fusarium wilt of chickpea, caused by f. oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease, fluorescent pseudomonads were isolated from the rhizosphere of chickpea plants in khorasan province by using king,s b medium (kb). antifungal activity of 80 bacterial strains against f. oxysporum f. sp. ciceris was evaluated on kb and p...

Seed maturation is mainly governed by a few genes best studied in maize and Arabidopsis. The isolation of the LEC1 and FUS3 genes, besides the previously known VP1/AB/3 genes, and their identification as transcriptional regulators provides the first direct hints as to their molecular mode of action. With the identification of new effector genes, the investigation of the role of hormones with ne...

Macrophages dictate both initiation and resolution of inflammation. During acute inflammation classically activated macrophages (M1) predominate, and during the resolution phase alternative macrophages (M2) are dominant. The molecular mechanisms involved in macrophage polarization are understudied. MicroRNAs are differentially expressed in M1 and M2 macrophages that influence macrophage polariz...

The Helicobacter pylori toxin VacA causes vacuolar degeneration in mammalian cell lines in vitro and plays a key role in peptic ulcer disease. Two alleles, m1 and m2, of the mid-region of the vacA gene have been described, and the m2 cytotoxin always has been described as inactive in the in vitro HeLa cell assay. However, the m2 allele is associated with peptic ulcer and is prevalent in populat...

OBJECTIVE 11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) catalyzes the intracellular reduction of inactive cortisone to active cortisol, the natural ligand activating the glucocorticoid receptor (GR). Peroxisome proliferator- activated receptor-γ (PPARγ) is a nuclear receptor controlling inflammation, lipid metabolism, and the macrophage polarization state. In this study, we investigated th...

The present study aimed to investigate the interaction between miR-196 and its target gene homeobox B8 (HoxB8) in colorectal cancer (CRC) cells, and the sensitivity of miR-196 and HoxB8 to fluorouracil, leucovorin and oxaliplatin (FOLFOX4) chemotherapy (1,200 mg/m2 fluorouracil, 200 mg/m2 leucovorin and 85 mg/m2 oxaliplatin). In total, 80 tissue samples were collected in the present study. In t...

BACKGROUND An increased expression of Yes-associated protein (YAP1) has been shown to promote tumorigenesis in many cancer types including colon. However, the role of YAP1 in promoting colon tumorigenesis remains unclear. Here, we demonstrate that YAP1 expression is associated with M2 tumor-associated macrophage polarization and the generation of colon cancer stem-like cells. YAP1 downregulatio...

Different types of acute myeloid leukemia blast cells were induced to differentiate in vitro with all-trans-retinoic acid (ATRA) and vitamin D3 (VD). M0/M1 leukemic cells are not sensitive to differentiating agents, whereas M3 leukemic cells are induced to undergo granulocytic differentiation after ATRA treatment but are not sensitive to VD. M2 leukemic blast cells behave differently because th...

Beta2-adrenoceptor (beta2-ADR)-mediated vasodilatation decreases vascular reactivity and blood pressure (BP) and chromosome 5 where its gene (ADRB2R) resides and shows linkage to hypertension (HT). A Gln27Glu ADRB2R variant confers resistance to agonist-induced desensitization and enhanced vasodilator response to isoprenaline. Therefore, we carried out a case-control study in a cohort of HT and...
