Antisense inhibition of human miRNAs and indications for an involvement of miRNA in cell growth and apoptosis

Nucleic Acids Research, 2005
Of the over 200 identified mammalian microRNAs (miRNAs), only a few have known biological activity. To gain a better understanding of the role that miRNAs play in specific cellular pathways, we utilized antisense molecules to inhibit miRNA activity.

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

Molecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.

Antisense Phosphorodiamidate Morpholino Oligomers as Novel Antiviral Compounds

Frontiers in Microbiology, 2018
Phosphorodiamidate morpholino oligomers (PMO) are short single-stranded DNA analogs that are built upon a backbone of morpholine rings connected by phosphorodiamidate linkages.

Pharmacokinetics, biodistribution and cell uptake of antisense oligonucleotides.

Advanced Drug Delivery Reviews, 2015
Pharmacokinetic properties of oligonucleotides are largely driven by chemistry of the backbone and thus are sequence independent within a chemical class.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Differential expression of cellulose synthase (CesA) gene transcripts in potato as revealed by QRT-PCR [PDF]

, 2009
Two transgenic potato lines, csr2–1 and csr4–8 that contained two different antisense cellulose synthase (CesA) genes, csr2 and csr4, respectively were crossed.

Antisense antimicrobial therapeutics

Current Opinion in Microbiology, 2016
Antisense antimicrobial therapeutics are synthetic oligomers that silence expression of specific genes. This specificity confers an advantage over broad-spectrum antibiotics by avoiding unintended effects on commensal bacteria. The sequence-specificity and short length of antisense antimicrobials also pose little risk to human gene expression.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

TMC4 localizes to multiple taste cell types in the mouse taste papillae

FEBS Open Bio, EarlyView.
Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.

Meeting review : ESF workshop on "Impact of nucleic acid chemistry on gene function analysis: antisense, aptamers, ribozymes and RNAi" [PDF]

, 2008
The shortage of functional information compared to the abundance of sequence information characterizes today’s situation in functional genomics. For many years the knock-down of a gene’s product has been the most powerful way of analysing its function ...
