The ability of cancer cells to change and adapt poses a critical challenge identifying curative solutions. Tumor evolution has been extensively studied from genetic perspective, guide clinicians in selecting the most appropriate therapeutic option based on patient's mutational profile. However, several studies reported that tumors can evolve toward more aggressive stages or become resistant therapies without changing their makeup. Indeed, cell‐intrinsic cell‐extrinsic mechanisms contribute tumor evolution. In this viewpoint, I focus how chromatin, epigenetic, transcriptional changes evolution, allowing transition different cell states bypass response therapies. Although nongenetic is harder trace predict, understanding its principles might open new opportunities.

Human hematopoietic stem cells (HSCs) have traditionally been viewed as self-renewing, multipotent with enormous potential in sustaining essential steady state blood and immune cell production throughout life. Indeed, around 86% (1011-1012) of new generated daily a healthy young human adult are origin. Therapeutically, HSCs contributed to over 1.5 million transplants (HCTs) globally, making this the most successful regenerative therapy date. We will commence review by briefly highlighting selected key achievements (from 1868 end 20th century) that accomplishment. Much our knowledge hematopoiesis is based on small animal models that, despite their importance, do not always recapitulate hematopoiesis. Given this, we critically progress challenges faced identifying tracing lineage differentiation trajectories, referring murine studies needed. Moving forward given dynamic can readily adjust variety stressors, then discuss recent research advances contributing understanding (i) which HSPCs maintain hematopoiesis, (ii) where these located, (iii) mechanisms come into play when homeostatic switches stress-induced or emergency

Sex-specific differences in lifespan and ageing are observed various species. In humans, women generally live longer but frailer suffer from different age-related diseases compared to men. The hallmarks of ageing, such as genomic instability, telomere attrition or loss proteostasis, exhibit sex-specific patterns. Sex chromosomes sex hormones, well the epigenetic regulation inactive X chromosome, have been shown affect diseases. Here we review current knowledge on biological basis sex-biased ageing. While our is focused also discuss examples model organisms mouse, fruit fly killifish. Understanding these molecular crucial elderly population expected double worldwide by 2050, making approaches diagnosis, treatment, therapeutic development prevention a pressing need.

Abstract Epigenetic heterogeneity is a fundamental property of biological systems and recognized as potential driver tumor plasticity therapy resistance. Single-cell epigenomics technologies have been widely employed to study epigenetic variation between—but not within—cellular clusters. We introduce epiCHAOS: quantitative metric cell-to-cell heterogeneity, applicable any single-cell data type. After validation in synthetic datasets, we apply epiCHAOS investigate global region-specific patterns across diverse systems. EpiCHAOS provides an excellent approximation stemness development malignancy, making it valuable addition cancer analyses.
