Slow non-specific accumulation of 2′-deoxy and 2′-O-methyl oligonucleotide probes at mitochondria in live cells

Nucleic Acids Research, 2010
Molecular beacons (MBs) have the potential to provide a powerful tool for rapid RNA detection in living cells, as well as monitoring the dynamics of RNA expression in response to external stimuli. To exploit this potential, it is necessary to distinguish

Endoglin mediates the tumor‐ and metastasis‐promoting traits of stromal myofibroblasts in human breast carcinomas

Molecular Oncology, EarlyView.
Carcinoma‐associated fibroblasts (CAFs) in tumors influence cancer progression. We identified endoglin (ENG) as a key factor in TGF‐β signaling in myofibroblastic CAFs (myCAFs), linked to poor breast cancer outcomes. Inhibiting ENG on myCAFs suppressed the TGF‐β‐Smad2/3 pathway, reducing primary tumor growth and metastasis.

Integrative miRNOMe profiling reveals the miR‐195‐5p–CHEK1 axis and its impact on luminal breast cancer outcomes

Molecular Oncology, EarlyView.
In luminal (ER+) breast carcinoma (BC), miRNA profiling identified miR‐195‐5p as a key regulator of proliferation that targets CHEK1, CDC25A, and CCNE1. High CHEK1 expression correlates with worse relapse‐free survival after chemotherapy, especially in patients with luminal A subtype.

Phosphorylated lipid-conjugated oligonucleotide selectively anchors on cell membranes with high alkaline phosphatase expression

Nature Communications, 2019
Attachment of lipid tails to oligonucleotides has emerged as a powerful technology in constructing cell membrane-anchorable nucleic acid-based probes.

Ferrocene-oligonucleotide conjugates for electrochemical probing of DNA [PDF]

Nucleic Acids Research, 1996
Toward the development of a universal, sensitive and convenient method of DNA (or RNA) detection, electrochemically active oligonucleotides were prepared by covalent linkage of a ferrocenyl group to the 5'-aminohexyl-terminated synthetic oligonucleotides. Using these electrochemically active probes, we have been able to demonstrate the detection of DNA

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Improving signal intensities for genes with low-expression on oligonucleotide microarrays

BMC Genomics, 2004
Background DNA microarrays using long oligonucleotide probes are widely used to evaluate gene expression in biological samples. These oligonucleotides are pre-synthesized and sequence-optimized to represent specific genes with minimal cross-hybridization

SNPs analysis by use of protected oligonucleotide probes [PDF]

Nucleic Acids Symposium Series, 2005
Loss of large amounts of DNA probe occurred at the deprotection step of the in situ synthesis of DNA microarrays for analysis of SNPs or gene expression. In this study, we developed "Protected Oligonucleotide Probes" that can avoid elimination of probe DNAs and allow their highly efficient synthesis.

Characterization of WAC interactions with R2TP and TTT chaperone complexes linking glucose and glutamine availability to mTORC1 activity

FEBS Open Bio, EarlyView.
TTT and R2TP chaperone complexes are required for the assembly and activation of mTORC1. WAC directly interacts with components of TTT, R2TP, and mTORC1, and these interactions are affected by the availability of glucose and glutamine, correlating with changes in mTORC1 activity.

Experimental optimization of probe length to increase the sequence specificity of high-density oligonucleotide microarrays

BMC Genomics, 2007
Background High-density oligonucleotide arrays are widely used for analysis of genome-wide expression and genetic variation. Affymetrix GeneChips – common high-density oligonucleotide arrays – contain perfect match (PM) and mismatch (MM) probes generated
