- This lecture introduces you to histones and histone modifications and how they contribute to transcriptional regulation. It is an ideal starting point for those who are new to the subject or professionals in other fields needing a quick primer.
Contents:
0:35 Defining the epigenetic memory of gene expression
2:37 Chromatin and histones
7:12 Histone modifications
7:59 Histone acetylation and reading by bromodomain proteins
12:02 Histone methylation and reading by chromodomain proteins
19:17 The complex language of histone modifications
21:53 How a core set of marks help define chromatin states

Fabulous! I haven't paid attention to epigenetic advancements in a decade or more, and am amazed at how much more has been discovered. The complexity blows me away!!
I must complement you because you were much, much thorough in explaining a wider array of terms and processes than other Epigenetic tutorials do not cover. Congratulations for being so illuminating in such a vast and complicated discipline!
Thanks for your kind feedback Aidari. Best wishes for your ongoing studies!
Dr Adam West. I'll remember this name. It is an amazing video. I just needed to get a little familiar with modification marks and I learned much more than I needed. Great Job and thanks
Thanks! Beatifull lecture. Really sad that you stopped making videos
Such a great video. Thank you so much.
Great visualizations, thanks!
This is an amazing video. Thank you for making it.
thank you. great lecture and you made it very easy to understand
For those of us with only one college course in organic chemistry this is by far the easiest to understand description of the incredibly complex process of histone modification. What I would really like to understand better is how and when are the enzymes which drive the histone modification created during embryo development and later during a typical sleep wake cycle when different proteins are made depending on the time of day.
Thanks David. These are good questions and are an active area of research in the field!
Lovely ❤thanks for the great lecture
Super useful lecture. Thanks so much for sharing!
You are very welcome Catalina. Glad you found it useful!
A marvellous class! The practice part was absolutely necessary for understanding this complex and dense theme.
Glad you found it helpful Leonardo!
Amazing video, thanks so much!
Glad you liked it!
Lucid and beautifully structured. As a neophyte I felt I learned a substantial amount of basic knowledge in a short time.
Thanks for your feedback. Glad it has helped you move forward
Very insightful. You are doing great job :--)
very insightful. Thank You :-)
Thank you! It is very well explained complext topic
Excellent video, thank you
You're welcome John. Best wishes
This is so good. Thank you very much.
You're very welcome!
This was such a helpful video! Thank you! I would love to see a similar one about the Polycomb group and maybe a review on the techniques for epigenome analysis!
Glad you found it helpful Anita. Good suggestions
Great video. Thanks a lot!
Glad it helped!
Extremely good presentation!!!
Glad you liked it!
Super. Thank you!
Glad you found it useful Elisabeth
It was definitely a very good and enlightening lecture
Glad you found it helpful!
Thanks! Very informative :D I would love an ChIP-Seq/ATAC-Seq vídeo :D
Good idea! Are you more interested in what these techniques are and interpreting figures using them? or do you want advice on carrying them out and doing the bioinformatic analysis?
@@GenomicsGurus actually both of them are great ideas!! 🥰
Greetings from Bulgaria
Thank you
Glad it was helpful!
Thankyou
