An Engineered Nonsense \u3cem\u3eURA3\u3c/em\u3e Allele Provides a Versatile System to Detect the Presence, Absence and Appearance of the [em\u3ePSI\u3c/em\u3e\u3csup\u3e+\u3c/sup\u3e] Prion in \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e [PDF]

, 2006
Common methods to identify yeast cells containing the prion form of the Sup35 translation termination factor, [PSI+], involve a nonsense suppressor phenotype. Decreased function of Sup35p in [PSI+] cells leads to readthrough of certain nonsense mutations

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Accelerated high fidelity prion amplification within and across prion species barriers.

PLoS Pathogens, 2008
Experimental obstacles have impeded our ability to study prion transmission within and, more particularly, between species. Here, we used cervid prion protein expressed in brain extracts of transgenic mice, referred to as Tg(CerPrP), as a substrate for ...

Grass plants bind, retain, uptake, and transport infectious prions.

Cell Reports, 2015
Prions are the protein-based infectious agents responsible for prion diseases. Environmental prion contamination has been implicated in disease transmission.

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Preclinical Detection of Prions in Blood of Nonhuman Primates Infected with Variant Creutzfeldt-Jakob Disease

Emerging Infectious Diseases, 2020
Variant Creutzfeldt-Jakob disease (vCJD) is caused by prion infection with bovine spongiform encephalopathy and can be transmitted by blood transfusion. Protein misfolding cyclic amplification (PMCA) can detect prions in blood from vCJD patients with 100%

Association of recurrence patterns and outcome with HR and HER2 status in patients with resected brain metastases from breast cancer

International Journal of Cancer, EarlyView.
What's New? While treatment strategies for solid brain metastases have been relatively uniform across cancer subtypes, tailored approaches are warranted. In this observational study, intracranial recurrences after microsurgical resection occurred significantly earlier and more frequently at distant sites in patients with triple‐negative breast cancer ...

Pyridoxal Reprograms Peroxisomal Hydrogen Peroxide Metabolism to Induce Lethal Oxidative Stress in Ovarian Cancer

iMetaMed, EarlyView.
Pyridoxal (PL) exhibits the strongest anti‐tumor activity within the vitamin B6 family, demonstrating significant ovarian cancer cell‐killing efficacy in vivo, in vitro, and in patient‐derived organoid (PDO) models. The anti‐tumor mechanism involves PL inducing a shift in peroxisome dynamics towards fission, promoting peroxisome proliferation, and ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

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
