  2. Tetracycline-controlled transcriptional activation - Wikipedia

    en.wikipedia.org/wiki/Tetracycline-controlled...

    The Tet-On Advanced transactivator (also known as rtTA2 S-M2) is an alternative version of Tet-On that shows reduced basal expression, and functions at a 10-fold lower Dox concentration than Tet-Off. In addition, its expression is considered to be more stable in eukaryotic cells due to being human codon optimized and utilizing three minimal ...

  3. Transactivation - Wikipedia

    en.wikipedia.org/wiki/Transactivation

    The transactivator gene expresses a transcription factor that binds to specific promoter region of DNA. By binding to the promoter region of a gene, the transcription factor causes that gene to be expressed. The expression of one transactivator gene can activate multiple genes, as long as they have the same, specific promoter region attached.

  4. Telomerase reverse transcriptase - Wikipedia

    en.wikipedia.org/wiki/Telomerase_reverse...

    Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most important unit of the telomerase complex. [5] [6] Telomerases are part of a distinct subgroup of RNA-dependent polymerases.

    Ras gene can be combined with rtTA (reverse tetracycline transactivator) to generate bi-transgenic inducible mouse model through tetracycline-controlled transcriptional activation e.g. mice carrying TetO-KrasG12D (TOR) and MMTV-rtTA (MTB), comes with the transgene expressing the reverse tetracycline transactivator (rtTA) in mammary epithelial ...

  6. Reverse transcriptase - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcriptase

    A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV, COVID-19, and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes.

  7. TET enzymes - Wikipedia

    en.wikipedia.org/wiki/TET_enzymes

    The TET enzymes are a family of ten-eleven translocation (TET) methylcytosine dioxygenases. They are instrumental in DNA demethylation . 5-Methylcytosine (see first Figure) is a methylated form of the DNA base cytosine (C) that often regulates gene transcription and has several other functions in the genome.

    Perhaps you've also heard the term "reverse racism" in the media, on Instagram, at work or in pockets of mostly white communities in recent weeks. Before understanding the concept of "reverse ...

  9. Two-hybrid screening - Wikipedia

    en.wikipedia.org/wiki/Two-hybrid_screening

    The Escherichia coli-derived Tet-R repressor can be used in line with a conventional reporter gene and can be controlled by tetracycline or doxicycline (Tet-R inhibitors). Thus the expression of Tet-R is controlled by the standard two-hybrid system but the Tet-R in turn controls (represses) the expression of a previously mentioned reporter such ...
