The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

18.7K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

18.0K
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

682
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...

Anaphase Promoting Complex00:50

Anaphase Promoting Complex

3.3K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Models of Health Promotion and Illness Prevention II01:18

Models of Health Promotion and Illness Prevention II

2.0K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Area of Science:

  • Immunology
  • Genetics
  • Virology

Background:

  • C-C chemokine receptor 5 (CCR5) polymorphisms, including the ∆32 deletion and the -2459G > A promoter variant, are linked to HIV-1 infection and progression.
  • Current HIV cure research heavily focuses on the CCR5 ∆32 deletion, potentially overlooking the significance of other CCR5 variants.

Purpose of the Study:

  • To highlight the underappreciated role of the CCR5 -2459G > A polymorphism in HIV-1 infection and disease.
  • To emphasize the importance of integrating CCR5 -2459G > A genotype data into HIV research and treatment strategies.

Main Methods:

  • Review of existing literature on CCR5 polymorphisms and HIV-1.
  • Analysis of the potential impact of CCR5 -2459G > A on treatment response and disease progression.

Main Results:

  • The CCR5 -2459G > A polymorphism offers a mechanistic explanation for variations in HIV-1 response.
  • Ignoring this variant may lead to incomplete understanding of treatment efficacy and disease outcomes.

Conclusions:

  • Incorporating CCR5 -2459G > A genotype information is vital for optimizing immunologic and chemotherapeutic strategies for HIV-1.
  • Understanding all CCR5 variants is essential for advancing HIV/AIDS management and public health efforts.
