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

open access: yesGynecologic and Obstetric Investigation, 1994
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.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

ARTÍCULO DE RETRACTACIÓN: EXPRESIÓN DE LAS PROTEÍNAS P21 RAS Y CÁNCER. MEDICENTRO ELECTRÓN. 2007;11(1)

open access: yesMedicentro, 2017
Los genes ras pertenecen a una superfamilia de genes que codifican pequeñas proteínas de unión a nucleótidos de guanina. Las proteínas p21 Ras se localizan en la superficie interna de la membrana celular, donde actúan como interruptores moleculares ...

Activation of Bmp2-Smad1 signal and its regulation by coordinated alteration of H3K27 trimethylation in Ras-induced senescence.

open access: yesPLoS Genetics, 2011
Cellular senescence involves epigenetic alteration, e.g. loss of H3K27me3 in Ink4a-Arf locus. Using mouse embryonic fibroblast (MEF), we here analyzed transcription and epigenetic alteration during Ras-induced senescence on genome-wide scale by chromatin

Global gene analysis identifying genes commonly regulated by the Ras/Raf/MEK and type I IFN pathways

open access: yesGenomics Data, 2015
Oncolytic viruses exploit alterations in cancer cells to specifically infect cancer cells but not normal healthy cells. Previous work has shown that oncogenic Ras interferes with interferon (IFN) signaling to promote viral replication.

Mutations of RAS genes in endometrial polyps

open access: yesOncology Reports, 2019
Endometrial polyps are common, yet the molecular mechanisms underlying their formation and progression remain unclear. We examined gene mutations possibly related to the pathogenesis of endometrial polyps, as well as to their clinical features. Four premenopausal patients with endometrial polyps, who were not under drug treatment, were recruited. Whole

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Aurora kinase A (AURKA) interaction with Wnt and Ras-MAPK signalling pathways in colorectal cancer

open access: yesScientific Reports, 2018
Hyperactivation of Wnt and Ras-MAPK signalling are common events in development of colorectal adenomas. Further progression from adenoma-to-carcinoma is frequently associated with 20q gain and overexpression of Aurora kinase A (AURKA).

Targeting RAS mutants in malignancies: successes, failures, and reasons for hope

open access: yesCancer Communications, 2023
RAS genes are the most frequently mutated oncogenes and play critical roles in the development and progression of malignancies. The mutation, isoform (KRAS, HRAS, and NRAS), position, and type of substitution vary depending on the tissue types.

Gene amplifications associated with the development of hormone- resistant prostate cancer [PDF]

open access: yes, 2003
Purpose: Hormone resistance remains a significant clinical problem in prostate cancer with few therapeutic options. Research into mechanisms of hormone resistance is essential.
