Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

What is Gene Expression?

What is Gene Expression?

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

What is Gene Expression?

What is Gene Expression?

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

Taping Over Different Ground Profiles

Taping Over Different Ground Profiles

Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Expressing Solution Concentration

Expressing Solution Concentration

A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
Concentrations may be quantitatively assessed using a wide variety of measurement units, each convenient for particular applications. Molarity (M) is a useful concentration unit for many applications in chemistry.

Cell Specific Gene Expression

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Sus antecedentes:

Los métodos actuales para detectar ARN glicosilados (glicoARN), como el marcado metabólico y la oxidación con periodato optimizada para ARN y marcado con aldehído (rPAL), tienen limitaciones.
Existe la necesidad de métodos más simples, rápidos y de amplia aplicabilidad para la detección de glicoARN.

Objetivo del estudio:

Desarrollar y validar un método sencillo para la detección de glicoARN nativos mediante hibridación directa con lectinas.
Perfilar la expresión de glicoARN en diversas muestras y condiciones biológicas.

Principales métodos:

Aislamiento de ARN total seguido de Northern blot.
Hibridación directa con lectinas para la detección de glicoARN.
Comparación con métodos establecidos de detección de glicoARN.

Principales resultados:

El método de hibridación directa con lectinas es muy sensible, simple y de amplia aplicabilidad.
Se perfiló la expresión de glicoARN en tejidos humanos y murinos, líneas celulares y biofluidos (plasma, orina, líquido amniótico).
Se observaron diferencias en la expresión de glicoARN en condiciones fisiológicas y patológicas.

Conclusiones:

La hibridación directa con lectinas proporciona una alternativa fiable y reproducible para el estudio de la biología de los glicoARN.
El método permite la detección de glicoARN libres en biofluidos humanos por primera vez.
Este enfoque puede ser útil para futuros diagnósticos clínicos.
