psiCLIP reveals dynamic RNA binding by DEAH-box helicases before and after exon ligation

open access: yesNature Communications, 2021
ATP-dependent helicases remodel the spliceosome and proofread splice site recognition. A new method – Purified Spliceosome iCLIP (psiCLIP) – probes protein-RNA interactions in defined spliceosome complexes to reveal how the helicases Prp16 and Prp22 ...

Effective affinities in microarray data

open access: yes, 2006
In the past couple of years several studies have shown that hybridization in Affymetrix DNA microarrays can be rather well understood on the basis of simple models of physical chemistry.

DNA hybridization to mismatched templates: a chip study [PDF]

open access: yes, 2001
High-density oligonucleotide arrays are among the most rapidly expanding technologies in biology today. In the {\sl GeneChip} system, the reconstruction of the target concentration depends upon the differential signal generated from hybridizing the ...

Probing RNA Structure by Lead Cleavage [PDF]

open access: yesCurrent Protocols in Nucleic Acid Chemistry, 2000
AbstractLead cleavage causes a transesterification reaction that breaks the 5′,3′‐phosphodiester backbone of RNA, leaving a 2′,3′‐cyclic phosphate and a 5′‐hydroxyl. Since the efficiency of the reaction at the 2′‐hydroxyl is related to steric and chemical constraints on particular 2′‐hydroxyls embedded in the RNA, this reaction can be used to examine ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

HybriSeq: probe-based device-free single-cell RNA profiling

open access: yesCommunications Biology
We have developed the HybriSeq method for single-cell RNA profiling, which utilizes in situ hybridization of multiple probes for targeted transcripts, followed by split-pool barcoding and sequencing analysis of the probes. We have shown that HybriSeq can

Fluorescent Probes for Nucleic Acid Visualization in Fixed and Live Cells

open access: yesMolecules, 2013
This review analyses the literature concerning non-fluorescent and fluorescent probes for nucleic acid imaging in fixed and living cells from the point of view of their suitability for imaging intracellular native RNA and DNA. Attention is mainly paid to

Gene Expression and the Physiological Role of Transforming Growth Factor-α in the Mouse Pituitary [PDF]

open access: yes, 2003
Transforming growth factor-alpha (TGF-alpha), a member of the epidermal growth factor (EGF) family, is produced within the mouse anterior pituitaries. However, the cell types of TGF-alpha-expressing cells and the physiological roles of TGF-a within mouse

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.
