Cooperative Regulation of Campylobacter jejuni Heat-Shock Genes by HspR and HrcA
The heat-shock response is defined by the transient gene-expression program that leads to the rapid accumulation of heat-shock proteins. This evolutionary conserved response aims at the preservation of the intracellular environment and represents a ...

Secondary structures in polyoma DNA [PDF]
Three reproducible secondary-structure features were observed on single strands of polyoma virus DNA mounted for electron microscopy by the T4 gene 32 protein technique: (i) a hairpin fold-back extending from 92.9 +/- 0.8 to 95.0 +/- 0.7 map units; (ii ...

EMT‐associated bias in the Parsortix® system observed with pancreatic cancer cell lines
The Parsortix® system was tested for CTC enrichment using pancreatic cancer cell lines with different EMT phenotypes. Spike‐in experiments showed lower recovery of mesenchymal‐like cells. This was confirmed with an EMT‐inducible breast cancer cell line.

Characterization of a functional insertion sequence ISSau2 from Staphylococcus aureus
Background ISSau2 has been suggested as a member of the IS150 f subgroup in the IS3 family. It encodes a fusion transposase OrfAB produced by programmed − 1 translational frameshifting with two overlapping reading frames orfA and orfB.

Intramolecular integration within Moloney murine leukemia virus DNA [PDF]
By screening a library of unintegrated, circular Moloney murine leukemia virus (M-MuLV) DNA cloned in lambda phage, we found that approximately 20% of the M-MuLV DNA inserts contained internal sequence deletions or inversions.

Oligonucleotide that binds nuclear factor NF-kappa-B acts as a lymphoid-specific and inducible enhancer element [PDF]
The immunoglobulin kappa light chain gene contains a lymphoid-specific enhancer that includes several short protein-binding sequences. The sequence that binds the nuclear factor NF-kappa B was tested for its ability to act independently as an enhancer ...

Chimeric diphtheria toxin–CCL8 cytotoxic peptide for breast cancer management
DTCCL8 is a recombinant fusion toxin that targets cancer cells expressing chemokine receptors. By combining diphtheria toxin with CCL8, DTCCL8 binds to multiple receptors on tumor cells and induces selective cytotoxicity. This strategy enables receptor‐mediated targeting of cancer and may support the development of chemokine‐guided therapeutics ...

Divergent roles of CprK paralogues from Desulfitobacterium hafniense in activating gene expression [PDF]
Gene duplication and horizontal gene transfer play an important role in the evolution of prokaryotic genomes. We have investigated the role of three CprK paralogues from the cAMP receptor protein-fumarate and nitrate reduction regulator (CRP-FNR) family ...

The role of circular RNAs in regulating cytokine signaling in cancer
Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...
