Abstract

Insights

The matrix metalloproteinase 9 (MMP-9) gene rs3918242 polymorphism is linked to ischemic stroke (IS) risk. This genetic variant may serve as a predictor for IS susceptibility across diverse populations.

Area of Science:

  • Genetics and Molecular Biology
  • Neurology
  • Epidemiology

Background:

  • The association between the matrix metalloproteinase 9 (MMP-9) gene -1562C/T (rs3918242) polymorphism and ischemic stroke (IS) susceptibility remains unclear.
  • Previous studies yielded ambiguous and inconsistent results regarding this genetic association.

Purpose of the Study:

  • To comprehensively assess the potential relationship between the MMP-9 rs3918242 polymorphism and the risk of developing ischemic stroke.
  • To clarify the inconsistent findings from prior investigations on this genetic marker and IS.

Main Methods:

  • A meta-analysis of case-control studies was conducted.
  • Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to quantify associations.
  • Meta-regression, heterogeneity, cumulative, sensitivity, and publication bias analyses were performed.

Main Results:

  • Nineteen studies involving the rs3918242 polymorphism and IS risk were analyzed.
  • Significant associations were found in the overall population, Asians, whites, males, and females.
  • The polymorphism correlated with large artery atherosclerosis subtypes, individuals aged ≥65 years, and both diabetic and non-diabetic subgroups. Smokers showed increased IS risk.

Conclusions:

  • The MMP-9 rs3918242 polymorphism may act as a predictive marker for ischemic stroke susceptibility.
  • Further large-scale studies are warranted to validate these findings and confirm the predictive value.

Directing Effect of Substituents: meta-Directing Groups

Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

The Extracellular Matrix

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Bioavailability: Influencing Factors

Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...
