S-1 and CPT-11 plus ramucirumab (IRIS+Rmab) as second-line chemotherapy for patients with oxaliplatin-refractory metastatic colorectal cancer: A multicenter phase II study in Japan (N-DOCC-F-C-1701)

ABSTRACT: Interventions: Treatment by IRIS+Rmab Ramucirumab at a dose of 10mg/kg was administered as a 120-min infusion and irinotecan at a dose of 150mg/m2 by adjustment by UGT1A1 was administered as a 90-min infusion every 3 weeks. The dose of S-1 was determined according to the patient’s body surface area (BSA). Specifically, the drug was administered orally twice daily for 14 consecutive days at a dose that did not exceed 40 mg/m2 based on BSA as follows-BSA<1.25m2, 40 mg; BSA 1.25-1.5 m2, 50mg twice daily; and BSA >1.5 m2, 60 mg by adjustment of Ccr. Premedication with a 5-HT3 antagonist combined with dexamethasone (+/-) an NK-1 antagonist was recommended in patients before the administration of irinotecan. This treatment was administered until disease progression, unacceptable toxicity, withdrawal of consent, or the physician’s decision to terminate treatment. Primary outcome(s): progrssion free survival (PFS) Study Design: Single arm Non-randomized

Genome-wide DNA Microarray Analysis Unravels Rapid Changes in the Transcriptome of MK-801 treated Rat Brain

Project description:N-Methyl-D-aspartate receptors (NMDAr), widely located around the central nervous system, are known to be involved in behavioral disorders. Dizocilpine (commonly referred to as MK-801) is a well known non-competitive NMDAr antagonist. We treated rats with intraperitoneal injection [0.08 (low-dose) and 0.16 (high-dose) mg/kg] of MK-801. In one experiment, 40 min after NaCl (vehicle control) and MK-801 (0.08 mg/kg) injection, electrocorticogram (ECoG) signals were analyzed. In the second experiment, 40 min post-injection, the whole brain of each animal was rapidly removed and separated into amyglada, cerebral cortex, hippocampus, hypothalamus, midbrain and ventral striatum) on ice, followed by analysis using a 4x44K DNA microarray chip. Spectral analysis revealed that a single systemic injection of MK-801 significantly and selectively augmented the power of baseline (30-80 Hz) frequency oscillations. DNA microarray analysis showed the largest number (up- and down- regulations) of gene expressions in the cerebral cortex (378), midbrain (376), hippocampus (375), ventral striatum (353), amygdala (301), and hypothalamus (201) under low-dose of MK-801. Under high-dose, ventral striatum (811) showed the largest number of gene expression changes. Gene expression changes were functionally categorized to reveal expression of genes and function varies with each brain region. MK-801 increases the synchrony of baseline oscillations, causing very early changes in gene expressions in rat brain after acute MK-801 treatment, a first report.

Results: Spectral analysis revealed that a single subcutaneous injection of MK-801 significantly and selectively augmented the power of spontaneous gamma and higher-frequency oscillations. The results from DNA microarray analysis of 4400 genes showed the largest number (up- and down- regulations) of gene expressions in the cerebral cortex (378), midbrain (376), hippocampus (375), ventral striatum (353), amygdala (301), and hypothalamus (201) under low-dose of MK-801.

Data independent acquisition mass spectrometry (DIA-MS) analysis of FFPE rectal cancer samples offers in depth proteomics characterization of response to neoadjuvant chemoradiotherapy

Project description:A total of 97 LARC patients treated at the Institute for Oncology and Radiology of Serbia in the period of 2018-2019 were included in the study. Patients were treated with long-course chemoradiotherapy (CRT): Radiotherapy (RT) was delivered with a total dose of 50.4 Gy in 28 fractions; concomitant chemotherapy (5-FU, 350 mg/m2 daily) and Leucovorin (25 mg/m2 daily) was administered during the first and the fifth week of RT. Patients were evaluated in week 6-8 after treatment completion with pelvic MRI scan and rigid proctoscopy. Pathohistological response after surgery was assessed according to tumor regression grading (TRG) categories by Mandard. Twenty biopsy samples taken at diagnosis were used for proteomic analysis, 9 responders (R, TRG 1-2), and 11 non-responders (NR, TRG 3-5), in order to achieve the maximum range of different molecular features potentially associated with response.

