Abiotic stresses cause serious damage to plants; therefore, plants undergo a complicated stress response through signal transduction originating from environmental stimuli. Here we show that a subset of short-chain leaf volatiles with an α, β-unsaturated carbonyl bond in their structure (reactive short-chain leaf volatiles, RSLVs) like (E)-2-hexenal and (E)-2-butenal can act as signal chemicals...

The effect of oxidative stress on myogenic cells with expanded CTG repeats in the myotonic dystrophy protein kinase (DMPK) gene was investigated using DMPK cDNA-transformants in order to investigate the disease process underlying myotonic dystrophy. It was reported that DM model cell was highly sensitive against oxidative stress. In this study, we investigated the viability to hydrogen peroxide...

The ABC (ATP-binding cassette) transporter family in higher plants is highly expanded compared with those of mammalians. Moreover, some members of the plant ABC subfamily B (ABCB) display very high substrate specificity compared with their mammalian counterparts that are often associated with multi-drug resistance phenomena. In this review, we highlight prominent functions of plant and mammalia...

The transmission of genetic information relies on Watson-Crick base pairing between nucleoside phosphates and template bases in template-primer complexes. Enzyme-free primer extension is the purest form of the transmission process, without any chaperon-like effect of polymerases. This simple form of copying of sequences is intimately linked to the origin of life and provides new opportunities f...

Insect odorant receptors (ORs) are 7-transmembrane receptors with inverse membrane topology. They associate with the conserved ion channel Orco. As chaperon, Orco maintains ORs in cilia and, as pacemaker channel, Orco controls spontaneous activity in olfactory receptor neurons. Odorant binding to ORs opens OR-Orco receptor ion channel complexes in heterologous expression systems. It is unknown,...

objective: oxidative stress that damages proteins result in aging and age related diseases. the aim of this study is to determine the effect of tocotrienol rich fraction (trf) on the expression of proteins in oxidative stress-induced caenohabditis elegans (c.elegans) which has homologous genes to humans. methods: the worms were treated with trf prior to, after and continuously in separate group...

Comme l’a montré Umberto Eco, les personnages littéraires célèbres, et en l’espèce de contes, deviennent des migrants qui vivent « dehors leurs partitions originales ». Tel est le phénomène que nous proposons d’aborder dans champ la littérature jeunesse contemporaine. Alors qu’ils viennent d’un passé lointain du monde forêt profonde », ces subissent effets exode rural situe désormais aventures ...

background: analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. it is necessary to investigate the synthesis of these proteins during different stress condition...
