Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Harnessing Phytochemicals for Brain Cancer Therapy: Insights Into Medulloblastoma and Glioblastoma Treatment

Phytochemical Analysis, EarlyView.
ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...
