Emerging evidence suggests that cancer stem cells account for the initiation and progression of cancer. While many types of cancer stem cells with specific markers have been isolated and identified, a variety of differences among them began to be appreciated. Cancer stem cells are hierarchical populations that consist of precancerous stem cells, primary cancer stem cells, migrating cancer stem cells and chemoradioresistant cancer stem cells, playing different roles in cancer initiation and progression. Here we propose a new concept "horizontal hierarchy of cancer stem cells" to distinguish them from vertical hierarchy cancer stem cells, cancer transient-amplifying cells and cancer differentiated cells, and summarize our current understanding of these subsets of cancer stem cells with the aim to open up novel therapeutic strategies for cancer based on this understanding.

Severe combined immunodeficiency disease (SCID), characterized by profound immune system dysfunction, can lead to life-threatening infections and death. Animal models play a pivotal role in elucidating biological processes and advancing therapeutic strategies. Recent advances in gene-editing technologies, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), CRISPR/Cas9, and base editing, have significantly enhanced the generation of SCID models.

Introduction: Hematopoietic stem cell transplantation (HSCT) and chemotherapy are considered potentially curative options for post-remission therapy in acute myeloid leukemia (AML). However, the comparative effectiveness of these approaches in favorable- and intermediate-risk AML remains unclear and requires further investigation.
Methods: In this retrospective study, 111 patients diagnosed with de novo favorable- and intermediate-risk AML, categorized according to the ELN 2022 guidelines, were investigated to compare outcomes following autologous HSCT (auto-HSCT), matched sibling donor HSCT (MSD-HSCT), and chemotherapy.
Effect of long and short half-life PDE5 inhibitors on HbA1c levels: a systematic review and meta-analysis.

Background: Phosphodiesterase 5 (PDE5) inhibitors, owing to their mechanism of action, have been gaining recognition as a potential case of drug repurposing and combination therapy for diabetes treatment. We aimed to examine the effect of long and short half-life PDE5 inhibitors have on Haemoglobin A1c (HbA1c) levels.
Methods: A systematic review and meta-analysis was conducted of randomised controlled trials (RCTs) in people with elevated HbA1c (>6%) to assess mean difference in HbA1c levels from baseline versus controls after any PDE5 inhibitor intervention of ≥4 weeks, excluding multiple interventions.

Over the past two decades, research has increasingly focused on the interactions between diet, gut microbiota, and host organisms. Recent evidence suggests that tryptophan, an essential amino acid, can be metabolized by gut microbiota into indoles, which have significant biological effects. However, most research is limited to indole and its liver metabolite, indoxyl sulfate.

Background: Second primary malignancies (SPMs) are a well-known, long-term complication of antineoplastic treatment. This nationwide cohort study examined the risk of non-myeloid SPMs in survivors of adult acute myeloid leukaemia (AML) treated with intensive chemotherapy and, in some cases, allogeneic stem cell transplantation (alloSCT), compared to a matched general population.
Methods: Patients with incident AML between 2000 and 2018, alive and aged 18-70 years two years after start of intensive chemotherapy, were included and matched 1:10 to comparators from the general Danish population on sex, age, and the Nordic Multimorbidity Index.
