Quantitative analysis of snoRNA association with pre-ribosomes and release of snR30 by Rok1 helicase [PDF]

, 2008
In yeast, three small nucleolar RNAs (snoRNAs) are essential for the processing of pre-ribosomal RNA—U3, U14 and snR30—whereas 72 non-essential snoRNAs direct site-specific modification of pre-rRNA. We applied a quantitative screen for alterations in the

Pt‐TiO2 mesoporous nanosystem co‐delivering phlorezin enables synergistic sonodynamic‐chemoimmunotherapy for hepatocellular carcinoma via directly targeting DDX5 and metabolic reprogramming modulation

BMEMat, EarlyView.
Abstract Hepatocellular carcinoma (HCC), ranking as the third leading cause of cancer‐related mortality globally, continues to pose significant therapeutic challenges. Here, we developed an innovative nanosystem, Phl@PT, based on Pt‐TiO2 nanoparticles for the co‐delivery of Phlorezin, presenting a novel approach for HCC treatment through sonodynamic ...

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

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 ...
