On ras gene function in yeast. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1985
Saccharomyces cerevisiae contains two RAS genes, RAS1 and RAS2. An insertion mutation in RAS2 (ras2::LEU2) does not affect growth on glucose based media but it does prevent growth on media with pyruvate or other noncarbohydrate carbon sources. This defect is pH sensitive and is most severe at pH 7 and above. The ras2::LEU2 mutation also causes markedly

Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

open access: yesAdvanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...

Analysis of Η-ras, K-ras and Ν-ras genes for expression, mutation and amplification in laryngeal tumours

open access: yes, 2008
Journal URL: http://www.spandidos-publications.com/ijo/The levels of expression of the ras family genes, in 14 tumour specimens from squamous cell carcinomas of the larynx were analysed by reverse transcription-polymerase chain reaction.

The coordination of cell growth during fission yeast mating requires Ras1-GTP hydrolysis [PDF]

open access: yes, 2013
The spatial and temporal control of polarity is fundamental to the survival of all organisms. Cells define their polarity using highly conserved mechanisms that frequently rely upon the action of small GTPases, such as Ras and Cdc42.

INFLUENCE OF THE POLYMORPHISM OF THE RENIN-ANGIOTENSIN SYSTEM GENES ON THE CARDIAC ARRHYTHMIAS IN CHILDREN WITH HYPERTROPHIC CARDIOMYOPATHY

open access: yesВопросы современной педиатрии, 2013
Hypertrophic cardiomyopathy (HCMP) is a genetically determined myocardial disease, characterized by massive hypertrophy of the myocardium of the left and/or (rarely) the right ventricle, often associated with obstruction of the left ventricular outflow ...

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

G3BP1 Succinylation at K413 is Critical for Cardiac Function by Modulating PI3K‐AKT‐mTOR Signal Axis

open access: yesAdvanced Science, EarlyView.
Schematic illustrating the impact of G3BP1 succinylation at K413 on cardiac function. In the healthy human heart, G3BP1 succinylation maintains homeostatic mTOR signaling. In patients with dilated cardiomyopathy (DCM) and heart failure (HF), G3BP1 de‐succinylation induces RagA expression and disrupts the binding of the TSC1/2 complex, leading to the ...

Stress History Establishes a Transient Tolerant State That Shapes Antibiotic Survival Upon Resuscitation

open access: yesAdvanced Science, EarlyView.
High‐throughput single‐cell analysis of resuscitating bacteria reveals a starvation‐history‐dependent transiently tolerant subpopulation that survives β$\beta$‐lactam exposure by temporarily reducing growth. Distinct from classical persisters, these actively growing yet dynamically modulated cells dominate survival across clinically relevant antibiotic

S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

open access: yesAdvanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...
