NRAS mutant melanoma - undrugable?

Oncotarget, 2013
Mutations in the three rat sarcoma (RAS) family members NRAS (neuroblastoma-RAS), HRAS (Harvey-RAS) and KRAS (Kirsten-RAS) are found in one third of human cancers. Among the first oncogenes discovered in cutaneous melanoma was NRAS, which is mutant in up to 20% of tumors causing aberrant signaling in several downstream cascades. Despite, being a highly

Nucleic Acid Therapeutics for “Undruggable” Cancer Targets: Mechanisms, Challenges, and Prospects

Advanced Science, EarlyView.
Nucleic acid therapeutics bypass the structural limitations of conventional drugs by targeting mRNA rather than proteins. This review examines how antisense oligonucleotides, siRNAs, miRNAs, aptamers, and mRNA vaccines intervene against historically undruggable oncoproteins including Ras, MYC, and p53, highlighting mechanistic advances, delivery ...

Impact of NRAS Mutations on the Diagnosis of Follicular Neoplasm of the Thyroid

International Journal of Endocrinology, 2014
Background. Most patients with a preoperative diagnosis of thyroid follicular neoplasm (FN) undergo diagnostic surgery to determine whether the nodule is benign or malignant.

Advances in Cancer Immunotherapy for Solid Tumors

Advanced Science, EarlyView.
Cancer immunotherapy for solid tumors is rapidly evolving beyond classical checkpoint blockade toward more precise strategies. Emerging checkpoint targets, bispecific antibodies, antibody–drug conjugate combinations, personalized vaccines, cellular therapies, and engineered cytokines are expanding therapeutic possibilities, while biomarker‐guided ...

Speeding Up the NRA Algorithm [PDF]

, 2008
Methods of top-ksearch with no random access can be used to find kbest objects using sorted access to the sources of attribute values. In this paper we present new heuristics over the NRAalgorithm that can be used for fast search of top-kobjects using wide range of user preferences.

Differential Prognostic Impact of Prior Cholecystectomy Between Proximal and Distal Colorectal Cancer: A 12‐Year Retrospective Cohort Study of 3487 Consecutive Patients

Annals of Gastroenterological Surgery, EarlyView.
In this retrospective cohort of 3487 patients with CRC, history of CCY was associated with significantly worse prognosis in patients with proximal CRC but not in those with distal CRC. This differential prognostic impact showed a statistically significant interaction between tumor location and history of CCY and remained robust after PSM.

Translational Gap in Biomarker Discovery: Tumor Surface Markers Rarely Mirror Circulating Levels

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Tumor‐associated cell surface proteins are frequently proposed as circulating biomarkers for colorectal cancer (CRC) based on their high tumor expression. However, many candidates identified through tissue‐based analyses fail to translate into clinically useful biomarkers.

Palmitoylation of oncogenic NRAS is essential for leukemogenesis

Blood, 2007
AbstractActivating mutations of NRAS are common in acute myeloid leukemia, chronic myelomonocytic leukemia, and myelodysplastic syndrome. Like all RAS proteins, NRAS must undergo a series of post-translational modifications for differential targeting to distinct membrane subdomains.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Suppression of NRAS-mutant melanoma growth with NRAS-targeting Antisense Oligonucleotide treatment reveals therapeutically relevant kinase co-dependencies

Communications Medicine
Background Melanoma is an aggressive form of skin cancer, and patients with NRAS-mutant melanoma face limited treatment options due to the lack of direct NRAS inhibitors.
