Question: Context: To increase the Zn level in shoots, AtHMA4 was ectopically expressed in tomato under the constitutive CaMV 35S promoter. However, the Zn concentration in the shoots of transgenic plants failed to increase at all tested Zn levels in the medium. Modification of Zn root/shoot distribution in tomato expressing 35S::AtHMA4 depended on the concentration of Zn in the medium, thus indicating involvement of unknown endogenous metal-homeostasis mechanisms. To determine these mechanisms, those metal-homeostasis genes that were expressed differently in transgenic and wild-type plants were identified by microarray and RT-qPCR analysis using laser-assisted microdissected RNA isolated from two root sectors: (epidermis\u2009+\u2009cortex and stele), and leaf sectors (upper epidermis\u2009+\u2009palisade parenchyma and lower epidermis\u2009+\u2009spongy parenchyma).', 'Zn-supply-dependent modification of Zn root/shoot distribution in AtHMA4-tomato (increase at 5\xa0μM Zn, no change at 0.5\xa0μM Zn) involved tissue-specific, distinct from that in the wild type, expression of tomato endogenous genes. First, it is suggested that an ethylene-dependent pathway underlies the detected changes in Zn root/shoot partitioning, as it was induced in transgenic plants in a distinct way depending on Zn exposure. Upon exposure to 5 or 0.5\xa0μM Zn, in the epidermis\u2009+\u2009cortex of the transgenics\' roots the expression of the Strategy I Fe-uptake system (ethylene-dependent LeIRT1 and LeFER) was respectively lower or higher than in the wild type and was accompanied by respectively lower or higher expression of the identified ethylene genes (LeNR, LeACO4, LeACO5) and of LeChln. Second, the contribution of LeNRAMP2 expression in the stele is shown to be distinct for wild-type and transgenic plants at both Zn exposures. Ethylene was also suggested as an important factor in a pathway induced in the leaves of transgenic plants by high Zn in the apoplast, which results in the initiation of loading of the excess Zn into the mesophyll of "Zn accumulating cells".
Answer: In transgenic tomato plants, the export activity of ectopically expressed AtHMA4 changes the cellular Zn status, which induces coordinated tissue-specific responses of endogenous ethylene-related genes and metal transporters. These changes constitute an important mechanism involved in the generation of the metal-related phenotype of transgenic tomato expressing AtHMA4.

Answer: Does engineering high Zn in tomato shoot through expression of AtHMA4 involves tissue-specific modification of endogenous genes?


Question: Context: Anxiety a core feature of panic disorder, is linked to function of the amygdala. Volume alterations in the brain of patients with panic disorder have previously been reported, but there has been no report of amygdala volume association with anxiety.', 'Volumes of hippocampus and amygdala were manually measured using magnetic resonance imaging obtained from 27 patients with panic disorder and 30 healthy comparison subjects. In addition the amygdala was focused on, applying small volume correction to optimized voxel-based morphometry (VBM). State-Trait Anxiety Inventory and the NEO Personality Inventory Revised were also used to evaluate anxiety.', 'Amygdala volumes in both hemispheres were significantly smaller in patients with panic disorder compared with control subjects (left: t = -2.248, d.f. = 55, P = 0.029; right: t = -2.892, d.f. = 55, P = 0.005). VBM showed that structural alteration in the panic disorder group occurred on the corticomedial nuclear group within the right amygdala (coordinates [x,y,z (mm)]: [26,-6,-16], Z score = 3.92, family-wise error-corrected P = 0.002). The state anxiety was negatively correlated with the left amygdala volume in patients with panic disorder (r = -0.545, P = 0.016).
Answer: These findings suggested that the smaller volume of the amygdala may be associated with anxiety in panic disorder. Of note, the smaller subregion in the amygdala estimated on VBM could correspond to the corticomedial nuclear group including the central nucleus, which may play a crucial role in panic attack.

Answer: Is smaller amygdala associated with anxiety in patients with panic disorder?


Question: Context: This study assessed the association between first-trimester abdominal adiposity and dysglycemia and gestational diabetes mellitus (GDM) in midpregnancy.', "In a prospective cohort of 485 women, we measured subcutaneous (SAT), visceral (VAT), and total (TAT) adipose tissue depth, using ultrasound at 11-14 weeks' gestation. Logistic regression analysis assessed the relation between quartiles of SAT, VAT, or TAT depth and the composite outcome of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or GDM, based on a 75-g oral glucose tolerance test at 24-28 weeks.", 'Adjusting for maternal age, ethnicity, family history of diabetes, and BMI, quartile 4 versus quartile 1 VAT (adjusted odds ratio [aOR] 3.1, 95% CI 1.1-9.5) and TAT (aOR 2.7, 95% CI 1.1-7.8) were significantly associated with the composite outcome, but SAT was not (aOR 1.8, 95% CI 0.70-4.8). The same was seen for GDM alone.
Answer: Elevated first-trimester VAT and TAT depth independently predicted the risk of dysglycemia later in pregnancy.

Answer:
Does first-Trimester Maternal Abdominal Adiposity predict Dysglycemia and Gestational Diabetes Mellitus in Midpregnancy?
