I have a question that isn't quite related to epigenetics but more to something you mentioned-- You said that Chromatin Packing has a governing effect on processes including apoptosis. How could this be the case? Do cells willingly undergo apoptosis or is it the same thing as lysing the cell itself? I've only heard the word apoptosis used in the context of osmosis from a hypotonic(I think) solution being an environment in which cells will explode.

@omicslogic

3 жыл бұрын

Apoptosis is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. It is regulated by certain genes which trigger this process. These genes can be more accessible for translation as a result of chromatin accessibility.

Muito obrigado.

I was under the impression that it was recently discovered that methylation has inherited to some extent.

@omicslogic

3 жыл бұрын

Transgenerational epigenetic inheritance, (TEI), is the transmission of epigenetic markers from one organism to the next (i.e., parent-child transmission) that affects the traits of offspring without alteration of the primary structure of DNA (i.e. the sequence of nucleotides) - in other words, epigenetically.

@@omicslogic thanks for answering me! I understand, right. But I wonder why some methylations repress gene expression and other methylations are positive marks for gene expression. Why is that? I used to think that,for example, acetylation was an "active" mark and methylation was always a "repressive" mark. Thanks

A bit of confusion in that it is not clear which processes are naturally occurring and which are done in the lab.

it is an introduction to a much more complex and technical course, for more high level overviews plenty of youtube videos can be found as well. You can learn more here: learn.omicslogic.com

This mono-tonal recitation of a poorly written textbook is more confusing than helpful. This format might be ok for someone reviewing epigenes, but as an introduction to a newbie, not so good. And it is a pity since whoever created this did a lot of work. I feel bad writing this public criticism, but this is more helpful to you than a glowing compliment. Another thought you might consider is to only put up images that make a specific point. Textbooks are stuck having to fit the text and images together, but a living narrator has the choice of what images to show the audience. By synchronizing the narration and images, difficult ideas can be clarified much better than they can be on a printed page. Bottom line... look at this presentation as a two pillar approach to understanding concepts... and make sure both pillars are working together. Thankfully there was no music. That would have made it unbearable.

@@omicslogic I'm a biomedical graduate student, and I have to say, I strongly disagree with this critique. The subject was properly detailed, perhaps with the exception of trivial historical details. I find that students taking intro bio and genetics courses struggle to keep pace with this type of lecture due to their reliance on things like Khan academy, and the simplified verbiage used to explain these topics. Overall I think this is a good lecture, concise, and generally without errors or outdated information. If a student wants to pursue meaningful research of these topics, this is generally what they will hear and be expected to digest in their studies.
