Molecular Responses to Climate Change: How Warming and Acidification Reshape the Proteome and Phosphoproteome of the Endangered Mira Chub

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Global environmental change affects organisms, including their physiology. In freshwater ecosystems, where migration is limited, populations often rely on phenotypic plasticity to respond. While transcriptomics has been widely used to study stress responses at the molecular level, less is known about the proteome, which reflects post ...

RNA Regulatory Networks: Key Hubs in the Panorama of Cancer and Emerging Therapeutic Targets

MedComm, Volume 7, Issue 3, March 2026.
RNA regulatory networks play a crucial role in the initiation and progression of cancer through various modes of RNA interactions. Notably, circulating RNAs have emerged as potential biomarkers, while targeted interventions in RNA regulatory networks facilitate precise therapeutic strategies. ABSTRACT Cancer is a global health challenge. The initiation

Structural investigation of human U6 snRNA recognition by spliceosomal recycling factor SART3 RNA recognition motifs

The FEBS Journal, Volume 293, Issue 5, Page 1323-1340, March 2026.
Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.

S-allylmercaptocysteine inhibits TLR4-mediated inflammation through enhanced formation of inhibitory MyD88 splice variant in mammary epithelial cells

Scientific Reports
Mastitis is an inflammatory disease affecting mammary tissues caused by bacterial infection that negatively affects milk quality and quantity. S-Allylmercaptocysteine (SAMC), a sulfur compound in aged garlic extract (AGE), suppresses lipopolysaccharide ...

The Influence of Cell Isolation and Culturing on Natriuretic Peptide Receptors in Aortic Vascular Smooth Muscle Cells

Cells
Vascular smooth muscle cell (SMC) relaxation by guanylyl cyclases (GCs) and cGMP is mediated by NO and its receptor soluble GC (sGC) or natriuretic peptides (NPs) ANP/BNP and CNP with the receptors GC-A and GC-B, respectively.

Gezielte Modulation des spliceosomalen Proteins USP39 durch allosterische Liganden und PROTAC‐induzierte Degradation

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Proteolysis‐targeting Chimeras (PROTACs) ermöglichen die gezielte Degradation bislang als „undruggable“ geltende Proteine über das zelluläre Ubiquitin–Proteasom‐System. In dieser Studie identifizieren Schäfer et al. thiazolbasierte niedermolekulare Liganden, die allosterisch an die Zinkfinger‐Domäne der Ubiquitin‐spezifischen Protease 39 (USP39) binden

A Block in Mammalian Splicing Occurring after Formation of Large Complexes Containing U1, U2, U4, U5, and U6 Small Nuclear Ribonucleoproteins [PDF]

Molecular and Cellular Biology, 1989
The assembly of mammalian pre-mRNAs into large 50S to 60S complexes, or spliceosomes, containing small nuclear ribonucleoproteins (snRNPs) leads to the production of splicing intermediates, 5' exon and lariat-3' exon, and the subsequent production of spliced products.

Targeting the Spliceosomal Protein USP39 Through Allosteric Ligands and PROTAC‐Induced Degradation

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Proteolysis‐targeting chimeras (PROTACs) enable degradation of proteins previously considered undruggable by harnessing the cellular ubiquitin–proteasome system. In this study, Schäfer et al. identify thiazole‐based small molecules that allosterically bind the zinc finger domain of ubiquitin‐specific protease 39 (USP39), a non‐enzymatic scaffold ...

The 5' splice site consensus RNA oligonucleotide induces assembly of U2/U4/U5/U6 small nuclear ribonucleoprotein complexes. [PDF]

Proceedings of the National Academy of Sciences, 1992
A short RNA oligonucleotide comprising the 5' splice site consensus sequence (5'SS RNA oligo) efficiently inhibits splicing of mRNA precursors in HeLa cell nuclear extracts. Addition of 5'SS RNA oligo inhibits early, but not late, steps in the splicing reaction, affecting the process of spliceosome assembly. In the presence of 5'SS RNA oligo a majority
