IS200 is not a member of the IS600 family of insertion sequences [PDF]
, 1991 IS200 is an insertion sequence present in all Salmonella species except S. agona (1, 2). The element is absent from all other Enterobacteriaceae, with the exception of some strains of Shigella flexneri and Shigella sonnei (2).

Molecular Oncology, EarlyView.Plasma‐based detection of actionable mutations is a promising approach in lung cancer management. Analysis of ctDNA with a multigene NGS panel identified TP53, KRAS, and EGFR as the most frequently altered, with TP53 and KRAS in treatment‐naïve patients and TP53 and EGFR in previously treated patients.

Sequence analysis reveals extensive polymorphism and evidence of deletions within the E2 glycoprotein gene of several strains of murine hepatitis virus. [PDF]
, 1989 Direct RNA sequence analysis of the E2 gene of wild-type MHV-4 and of neutralization resistant, neuroattenuated variants has identified a polymorphic region with respect to deletions.

Stability domains of actin genes and genomic evolution
, 2007 In eukaryotic genes the protein coding sequence is split into several fragments, the exons, separated by non-coding DNA stretches, the introns. Prokaryotes do not have introns in their genome.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA
Molecular Oncology, EarlyView.Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Processing of insect retrotransposons by self-cleaving ribozymes [PDF]
, 2010 We show that several classes of insect non-LTR retrotransposons harbor self-cleaving ribozymes of the HDV family at their 5′ termini. In Drosophila the R2 ribozymes exhibit highly differential in vivo expression and robust in vitro activity ...

A Bulk-Parallel Priority Queue in External Memory with STXXL [PDF]
, 2015 We propose the design and an implementation of a bulk-parallel external memory priority queue to take advantage of both shared-memory parallelism and high external memory transfer speeds to parallel disks. To achieve higher performance by decoupling item

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway
Molecular Oncology, EarlyView.Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

alphabeta sequence of F is IS31 [PDF]
, 1975 Previous studies have shown that there is a deoxyribonucleic acid (DNA) segment, of length 1.3 kb and denoted as the alphabeta sequence, which occurs twice on the F plasmid at corrdinates 93.2 to 94.5/OF kb and 13.7 to 15.0F kb.
