Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
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 pre-miRNA...
DNA Microarrays02:34

DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Area of Science:

  • Molecular Biology
  • Parasitology
  • Genomics

Context:

  • Schistosoma japonicum is a parasitic flatworm responsible for schistosomiasis.
  • Understanding gene function is crucial for developing targeted interventions.
  • The specific role of the Sj34.9 gene in S. japonicum remains largely uncharacterized.

Purpose:

  • To elucidate the functional role of the Sj34.9 gene in Schistosoma japonicum.
  • To identify downstream genes and pathways affected by Sj34.9 knockdown.
  • To provide a foundational reference for future research on Sj34.9.

Summary:

  • RNA interference (RNAi) was employed to knock down the Sj34.9 gene in S. japonicum.
  • Microarray analysis revealed 378 differentially expressed genes (202 upregulated, 176 downregulated) post-knockdown.
  • Affected genes are primarily associated with organelle function, metabolism, signal transduction, binding, membrane formulation, and cellular processes.
