Cancer chemoprevention with PV-1, a novel Prunella vulgaris-containing herbal mixture that remodels the tumor immune microenvironment in mice

open access: yesFrontiers in Immunology, 2023
The herb Prunella vulgaris has shown significant immune-stimulatory and anti-inflammatory effects in mouse models. Here, the effects of a novel Prunella vulgaris-containing herbal mixture, PV-1, were examined in several mouse models for cancer, including

Comparative evaluation of antimutagenic and antimitotic effects of Morchella esculenta extracts and protocatechuic acid [PDF]

open access: yes, 2013
Morchella esculenta (L.) Pers. methanolic extracts, obtained from fruiting bodies growing wild in Serbia and Portugal, were screened for their antimutagenic properties and compared to protocatechuic acid, previously identified in both species. Salmonella

Reduction in squamous cell carcinomas in mouse skin by dietary zinc supplementation. [PDF]

open access: yes, 2016
Inadequate dietary Zn consumption increases susceptibility to esophageal and other cancers in humans and model organisms. Since Zn supplementation can prevent cancers in rodent squamous cell carcinoma (SCC) models, we were interested in determining if it

Synthesis and Reaction of 3-Fluoro-4-nitroquinoline 1-Oxide

open access: yesChemical and Pharmaceutical Bulletin, 1968
3-Fluoroquinoline 1-oxide, which was prepared through the Schiemann reaction of 3-aminoquinoline, followed by N-oxygenation, was nitrated to 3-fluoro-4-nitroquinoline 1-oxide. The fluorine atom of this compound was replaced with nucleophiles such as OR- or NR2-containing compounds in neutral or alkaline media to afford 3-substituted 4-nitroquinoline 1 ...

TNFα Signaling Is Increased in Progressing Oral Potentially Malignant Disorders and Regulates Malignant Transformation in an Oral Carcinogenesis Model

open access: yesFrontiers in Oncology, 2021
Oral carcinogenesis represents a multi-stage process which encompasses several genetic and molecular changes that promote the progression of oral potentially malignant disorders (OPMDs) to oral squamous cell carcinomas (OSCCs).

The Genetic Basis of Mutation Rate Variation in Yeast. [PDF]

open access: yes, 2018
Mutations are the root source of genetic variation and underlie the process of evolution. Although the rates at which mutations occur vary considerably between species, little is known about differences within species, or the genetic and molecular basis ...

Identification and dissection of a complex DNA repair sensitivity phenotype in Baker's yeast. [PDF]

open access: yesPLoS Genetics, 2008
Complex traits typically involve the contribution of multiple gene variants. In this study, we took advantage of a high-density genotyping analysis of the BY (S288c) and RM strains of Saccharomyces cerevisiae and of 123 derived spore progeny to identify ...

5-Methoxytryptophan Sensitizing Head and Neck Squamous Carcinoma Cell to Cisplatitn Through Inhibiting Signal Transducer and Activator of Transcription 3 (STAT3)

open access: yesFrontiers in Oncology, 2022
Head and neck squamous cell carcinoma (HNSCC) is a common cancer of the oral cavity. Cisplatin (CDDP) is the ideal chemo-radiotherapy used for several tumor types, but resistance to the drug has become a major obstacle in treating patients with HNSCC.
