Although recent studies have suggested that the microfilament (MF) cytoskeleton of plant cells participates in the response to salt stress, it remains unclear as to whether the MF cytoskeleton actually plays an active role in a plant's ability to withstand salt stress. In the present study, we report for the first time the role of MFs in salt tolerance of(More)
In this study, we investigated the antidepressant-like effect of piperine in mice exposed to chronic mild stress (CMS) procedure. Repeated administration of piperine for 14 days at the doses of 2.5, 5 and 10 mg/kg reversed the CMS-induced changes in sucrose consumption, plasma corticosterone level and open field activity. Furthermore, the decreased(More)
Exposure to chronic stress in rodents and psychosocial stress in humans has been shown to alter cognitive functions and has been linked to the pathophysiology of mood disorders. The purpose of the present study was to investigate effects and possible mechanisms of a chronic mild stress (CMS) procedure on cognitive behaviors in Swiss albino mice using the(More)
In the present study, antidepressant-like effects of piperine (PIP) and its derivative, antiepilepsirine (AES), were investigated in two depressive models: forced swimming test (FST) and tail suspension test (TST). To further explore the mechanisms underlying their antidepressant-like activities, the brain monoamine levels and monoamine oxidase A and B(More)
Although the results of some studies indicate that salt stress affects the organization of microtubules, it remains an open question whether microtubules play an active role in the plant's ability to withstand salt stress. In the present study, we showed that salt stress-induced wild-type Arabidopsis seedling roots display right-handed skewed growth and(More)
Microtubule-associated proteins (MAPs) play important roles in the regulation of microtubule function in cells. We describe Arabidopsis thaliana MAP18, which binds to microtubules and inhibits tubulin polymerization in vitro and colocalizes along cortical microtubules as patches of dot-like structures. MAP18 is expressed mostly in the expanding cells. Cells(More)
Recent advances in the search for novel anticancer agents have indicated that the positively charged antimicrobial peptides have emerged as promising agents offering several advantages over the conventional anticancer drugs. As a naturally occurring, cationic, α-helical antimicrobial peptide, temproin-1CEa has been proved to exhibit a potent anticancer(More)
The novel polysaccharide SeGLP-2B-1 isolated from Se-enriched Ganoderma lucidum, showed anti-proliferative activity towards several cancer cell lines in vitro. To investigate the antitumor mechanisms, the apoptotic effects of SeGLP-2B-1 in human breast cancer cells were studied, and the mechanism of this action was further elucidated. Cell apoptosis was(More)
The plant cytoskeleton is a highly dynamic component of plant cells and mainly based on microtubules (MTs), and actin filaments (AFs). The important functions of dynamic cytoskeletal networks have been indicated for almost every intracellular activity, from cell division to cell movement, cell morphogenesis and cell signal transduction. Recent studies have(More)
Temporin-1CEb shows antimicrobial activity against Gram-positive bacteria, but its therapeutic potential is limited by its haemolysis. In this study, eight temporin-1CEb analogues with altered cationicities and hydrophobicities were synthesized. Increasing cationicity and amphipathicity by substituting neutral and non-polar amino acid residues on the(More)
