1. Multiple endocrine neoplasia type 2: achievements and current challenges
Incremental advances in medical technology, such as the development of sensitive hormonal assays for routine clinical care, are the drivers of medical progress. This principle is exemplified by the creation of the concept of multiple endocrine neoplasia type 2, encompassing medullary thyroid cancer, pheochromocytoma, and primary hyperparathyroidism, which di

2. Biochemistry analyses of hormonal mutant Never ripe (Nr) to cadmium and salt stresses / Análise bioquímica do mutante hormonal de tomateiro Never ripe (Nr) submetido aos estresses por cádmio e salinidade
Plant exposure to abiotic and biotic stresses can lead to enhanced production of Reactive Oxygen Species (ROS) in cells, causing oxidative stress. Cadmium (Cd) and salt (NaCl) are among the most studied abiotic stresses. Salinity can cause ion disturb in the cell, resulting in osmotic stress. In the case of Cd, it can induce nutritional, structural and bioch

3. Controle hormonal da defesa à herbivoria em tomateiro / Hormonal control of herbivory defense in tomato
Even though the cultivation of tomato has a high economical importance, this culture is classified as being of elevated risk because of it common infestation by pests and diseases. This problem makes this culture greatly dependent of the application of several agrochemicals, which leads to increase in cost of production, environmental damages and also facili

5. A Gsα mutant designed to inhibit receptor signaling through Gs
Hormonal signals activate trimeric G proteins by substituting GTP for GDP bound to the G protein α subunit (Gα), thereby generating two potential signaling molecules, Gα–GTP and free Gβγ. The usefulness of dominant negative mutations for investigating Ras and other monomeric G proteins inspired us to create a functionally analogous dominant negative G

7. Plasma Membrane Localization of Gαz Requires Two Signals
Three covalent attachments anchor heterotrimeric G proteins to cellular membranes: the α subunits are myristoylated and/or palmitoylated, whereas the γ chain is prenylated. Despite the essential role of these modifications in membrane attachment, it is not clear how they cooperate to specify G protein localization at the plasma membrane, where the G protei

8. Abnormal Stomatal Behavior and Hormonal Imbalance in flacca, a Wilty Mutant of Tomato: V. Effect of Abscisic Acid on Indoleacetic Acid Metabolism and Ethylene Evolution
The wilty tomato mutant flacca, the normal cultivar Lycopersicon esculentum Mill. Rheinlands Ruhm, and abscisic acid-induced phenotypic revertants were compared with respect to ethylene evolution, activity of tryptophan aminotransferase, and [1-14C]indoleacetic acid decarboxylation.

9. Hormonal Studies of fass, an Arabidopsis Mutant That Is Altered in Organ Elongation.
We have isolated an allele of fass, an Arabidopsis thaliana mutation that separates plant development and organ differentiation from plant elongation, and studied its hormonal regulation. Micro-surgically isolated fass roots elongate 2.5 times as much as the roots on intact mutant plants. Wild-type heart embryos, when cultured with a strong auxin, naphthalen

10. Conditional activation defect of a human Gsα mutant
Hormonal signals activate trimeric G proteins by promoting exchange of GTP for GDP bound to the G protein’s α subunit (Gα). Here we describe a point mutation that impairs this activation mechanism in the α subunit of Gs, producing an inherited disorder of hormone responsiveness. Biochemical analysis reveals an activation defect that is paradoxically int

11. Abnormal Stomatal Behavior and Hormonal Imbalance in flacca, a Wilty Mutant of Tomato: IV. Effect of Abscisic Acid and Water Content on RNase Activity and RNA
Plants of the wilty tomato (Lycopersicum esculentum) mutant, flacca, and of the normal cultivar Rheinlands Ruhm growing under either “normal” or high humidity were used in this research. Under normal humidity, RNase activity was much higher in mutant plants in which abscisic acid (ABA) and water content were lower than in the normal plant. The mutant als

12. Arabidopsis RADICAL-INDUCED CELL DEATH1 Belongs to the WWE Protein–Protein Interaction Domain Protein Family and Modulates Abscisic Acid, Ethylene, and Methyl Jasmonate Responses
Experiments with several Arabidopsis thaliana mutants have revealed a web of interactions between hormonal signaling. Here, we show that the Arabidopsis mutant radical-induced cell death1 (rcd1), although hypersensitive to apoplastic superoxide and ozone, is more resistant to chloroplastic superoxide formation, exhibits reduced sensitivity to abscisic acid,
