Project description:The phytohormone GA controls multiple important developmental processes in plants such as germination, elongation growth and flowering time. In this experiment, we look for early GA response genes in 7 day-old light-grown Arabidopsis seedlings. To this end we compare four data sets: (1) a GA biosynthesis mutant ga-1 (SALK_109115) mock treated for 1 hr; (2) a GA biosynthesis mutant ga-1 (SALK_109115) treated for 1 hr with 100 µM GA3; (3) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant mock treated for 1 hr; (4) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant treated for 1 hr with 100 µM GA3. In a comparison of the two ga-1 samples, GA regulated genes can be identified, and the assumption is that bona fide GA regulated genes are not responding in the gid1a-1 gid1b-1 gid1c-2 GA receptor mutant.

Project description:Mice (n=85) were anaesthetised by ip injection (0.1 ml/10 g) of xylazine (5%) and ketamine (10%) diluted in sterile water. After placing animals in a stereotactic frame, the skull surface was exposed and holes were drilled at the appropriate sites to allow bilateral infusion of ibotenic acid (10 ï¾µg/ï¾µl in saline) with a glass capillary (40 ï¾µm external tip) glued to a 1 ï¾µl Hamilton syringe connected to stereotactic syringe pump (KDS 310, KD scientific). Antero-posterior (AP), lateral (L) and vertical (V) coordinates (in mm) for micro-infusions in the dorsal hippocampus, were taken relative to the bregma: (1) AP -1.7, L +/- 1, V -1.5; (2) (2) AP -2.2, L +/- 1.5, V -1.5; (3) AP -2.6, L+/- 2, V -1.5 (based on brain atlas by Paxinos and Franklin, 2004). The infused volume of ibotenic acid or PBS was 30 nl per injection site. The rate of infusion was 30 nl/min and the needle was left in situ for another 2 min, before being slowly retracted.

Project description:Activity-dependent neuroprotective protein (ADNP) syndrome is a rare neurodevelopmental disorder caused by mutations in the ADNP gene, resulting in intellectual disability, developmental delay and autism spectrum disorder (ASD). Ketamine treatment has emerged as a promising therapeutic option for children with ADNP syndrome, showing safety and significant behavioral improvements. However, the underlying molecular perturbations caused by ketamine remain poorly described. We dissected the longitudinal effect of ketamine on the peripheral blood transcriptome of 10 individuals with ADNP syndrome. The blood transcriptome was profiled prior-to intravenous ketamine treatment (0.5mg/kg) and then again at five post-infusion timepoints: immediately post-infusion, day 1, week 1, week 2, and week 4. We show that a single low-dose infusion of ketamine triggers immediate and profound gene expression alterations, with specific enrichment of monocyte-related expression patterns. These alterations encompass diverse signaling pathways and co-expression networks, implicating up-regulation of immune and inflammatory-related processes and down-regulation of RNA processing mechanisms and metabolism. Notably, these changes exhibit a transient nature, returning to baseline levels 24 hours to 1 week after treatment. These findings advance our understanding of ketamine's molecular effects and provides a foundation for further research in elucidating its precise cellular and molecular targets. Moreover, the comprehensive assessment of ketamine-induced changes in ADNP syndrome contributes to the development of innovative therapeutic strategies for this challenging genetic disorder.

Project description:Animals. Male Sprague–Dawley rats (Charles River Laboratories, Wilmington, MA) weighing about 250g were used. The study was approved by the Thomas Jefferson University Institutional Animal Care and Use Committee and was conducted in accordance with the National Institutes of Health Guide for the Care and Use of Laboratory Animals. The animals were housed in Thomas Jefferson University's animal care facilities. Animals were anesthetized with isoflurane dissolved in O2 (5% induction; 1% maintenance) and one femoral artery and vein were cannulated (PE-50 tubing) via a small medial incision for measurement of arterial pressure and infusion of drugs, respectively. The cannulae were run subcutaneously to an exit incision between the scapulae. The leg wound was sutured and topical anesthetic (lidocaine) was applied to both skin incisions. Following surgery, after one hour of stable and normal resting blood pressure and heart rate, intravenous infusion was initiated of approximately 1 mL saline, as a control, or phenylephrine (200 µg/mL; 1 mL/hr), to induce hypertension. We followed standard methods in the use of phenylephrine (PE) to elevate blood pressure. PE does not cross the blood brain barrier and the elevated blood pressure it produces has been shown to cause molecular effects in the NTS principally via increased baroreceptor afferent drive by both pharmacological and sinoaortic denervation studies. We titered the PE dose to maintain intermediate levels of elevated blood pressure 25 mmHg above resting blood pressure. Keywords: Hypertension, time series

Project description:Clinical studies have shown that IV administration of anesthetics, lidocaine and ketamine with their anti-inflammatory properties, modulates the acute immune response associated with surgical tissue injury, and in this manner they are able to reduce postoperative pain. Lidocaine has anti-inflammatory effects on polymorphonuclear granulocytes, IL-6 and IL-8 cytokines, complement component C3a and IL-1ra in serum. Ketamine produces its anti-inflammatory effects by reducing CRP and IL-6 in serum and by inhibiting NF-kB, which regulates gene transcription responsible for the production of proinflammatory factors.
Perioperative combinend IV administration of lidocaine and ketamine could have a more favorable anti-inflammatory effect compared to anesthetic given alone or with placebo.
To investigate the effects of lidocaine and ketamine in patients undergoing abdominal surgery on: acute immune response following the level of proinflammatory factors in serum (CRP, IL-6, IL-8); postoperative pain management; recovery of bowel function; administration of opioids; reduction of total treatment costs; length of hospital stay (LOHS)
A double-blind, placebo-controlled study will include 100 patients undergoing open colorectal surgery. Patients will be randomly assigned to one of four groups: lidocaine, ketamine, lidocaine-ketamine, and placebo. Lidocaine will be administered at a dose of 1.5 mg/kg prior to surgical incision followed by an infusion at a rate of 1.5-2 mg/kg/hr until the end of surgery. Ketamine will be administered at a dose of 0.5 mg/kg in a bolus prior to surgical incision followed by an infusion at a rate of 0.1-0.2 mg/kg/hr until the end of surgery. Bolus and continuous placebo infusion (0.9% NaCl) will be equally administered at the same dose as the aforementioned anesthetics until the end of the surgery.
Proinflammatory markers in serum (CRP, IL-6, IL-8) will be measured before induction of anesthesia, then 12 hours and 36 hours following the completion of surgery. The intensity of pain will be measured using the VAS score 2 hours and 4 hours following surgery and every 12 hours the following days. The investigators will measure also the consumption of opioids during and after surgery, the length of stay in the ICU, where pain control and analgesics use will be measured, as well as recovery of bowel function.

Project description:In the current study, we compared phosphoproteomic and proteomic changes in roots of different soybean seedlings of a salt-tolerant cultivar (Wenfeng07) and a salt-sensitive cultivar (Union85140) induced by salt stress. The root samples of Wenfeng07 and Union85140 at three-trifoliate stage were collected at 0 hr, 0.5 hr, 1 hr, 4 hrs, 12 hrs, 24 hrs and 48 hrs after been treated with 150 mM NaCl. LC-MS/MS based phosphoproteomic analysis of these samples identified a total of 2692 phosphoproteins and 5509 phosphorylation sites. Of these, 2344 phosphoproteins containing 3744 phosphorylation sites were quantitatively analyzed. Our results showed that 1163 phosphorylation sites were differentially phosphorylated in the two compared cultivars.
