METTL14 Ameliorates Mitochondrial Dysfunction and Autophagy in Lens Epithelial Cells of Diabetic Cataracts via m6A Modification of RPL3

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Diabetic cataracts are a leading cause of blindness, with lens epithelial cells (LECs) exhibiting mitochondrial dysfunction and autophagy inhibition under high glucose (HG) conditions. Methyltransferase‐like 14 (METTL14), an RNA methyltransferase, regulates N6‐methyladenosine (m6A) RNA modification; however, its role in modulating ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

β‐Aminoisobutyric Acid Alleviates Cisplatin‐Induced Muscle Atrophy by Regulating E3 Ubiquitin Ligases, Apoptosis, Amino Acid Metabolism, Autophagy, and Ferroptosis

Medicine Bulletin, EarlyView.
ABSTRACT Background Cisplatin (CIS) is a widely used broad‐spectrum anticancer agent, but its clinical application is often limited by severe adverse effects, including skeletal muscle atrophy, which compromises patients' quality of life and treatment efficacy.

CMAISE: Establishing the Longitudinal Multi‐Omics Cohort for Sepsis Precision Medicine

Med Research, EarlyView.
ABSTRACT Sepsis remains a leading cause of mortality worldwide due to its profound biological heterogeneity. While multi‐omics approaches offer promise for precision medicine, existing datasets often lack longitudinal granularity or comprehensive clinical integration. We present the Chinese Multi‐omics Advances In Sepsis (CMAISE) cohort, a prospective,

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Scanning tunnelling microscopy of 16S ribosomal RNA in water

Biochemical and Biophysical Research Communications, 1991
The scanning tunnelling microscope has been used to image 16S ribosomal RNA molecules in water electrophoretically deposited on graphite surface. Two kinds of images have been obtained: images showing aggregates of 16S ribosomal RNA molecules similar to those obtained from DNA solutions and others showing individual 16S ribosomal RNA molecules.

Interaction of antibiotics with functional sites in 16S ribosomal RNA

Nature, 1987
Chemical footprinting shows that several classes of antibiotics (streptomycin, tetracycline, spectinomycin, edeine, hygromycin and the neomycins) protect concise sets of highly conserved nucleotides in 16S ribosomal RNA when bound to ribosomes. These findings have strong implications for the mechanism of action of these antibiotics and for the ...
