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

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

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.

Proteomic Characterization of AS1411 Reveals ATP6AP1 as a Mediator of Triple‐Negative Breast Cancer Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by high metastatic potential, poor prognosis, and limited effective therapeutic options. In this study, we investigated the molecular mechanisms underlying the anticancer effects of the nucleolin (NCL)‐targeting DNA aptamer AS1411 using label‐free ...

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

RNA degradomics and proteomics reveal the mechanism of dsProsβ1‐mediated proteasome targeting in Psylliodes chrysocephala

Pest Management Science, EarlyView.
RNA degradomics revealed dsProsβ1‐derived siRNA‐mediated mRNA cleavage events, mainly at uracil‐guanine and adenine‐adenine pairs. Proteasome inhibition via dsProsβ1 increased mitochondrial and cytoskeletal proteins while reducing translation‐related and mRNA‐binding proteins.

Resistance of Botrytis cinerea to anilinopyrimidine fungicides: A novel ARMS‐PCR method for the detection of Bcpos5 mutations and characterization of resistance using CRISPR/Cas9 editing

Pest Management Science, EarlyView.
A TETRA‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method was developed for simultaneous detection of the L412F/V and G408V mutations. L412F/V mutants were created using the CRISPR/Cas tool and no fitness cost was observed.

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by
