As climate changes, there is a need to understand the expected effects on viticulture. In nature, stresses exist in a combined manner, hampering the elucidation of the effect of individual cues on grape berry metabolism. Cell suspension culture originated from pea-size Gamy Red grape berry was used to harness metabolic response to high light (HL; 2500 μmol m(-2)s(-1)), high temperature (HT; 40°...
Introduction & Objective: Hodgkin lymphoma accounts for about 1% of all cancers. Cyclooxygenase 2 (COX2) is a cytoplasmic enzyme. Oncogene, and growth factor induce over expression of COX2. COX2 is apoptotic inhibitor. Mutation of the p53 tumor suppressor gene represents the most common genetic alternation in human tumors. This study aimed to evaluate the expression of COX2 and p53 in subtype...
The differentiating agent and histone deacetylase inhibitor, sodium butyrate (NaB), was shown previously to cause a transient, 3-17-fold induction of human DNA topoisomerase II alpha (topo II alpha) gene promoter activity and a 2-fold increase in topo II alpha protein early in monocytic differentiation of HL-60 cells. This observation has now been extended to other short chain fatty acids and a...
We demonstrated previously that Actinobacillus actinomycetemcomitans leukotoxin (Ltx) is greatly able to induce apoptotic signaling in cells that are positive for lymphocyte function-associated antigen 1 (LFA-1), a cell receptor of Ltx. We investigated in this study whether inflammatory cytokines can regulate apoptosis of human leukemic HL-60 cells induced by Ltx. Of the cytokines tested, tumor...
Health literacy (HL) is defined as the capacity of a person to acquire, interpret, and understand basic information and health services that is necessary for proper decision making. Some researchers believe that HL is a stronger predictor of health as compared to variables such as age, sex, income, employment status, education level, and race [1]. HL can be an effective factor in increasing hea...
Introduction and purpose: Health literacy (HL) is a relatively new emerging concept in public health, which is the capacity of Individuals to obtain, process, and understand basic health information and services needed to make proper health decisions. This study aimed to assess the level of health literacy among the individuals aged between 18 and 65 years old in Shahriar, I...
An anthracycline-resistant subline of HL-60 promyelocytic leu kemia cells (HL-60/AR) has been isolated in vitro by subculturing in progressively higher concentrations of Adriamycin. The resis tant cells are capable of sustaining continuous growth in 10~6 M Adriamycin which is more than 50 times the 50% inhibitory dose for the parent line. HL-60/AR expressed variable degrees of cross-resistance ...
The companion cells (CCs) and/or phloem parenchyma cells (PCs) in foliar minor veins of some species exhibit invaginations that are amplified when plants develop in high light (HL) compared to low light (LL). Leaves of plants that develop under HL also exhibit greater maximal rates of photosynthesis compared to those that develop under LL, suggesting that the increased membrane area of CCs and ...
Vitamin K2 (menaquinone-4: VK2) is a potent inducer for apoptosis in leukemia cells in vitro. HL-60bcl-2 cells, which are derived from a stable transfectant clone of the human bcl-2 gene into the HL-60 leukemia cell line, show 5-fold greater expression of the Bcl-2 protein compared with HL-60neo cells, a control clone transfected with vector alone. VK2 induces apoptosis in HL-60neo cells, where...
The protective action of quercetin against the pro-oxidant and apoptotic effect of etoposide was investigated in HL-60 cells with a high level of myeloperoxidase (MPO) activity and in cells treated with MPO inhibitor, 4-aminobenzoic acid hydrazide (ABAH). Quercetin significantly protected MPO-rich cells against the pro-oxidative (p<0.05) and apoptotic (p<0.05) effects of etoposide. Pre-treatmen...
