Recombinant Human GTPase NRas (NRAS)

1. Tet2/Nras double-mutant leukemia showed preferential sensitivity to MAPK kinase (MEK) inhibition in both mouse model and patient samples PMID: 29275866
2. Our study provided the first evidence that miR-29a suppressed lung cancer cell growth through inhibition of NRAS PMID: 29495918
3. NRAS mutations harbor commonly in neurocutaneous melanosis. PMID: 30145692
4. Ets-1 is induced by BRAF or MEK kinase inhibition, resulting in increased NRAS expression, which could be blocked by inactivation of Usp9x. PMID: 28198367
5. we used hot-spot mutation sequencing to examine whether KRAS/NRAS mutations, a characteristic feature of mesonephric carcinoma,1 are also present in mesonephric hyperplasia. None of the mesonephric hyperplasia cases harboured a KRAS or NRAS mutation. PMID: 28703285
6. BRAF mutations more frequently affected individuals younger than 61 with phototype II. In contrast, NRAS mutations were more frequent in phototype III cases. Mutations of both genes were more frequent in cases with satellitosis in the first melanoma, and in cases with ulceration in the subsequent lesions. PMID: 29180316
7. Identification of KRAS/NRAS/BRAF mutation status is crucial to predict the therapeutic effect and determine individual therapeutic strategies for patients with colorectal cancer. PMID: 29335867
8. common conjunctival melanocytic nevi have mutually exclusive mutations in BRAF and NRAS. The two conjunctival blue nevi harbored GNAQ mutations. This suggests the driver mutations of conjunctival nevi are similar to those of nevi of the skin. At the molecular level, conjunctival nevi appear more like cutaneous nevi than choroidal nevi PMID: 29332123
9. the mutational status of BRAF, NRAS, and TERT promoter genes in 97 melanomas, was investigated. PMID: 29061376
10. Deciphering KRAS and NRAS mutated clone dynamics in MLL-AF4 paediatric leukaemia by ultra deep sequencing analysis. PMID: 27698462
11. N-Ras preferentially populated raft domains when bound to mant-GDP. It lost its preference for rafts when associated with a GTP mimic, mant-GppNHp. The isolated lipidated C-terminal peptide of N-Ras was outside of the liquid-ordered rafts, most likely in the bulk-disordered lipid. Substitution of the N-Ras N-terminal G domain with a homologous G domain of H-Ras disrupted the nucleotide-dependent lipid domain switch. PMID: 29280621
12. We report herein for the first time that 30% of cutaneous NRAS mutant melanomas have a high M%NRAS. Chromosome instability, (chromosome 1 polysomy, intratumor copy number variation of chromosome1/NRAS) rather than the acquired copy neutral LOH seems to be responsible for most of the cases with high M%NRAS. PMID: 28668077
13. NRAS status (exons 2-4) was analyzed by Pyrosequencing in a case series of 50 squamous cell anal carcinoma patients. PMID: 27886225

15. Data show that mutations in NRAS are associated with poor survival. PMID: 28446505
16. s analyzed 421 samples from CLM patients for their all-RAS mutation status to compare the overall survival rate (OS), recurrence-free survival rate (RFS), and the pattern of recurrence between the patients with and without RAS mutations. PMID: 29194647
17. The lack of KRAS, NRAS, BRAF, and PIK3CA mutation in our study may suggest that a subset of eyelid sebaceous carcinomas is unlike that of eyelid sebaceous carcinomas of western countries. PMID: 28551389
18. in vitro assays confirmed that decreased miR-425 strongly induced inflammatory cytokines (interleukin [IL]-2 and interferon [IFN]-gamma) via N-Ras upregulation in the TCR signalling pathway in primary biliary cholangitis PMID: 28192189

20. analysis of K-RAS and N-RAS mutations in testicular germ cell tumors PMID: 28426398
21. KRAS mutations were rarely found together and those in codons 12 and 13 conferred poor prognosis. For BRAF, more c.1781A>G (p.D594G) colorectal cancers (CRC)carried RAS mutations [14% (3/21)] compared with c.1799T>A (p.V600E) CRCs.For NRAS, 5% (3/60) of codon 61 mutant colorectal cancers had KRAS mutations compared with 44% (10/23) of codons 12 and 13 mutant colorectal cancers PMID: 27815357
22. Mutation analysis Iindicate NRAS as the most commonly mutated gene in myeloma patients followed by KRAS ( and BRAF. PMID: 27634910
23. A rapid monophyletic evolution of melanoma subpopulations in response to targeted therapy that was not observed in non-targeted therapy was observed. NRAS mutations in BRAF mutated patient treated with a BRAF inhibitor were identified post-resistant samples. Sequence analysis showed that NRAS mutations co-occur with BRAF mutations in single cells, and are not mutually exclusive. PMID: 27791198
24. studies suggest that ZDHHC9 may serve as a safe and effective target for developing therapies against NRAS-driven cancers PMID: 26493479
25. MEK1 does not act as a general tumor suppressor in leukemogenesis. Rather, its effects strongly depend on the genetic context (RAS versus MYC-driven leukemia) and on the cell type involved. PMID: 27741509
26. Report a synthetic lethal interaction of cetuximab in combination with MEK1/2 inhibition for the NRAS mutant subgroup of metastatic colorectal cancer. PMID: 27636997
27. NRAS was identified as a direct target of let-7e and promoted oncogenesis in glioma stem cells. PMID: 27556696
28. It may be that NRAS Q61R, found in around half of GCMNs,[9] is a less potent promoter of FGF23 than the HRAS mutations usually found in verrucous EN with CSHS, and requires a larger mutant clone to cause CSHS. PMID: 27900779
29. Study showed that NRAS-mutation(+) colorectal cancer (CRC) had distinct epigenetic and clinicopathological features and significantly correlated with low-methylation epigenotypes. NRAS-mutation(+) CRC significantly correlated with less lymph vessel invasion, occurred preferentially in elder patients and at the distal colon, and showed relatively better prognosis, compared with KRAS-mutation(+) CRC.

34. An age-related increase on the frequency of NRAS mutations was observed. PMID: 27433783
35. Melanomas from geographically different regions in New Zealand have markedly different mutation frequencies, in particular in the NRAS and EPHB6 genes, when compared to The Cancer Genome Atlas database or other populations. These data have implications for the causation and treatment of malignant melanoma in New Zealand. PMID: 27191502
36. Data indicate acquired KRAS, NRAS or HRAS mutations in more than one third of patients after cetuximab exposure. PMID: 27119512
37. Mutational status of NRAS, KRAS, and PTPN11 genes is associated with genetic/cytogenetic features in children with B-precursor acute lymphoblastic leukemia. PMID: 28853218

43. Although recurrent NRAS mutations are present, the low mutation rate suggests that NRAS itself plays a minor role in the development of low-grade ovarian serous carcinoma. PMID: 28873354
44. Results show that NRAS mRNA is a direct target of microRNA miR-340. PMID: 26799668

47. Mutations in KRAS, NRAS, and BRAF together occur in more than half of all colorectal cancer cases and are often associated with negative responses to the EGFR inhibitors cetuximab and panitumumab.guideline is clear that we should not be giving EGFR inhibitors to patients with RAS mutations and that patients with BRAF V600E mutations have a much worse prognosis PMID: 28249840
