Extracranial Vascular Anomalies Driven by RAS/MAPK Variants: Spectrum and Genotype–Phenotype Correlations

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background We aimed to correlate alterations in the rat sarcoma virus (RAS)/mitogen‐activated protein kinase pathway in vascular anomalies to the clinical phenotype for improved patient and treatment stratification. Methods and Results This retrospective

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

FEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Suppressible and nonsuppressible autocrine mast cell tumors are distinguished by insertion of an endogenous retroviral element (IAP) into the interleukin 3 gene [PDF]

, 1993
After v-H-ras expression, the interleukin 3 (IL-3)-dependent PB-3c mast cells progress in vivo to two different classes of IL-3 autocrine tumors. Class I tumors show a germline configuration of the IL-3 gene and represent more than 90% of tumors analyzed

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Generation of specific antibodies against the rap1A, rap1B and rap2 small GTP-binding proteins. Analysis of rap and ras proteins in membranes from mammalian cells

, 1992
Specific antibodies against rap1A and rap1B small GTP-binding proteins were generated by immunization of rabbits with peptides derived from the C-terminus of the processed proteins.

A Role for Mitochondrial Translation in Promotion of Viability in K-Ras Mutant Cells

Cell Reports, 2017
Activating mutations in the KRAS oncogene are highly prevalent in tumors, especially those of the colon, lung, and pancreas. To better understand the genetic dependencies that K-Ras mutant cells rely upon for their growth, we employed whole-genome CRISPR

Analysis of p53 and ras Gene Mutations in Endometriosis [PDF]

Gynecologic and Obstetric Investigation, 2010
No activating mutations in codons 12,13 and 61 of ras genes nor inactivating mutations in exons 5–9 of the p53 tumor suppressor gene were detected by polymerase chain reaction and single-strand conformation polymorphism methods in either eutopic or ectopic endometrium from 10 women with severe endometriosis.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Alterations in gene expression associated with invasion of RAS-mutant thyroid tumors and their potential diagnostic and therapeutic utility

European Thyroid Journal
Introduction: Mutations of RAS genes are detected in a spectrum of follicular-patterned thyroid tumors. Preoperative prediction of invasive cancers based on the presence of RAS mutation alone is challenging because non-invasive and invasive tumors tend ...
