abscisic acid/neoplasms

Crown gall tumors induced by Agrobacterium tumefaciens represent a sink that has to be provided with nutrients and water by the host plant. The lack of an intact epidermis or cuticle results in uncontrolled loss of water. However, neither the tumor nor the host plant displays wilting. This

BACKGROUND Mercury (Hg) is not only a threat to public health but also a growth risk factor to plants, as it is readily accumulated by higher plants. Accumulation of Hg in plants disrupts many cellular-level functions and inhibits growth and development; however, the detoxification and tolerance

In order to identify genes involved in cold acclimation, we have constructed a cDNA library from Brassica napus (cv. Samouraï) cold-acclimated etiolated seedlings. By differential screening, a cDNA clone named pBnC24 (Brassica napus Cold), corresponding to a new cold-inducible plant gene, was

Abscisic acid (ABA) is a phytohormone regulating important functions in higher plants, notably responses to abiotic stress. Recently, chemical or physical stimulation of human granulocytes was shown to induce production and release of endogenous ABA, which activates specific cell functions. Here we

As a widely known plant hormone, Abscisic acid plays an important role in the progress of planting cell and their stress response. Recently, we reported that ABA might play an anti-cancer role in glioma tissues. In the present study, the molecular mechanism of ABA anti-cancer was further explored in

Livingston-Wheeler's cancer treatment is based on the belief that cancer is caused by a bacterium she has named Progenitor cryptocides. Careful research using modern techniques, however, has shown that there is no such organism and that Livingston-Wheeler has apparently mistaken several different

Roussoella species are well recorded from both monocotyledons and dicotyledons. As part of a research program to discover biologically active compounds from plant-associated Dothideomycetes in Thailand, the strain Roussoella sp. (MFLUCC 17-2059), which represents an undescribed species, was isolated

BACKGROUND Helicobacter pylori (H. pylori) is linked to the development of the majority of peptic ulcers and some types of gastric cancers, and its antibiotic resistance is currently found worldwide. OBJECTIVE This study is aimed at evaluating the anti-H. pylori activity of Korean acacia honey and

The biotrophic pathogen Ustilago maydis causes tumors by redirecting vegetative and floral development in maize (Zea mays L.). After fungal injection into immature tassels, tumors were found in all floral organs, with a progression of organ susceptibility that mirrors the sequential location of foci

Tumor necrosis factor receptor-associated factor (TRAF) proteins play crucial roles in plant development and response to abiotic stress. Here, we present genetic evidence that SEVEN IN ABSENTIA 2 (SINA2), a TRAF-like family protein, is involved in abscisic acid (ABA)-related drought stress signaling

The plant selective autophagy cargo receptor neighbour of breast cancer 1 gene (NBR1) has been scarcely studied in the context of abiotic stress. We wanted to expand this knowledge by using Arabidopsis thaliana lines with constitutive ectopic overexpression of the AtNBR1 gene (OX lines) and the

Chemical examination of Chinese mangrove Rhizophora mucronata endophytic Pestalotiopsis sp., yielded 11 known metabolites with various structure types, including demethylincisterol A3 (1), dankasterone B (2), (22E, 24R)-ergosta-7,9(11), 22-triene-3β, 5α, 6α-triol (3), ergosta-5,7,22-trien-3-ol (4),

Ischemic retinopathies (IRs) are the main cause of severe visual impairment and sight loss, and are characterized by loss of blood vessels, accompanied by hypoxia, and neovascularization. Actual therapies, based on anti-vascular endothelial growth factor (VEGF) strategies, antioxidants or

Crown gall tumors develop after integration of the T-DNA of virulent Agrobacterium tumefaciens strains into the plant genome. Expression of the T-DNA-encoded oncogenes triggers proliferation and differentiation of transformed plant cells. Crown gall development is known to be accompanied by global

Activity-guided fractionation of the leaves of Macaranga triloba, using an in vitro bioassay based on the inhibition of cyclooxygenase-2, resulted in the isolation of a rotenoid, 4,5-dihydro-5'alpha-hydroxy-4'alpha-methoxy-6a,12a-dehydro-alpha-toxicarol (1), as well as 12 known compounds,
