Barbara McClintock is a true inspiration for all scientists and especially as a woman in science a superhero! Her insights and predictions about transposable elements are incredibly accurate and keep feeding our research to date
#TransposonDay2023
Excited to have played a small part in the recent paper by
@CarrollDonal
lab which identifies SPOCD1 required for human male fertility and
#transposon
silencing. C19ORF84 binds SPOCD1 and thereby bridges the piRNA and methylation machineries in vivo
Maybe it's just me but although I see the benefits in virtual conferences, I think poster presentation is getting even less attention than in "in person" conferences.

Have a look at my recent talk at the

community meeting if you are interested in studying
#transposable
elements at unique loci in single cells using long reads. It was great fun taking part in the meeting with loads of new advances in long-read sequencing!
@rberrens
investigated TE expression at unique loci with CELLO-seq. Currently 'problems reside with unambiguous mapping of short cDNA reads' whereas, with long reads 'we were able to get full-length transcripts’ & 'have less bias than the short-read data’
It is great to be finally able to share our research in the Berrens lab with everyone
@IdrmOxford
to be able to collaborate more and use this amazing setup of diverse researchers and harness their experiences for interdisciplinary science!
@RBerrens

Really cool study using
@nanopore
sequencing to find de novo
#transposon
insertions in drosophila somatic tissue finding that TE expression levels do not predict their mobility.
Very happy about the outcome of this fruitful collaboration with the
@CarrollDonal
lab. Here we identified SPOCD1 as a novel player linking MIWI2 to de novo methylation to control especially young
#transposons
-L1 and IAP - in foetal testis without the production of piRNAs.
Our new paper on piRNA-directed DNA methylation is out. We defined MIWI2’s interactome in foetal testis and identify SPOCD1 that links MIWI2 to the de novo methylation machinery.
More to come shortly!
Looking forward to present our new work on single cell long read RNA sequencing for

expression. Hope for some great discussions at the

It is very similar to our igem project from 2010. As a group of 20 undergraduates we came up with this project and made a Mirna based tuned knockdown called mituner and delivered with evolution optimised aav to specific cells in Vivo

Hello
@UniofOxford
friends! I know this is late notice but I’ll be giving a talk tomorrow Friday April 21st 3 pm
@IdrmOxford
, hosted by
@RBerrens
with happy hour to follow! 🍻
Today we are initiating the
#transposon
network meeting with 2 excellent speakers: Helen Rowe from

and Noah Kessler from
@GeneticsCam
. We will also have a small breakout session about "Epigenetics to tame TEs?". Department of Genetics Cambridge at 4pm in the Part II room.
Our latest work is out in

This exciting project was led by the very talented
@Sam2Ross

It is unfortunate if people cite the information of your paper wrong. CELLO-seq is only reliant on long read sequencing data and not a combination of short and long reads to study
#transposons
at unique loci. Let's keep the information of the literature intact

Fun facts of a
#WomanPI

#ManPI
- when you have a neutral lab name like

And here it is in print! So excited to see this finally out! If you missed this the first time, transpose on over to

Finally, read this really exciting preprint from

@AliciaOshlack
I personally don't like to apply for women only awards as I want to be seen as a scientist and in my opinion a women only award will just underline that women cannot compete with men in the awards so need a separate one which is the wrong message in my view.
Today is
#transposon
network meeting at 4pm in
@GeneticsCam
partII room. Monique Merchant will present on
#ERVs

@nanopore
single cell sequencing. Please join and bring change for beer and vine during discussion session. In need of

It's great that more people are thinking about methods how to properly quantify Line1 expression. Will need to look at this new method. Very important also with regard to

@BabrahamInst
It has been a long time that I emerged myself into the world of RNAs by attending
#RNA2020
. I was blown away by the breadth of research and leave this meeting with loads of food for thought! THANK YOU so much for sharing your work everyone!
@TChelmicki
and I are thrilled to share with you a novel means of retrotransposon control, specific to ERVKs. When 5mC DNA methylation fails, m6A RNA methylation can degrade activated ERVK mRNAs. 1/n
Great work by the
@PaulFlicek
's lab on "opposing contributions of LINE L1s and L2s to regulatory
evolution. [...] active LINEs do not generally arise from lineage-specific insertions, [...] predominant mechanisms for regulatory activation is mutation of ancient elements"
Our next TE network meeting will be on 17th of June at 4pm in the
#Genetics
department Part II room. We will have Marta Seczynska (Lehner Lab) and Cristian Riccio (Miska & Hemberg Lab) presenting. Discussion will be on:
"Which seq method do you use to study
#transposons
?"
Interested in piRNAs and transposon methylation? Our new paper introduces TEX15 as an interactor of MIWI2 and reveals an essential role in the execution of piRNA-directed DNA methylation.
Our next
#transposon
network Cambridge meeting is taking place today at 4pm
@GeneticsCam
. We have Yorgo Modis and Anna Protasio presenting and will have discussion with drinks and pizza kindly sponsored by NEB.

This is very cool, also a topic we got to during our iGEM project back in 2010 using miRNA binding sites called miTuner :) Really cool that someone else found this very important.
We know the importance of subtle gene dosage variation, and yet the main tool of molbio is gene KO/KD. In our new preprint,
@JuliaDiumenge
introduced subtle modulations of transcription factor dosage by CRISPRi/a, and quantified responses by scRNA-seq. 1/
