Exploiting DNA Damage Response in the Era of Precision Oncology
No full textThis eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

A Comparative Analysis of Individual RAS Mutations in Cancer Biology.
Full text linkIn human cells, three closely related RAS genes, termed HRAS, KRAS, and NRAS, encode four highly homologous proteins. RAS proteins are small GTPases involved in a broad spectrum of key molecular and cellular activities, including proliferation and survival among others. Gain-of-function missense mutations, mostly located at codons 12, 13, and 61, constitutively activate RAS proteins and can be detected in various types of human cancers. KRAS is the most frequently mutated, followed by NRAS and HRAS. However, each isoform exhibits distinctive mutation frequency at each codon, supporting the hypothesis that different RAS mutants may lead to distinct biologic manifestations. This review is focused on the differences in signaling and phenotype, as well as on transcriptomics, proteomics, and metabolomics profiles related to individual RAS-mutated variants. Additionally, association of these mutants with particular targeted outcomes and rare mutations at additional RAS codons are discussed
Beyond keratinocyte differentiation: emerging new biology of small proline-rich proteins.
Full text linkSmall proline-rich proteins (SPRRPs) are traditionally known for their function in keratinocyte homeostasis. Recent evidence demonstrates their involvement in additional diverse physiological processes ranging from p53 signaling and direct prevention of DNA damage to bactericidal activities. We highlight these novel, intriguing roles of SPRRPs and discuss them in the context of relevant pathological conditions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
PO-1446 Systematic Review of Prognostic and Predictive Biomarkers in HNSCC Treated with Radiotherapy
No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Oncogene addiction as a foundation of targeted cancer therapy: The paradigm of the MET receptor tyrosine kinase.
No full textFollowing nearly two decades of its conception, the phenomenon of oncogene addiction still represents a key concept of how progresses in basic research can translate to unprecedented translational breakthroughs. Coined by Bernard Weinstein, this term refers to the phenomenon by which cancer cells can exhibit dependence on a single oncogenic protein or signaling pathway for sustaining proliferation and survival, despite the wide burden of genetic lesions characterizing their genomic background, revealing thus a promising Achilles' heel of cancer. Importantly, this concept aided the design and clinical implementation of molecularly targeted anticancer therapies, further supporting the paradigm shift witnessed in clinical oncology towards an individual-based, personalized era. In this review, we outline the path of discovery concerning the oncogene addiction concept and focus on the MET receptor tyrosine kinase as a model addicting oncoprotein to further explore potential and pitfalls stemming from the implementation of anticancer strategies targeting tumor dependencies beyond their blending with other therapeutic opportunities
