Elevated NRAS expression during DCIS is a potential driver for progression to basal-like properties and local invasiveness

Breast Cancer Research, 2022
Background Ductal carcinoma in situ (DCIS) is the most common type of in situ premalignant breast cancers. What drives DCIS to invasive breast cancer is unclear. Basal-like invasive breast cancers are aggressive.

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

Advanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

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

A Panel of Circulating Exosomal sncRNAs Associated With Lung Cancer Risk up to 10 Years in Advance

Advanced Science, EarlyView.
Lung cancer is often diagnosed too late, and current screening overlooks many people at risk. In a long‐term study of smokers, a panel of small non‐coding RNAs carried in blood exosomes signals elevated lung cancer risk up to ten years before diagnosis, pointing toward a blood‐based tool for earlier risk detection.

The TUBA1B–G3BP2 Axis Sustains p65 Transcriptional Activity to Promote Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
TUBA1B is consistently upregulated in hepatocellular carcinoma and sustains malignant progression by stabilizing G3BP2. By restraining TRIM25‐associated K48‐linked ubiquitination, TUBA1B preserves the G3BP2–IκBα complex and basal NF‐κB/p65 activity. Concurrent TUBA1B/G3BP2 upregulation identifies an aggressive HCC subgroup with enhanced p65 activation ...

Prevalence of BRAF, NRAS and c-KIT mutations in Slovenian patients with advanced melanoma

Radiology and Oncology, 2018
BRAF, NRAS and c-KIT mutations are characteristics of tumour tissues that influence on treatment decisions in metastatic melanoma patients. Mutation frequency and their correlation with histological characteristics in Slovenian population have not been ...

Cooperative Epigenetic Remodeling by TET2 Loss and NRAS Mutation Drives Myeloid Transformation and MEK Inhibitor Sensitivity [PDF]

, 2018
Mutations in epigenetic modifiers and signaling factors often co-occur in myeloid malignancies, including TET2 and NRAS mutations. Concurrent Tet2 loss and NrasG12D expression in hematopoietic cells induced myeloid transformation, with a fully penetrant,

Similarity‐Enhanced Representation Learning of Non‐Canonical Amino Acids for Therapeutic Peptide Modeling

Advanced Science, EarlyView.
Non‐canonical amino acids (ncAAs) enhance peptide therapeutics but remain difficult to model computationally. SinCAA, a similarity‐enhanced pretraining framework, jointly optimizes contrastive learning guided by a novel conformational similarity metric with masked node reconstruction, capturing both functional relationships and chemical identity of ...

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.
