Resumen

Se exploraron los mecanismos que rigen la recombinación de cambio de clase de anticuerpos (CSR) específica de orientación. La configuración topológica del cambio, incluida la orientación de la transcripción y la distancia de la cromatina, dicta resultados productivos de CSR, salvaguardando la diversidad de anticuerpos.

Sus antecedentes:

La recombinación de cambio de clase de anticuerpos (CSR) genera diversos isotipos de anticuerpos al reemplazar los exones de la región constante Cμ con exones posteriores.
Los mecanismos que controlan la CSR productiva específica de orientación siguen siendo poco comprendidos.

Conclusiones:

Los mecanismos intrínsecos de la cromatina salvaguardan la CSR productiva específica de orientación a lo largo de la evolución.
La STC, que abarca la orientación transcripcional, la distancia de la cromatina y la organización del dominio, es un determinante clave de los resultados de la CSR productiva.

Heterochromatin

Heterochromatin

The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at...

Inheritance of Chromatin Structures

Inheritance of Chromatin Structures

Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Euchromatin

Euchromatin

The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions take up more dye, appearing darker, while the less-compact areas take up less dye and appear lighter. Based on the compaction level, chromatins are classified into two primary forms – euchromatin and heterochromatin.
Euchromatin is the less dense region of the chromatin and stains lighter. Euchromatin contains histone H3 extensively...

Chromatin Modification in iPS Cells

Chromatin Modification in iPS Cells

Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
