Article Abstract
Hematopoietic stem cells (HSCs) are a rare population of somatic stem cells that maintain blood production and are uniquely wired to adapt to diverse cellular fates during the lifetime of an organism. Recent studies have highlighted a central role for metabolic plasticity in facilitating cell fate transitions and in preserving HSC functionality and survival. This review summarizes our current understanding of the metabolic programs associated with HSC quiescence, self-renewal, and lineage commitment, and highlights the mechanistic underpinnings of these changing bioenergetics programs. It also discusses the therapeutic potential of targeting metabolic drivers in the context of blood malignancies.
Ankylosing spondylitis (AS) is a chronic inflammatory disease involving the spine and bone joints, which is characterized by hyperosteogeny, ossification of ligaments, and ankylosis. Quercetin is a natural polyphenolic compound with various biological activities such as antioxidant, anti-inflammatory, and anti-tumor. It was to explore the effect of quercetin on AS ossification and its molecular mechanism.

Background: Alveolar macrophages (AMs) is critical to exacerbate acute lung injury (ALI) induced by lipopolysaccharide (LPS) via inhibiting inflammation, which could by shifted by mesenchymal stem cell-derived exosomes (MSC-exos). But the underlying rationale is not fully clarified. Our study aimed to analyze the significance of itaconic acid (ITA) in mediating the protective effects of MSC-exos on LPS-induced ALI.

Bidirectional communication between pathogenic microbes and their plant hosts via small (s)RNA-mediated cross-kingdom RNA interference (ckRNAi) is a key element for successful host colonisation. Whether mutualistic fungi of the Serendipitaceae family, known for their extremely broad host range, use sRNAs to colonize plant roots is still under debate. To address this question, we developed a pipeline to validate the accumulation, translocation, and activity of fungal sRNAs in post-transcriptional silencing of Arabidopsis thaliana genes.

Objectives: Periodontal ligament stem cells (PDLSCs) are promising for regenerative therapies due to their self-renewal and multilineage differentiation, essential for periodontal tissue repair. Although magnesium plays a vital role in bone metabolism, its specific effects on PDLSCs and potential applications in regeneration are unclear. This study aimed to investigate the effects of magnesium chloride (MgCl₂) on the proliferation and osteogenic differentiation of human PDLSCs (hPDLSCs).
Over the past few years there has been an alarming burst of cancer burden worldwide. Cancer stem cells (CSCs) act as hidden devils within tumors, rendering cancer therapy a strenuous goal. Recently, the ubiquitin proteasome system (UPS) was proved to be an essential contributor to the CSC phenotype.
