Plant cell death: Unmasking the gatekeepers
نویسنده
چکیده
Cell death is an important aspect of plant resistance to pathogen infection. Recent results have shed new light on the mechanisms that control this cell death following attempted pathogen infection.

G1 Phase Arrest and Apoptosis Induction in Human Thyroid Cancer Cell Line Thr.C1.PI33 by 3-Hydrogenkwadaphnin Isolated from Dendrostellera lessertii
Dendrostellera lessertii (Thymelaeaceae) is a toxic plant that grows in parts of Iran. The anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-HK), have been established using several cancer cell lines. Methods: In a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...

Objective: This study was planned to investigate whetherCoriandrum sativum (C. sativum) is capable of protecting neurons against glucose/serum deprivation (GSD)-induced cytotoxicity. Material and Methods: The PC12 cells were cultivated for 24 h in standard media (high-glucose DMEM containing Fetal Bovine Serum) or for 6 h in GSD condition (glucose-free DMEM, without serum) in the absence or pr...
متن کاملConserved Nonsense-Prone CpG Sites in Apoptosis-Regulatory Genes: Conditional Stop Signs on the Road to Cell Death
Methylation-prone CpG dinucleotides are strongly conserved in the germline, yet are also predisposed to somatic mutation. Here we quantify the relationship between germline codon mutability and somatic carcinogenesis by comparing usage of the nonsense-prone CGA (→TGA) codons in gene groups that differ in apoptotic function; to this end, suppressor genes were subclassified as either apoptotic (g...
متن کاملA computational model for regulation of nanoscale glucan exposure in Candida albicans
Candida albicans is a virulent human opportunistic pathogen. It evades innate immune surveillance by masking an immunogenic cell wall polysaccharide, β-glucan, from recognition by the immunoreceptor Dectin-1. Glucan unmasking by the antifungal drug caspofungin leads to changes in the nanostructure of glucan exposure accessible to Dectin-1. The physical mechanism that regulates glucan exposure i...

One way of controlling plant response to various biotic stresses occurs through programmed cell death, this system is known as the hypersensitive reaction. Plant resistance system against stress is stimulated through different chemicals such as salicylic acid. Therfore, experiment was conducted in a completely randomized design with three replications, in order to identifying the expressed pr...
