Self-amplifying mRNA Vaccine (SAM) RNA vaccines can be divided into traditional mRNA-based vaccines and self-amplifying mRNA (SAM) vaccines. Their basic principle is to use the host cell's transcription system to produce target antigens to stimulate adaptive immunity. The difference is that the former contains only the target antigen gene and cannot replicate itself; the latter encodes the engineered genome of the RNA virus, which contains the virus's non-structural protein gene and the. Synergistic Activation Mediator (SAM) Description. SAM uses specially engineered sgRNAs to increase transcription. This is done through creating a dCas9/VP64 fusion protein engineered with aptamers that bind to MS2 proteins. These MS2 proteins then recruit additional activation domains (HS1 and p65). Performanc

SAM: a strategy for gene activation. The dCas9 is fused to VP64 and the sgRNA has been modified to contain two MS2 RNA aptamers to recruit the MS2 bacteriophage coat protein (MCP), which was fused to the transcriptional activators p65 and heat shock factor 1 (HSF1).

Aside from restriction modification systems, DNA methylation also plays an integral role in regulating genome replication, repairing mismatched basepairs or small indels that occur during DNA synthesis, and protomoting or repressing protein expression. Methylases involved with these processes (for example Dam and Dcm methylases) are independent. Sam was born and raised in Lancaster, PA. He earned his B.A. in biochemistry from Columbia University in 2007, where he trained with Professor Ruben Gonzalez, and his Ph.D. in chemistry from the University of California, Berkeley in 2014, under the mentorship of Professor Jennifer Doudna.

This separate, MS2-mediated, transactivation complex significantly enhances the efficiency of TGA for dCas9-VP64. However, the dCas9-VP64 construct still exceeds the capacity of regular AAVs. To solve this issue. SAM takes advantage of the specificity and ease of reprogramming of Cas9 nucleases, which are targeted to a specific locus in the endogenous genome by guide RNA.
