A simple and efficient method for extraction of genomic DNA from tropical tuber crops [PDF]

open access: yes, 2010
DNA extraction in many plants is difficult because of metabolites that interfere with DNA isolation procedures and subsequent applications, such as DNA restriction, amplification and cloning. We havedeveloped a reliable and efficient method for isolating

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

CUTseq is a versatile method for preparing multiplexed DNA sequencing libraries from low-input samples

open access: yesNature Communications, 2019
Genomics DNA library preparation from formalin-fixed paraffin-embedded tissues is challenging. Here the authors describe CUTseq that uses restriction enzymes and in vitro amplification to barcode samples for reduced representation genome sequencing.

Simple enzymatic means to neutralize DNA contamination in nucleic acid amplification

open access: yesBioTechniques, 2005
Reverse transcription PCR (RT-PCR) is prone to false positives when contaminating DNA molecules are present at the start of a reaction. Contaminants that derive from earlier work using a given primer pair (carryover PCR products) are of particular ...

DNA Hash Pooling and its Applications [PDF]

open access: yesarXiv, 2007
In this paper we describe a new technique for the comparison of populations of DNA strands. Comparison is vital to the study of ecological systems, at both the micro and macro scales. Existing methods make use of DNA sequencing and cloning, which can prove costly and time consuming, even with current sequencing techniques.

Sequence-specific double-strand cleavage of DNA by penta-N-methylpyrrolecarboxamide-EDTA·Fe(II) [PDF]

open access: yes, 1983
In the presence of O2 and 5 mM dithiothreitol, penta-N-methylpyrrolecarboxamide-EDTA·Fe(II) [P5E·Fe(II)] at 0.5 µ M cleaves pBR322 plasmid DNA (50 µ M in base pairs) on opposite strands to afford discrete DNA fragments as analyzed by agarose gel ...

Multiplex single‐cell profiling of putative cancer stem cell markers ALDH1, SOX9, SOX2, CD44, CD133 and CD15 in endometrial cancer

open access: yesMolecular Oncology, EarlyView.
Cancer stem cells are associated with aggressive disease, but a deep characterization of such markers is lacking in endometrial cancer. This study uses imaging mass cytometry to explore putative cancer stem cell markers in endometrial tumors and corresponding organoid models.

An alternative approach to study the enzymatic specificities of the CfrBI restriction–modification system

open access: yesHeliyon, 2019
Restriction–modification systems (RMS) are the main gene-engineering tools and a suitable model to study the molecular mechanisms of catalysis and DNA–protein interactions.
