Examination of herpes virus DNA sequences for patterns that resemble transposable elements
1Department of Microbiology, University of Texas Health Science Center at Houston, Dental Branch 77225.
Summary
Herpes viruses may cause oral tumors by inserting DNA sequences. Computer algorithms identified more of these viral insertion sequences than previously known, suggesting they play a role in cell transformation.
Area of Science:
- Virology
- Bioinformatics
- Genetics
Background:
- Herpes viruses are linked to oral tumors and exhibit in vitro tumorigenicity.
- The precise mechanisms of herpes virus-induced cell transformation are not fully understood.
- Insertion sequences within herpes virus DNA are hypothesized to be involved in tumorigenesis.
Purpose of the Study:
- To develop and evaluate algorithms for detecting specific patterns in DNA sequences.
- To identify potential insertion sequences within herpes virus DNA.
- To assess the role of these sequences in viral cell transformation.
Main Methods:
- Development of two distinct algorithms: one based on selection and another on scoring techniques.
- Application of these algorithms to analyze DNA sequences of herpes viruses.
- Comparison of algorithm performance on randomly shuffled versus known herpes virus sequences.
Main Results:
- Both algorithms detected numerous patterns in shuffled herpes virus sequences.
- The scoring algorithm identified fewer patterns than the selection algorithm in shuffled sequences.
- Computer analysis revealed significantly more known insertion patterns in herpes virus DNA than previously reported.
Conclusions:
- Visual inspection is insufficient for identifying all relevant patterns in herpes virus DNA.
- The high frequency of detected patterns suggests herpes virus DNA transforming regions may contain transposable elements.
- Further experimental validation is required to confirm the presence and function of transposable elements in herpes virus-mediated cell transformation.

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Key Elements for Plant Nutrition
24.1K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Periodic Classification of the Elements
58.8K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

LTR Retrotransposons
19.6K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.
