Mitochondria are essential to our overall health and well-being. In addition to producing energy, they regulate many critical processes in the body. (1/11) #mitochondria #energy #health
Mitochondria play a key role in the production and regulation of neurotransmitters. They also help produce key hormones like cortisol, estrogen, and testosterone. (2/11) #mitochondria #hormones #neurotransmitters #neurotwitter
Mitochondria are involved in epigenetics, which is the expression of #genes from the nucleus. They send signals to the nucleus that turn genes on or off. (3/11) #epigenetics #genes #mitochondria

Two’s Two’s Two’s - Excited to share our study finding evidence of 2 major subtypes of obesity. Hope these can eventually help support more accurate understanding, diagnosis & treatment of #obesity and #diabetes. go.nature.com/3eNJF1s
Two patterns of Twin discordance – All started with data-driven finding of 2 major patterns of MZ twin discordance using a dimensional reduction approach. Thank you @TwinsUKres for pioneering cohort and generosity of your staff, funders and participants! nature.com/articles/s4225…
The discordance patterns suggest two forms of human phenotypic plasticity. Type-A = adipose only | Type B = adipose, lean mass, and #insulin co-discordance. Interestingly, Type B shows far more #epigenetics differences suggesting developmental programming.
My last live session (still tons of on demand to go)! We'll be looking at the role of #nutrition and #epigenetics in health and disease. #Nutrition2022 #NutritionLiveOnline
Starting the talks with some unpublished work from USDA and Baylor. #Nutrition2022 #NutritionLiveOnline
What is epigenetics? It's alterations of the genome that support or silence gene expression. #Nutrition2022 #NutritionLiveOnline

Picking up where @rita_rebollo left, we spent a couple of years annotating and analyzing the rest of the rice #weevil #genome (ok, the 15% left after removing repeats)! All info presented here is on the huge Additional file 2 in @BMCBiology doi.org/10.1186/s12915… 1/n
@VargasChavezC and @gabaldonlab performed a comprehensive #phylogenomic analysis of the rice #weevil and found that this insect has a high gene expansion rate when compared to other beetles. 2/n
With the invaluable help of the SymT group from @INRAE_UMR_BF2I we have also reconstructed the #metabolic pathways from both #symbiotic partners. Specific losses of enzymes in the #weevil genome are limited while its #endosymbiont has suffered much more degradation. 3/n
1/ Epigenetics means on top of genetics. The study of Genetics is all about the DNA. Its about how its structured and packaged. Epigenetics is about how Genes are expressed and regulated.
2/ We are born with our Genetics, but our Epigenetics is acquired by experiences and environmental exposure. I don't want to get too deep into epigenetics, but I think there are a few concepts that are important to understand.
As short-read #sequencing (SRS) costs begin to drop again, undoubtedly fueled by a resurgence in competition, I suspect many liquid biopsy providers will add blood-based whole-genome sequencing (WGS) to supplement, or replace, the deep targeted sequencing paradigm.
With a few exceptions, most clinical-stage diagnostic companies build patient-specific panels by sequencing the solid tumor, then downselecting to a few dozen mutations to survey in the bloodstream.
I don't think this approach is going anywhere anytime soon.
I don't think this approach is going anywhere anytime soon.
However useful, this deep-sequencing approach suffers from several challenges:
1. It requires access to tissue.
2. It requires the construction of patient-specific PCR panels.
3. It requires significant over-sequencing ($$$).
4. It introduces a third layer of error (PCR).

It is very important in this period of humanity to take a serious look at what is happening in the world friends.

#Menticide is here & with it, a new attempt to establish a "#TechnoTotalitarian" rule over the lives of American citizens.
The final variant of #Coronavirus could very well be the manifestation of a #NewWorldOrder under #totalitarian rule.

That may sound absurd, but what is very concerning is that many talking heads in the media & even public figures are now making very carefully worded emotional appeals to logic to further induce a totalitarian #masspsychosis.

I reviewed quite a few reproductive #epigenetics papers over the last several years and I find myself saying the same things over and over. So a thread 🧵 on things to consider and important information to include in your manuscript 1/

What your are thinking right now is having an impact on your genetic expression and in turn your health. What you are feeling right now is having an impact on your genetic expression and in turn your health.
What emotion you are going through right now is having and impact on your genetic expression and in turn your health.
Your thoughts, feelings and emotions impact your biology! If your emotions can bring such a physical and mental change in you, you now know how it’s impacting your genes at a cellular level too! When they say genetic most people give up like there is nothing to do.
Proud to share our new paper!! We explored recent evidence on #epigenetics #transposons and #population #genetics to look beyond the two-speed genome evolution model!! @OggenfussUrsula @danielcroll @MFSeidl sciencedirect.com/science/articl…
Genomic compartments specifically benefit plant pathogen lifestyle? Well... genomic compartments occur all across the tree of life @OggenfussUrsula @MFSeidl @danielcroll
Then, they are a consequence of #transposon insertions and accumulation? Or a consequence of #chromatin organization? Probably both! @OggenfussUrsula @danielcroll @MFSeidl
So many people are curious about their genes. These same people might get curious about their “true biological age” and companies are happy to take their money. I just wrote about it. Here’s what I found. THREAD.
23andMe has become the “Kleenex” of the direct-to-consumer genetic testing world. It’s short-hand for the type of product itself. You spit and get back a report about your genetic risk for cardiovascular disease, for hating the taste of cilantro and for having a unibrow.
But there’s a new tide rising: direct-to-consumer EPIGENETIC kits. Already a few companies are offering these very expensive saliva/blood/urine kits ($300-700 US) to give you tailored reports on how your body is truly aging and what to do about it.

2/ Treg cells are known to require a lineage-specific DNA hypomethylation pattern during development that stabilizes their lineage. We wanted to determine whether maintenance DNA methylation is required for Treg cell lineage development and stability.
3/ Accordingly, we bred mice with Treg cell-specific deficiency in the epigenetic regulator Uhrf1, which maintains methyl-DNA marks. These mice displayed a profound inflammatory phenotype.
Today we launch the @ECHO_ERCproject online!🥳

A couple of historical inaccuracies to start. Waddington was saying the opposite – cell fate (the cellular event in epigenesis) is probabilistic, not deterministic. The major point he was making was that genes have a role in influencing epigenesis, a major argument at the time
Waddington did not ignore environment at all. In fact, he treated Drosophila larvae with heat/ether to see whether he could influence cell fate. He considered the epigenetic landscape (cell fate) potentially modifiable by environment and genetic variation, see next image
I wasn’t really expecting this tweet to get such a response. It clearly hit a communal nerve. Probably in part because I was deliberately provocative 1/
2/ Did @ryanlisterlab really show that DNA methylation has no role in transcriptional repression? Of course not. But they do show that it does not seem to be enough by itself to change the expression of genes
3/ Why is that observation important? Because it makes us think a bit more critically about something that plagues #epigenome-wide association studies, the idea that environment changes DNA methylation, gene expression and cellular memory.
