In this study, Zhang et al. provide molecular and structural insights into the cancer-relevant interaction between spliceosome factors SF3B1 and SUGP1. They further elucidate the effect of cancer-associated mutations in SF3B1 and SUGP1 that weaken their ...

Regulation of HPV16 E6 and MCL1 by SF3B1 inhibitor in head and neck cancer cells [PDF]
ABT-737 inhibits the anti-apoptotic proteins B-cell lymphoma 2 (BCL-2) and BCL-X L. Meayamycin B switches the splicing pattern of myeloid cell leukemia factor 1 (MCL1) pre-mRNA.

Co-targeting HGF/cMET Signaling with MEK Inhibitors in Metastatic Uveal Melanoma. [PDF]
Patients with metastatic uveal melanoma usually die within 1 year of diagnosis, emphasizing an urgent need to develop new treatment strategies. The liver is the most common site of metastasis.

SF3B1 is a stress-sensitive splicing factor that regulates both HSF1 concentration and activity. [PDF]
The heat shock response (HSR) is a well-conserved, cytoprotective stress response that activates the HSF1 transcription factor. During severe stress, cells inhibit mRNA splicing which also serves a cytoprotective function via inhibition of gene ...

Expression levels of SF3B3 correlate with prognosis and endocrine resistance in estrogen receptor-positive breast cancer [PDF]
De novo or acquired resistance to endocrine therapy limits its utility in a significant number of estrogen receptor-positive (ER-positive) breast cancers.

SF3B1 mutation–mediated sensitization to H3B-8800 splicing inhibitor in chronic lymphocytic leukemia
Understanding the pathogenic mechanisms of SF3B1 mutation can help unravel their contribution in patients’ worse prognosis. The cytotoxic effects and delayed leukemic infiltration induced by H3B-8800 support the potential use of SF3B1 inhibitors as a ...

The protein kinase DYRK1A phosphorylates the splicing factor SF3b1/SAP155 at Thr434, a novel in vivo phosphorylation site. [PDF]
BACKGROUND: The U2 small nuclear ribonucleoprotein particle (snRNP) component SF3b1/SAP155 is the only spliceosomal protein known to be phosphorylated concomitant with splicing catalysis.

Rare SF3B1 R625 mutations in cutaneous melanoma [PDF]
RNA splicing is the cellular process that has only recently been found to be an important target for various cancers. Among the spliceosome genes that are involved in cancers, SF3B1 is most frequently mutated. Recurrent mutation in codon 625 has been found in uveal melanoma, but this mutation has not been identified in cutaneous melanoma. We used whole-
