Investigation of the molecular basis of PAMP-induced resistance
… compounds are dispensable for antibacterial resistance triggered by the bacterial PAMP flagellin (flg22). In addition, as an unbiased approach, I performed a novel genetic screen aimed at identifying molecular components required for induced resistance to Pto DC3000. For this, I developed a …

Induced resistance in soybean: Studies with the Mexican bean beetle and the soybean looper
Induced resistance in soybean (Glycine max), cv 'Williams 82', to the soybean looper (SBL) (Pseudoplusia includence) and the Mexican bean beetle (MBB) (Epilachna varivestis) was investigated. An increased level of antifeeding effect in soybean can be induced by previous insect herbivory as well as …

Dichloroacetate, a inhibitor of pyruvate dehydrogenase kinase-1, attenuates hypoxia-induced resistance to 5-fluorouracil in gastric cancer cells
… investigated whether gastric cancer with hypoxia-induced resistance to 5-fluorouracil (5-FU) could be re-sensitized following treatment with low-dose dichloroacetate (DCA), an inhibitor of the glycolytic pathway. The expression profile of hypoxia-inducible factor-1α (HIF-1α) and pyruvate …

Physiological, biochemical and molecular aspects of induced resistance in maize against Bipolaris maydis infection using a zinc-polyphenolic compound and silicon
… concentration of silicon (Si) or the use of resistance inducers may be promising alternatives for boosting maize resistance against MLB. The first study investigated the potential of using Semia® [zinc (20%) complexed with plant- derived pool of polyphenols (10%)] to boost defense reactions …

Identification of the cir1 disease resistance gene in Arabidopsis thaliana
… The defence-related cir1 (constitutively induced resistance 1) mutant was first isolated in an effort to identify components of the Arabidopsis thaliana defence system essential for resistance against pathogens. The cir1 mutant has previously been described as having increased resistance …

Investigation of defence mechanisms against Botrytis cinerea in Arabidopsis thaliana
Disease resistance in plants has been extensively studied for the past century with many new and exciting results being discovered each year. A plant utilises both preformed and induced defence responses to resist pathogen attack but researchers have focused on dissecting the induced defence …

Certain biological comparisons of resistant and non-resistant strains of the German cockroach, Blattella Germanica (Linnaeus)
… approached unity in all strains. Correlation of resistance with differences found in this study gave variable results. The field-originated strain (chlordane-resistant) was similar to the normal strain in average length of incubation and nymphal developmental periods, but similar to the other …

Functional identification of molecular oncotargets associated with the resistance to ALK inhibition in neuroblastoma via genome-wide CRISPR-Cas9 screens
… simple to target therapeutically. However, resistance to ALK-targeted therapy, particularly in ALK+ NSCLC patients has frequently been observed. The majority of the acquired resistance mechanisms noted in NSCLC patients rely on bypass signalling pathways, which are tissue-context dependent. …

Characterisation of the AT4G11100 gene, a negative regulator of disease resistance in Arabidopsis thaliana
… The Arabidopsis thaliana cir1 (constitutively induced resistance 1) mutant displays enhanced resistance to infection by the virulent bacterial pathogen Pseudomonas syringae and constitutively expresses a number of defence genes. Evidence suggests that CIR1 is a negative regulator of plant …

Superconducting nanowire single-photon detectors and sub-10-nm lithography
… that, beyond the initial formation of a photon-induced resistance across the nanowire, Joule heating results in the growth of the resistive segment. While simple, this model was useful in designing SNSPDs that reset more quickly, and also in explaining an undesirable behavior of the SNSPDs where …

The multifactorial nature of hypoxia-induced drug resistance in cancer: involvement of hypoxia-inducible factor 1
… of intratumoral hypoxia is associated with resistance to therapy in many forms of human cancer, and pre-exposure of tumor cells to hypoxia confers multidrug resistance. Research over the last several years has led to considerable advances in the understanding of the cellular response to …

Intercropping with resistant cultivars reduces early blight and root knot disease on susceptible cultivars of tomato (Lycopersicon esculentum)
… that SA accumulation may contribute to increased resistance in 'Juliet'. In greenhouse experiments, there was a trend toward increased production of salicylic acid content in the leaves of 'Brandywine' when planted with resistant cultivars compared to those next to 'Brandywine', however this was …

Risposte di resistenza a batteri fitopatogeni di importanti specie coltivate indotte da molecole segnale di diversa natura
… products. Antagonistic/beneficial bacteria and resistance inducers may have a great potential in the prophylaxis of diseases caused by common and quarantine pathogens. This work was carried out to confirm the ability of the known strain IPV-BO G19 (Pseudomonas fluorescens) against fire blight …

The Immunosuppressive Function of VEGF Signaling in the Tumor Microenvironment
Angiogenesis, a hallmark of cancer, is induced by vascular endothelial growth factor-A (VEGF). As a result, anti-VEGF therapy is commonly employed for cancer treatment. However, anti-VEGF therapy generally provides modest efficacy in cancer patients and therapy-induced hypoxia results in a less …

Mapping PAMP Responses and Disease Resistance in Brassicas
… it may have potential to provide durable disease resistance in the field. Limiting this work, however, is an absence of reliable bioassays to investigate PAMP responses in some species. Presented here is a series of methods to investigate PTI in Brassica napus. The assays allow measuring early …

The Role of Prolactin in the Cellular Response to DNA Damaging Agents
… Prolactin is also involved in breast cancer resistance to different chemotherapeutics. The overall goal of this project is to investigate potential pathways involved in prolactin induced resistance to DNA damaging agents with the hypothesis that the cross-talk between the prolactin pathway …

Quantitative methods for in vitro and in vivo characterization of cell and tissue metabolism
… including lower survival rates. Hypoxia-induced resistance to radiotherapy presents an intriguing clinical opportunity because boosting the radiation dose can overcome the radiotherapy resistance present in hypoxic tumor subvolumes. Existing oxygen-sensing methods are not sufficient to …

Influence of salicylate and abscisic acid on the resisitance of tomato to biotrophic and necrotrophic pathogens
… the SA defence pathway activated both basal and induced resistance against B. cinerea but not against O. neolycopersici. The reverse effects were observed in tobacco, indicating that plant defence responses activated by the SA-dependent pathway depend on the specific host–pathogen system. Another …
