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...

Polyprotic Acids

Polyprotic Acids

Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Mixtures of Acids

Mixtures of Acids

The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two different acids, then its pH can be determined using one of several methods depending upon the relative strength of the acids and their dissociation constants.
A Mixture of a Strong Acid and a Weak Acid
In a mixture of a strong acid and a weak acid, the strong acid dissociates completely and becomes a source of almost all the hydronium ions...

Weak Acid Solutions

Weak Acid Solutions

Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of dissolved molecules in their original form and generating a relatively small amount of hydronium ions. Weak acids are commonly encountered in nature, being the substances partly responsible for the tangy taste of citrus fruits, the stinging sensation of insect bites, and the unpleasant smells associated with body odor. A familiar example of a...

Regulation of Stroke Volume

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Amino acids

Amino acids

Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Background:

MicroRNAs (miRNA) are small noncoding RNAs regulating gene expression.
This study focuses on miRNA expression in large vessel territory cardioembolic stroke.

Purpose of the Study:

To investigate stroke-specific miRNA expression profiles in cardioembolic stroke.
To identify novel circulating miRNAs associated with ischemic stroke.

Main Methods:

Peripheral blood samples collected from controls and ischemic stroke patients within 24 hours of stroke onset.
Whole blood miRNA isolated and analyzed using miRCURY LNA™ microRNA Array for differential expression.
Pilot study included 16 patients with acute middle cerebral artery cardioembolic strokes.

Main Results:

Significant differential expression of 14 miRNAs observed in cardioembolic stroke patients versus controls.
Ten novel miRNAs, not previously linked to ischemic stroke, were identified.
An additional 5 differentially expressed miRNAs were found in severe stroke cases (NIHSS > 10).

Conclusions:

Ischemic stroke patients exhibit a distinct circulating miRNA expression profile compared to healthy individuals.
Newly identified circulating miRNAs may enhance stroke subtype diagnosis.
These miRNAs represent potential targets for novel ischemic stroke therapies.
