They express 9,000 genes differently than their cells than than the cells in their normal position. So massively remodeling their uh their transcriptto towards their new lifestyle.

sRNAs that repress transcription have been engineered to create orthogonal and composable regulators that can be used to construct RNA-only transcriptional networks
Diagram of immunoprecipitation (IP) using either pre-immobilized or free antibodies.
Immunoprecipitation is a technique for the isolation of protein or a complex (protein-protein interactions) Sample is combined with a specific antibody for the epitope of interest. The antibody-protein complex is removed and analysed.
Co-immunoprecipitation (can isolate one type of protein in its complex)
Isolate POI(s) Good with low conc. of POI Protein interactions Unknown proteins Determine if protein is actually being expressed in a given tissue.
Western blot is carried out to analyse the output.
Vary salt and detergent levels to preserve or destroy protein interactions.
GenExpDB is the world’s largest repository for E. coli gene expression data. This site is a widely used public resource for gene expression analysis.
The basal level of T7-dependent tran-scription in this strain can be reduced by constitutive produc-tion of T7 lyzozyme, a natural inhibitor of T7 RNAP, usingplasmids pLysS and pLysE
expression is tightly regulated
cumate inducible
genetic devices have been designed for suppressing leaky basal expression levels through the engineering of super‐repressors (Ruegg et al, 2018), exploitation of antisense RNAs (O'Connor & Timmis, 1987), or physical decoupling of regulatory elements along with conditional proteolysis
the leakiness and inducibility of the ligand-inducible LacI repressor mutants have been quantified and classified
Consequently, the plasmid donor cells do not express gfp
Does the leaky expression not hinder the detecting and quantification of transconjugants in epifluorescence microscopy?
We have demonstrated that small RNAs can tightly repress their target genes when their synthesis rate is smaller than some threshold, but have little or no effect when the synthesis rate is much larger than that threshold
In particular, small RNAs are shown to establish a threshold for the expression of their target, providing safety mechanism against random fluctuations and transient signals. The threshold level is set by the transcription rate of the small RNA and can thus be modulated dynamically to reflect changing environmental conditions.
in the absence of tamoxifen, it exhibits some activity
strong promoters capable of driving expression of microbial opsins or fluorescent proteins in specific populations can exhibit leaky expression elsewhere. This low-level leak may be virtually undetectable as light responsiveness or fluorescence but can be a serious issue when expressing Cre recombinase.
it can be useful for reducing leaky expression of toxic proteins
antisense transcription
We report the construction of a family of vectors that contain a reengineered lacIq-lac promoter-operator complex in which cloned genes are strongly repressed in the absence of inducer.
While these techniques offer good repression, they exhibit leakiness that precludes the gene of interest from being completely turned off

Massive mining of publicly available RNA-seq data from human and mouse
repeat expansion at IIL1 leads to increased accumulation of 24-nt siRNAs in a temperature-dependent manner that correlates with the iil phenotype. We show that DCL3 and other components of the RNA-dependent DNA methylation (RdDM) pathway are essential for this siRNA-directed epigenetic gene silencing
