Transcriptional profiling of colicin-induced cell death of Escherichia coli MG1655 identifies potential mechanisms by which bacteriocins promote bacterial diversity [PDF]

open access: yes, 2004
We report the transcriptional response of Escherichia coli MG1655 to damage induced by colicins E3 and E9, bacteriocins that kill cells through inactivation of the ribosome and degradation of chromosomal DNA, respectively. Colicin E9 strongly induced the

Membrane fusion mediated by ricin and viscumin [PDF]

open access: yes, 1998
The ribosome inactivating plant proteins (RIPs) ricin and viscumin but not Ricinus communis agglutinin are able induce vesicle–vesicle fusion. A model is suggested in which the toxicity of the RIPs is partially determined by their fusogenicity.

Anti-Human Endoglin (hCD105) Immunotoxin—Containing Recombinant Single Chain Ribosome-Inactivating Protein Musarmin 1

open access: yesToxins, 2016
Endoglin (CD105) is an accessory component of the TGF-β receptor complex, which is expressed in a number of tissues and over-expressed in the endothelial cells of tumor neovasculature.

Combination of Balsamin and Flavonoids Induce Apoptotic Effects in Liver and Breast Cancer Cells

open access: yesFrontiers in Pharmacology, 2020
Flavonoids such as naringenin, quercetin, and naringin are known to exhibit anticancer properties. In this study, we examined the effects of these flavonoids on cell viability and apoptotic pathways of cancer cells, either singly or in combination with ...

Plant Toxins as Potential Alternatives to Botulinum Toxin for Eye-Movement Disorder Therapy

open access: yesStresses, 2023
The most successful alternative to traditional surgery for ocular muscle spasm treatment is the intramuscular injection of botulinum toxin (BTX), which allows the maintenance of the muscle dynamics and the absence of scars.

Inhibition of HIV-1 replication by balsamin, a ribosome inactivating protein of Momordica balsamina [PDF]

open access: yes, 2013
Ribosome-inactivating proteins (RIPs) are endowed with several medicinal properties, including antiviral activity. We demonstrate here that the recently identified type I RIP from Momordica balsamina also possesses antiviral activity, as determined by ...

Effect of transgenic tobacco plant, Nicotiana tabacum expressing ribosome inactivating gene isolated from the bulbs of Dutch iris, Iris hollandica on biological parameters of Myzus nicotianae (Hem.: Aphididea) and Spodoptera exigua (Lep.: Noctuidae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2015
The use of modified crop plants through gene transfer between different plant species plays an important role in pest control programs. We have investigated the insecticidal properties of two lines of tobacco transgenic plant consisting of IRIP ...

Impairing the production of ribosomal RNA activates mammalian target of rapamycin complex 1 signalling and downstream translation factors [PDF]

open access: yes, 2014
Ribosome biogenesis is a key process for maintaining protein synthetic capacity in dividing or growing cells, and requires coordinated production of ribosomal proteins and ribosomal RNA (rRNA), including the processing of the latter.

Ribosome inactivation by Escherichia coli GTPase RsgA inhibits T4 phage

open access: yesFrontiers in Microbiology, 2023
IntroductionBacteria must combat phages, and myriad bacterial anti-phage systems have been discovered that reduce host metabolism, for example, by depleting energetic compounds like ATP and NAD+. Hence, these systems indirectly inhibit protein production.

Lectin domains at the frontiers of plant defense [PDF]

open access: yes, 2014
Plants are under constant attack from pathogens and herbivorous insects. To protect and defend themselves, plants evolved a multi-layered surveillance system, known as the innate immune system.
