RNA contain some molecules called microRNAs, which control how many copies of a particular protein are made and others functions. They are changed with traumatic stress alter and they go to the brain, the blood and the sperm and then they pass to the descendent.

But this information normally appear in the third generation  because the traumatics cases stay in the brain, in organs anf also in the gametes.

We can see this article in the ABC (a newspaper) and in the page of the ETHZ (Swiss Federal Institute of Technology Zürich), and we have the full information in the Nature Neuroscience, but it is a private document where you have pay to see it (PDF)

We can see some differences because in this type of documents the writers always change some numbers or information, but in this case the changes are not problematic.

I chose this article because it looks very interesting.

In my opinion, the discovery is good for explain how we can have feelings, in this case bad feelings, feelings that parents and a son can feel when something happened.

It does not resolve something for the sciencie that the scientists can use to treat some desease, even though it is so necessary for families interesting in this cases. Even though i hope that the sciencia will continue inventigate about this because some day we can prevent all bad things that occur in our organims.

  1. Very GOOD!

    >> You have free access to Supplementary material, where you can find a figure with the experimental design here. Maybe you’d put a more specific image in your post.

    > “…but it is a private document where you have pay to see it”. Let me show you a trick: If you paste the title of the academic article you want to see in Google, followed by “filetype:pdf”, you’ll sometimes have full access to the original article (hosted in a different web server, not in the magazine website). That’s the case this time, so I’ve examined the full text.

    >> Did you realize that this subject is almost Lamarckism?. The authors write in the introduction: ‘Recent studies have suggested that sncRNAs can mediate non-Mendelian inheritance of traits or phenotypes acquired across life’. I find this research not much reliable, specially their behavioral test. They write:

    ‘Notably, the offspring of MSUS-RNAinj mice (Injection of sperm RNAs from traumatized males) also showed depressive-like behaviors (Supplementary Fig. 13), indicating transmission of the effects of injected sperm RNAs

    But in Fig 13 you can see these results came from just 12 animals descendants of fertilized oocites injected with RNA). A really short number. In addition, these ‘depressive-like behaviors’ were estimated using the ‘Forced swim test’ which has controversial interpretation.

    >> Too much categories, you have to decide! (and everyone incompatible with ‘Uncategorized’)

    • María Espiño Albela di:

      All that you said to me is corrected.
      I put a new photo that you post in the link. I saw this photo when i saw the new, but i didn´t understand the all mean and now when i read the full pdf i can put the photo.
      Thank you for the trick, and i hope that all is better.
      I corrected the categories too.
