This is a thread about how anyone can use publicly accessible sequence databases and free software to discover new things about #genomes, #biology, and life on earth.

Genomes are absolutely loaded with complex information, most of which we still don’t understand.

Complete and near complete genome sequences are now available for many organisms.

However, decoding the information in these genomes remains a slow and difficult process. Image
A large proportion of most published genome sequences consist of DNA that is incompletely understood in terms of its evolutionary origins and functional significance. Image

$NTLA and $REGN report initial data from ph1 study of #ATTR for NTLA-2001. All patients across the two doses showed 92-94% TTR reduction at day 28.
#crispr #genomics #genetherapy #biology #biotech
At both dose levels, $NTLA-2001 was generally well tolerated. 2 patients reported transient infusion reactions, which was the only observed treatment-related adverse event.
$NTLA-2001 is an in-vivo administered #genetherapy.
It is one of the first few in-vivo #GeneTherapy being tested. Congrats to the $NTLA and $REGN teams.

I have found only a handful of reports in literature of

A LinkedIn post by Sarah Hartley-Kane on the UK becoming the 'Silicon Valley of Global Genomics'… Image
The cost of a whole genome is probably already in the $100 mark, but not widely available: the only companies that have shown realistic goals towards the $100 genome are: MGI Tech with their DNBSEQ-T7 and T10x4 large instruments, together with @UltimaGenomics with their U100 ... Image
which is expected to be commercially available in 2023 and produces $1/Gb reads (albeit short-reads with homopolymer noise), and $ONT.L Oxford @nanopore, which is currently closing into the $2/Gb mark of Q20+ single pass reads on the PromethION flowcells Image

It’s another Thursday, and that means it’s time for another #tweetorial! Today, we want to show you how you can view RefSeq #annotations on Ensembl 🥳

#bioinf #genomics #assembly #EnsemblTraining
While Ensembl gene models are annotated directly on the reference genome, #RefSeq are annotated on mRNA sequences. In other words: genome browsers will have different annotation methods, so you might be interested in comparing these annotations side-by-side 📖🤔
👂🏽You say you want to make direct comparisons of annotations between @NCBI’s RefSeq and Ensembl? Now is your time to try it out on Ensembl! 🏃🏽

Major update for small cell #lung cancer! #LCSM

With @juliensage + @FoundationATCG, our paper now on @bioRxiv:

►Genomic analysis of *3,600* pts with SCLC; largest SCLC study to date!

►Multiple interesting findings discussed in this 🧵…
This study is unique in many ways:

> The #SCLC cohort studied came mostly from community sites --> representing a more typical “real-world” cohort of SCLC.
> The genomic data are tied to clinical data + outcomes.

To the best of our knowledge, our study analyzes the largest number of SCLC tumors from African ancestry to date:
> n=256 AFR cases
> 7.1% of the entire cohort
#Diversity in clinical studies is critical!!

Our many-years-in-the-making EpiC Dog epigenome paper is finally out as preprint @biorxivpreprint
Close collaboration with our lab's lead bioinformatician @new__hong & MBD-seq aficionado @MethylAReum, spearheaded by our versatile PI @je_yoel @SNUnow #Epigenome #Genomics #Dog A🧵
While still in early stage format, EpiC Dog is a culmination of our efforts to annotate functional elements of dog genome enabled by chromatin states discovery and profiling super-enhancer and DNA methylome landscapes across multiple tissue types. See also BarkBase and DoGA /2
Modern dogs are champions of modern genetics. They empower us with their evolution and diversification of phenotypic traits from morphology to behavior. One reason dog genomics has become >popular compared to genomic studies of other domesticated mammals, but who's comparing? /3

Looking at a little Strategy: 🧵

I hope putting out my game plan will help other get ideas on how to do a strategy for investing to maximize returns.
1/ I am finally getting comfortable with my strategy. I have a set amount now that I am contributing to each of my portfolios for #biotech, #tech and #crypto. My plan is to use the any rallies to fade some of the companies I want get rid of that disappointed me.
2/ Then I want to use that cash to accumulate more of the companies I like. The max tax loss I can take for a year about $3,000. That would reduce my taxes and get me back about 25% or $750 in tax savings. It will work out like getting some cash back on those losers.

Yesterday, I completed my months-long quest to accurately identify all sci-fields emerging in WW other than the well-established Neuro ⬇️
For, it's been long since we noticed emerging scientific tangents that span diverse fields like: #ML, #Materials_Science, #Pharmacology, #Genomics, #Open_Hardware, etc
Awesome -- But, how does one possibly map all these frontiers without employing actual people to read and annotate dozens of hundreds of abstracts at a time?

Want to apply #deeplearning in your #regulatory #genomics analyses but overwhelmed by suite of interpretation tools? Check out ExplaiNN: interpretable and transparent neural networks for genomics with @NovakovskyG @ofornes @sara_mostafavi @WyWyWa 🧵👇…
ExplaiNN is an adaptation of NAMs from @agarwl_ & team for genomic sequences - predictions are a linear combination of independent CNNs- each consisting of 1 conv. layer with a single filter and two FC layers. This seemingly simple approach performs similar to multi-layer CNNs1/6
It provides importance of discovered motifs by mere visualisation of weights of the output layer. No need for filter nullification or clustering of importance scores from attribution methods! ExplaiNN on ATAC-seq of mouse immune system recapitulates results of AITAC model 2/6

1/As promised & after reading $NTLA latest Q1 2022 financial report here is my analysis regarding @intelliatx latest corporate status. I have focused only on the main issues that I found to be the most interesting & relevant. #CRISPR #GeneEditing #BioTech #FinTwit #Genomics👇
2/NTLA-2001 is the most advanced In-Vivo #CRISPR/#Cas9 #GeneEditing program in $NTLA portfolio & is aimed to treat Transthyretin Amyloidosis - (ATTR). NTLA-2001 could potentially halt & reverse the disease in a “one time” treatment by knocking out the TTR gene with a single dose
3/In February $NTLA has presented an updated clinical data from its Phase 1 study of NTLA-2001 which included 15 patients with ATTR amyloidosis. IMO NTLA-2001 readout looks promising & here is a summary that I wrote shortly after @intelliatx’s presentation of NTLA-2001👇

1/ I have been spending a lot of time with the market selling off trying to share and teach about investing and how to build a portfolio to diversify across assets and risks.
2/ I think its good to take time when the market is down to focus on improving our game for the next time around. Since I am a biotech focused investor, I would like to share with you the trends within the biotech space I think could propel the next decade of innovation.
3/ If you know me already, these won't be very new to you. My first big concept is using tech in biotech with developing #AI, #ML and #Automation to drive down the costs and improve the success of clinical development.
