What is Gene Expression?01:42

What is Gene Expression?

196.5K
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...

RNA Polymerase II Accessory Proteins

10.9K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

RNA Interference01:23

RNA Interference

28.0K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

RNA Structure

79.0K
Overview
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...

RNA Stability01:53

RNA Stability

35.7K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

16.5K
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...

Area of Science:

  • Molecular Biology
  • Genetics
  • Immunology

Background:

  • Long noncoding RNAs (lncRNAs) are implicated in autoimmune and immune-associated disorders.
  • Understanding the specific role of lncRNAs in psoriasis pathogenesis is crucial for developing targeted therapies.

Purpose of the Study:

  • To identify lncRNAs specifically associated with psoriasis.
  • To investigate the potential diagnostic and therapeutic value of these lncRNAs.

Main Methods:

  • Microarray analysis of lncRNA and mRNA expression in psoriasis patient biopsies versus healthy controls.
  • Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for validation of selected lncRNAs.
  • Bioinformatic analyses including Gene Ontology, pathway analysis, and co-expression network analysis.

Main Results:

  • Microarray identified 2,194 dysregulated lncRNAs and 1,725 dysregulated mRNAs in psoriasis.
  • 1,549 lncRNAs were predicted to have cis- or trans-regulated target genes.
  • RT-qPCR validated the differential expression of 7 out of 10 selected lncRNAs, with 3 upregulated and 4 downregulated.

Conclusions:

  • lncRNAs are significantly dysregulated in psoriasis and may contribute to its pathogenesis.
  • Specific lncRNAs show potential as diagnostic biomarkers and therapeutic targets for psoriasis.
  • The combined action of multiple lncRNAs may be involved in the development of psoriasis.
