Among other treats in these expression vectors are the SV40 mammalian promoter and a high copy origin of replication (pUC) for bacterial amplification of these plasmids.
The Biodistribution studies covered by @Jikkyleaks show LNPs getting into the intestines.
Its estimated that each shot contains billions of these plasmids and if they get into the gut microbiome, they can replicate to 50-300 copies per cell.
If any vaccinated patient is then placed on Neomycin or Kanamycin, these will be the only bacteria that survive
As these plasmid encode Kan and Neo resistance. Its not known if these contaminating plasmid can also express spike protein but some of the vectors have T7 tails so we cant rule that out.
What happens if we inject billions of Antibiotic resistance genes into billions of people?
What happens when the injection contains LNPs that can get to your intestines and transform bacteria with these genes?
Why isn't there sequencing QC of every lot given how cheap this is to perform in 2023?
Why QC things when gov is paying & you have a hall pass and a mandate?
There are several stones left unturned in the data as I didn’t want to hold up disclosure of this.
1)do the paired end reads imply linear or circular DNA?
2)what is the strandedness count? Directional libraries should be able to answer this. Might inform if the vector sequence is DNA or RNA or both.
3) the EMA has limits on the dsRNA and they measure this with some ELISA assay which I’m suspect of?
4)error rates in the vector sequence should be lower than in the mRNA as the mRNA goes through a T7 polymerase step with PseudoU and an RT step with PseudoU. There is no PseudoU in the vector.
5)the SV40 in this vector is just a strong promoter. It is not the entire SV40 genome.
Is the plasmid sequence DNA or RNA?
DNA will provide sequence from both the watson (antisense) and crick (sense) strands.
Download the BAM files and run these 2 samtools scripts on it. This will count the Forward and Reverse strands in the data per base across the contig.
Now put those in excel and subtract the Forward read count from the reverse read count and chart the results.
What do we see? We see a foward strand bias for half the vector and then a sudden shift to a reverse strand bias at position ~2100
Thats the exact location of the T7 promoter which initiates synthesis of the mRNA.
This is hard evidence of the vector sequence being DNA and and not an RNA mirage.
The variability in the strandedness in the mRNA region is very interesting? Maybe G4s or other RNA knots?
T7 Promoters are notoriously leaky in E.coli. You dont need T7 bacteriophage around to get expression.
Someone in the recent spaces I was on raised a good question. references welcome.
What is the differential transformation efficiency of LNPs on mammalians vs bacterial cells. They are designed for membranes.
But you only need 1 in billion to hit and if there is selection there, the plasmid takes off. E.coli doubling time is 30 minutes. We need clinical verification with qPCR for the vector/insert.
Also temperature and environment play a big role in E.coli transformation efficiency. You can find strains that transform at 37C. Add in patient fevers and even naked DNA with no LNPs will transform the bacteria. Important topic raised. It was VSRF space zymoresearch.com/products/mix-a…
That slope in the stranded chart was bugging me. Fixed the bug. Better depiction here. DNA should sense and antisense reads. mRNA only sense strands. SO when you substract Antisense from Sense across the vector you see the T7 promoter at base 2200. The other chatter might be..
RNA fragmentation bias or Pseudouridine pause sites.

when people drag out this bromide, it’s a sign they are parroting their echo chamber and have never read the literature on PCR. Everyone in clinical Dx knows of viability PCR

Where does one actually find the Sequence for the Bivalent vaccines being administered these days?
I don't see it in NCBI.
I don't see it in the NEJM paper/supp.
I don't see it in the clinicaltrials.gov site for mRNA1273.214 nejm.org/doi/suppl/10.1…
Just to clear the smoke.
There is a thread I was blocked on attempting to clarify a claim that a trial that showed poor results from 300mg CBD taken orally for SARs could be used to suggest it worsened EVALI.
Oral CBD administration is hepatic portal. Its metabolized.
Vapes are not.
THC vapes are usually 60% THC/THCA and 1-2% CBD.
5mg gummy is a standard THC oral dose. 300mg CBD is about 1/5th -1/10th of what is used in epilepsy and what in vitro models of RdRp pol inhibition by CBD.
For someone to get to 300mg of CBD from vape pens they would need ~4200 Hits/day. This would deliver 17,000mg of THC in the process.
AND
It bypasses the hepatic portal system.
So this is a very sloppy way to claim CBD from the pens might exacerbate EVALI.
Hop Latent Viroid is devastating the cannabis industry.
To help sort out its pathology,
We sequenced infected and non infected leaves (in duplicate) polyA transcriptomes.
100M reads later and we have some interesting findings.
27K Differentially expressed genes
We published a preprint describing 25 genes we thought would be down regulated based on their homology to the viroids genome sequence.
The Expansin gene was one of them and indeed demonstrates reduced expression in the infected plants (top 2 tracks).
This validates the assumption that HpLVd exerts its pathology through RNA interference of genes with similar sequence to the Viroid circular RNA genome.
