Some stats and facts about the #Takifugu#rubripes assembly by @genomeark: this is the third iteration of the assembly. The first was completed in 2002. There was another iteration done in 2011. Why was the pufferfish sequenced so early? A lot has got to do with Sydney Brenner...
Indeed, as we can see in this archived version of @ensembl, the Fugu genome was the 5th vertebrate genome to be completed, after human/mouse/rat and zebrafish. Even though zebrafish is widely used as a model organism, Sydney Brenner argued that Fugu was worth sequencing ...
... The reason is that Sydney Brenner was passionate (obsessed?) with gene duplications and functional diversification. I.e. a gene duplicates in two copies, and over time, each copy can specialize in doing something slightly different. ...
#JPM2021@TwistBioscience My Highlights: back to the #DNAWrite field. TwistBio chip: 1M oligos but only as centralised factory setting.
Expanding to a new factory in Portland (roadmap 2022) to reduce TAT. Also mentioned the "long tail" of Clonal Ready Gene Fragments.
They have a few slides on #DNAasStorage with a denser chip in prototype phase where they think they can archive 1Tb for $100 (pay once, archive forever*) which, if my calculations are correct, would allow for 10-12 years of @awscloud Deep Glacier or similar mth/GB=0.00099*12*1E3
#JPM2021#LiquidBiopsy notable by their absence, which is more than excusable in these pandemic times: @freenome, Biocartis, Biodesix, Epic Sciences, ArcherDx (not by this name anyway). Worth following developments for them. In my book, worth following #Freenome of the ones here.
Smaller #LiquidBiopsy#Oncology#Diagnostics players also not at #JPM2021 but important in the field: Personalis, Inivata, Exosome Diagnostics, Epigenomics Ag, Personal Genome Diagnostics, Foundation Medicine, Singlera, Cambridge Epigenetix, and Bluestar Genomics.
Their T-Detect method is aiming at #MRD monitoring, here shown in a slide that relates it to their ImmunoSEQ T-MAP Cancer mapping tool, and their Identification of clinical TCR candidates.
They stress the T-cell Diagnostics angle in different slides. I recall only @freenome explicitly mentioning immune-profiling from the group of companies in early cancer diagnostics and #epigenomics profiling (Grail/GH/Thrive/Freenome/BioStar/CEGX/etc.)
#JPM2021@carisls My Highlights: in the #CancerDiagnostics area, they position themselves favorably wrt Foundation medicine, Tempus, and Personalis (haven't heard of NEO before).
They put #LiquidBiopsy at the end of this trajectory slide: (couldn't see any years in milestones for this)
No indication that #Caris are pursuing #Epigenomics profiling of #LiquidBiopsy: they mention exome and transcriptome in their slides.
