1. MSK1 was overexpressed in 148 out of 329 colorectal cancer (CRC) patients. CRC patients with high MSK1 expression had shorter overall survival than those with low MSK1, especially among patients with stage III tumors. Overexpression of MSK1 is associated with poor prognosis in CRC and is connected to tumor aggressiveness. PMID: 28314603

3. Our findings indicate that MSK1/beta-catenin signaling serves as an escape survival signal upon PI3K inhibition and provides a strong rationale for the combined use of PI3K and MSK1/beta-catenin inhibition to induce lethal growth inhibition in human GBM cells. PMID: 27196759
4. Results show that MSK1 phosphorylates H3S10 through p38-MAPK pathway in gastric cancer patients. PMID: 27588146
5. Interrupting MSK1 activation is a new target for antioxidants. PMID: 26030901
6. Increased MSK1 activity is critically important for Epstein-Barr virus LMP1-promoted cell proliferation and transformation. PMID: 25958199
7. Authors conclude that paramyxoviruses trigger the DNA damage response, a pathway required for MSK1 activation of phospho Ser 276 RelA formation to trigger the IRF7-RIG-I amplification loop necessary for mucosal interferon production. PMID: 25520509
8. These results highlight the relevance of MSK1 in the up-regulation of RARbeta by prostaglandin E2. PMID: 24953041

12. MSK1 is an important downstream kinase involved in CS-induced NF-kappaB activation PMID: 22312446
13. MSK1 is a direct and potent transcriptional activator when targeted to c-fos promotor, and when targeted to alpha-globin promoter induces H3 S28 phosphorylation reactivating expression of this polycomb-silenced gene. PMID: 21282660
14. In this study, by applying a novel method, we have identified the phosphorylation sites in human MSK1 mitogen- and stress-activated protein kinase 1, and show that MRK-beta could also activate MSK1 through direct interaction. PMID: 20408143
15. MiR-148a attenuates paclitaxel resistance of hormone-refractory, drug-resistant prostate cancer PC3 cells by regulating MSK1 expression PMID: 20406806
16. Bile acid regulates MUC2 transcription in colon cancer cells via positive EGFR/PKC/Ras/ERK/CREB, PI3K/Akt/IkappaB/NF-kappaB and p38/MSK1/CREB pathways and negative JNK/c-Jun/AP-1 pathway. PMID: 20198339
17. The MSK1 can be phosphorylated and activated in cells by both ERK1/2 and p38alpha. PMID: 20044958
18. Data provide evidence that p38 Map kinase pathway is activated leading to increased upregulation of mixed lineage kinase 3, MKK3/6, MSK1, and Mapkapk2, upon treatment of BCR/ABL expressing cells with dasatinib. PMID: 19672773
19. IL1beta and TNFalpha activation of MSK1 and CREB and cAMP-response element signaling cascades occurs via ERK/p38 MAP kinases and are crucial aspects of the intracellular mechanisms that mediate MUC5AC gene expression PMID: 12690113
20. acetylation of histones may stimulate transcription by suppressing an inhibitory phosphorylation by MSK1 PMID: 15010469
21. MSK1 has a role in transforming growth factor-beta-mediated responses through p38alpha and Smad signaling pathways PMID: 15133024
22. essential role of the C-terminal domain of MSK1 for its constitutive interaction with group V secretory phospholipase A(2), which appears essential to support VEGF-mediated PAF synthesis PMID: 16479592
23. Plays a positive role in the control of cell proliferation of both HaCaT keratinocytes and the A431 human epidermoid carcinoma line. PMID: 16532028
24. As MSK1 regulates the production of pro-inflammatory cytokines, it may play a role in the pathogenesis of psoriasis. PMID: 16543895
25. MSK1 has a role downstream of p38 in the regulation of As2O3 responses PMID: 16762916
26. Thr700 phosphorylation relieves the inhibition of MSK1 by a C-terminal autoinhibitory helix and helps induce a conformational shift that protects Thr581 from dephosphorylation PMID: 17117922
27. the induction of inflammatory genes by farnesol is mediated by the activation of the NF-kappaB pathway and involves MEK1/2-ERK1/2-MSK1-dependent phosphorylation of p65/RelA(Ser(276)) PMID: 18424438
28. This study provides therefore a direct link between MSK1-mediated phosphorylation of Ser276 p65 of NF-kappaB, allowing its binding to the SCF intronic enhancer, and pathophysiological SCF expression in inflammation. PMID: 19197368
29. IL-17F may be involved in airway inflammation and remodeling via the induction of IL-11, and RafI-MEK1/2-ERK1/2-MSK1-CREB is identified as a novel signaling pathway. PMID: 19251839
30. Data reveal that TPA activates transcription of TBX2 through activating MSK1, which leads to an increase in phosphorylated histone H3 and the recruitment of Sp1 to the TBX2 gene. PMID: 19633291
31. We conclude that RSV induces RelA activation in the innate inflammatory response via a pathway separate from that controlling RelA cytoplasmic release, mediated by ROS signaling to cytoplasmic MSK1 activation and RelA Ser-276 phosphorylation. PMID: 19706715
