Age remains one of the greatest risk factors for melanoma, and patients older than 55 have a much poorer prognosis than younger individuals, even when the data are controlled for grade and stage. The reasons for this disparity have not been fully uncovered, but there is some recent evidence that Wnt signalling may have a role. Wnt signalling is known to have roles both in cancer progression as well as in organismal ageing. In melanoma, the interplay of Wnt signalling pathways is complex, with different members of the Wnt family guiding different aspects of invasion and proliferation. Here, we will briefly review the current literature addressing the roles of different Wnt pathways in melanoma pathogenesis, provide an overview of Wnt signalling during ageing, and discuss the intersection between melanoma and ageing in terms of Wnt signalling. AGE IS A PROGNOSTIC FACTOR FOR MELANOMA also contribute to the age-induced progression of cancer. For example, it has long been proposed that the ageing stroma As human lifespan increases, there is a growing concern over the contributes to cancer progression, based on the studies using availability of treatments to manage the increasing incidence of senescence as an artificial model of ageing (Campisi, 2013; Campisi cancer in aged individuals.

Abnormal cell cycle regula- tion has been linked to many diseases. Thus, there is an urgent need to understand the diverse molecular mechanisms of how the cell cycle is controlled. RNA helicases constitute a large family of proteins with functions in all aspects of RNA metabolism, including unwinding or annealing of RNA molecules to regulate pre-mRNA, rRNA and miRNA processing, clamping protein complexes on RNA, or remodeling ribonucleoprotein complexes, to regulate gene expression. RNA helicases also regulate the activity of specific proteins through direct interaction. Abnormal expression of RNA helicases has been associated with different diseases, including cancer, neurological disorders, aging, and autosomal dominant polycystic kidney disease (ADPKD) via regulation of a diverse range of cellular processes such as cell proliferation, cell cycle arrest, and apoptosis. Recent studies showed that RNA helicases participate in the regulation of the cell cycle progression at each cell cycle phase, including G1-S transition, S phase, G2-M transition, mitosis, and cytokinesis.

Like all the other DEAD-box proteins of the same family, DDX3X participates into different steps of RNA metabolism. Moreover, DDX3X is one of the actors of cell cycle regulation, innate immunity and apoptosis processes. Our group started to look at DDX3X as an interesting protein since it has primary roles in viral infections and tumor development too. In the context of viral infections, DDX3X possesses dual roles: it acts as an antiviral or proviral factor regulating viral replication at different levels (regulation of genome duplication and/or gene expression and host innate immunity activation). From these observations, it came the idea to use DDX3X as a possible therapeutic target to inhibit a function essential for the viral replication, but dispensable for the human cell. In collaboration with the University of Siena (Prof. Maurizio Botta), we developed some inhibitor molecules able to recognize two different DDX3X pockets: the helicase binding pocket and the unique motif of DDX3X.

Summary Clinical characteristics DDX3X-related neurodevelopmental disorder (DDX3X-NDD) typically occurs in females and very rarely in males. All affected individuals reported to date have developmental delay / intellectual disability (ID) ranging from mild to severe; about 50% of affected girls remain nonverbal after age five years. Hypotonia, a common finding, can be associated with feeding difficulty in infancy. Behavioral issues can include autism spectrum disorder, attention-deficit/hyperactivity disorder and hyperactivity, self-injurious behavior, poor impulse control, and aggression. Other findings can include seizures, movement disorders (dyskinesia, spasticity, abnormal gait), vision and hearing impairment, congenital heart defects, respiratory difficulties, joint laxity, and scoliosis. Neuroblastoma has been observed in three individuals. Diagnosis/testing The diagnosis of DDX3X-NDD is established in a female proband with suggestive findings and a heterozygous de novo DDX3X pathogenic variant identified by molecular genetic testing and in a male proband with suggestive findings and a hemizygous DDX3X pathogenic variant. Management Treatment of manifestations: Treatment is symptomatic and focuses on optimizing the individual's abilities using a multidisciplinary approach that should also include psychosocial support for family members.

  • Genome-Wide Analysis of Translational Efficiency Reveals Distinct but Overlapping Functions of Yeast DEAD-Box RNA Helicases Ded1 and Eif4a
    Downloaded from genome.cshlp.org on September 27, 2021 - Published by Cold Spring Harbor Laboratory Press Research Genome-wide analysis of translational efficiency reveals distinct but overlapping functions of yeast DEAD-box RNA helicases Ded1 and eIF4A Neelam Dabas Sen,1 Fujun Zhou,1 Nicholas T. Ingolia,2 and Alan G. Hinnebusch1 1Laboratory of Gene Regulation and Development, Eunice K. Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, Maryland 20892, USA; 2Department of Molecular and Cell Biology, University of California, Berkeley, California 94720, USA DEAD-box RNA helicases eIF4A and Ded1 are believed to promote translation initiation by resolving mRNA secondary structures that impede ribosome attachment at the mRNA 5′ end or subsequent scanning of the 5′ UTR, but whether they perform unique or overlapping functions in vivo is poorly understood. We compared the effects of mutations in Ded1 or eIF4A on global translational efficiencies (TEs) in budding yeast Saccharomyces cerevisiae by ribosome footprint pro- filing. Despite similar reductions in bulk translation, inactivation of a cold-sensitive Ded1 mutant substantially reduced the TEs of >600 mRNAs, whereas inactivation of a temperature-sensitive eIF4A variant encoded by tif1-A79V (in a strain lacking the ortholog TIF2) yielded <40 similarly impaired mRNAs. The broader requirement for Ded1 did not reflect more perva- sive secondary structures at low temperature, as inactivation of temperature-sensitive and cold-sensitive ded1 mutants gave highly correlated results. Interestingly, Ded1-dependent mRNAs exhibit greater than average 5′ UTR length and propensity for secondary structure, implicating Ded1 in scanning through structured 5′ UTRs.
