Resumen
La sangre entera y los hisopos bucales muestran promesa como tejidos sustitutos para estudiar la metilación del ADN en la investigación de la espina bífida cuando el tejido dural no está disponible. Este hallazgo ayuda en futuros estudios epigenéticos sobre defectos del tubo neural.
Área de la Ciencia:
- Epigenética
- Genética Humana
- Biología del Desarrollo
Sus antecedentes:
- Los defectos del tubo neural, como la espina bífida, están influenciados por mecanismos epigenéticos como la metilación del ADN.
- Existen estudios limitados en humanos sobre perfiles de metilación del ADN en tejido del sistema nervioso afectado por espina bífida.
Objetivo del estudio:
- Evaluar los perfiles de metilación del ADN en el tejido dural de lactantes con espina bífida.
- Evaluar la sangre entera y los hisopos bucales como posibles tejidos sustitutos para el análisis de metilación del ADN en la investigación de la espina bífida.
Principales métodos:
- Se midió la metilación del ADN en tejido dural, sangre entera y hisopos bucales de 27 lactantes con espina bífida.
- Se utilizó el chip de perlas Illumina Infinium MethylationEPIC para el perfilado de metilación del ADN.
Principales resultados:
- Se encontraron correlaciones significativas entre la metilación del ADN en el tejido dural y tanto la sangre entera (1555 asociaciones) como los hisopos bucales (920 asociaciones).
- Un porcentaje sustancial de sitios CpG no mostró una metilación diferencial significativa entre el tejido dural y la sangre entera (33%) o los hisopos bucales (27%) después del ajuste de FDR.
Conclusiones:
- La sangre entera y los hisopos bucales pueden servir como sustitutos viables del tejido dural en estudios de metilación del ADN cuando el tejido dural es inaccesible.
- Se necesita más investigación con cohortes más grandes para validar estos hallazgos y explorar factores epigenéticos en la etiología de los defectos del tubo neural.

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Plant Cells and Tissues
65.8K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Tissue Membranes

A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Different tissues work together to perform a unique function and form an organ. Organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system and a root system. The shoot system consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant,...
