Role of RNA structure and protein factors in the control of HIV-1 splicing

Frontiers in Bioscience, 2009
Alternative splicing plays a key role in the production of numerous proteins by complex lentiviruses such as HIV-1. The study of HIV-1 RNA splicing has provided useful information not only about the physiology of the virus, but also about the general mechanisms that regulate mammalian pre-mRNA alternative splicing.

Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

Advanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Functional coordination of alternative splicing in the mammalian central nervous system [PDF]

, 2007
BACKGROUND: Alternative splicing (AS) functions to expand proteomic complexity and plays numerous important roles in gene regulation. However, the extent to which AS coordinates functions in a cell and tissue type specific manner is not known.

Large‐scale Whole‐Exome Sequencing Defines the Protein‐Coding Architecture of Retinal Structure, Visual Function, and Major Blinding Diseases

Advanced Science, EarlyView.
Large‐scale whole‐exome sequencing in 356,982 UK Biobank participants defines the protein‐coding architecture of retinal structure, visual function, and major blinding diseases. Pleiotropic genes, including CFI, C3, and RIOX1, bridge multiple retinal phenotypes, while experimental validation of FYB2 implicates RPE barrier dysfunction, providing ...

AEP promotes aberrant RNA splicing through DDX3X cleavage in solid tumors

The Journal of Clinical Investigation
Aberrant alternative splicing (AS) events have been identified in a variety of cancers. Although somatic mutations of splicing factors and dysregulation of RNA-binding proteins (RBPs) have been linked to AS and tumor malignancy, it remains unclear how ...

Microprotein MP104 Promotes Malignant Progression of Colorectal Cancer Through Regulating Protein Translation

Advanced Science, EarlyView.
A previously unrecognized microprotein, MP104, encoded by ZEB1‐AS1, emerges as a critical driver of colorectal cancer progression. MP104 links ubiquitin‐mediated protein degradation with translational reprogramming via the UBE2O–AMPKα2–mTOR–EIF4B axis, revealing an unrecognized layer of oncogenic regulation.

CA9‐Targeted PET Imaging for Noninvasive Discrimination of Clear Cell Renal Cell Carcinoma and Associated Tumor Biological Features

Advanced Science, EarlyView.
CA9‐targeted PET imaging could be a noninvasive approach to characterize clear cell renal cell carcinoma and associated tumor biology. PET uptake correlates with tumor CA9 expression and is linked to angiogenic activity, immune remodeling, and metabolic reprogramming.

Cancer-associated snaR-A noncoding RNA interacts with core splicing machinery and disrupts processing of mRNA subpopulations

Nature Communications
Expansion of RNA polymerase III (Pol III) activity in cancer can activate the transcription of typically silent small RNA genes, including snaR-A (small NF90-associated RNA isoform A), a hominid-specific noncoding RNA that promotes cell proliferation ...

Evidence for a nuclear compartment of transcription and splicing located at chromosome domain boundaries [PDF]

, 1993
The nuclear topography of splicing snRNPs, mRNA transcripts and chromosome domains in various mammalian cell types are described. The visualization of splicing snRNPs, defined by the Sm antigen, and coiled bodies, revealed distinctly different ...
