Immunofluorescence Microscopy

Immunofluorescence Microscopy

A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

Chromosomal Theory of Inheritance

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Chromosome Structure

Chromosome Structure

A functional eukaryotic chromosome must contain three elements: a centromere, telomeres, and numerous origins of replication.
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
Telomeres consist of non-coding repetitive nucleotide...

Lampbrush Chromosomes

Lampbrush Chromosomes

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Polytene Chromosomes

Polytene Chromosomes

Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Chromosome Replication

Chromosome Replication

Before a cell can divide, it must accurately replicate all of its chromosomes, including the DNA and its associated histone and non-histone proteins. This process begins at numerous origins of replication during the S phase of the cell cycle in each of a cell’s chromosomes simultaneously. Certain nucleotides can act as origins of replication, but these sequences are not well defined - especially in complex, multi-cellular, eukaryotic species. The length of DNA that spans an origin...

Sus antecedentes:

La inestabilidad cromosómica (CIN) implica una segregación cromosómica errónea continua, que conduce a aneuploidía y es prevalente en la mayoría de los cánceres.
La CIN surge de factores intrínsecos como la disfunción del punto de control mitótico y factores extrínsecos como la radiación, influyendo en la progresión tumoral.
La formación de micronúcleos debida a la CIN puede activar respuestas inmunitarias a través de la vía cGAS-STING.

Objetivo del estudio:

Presentar un método sencillo para cuantificar y caracterizar la inestabilidad cromosómica (CIN) y los micronúcleos.
Proporcionar una técnica aplicable a líneas celulares y tejidos humanos y murinos para el análisis de la CIN.

Principales métodos:

Se empleó microscopía de inmunofluorescencia para visualizar y cuantificar la CIN y los micronúcleos.
El método se centra en técnicas sencillas y aplicables para el análisis celular y de tejidos.

Principales resultados:

El estudio detalla un método para cuantificar los eventos de segregación cromosómica errónea y la formación de micronúcleos.
La técnica descrita es adaptable a diversos tipos de células y tejidos.

Conclusiones:

El método desarrollado ofrece un enfoque sencillo para estudiar la CIN y los micronúcleos.
Esta técnica puede apoyar la investigación sobre el papel de la CIN en el cáncer y las respuestas inmunitarias, informando potencialmente sobre estrategias terapéuticas.
