Insights

Phytochemicals regulate microRNAs (miRNAs), small molecules that control gene expression. This review highlights how phytochemicals with anticancer, photoprotective, and anti-fatty liver effects modulate miRNAs for improved health.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Background:

  • Phytochemicals offer health benefits by influencing cellular processes like proliferation, apoptosis, and inflammation.
  • Their therapeutic potential against diseases, including cancer, drives research into their molecular mechanisms.
  • Emerging evidence suggests phytochemicals can regulate microRNA (miRNA) expression.

Purpose of the Study:

  • To review recent findings on phytochemicals that modulate miRNA expression.
  • To explore the health benefits, including anticancer, photoprotective, and anti-hepatosteatosis effects, associated with phytochemical-miRNA interactions.
  • To elucidate the role of target messenger RNAs (mRNAs) in these regulatory mechanisms.

Main Methods:

  • Literature review of recent studies on phytochemicals and miRNA modulation.
  • Analysis of research investigating the molecular mechanisms of phytochemical action on gene expression.
  • Synthesis of data on the therapeutic effects mediated by phytochemical-regulated miRNAs.

Main Results:

  • Phytochemicals modulate the expression of specific miRNAs.
  • These miRNA modulations contribute to anticancer, photoprotective, and anti-hepatosteatosis effects.
  • Understanding phytochemical-miRNA-mRNA interactions is key to their therapeutic application.

Conclusions:

  • Phytochemicals influence human health through miRNA-mediated gene regulation.
  • Targeting miRNAs with phytochemicals shows promise for treating cancer and other diseases.
  • Further research into these molecular pathways can optimize phytochemical-based therapies.

Models of Health Promotion and Illness Prevention II

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...

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

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...
