Targeted Sequencing of Genomic Repeat Regions Detects Circulating Cell-free Echinococcus DNA.

Summary of "Targeted Sequencing of Genomic Repeat Regions Detects Circulating Cell-free Echinococcus DNA."

Echinococcosis is a chronic zoonosis caused by tapeworms of the genus Echinococcus. Treatment of the disease is often expensive and complicated, sometimes requiring extensive surgery. Ultrasonographic imaging is currently the main technique for diagnosis, while immunological analysis provides additional information. Confirmation still needs pathological analysis. However, these diagnostic techniques generally detect infection in late stages of the disease. An accurate, early and non-invasive molecular diagnostic method is still unavailable.

Highly Sensitive Direct Quantification of Cf-miRNAs for Biomarker Profiling by Next Generation Sequencing (NGS).

Cell-free circulating microRNAs (cf-miRNAs) are promising diagnostic and prognostic biomarkers for cancer and other diseases. cf-miRNAs are highly stable in biofluids and are therefore attractive as p...

Analysis of colorectal cancer-related mutations by liquid biopsy: utility of circulating cell-free DNA and circulating tumor cells.

We recruited 56 colorectal cancer patients and compared the mutational spectrum of tumor tissue DNA, circulating cell-free DNA, and circulating tumor cell DNA to evaluate the potential of liquid biops...

Zscan4 binds nucleosomal microsatellite DNA and protects mouse two-cell embryos from DNA damage.

Zinc finger protein Zscan4 is selectively expressed in mouse two-cell (2C) embryos undergoing zygotic genome activation (ZGA) and in a rare subpopulation of embryonic stem cells with 2C-like features....

Identification and characterization of extrachromosomal circular DNA in maternal plasma.

We explored the presence of extrachromosomal circular DNA (eccDNA) in the plasma of pregnant women. Through sequencing following either restriction enzyme or Tn5 transposase treatment, we identified e...

Medical and Biotech [MESH] Definitions

An increase number of repeats of a genomic, tandemly repeated DNA sequence from one generation to the next.

An increased number of contiguous trinucleotide repeats in the DNA sequence from one generation to the next. The presence of these regions is associated with diseases such as FRAGILE X SYNDROME and MYOTONIC DYSTROPHY. Some CHROMOSOME FRAGILE SITES are composed of sequences where trinucleotide repeat expansion occurs.

Obtaining material for pathological examination and analysis, from bodily fluids. Material retrieved includes CELL-FREE NUCLEIC ACIDS; CELL-DERIVED MICROPARTICLES; EXOSOMES; CIRCULATING NEOPLASM CELLS; and other circulating cells and CELLULAR STRUCTURES.

A large collection of DNA fragments cloned (CLONING, MOLECULAR) from a given organism, tissue, organ, or cell type. It may contain complete genomic sequences (GENOMIC LIBRARY) or complementary DNA sequences, the latter being formed from messenger RNA and lacking intron sequences.

Three regions (CDR1; CDR2 and CDR3) of amino acid sequence in the IMMUNOGLOBULIN VARIABLE REGION that are highly divergent. Together the CDRs from the light and heavy immunoglobulin chains form a surface that is complementary to the antigen. These regions are also present in other members of the immunoglobulin superfamily, for example, T-cell receptors (RECEPTORS, ANTIGEN, T-CELL).
