A 69-kDa proteinase (P69), a member of the pathogenesis-related proteins, is induced and accumulates in tomato (Lycopersicon esculentum) plants as a consequence of pathogen attack. We have used the polymerase chain reaction to identify and clone a cDNA from tomato plants that represent the pathogenesis-related P69 proteinase. The nucleotide sequence analysis revealed that P69 is synthesized in ...
Small interfering RNAs (siRNAs) and microRNAs (miRNAs) are processed by the ribonuclease Dicer from distinct precursors, double-stranded RNA (dsRNA) and hairpin RNAs, respectively, although either may guide RNA silencing via a similar complex. The siRNA pathway is antiviral, whereas an emerging role for miRNAs is in the control of development. Here, we describe a virulence factor encoded by tur...
The neuroprotective effects of electrolyzed reduced water and its model water containing molecular hydrogen and Pt nanoparticles Hanxu Yan1, Taichi Kashiwaki2, Takeki Hamasaki2, Tomoya Kinjo1, Kiichiro Teruya12,Shigeru Kabayama3 and Sanetaka Shirahata12 *Corresponding author: Sanetaka Shirahata [email protected] Author Affiliations Graduate School of Systems Life Sciences, Kyushu Un...
Intracellular survival plays a central role in the pathogenesis of Mycobacterium tuberculosis. To identify M. tuberculosis genes required for intracellular survival within macrophages, an M. tuberculosis H37Rv plasmid library was constructed by using the shuttle vector pOLYG. This plasmid library was electroporated into Mycobacterium smegmatis 1-2c, and the transformants were used to infect the...
Subtilisin-like proteins represent an ancient family of serine proteases that are extremely widespread in living organisms. We report here the structure and genomic organization of two new transcriptionally active genes encoding proteins that belong to the P69 family of subtilisin-like proteases from tomato (Lycopersicon esculentum) plants. The two new members, P69E and P69F, are organized in a...
Nuclear proteins contain a signal, termed the nuclear transport signal, that specifies their selective transport into the nucleus. Previously we reported that antibodies to Asp-Asp-Asp-Glu-Asp (DDDED) inhibited nuclear transport of nuclear proteins in vivo. We therefore tried to detect a cellular receptor of nuclear transport signals as a protein that reacted with both anti-DDDED antibody and n...
The 2-5A synthetases represent a family of proteins implicated in the mechanism of the antiviral action of interferon. When activated by double-stranded RNA, these proteins polymerize ATP into 2'-5'-linked oligomers with the general formula pppA(2'p5'A)n, n >/= 1. Three forms of human 2-5A synthetases have been described corresponding to proteins of 40/46 (p40/p46), 69/71 (p69/p71), and 100 kDa...
The effect of ethephon (2-chloroetylphosphonic acid) on the degradation of proteins and on the induction of Lycopersicon esculentum pathogenesis-related (PR) proteins was studied in tomato leaf discs. The rate of ribulose, -1,5-bisphosphate carboxylase/oxygenase (Rubisco) degradation was maximal in discs after 48 hours of incubation with 1 millimolar ethephon, leading to complete disappearance ...
Prostate cancer (PCa) is the second leading cause of cancer-related deaths in north American men, and most its related deaths are due to advanced and metastatic PCa. However, the molecular mechanisms underlying PCa progression are still unclear. Here we use a pair of prostate cell lines P69/M12, which have the same genetic background and the highly metastatic cell line M12 is a subline derived ...
