The hallmarks of cancer conceptualization is a heuristic tool for distilling the vast complexity phenotypes and genotypes into provisional set underlying principles. As knowledge mechanisms has progressed, other facets disease have emerged as potential refinements. Herein, prospect raised that phenotypic plasticity disrupted differentiation discrete hallmark capability, nonmutational epigenetic reprogramming polymorphic microbiomes both constitute distinctive enabling characteristics facilitate acquisition capabilities. Additionally, senescent cells, varying origins, may be added to roster functionally important cell types in tumor microenvironment. SIGNIFICANCE: Cancer daunting breadth scope its diversity, spanning genetics, tissue biology, pathology, response therapy. Ever more powerful experimental computational tools technologies are providing an avalanche "big data" about myriad manifestations diseases encompasses. integrative concept embodied helping distill this increasingly logical science, new dimensions presented perspective add value endeavor, fully understand development malignant progression, apply medicine.

RNA sequencing: new technologies and applications in cancer research

Journal of Hematology & Oncology, Journal Year: 2020, Volume and Issue: 13(1)

Published: Dec. 1, 2020

Abstract Over the past few decades, RNA sequencing has significantly progressed, becoming a paramount approach for transcriptome profiling. The revolution from bulk to single-molecular, single-cell and spatial approaches enabled increasingly accurate, individual cell resolution incorporated with information. Cancer, major malignant heterogeneous lethal disease, remains an enormous challenge in medical research clinical treatment. As vital tool, been utilized many aspects of cancer therapy, including biomarker discovery characterization heterogeneity evolution, drug resistance, immune microenvironment immunotherapy, neoantigens so on. In this review, latest studies on technology their applications are summarized, future challenges opportunities discussed.

Microenvironment drives cell state, plasticity, and drug response in pancreatic cancer

Prognostically relevant RNA expression states exist in pancreatic ductal adenocarcinoma (PDAC), but our understanding of their drivers, stability, and relationship to therapeutic response is limited.To examine these attributes systematically, we profiled metastatic biopsies matched organoid models at single-cell resolution.In vivo, identify a new intermediate PDAC transcriptional cell state uncover distinct site-and state-specific tumor microenvironments (TMEs).Benchmarking against this reference map, reveal strong culture-specific biases cancer representation driven by altered TME signals.We restore heterogeneity adding back vivo-relevant factors show plasticity culture models.Further, prove that non-genetic modulation can strongly influence drug responses, uncovering vulnerabilities.This work provides broadly applicable framework for aligning across vivo ex settings, identifying drivers manipulating target associated vulnerabilities.

However, while grounded in somatic selection, several lines evidence suggest Darwinian model alone insufficient fully explain cancer evolution. First, role macroevolutionary events tumour initiation progression contradicts Darwin's central thesis gradualism. Whole-genome doubling, chromosomal chromoplexy chromothripsis represent examples single catastrophic which can drive Second, neutral play some tumours, indicating that selection not always driving Third, increasing appreciation ageing soma has led generalised theories age-dependent carcinogenesis.
