Published on: July 27, 2016
Resumen
El gen HuBlym-1 es el gen HuBlym-1.
Área de la Ciencia:
- La oncogénesis es la oncogénesis.
- Biología Molecular Biología Molecular
- Genética del cáncer Genética del cáncer.
Sus antecedentes:
- Se sabe que el gen HuBlym-1, implicado en el linfoma de Burkitt, induce focos celulares en la transfección celular NIH 3T3.
- La activación de proto-oncogenes a menudo implica cambios mutacionales, lo que lleva a la formación de oncogenes.
Objetivo del estudio:
- Investigar si las alteraciones de secuencia en el gen HuBlym-1 contribuyen a su actividad transformadora en el linfoma de Burkitt.
- Para determinar si el aumento de la transcripción del gen HuBlym-1 explica su potencial oncogénico.
Principales métodos:
- Secuenciación de ADN de clones recombinantes de las líneas celulares de linfoma de Burkitt.
- Análisis de los niveles de transcripción del gen HuBlym-1 en las líneas celulares de linfoma de Burkitt.
- Ensayos de formación de foco celular después de la transfección celular NIH 3T3.
Principales resultados:
- No se encontraron diferencias de secuencia entre los clones de HuBlym-1 del linfoma de Burkitt y la secuencia reportada.
- No se observó un aumento significativo en la transcripción del gen HuBlym-1 en las líneas celulares de linfoma de Burkitt.
- Se secuenciaron clones de ADN recombinante que se hibridaron cruzados con HuBlym-1 pero no indujeron focos.
Conclusiones:
- La actividad transformadora del gen HuBlym-1 en el linfoma de Burkitt no se debe a mutaciones en la secuencia.
- El aumento de la transcripción génica no explica el potencial oncogénico de HuBlym-1.
- El mecanismo de activación del gen HuBlym-1 en el linfoma de Burkitt sigue siendo indeterminado.

Histone Modification
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
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 9th...

Activation and Inactivation of G Proteins
Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...

Transducer Mechanism: Enzyme-Linked Receptors
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
