Resumen

Las grandes deleciones únicas en humanos (hDels) impactan la proliferación celular y la expresión génica. Este estudio revela sus roles moleculares y celulares, destacando efectos específicos en el cerebro para dos deleciones clave.

Sus antecedentes:

Las secuencias funcionales se pierden durante la evolución molecular.
Existen miles de deleciones específicas de humanos (hDels).
Se desconoce el impacto de las hDels grandes (≥50 pares de bases) en los procesos celulares.

Conclusiones:

Las secuencias perdidas durante la evolución humana tienen funciones moleculares y celulares significativas.
Las hDels grandes desempeñan un papel en la regulación de la expresión génica y los procesos celulares, incluidos los efectos específicos de los tejidos en el cerebro.
Desarrollado un marco robusto de cribado CRISPRi para la interrogación funcional de variantes genéticas específicas de humanos.

Cis-regulatory Sequences

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Master Transcription Regulators

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Conservative Site-specific Recombination and Phase Variation

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...
