PPP3CB overexpression mediates EGFR TKI resistance in lung tumors via calcineurin/MEK/ERK signaling
A triple osimertinib/calcineurin A/trametinib combination of treatment overcomes acquired resistance to EGFR TKI in EGFR-mutant lung adenocarcinoma cells that overexpress PPP3CB.

Germline variants in tumor suppressor genes (TSGs) can result in RNA mis-splicing and predisposition to cancer. However, identification of variants that impact splicing remains a challenge, contributing to a substantial proportion of patients with ...

Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]
The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

RNA structure and splicing regulation [PDF]
The process of pre-mRNA splicing is fundamental to gene regulation in eukaryotes. Specific RNA sequences called introns, which do not code for amino acids, are removed during pre-mRNA splicing, and flanking sequences are spliced together as exons forming mRNAs that are exported to the cytosol.

A trio of unique alternative splicing patterns : the splicing of tandem NAGNAG acceptors, transcription-start-site-dependent and mutually dependent cassette exons [PDF]
With the rapid increase in the volume of genomic and transcript data in mouse and human, a diverse set of alternative splicing patterns can be discovered.

Characterization of factors involved in the coupling of 3' end processing and splicing and in the 3' end formation of mRNA precursors [PDF]
Eukaryotic mRNA precursors are processed at their 5’ and 3’ ends and are spliced prior to their export from the nucleus to the cytoplasm. Although all three processing reactions can be studied separately in vitro, they are coupled in vivo.

Functional characterization of Ysh1p, the yeast endonuclease involved in 3" end processing and in transcription termination of RNA polymerase II transcripts [PDF]
Eukaryotic RNA polymerase II (RNAP II) is involved in the synthesis of two major classes of transcripts: messenger RNAs (mRNAs) and small nuclear and small nucleolar RNAs.

RNA modification and alternative splicing are central mechanisms in the regulation of eukaryotic gene expression. RNA modifications, which occur in a variety of chemical forms, exert widespread influences on RNA structure, stability and function ...

How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The splicing factor proline-glutamine rich (SFPQ/PSF) is involved in influenza virus transcription. [PDF]
The influenza A virus RNA polymerase is a heterotrimeric complex responsible for viral genome transcription and replication in the nucleus of infected cells. We recently carried out a proteomic analysis of purified polymerase expressed in human cells and