Kraan199_Kinetics of Cortisol Metabolism and Excretion.

Project description:A new model is proposed to study the kinetics of [3H]cortisol metabolism by using urinary data only. The model consists of 5 pools, in which changes of the fractions of dose are given by a system of 5 ordinary differential equations. After i.v. administration of [3H]cortisol to 8 multiple pituitary deficient (MPD) patients (group I) the urines from each patient were collected in 9-15 portions during the following 3 days. From the urinary data the rate constants of cortisol metabolism were calculated. A published set of urinary data from patients with a normal cortisol metabolism (group II) was used for comparison. The overall half-life of the label in the circulation was 30 min for both groups; the half-life of the label excretion by both groups was 6 h and the time of maximal activity in the main metabolizing pool was 1.8 h in group I and 1.5 h in group II. The 20% of normal cortisol production rate (CPR) in the 8 MPD patients amounted to 7.2 + 1.9/zmol/(m2*d). Therefore, the low CPR but normal rate constants, i.e. a normal metabolic clearance rate of cortisol, in the MPD patients suggest a sensitive adjustment of the cortisol response in the target organs.

Effect of insulin infusion on human skeletal muscle

Project description:To identify insulin responsive genes in humans, in the first protocol, skeletal muscle biopsies from six non-diabetic subjects were obtained before and after a two-hour of hyperinsulinaemic (infusion rate 40 mU/m2/min) euglycemic clamp. A variable infusion of glucose (180 g/l) enriched with tritiated glucose (100 μCi/500 ml) maintained euglycemia during insulin infusion, with monitoring of plasma glucose concentration every 5 to 10 min during the basal and clamp periods using an automated glucose oxidation method (Glucose Analyzer 2, Beckman Instruments, Fullerton, CA). In the second protocol, skeletal muscle biopsies from six non-diabetic subjects were obtained before and after a 3-hour hyperinsulinemic (infusion rate 40 mU/m2/min) euglycemic clamp in order to increase the effects of insulin on gene expression. A variable infusion of glucose (180 g/l) was used to maintain euglycemia during insulin infusion with monitoring of plasma glucose concentration every 5 to 10 min using an automated glucose oxidation method (Glucose Analyzer 2, Beckman Instruments, Fullerton, CA). Keywords: dose response The muscle biopsies were obtained from the vastus lateralis muscle under local anesthesia before and after hyperinsulinaemic (infusion rate 40 mU/m2/min) euglycemic clamp

miRNome changes in the mouse kidney, LPS-administered vs. control

Project description:Comparing control and LPS-administered with either 40 mg/kg LPS for early time points (ETP) or 10 mg/kg for late time points (LTP). In ETP, 7-7 animals were sacrificed at 1.5 and at 6 hours after LPS administration. In LTP, 7-7 animals were sacrificed at 24 and 48 hours after the endotoxin injection. In both ETP and LTP 7 mice were received equal volume of saline to use as negative control. Four animals were selected for miRNA microArray analysis based on their proinflammatory (TNF-α and IL-6) mRNA expression levels.

Target deconvolution in Plasmodium falciparum using pulldowns

Project description:Parasite lysates were centrifuged (20,000 g, 4°C, 15 min). Beads (blank and with linker attached) were washed 3× with water then twice with lysis buffer. The lysate (~2 mg total protein) was first incubated with 2 mg blank beads for 30 min at 4°C with rotating agitation. The lysate was divided into two then incubated with either 1% DMSO or 100 µM DDD01510706 (competitor) for 30 min at 4°C with agitation. Finally, lysates were incubated with 2 mg of compound-bound beads for 1 h at 4°C with agitation. The beads were then washed 3× with wash buffer (0.8% (w/v) octyl β-D-glucopyranoside, 50 mM Tris pH 8.0, 5 mM EDTA, 1 mg/mL BSA) and 2× Tris-buffered saline (TBS; 50 mM Tris-Cl pH 7.5, 150 mM NaCl). Samples were run 1.5 cm into a Bis-Tris 10% (w/v) acrylamide gel and stained with Coomassie quick reagent for 30 min. The entire gel bands were removed and subjected to in-gel reduction with 10 mM dithiothreitol, alkylation with 50 mM iodoacetamide and digestion with 12.5 μg/mL trypsin (Pierce) for >16 h at 37°C. Recovered tryptic peptides were then vacuum dried prior to analysis
