VP and Head of Genome Analytics & Bioinformatics, Centre for Genomics Research, Discovery Sciences, R&D. About. We have previously shown that growth hormone (GH) overexpression in the brain increased food intake, accompanied with increased hypothalamic agouti-related protein (AgRP) expression. Central injection of ghrelin into the third dorsal ventricle increased food consumption in +/+ mice, whereas no change was observed in GHR-/- mice. 1,398. Here we describe the discovery and optimization of a small molecule agonist and initial docking studies of this ligand into the receptor in order to provide a suitable lead and tool compound for the elucidation of the physiological function of the receptor. PTH's interaction with the N-terminal domain of PTH1 is mediated in part by Arg-20 on the peptide which forms a number of interactions with the receptor: a charge-charge interaction with Asp-137; hydrogen bonds with the backbone of Asp-29 and Met-32; and hydrophobic interactions with Met-32 and Gln-37.

At AstraZeneca, we are deploying AI across the … In summary, ghrelin's acute central action to increase food intake requires functionally intact GHR signaling. The acute reduction in locomotor activity was observed after only 3-5 h on WD. Long-term GHR deficiency in mice is associated with high plasma leptin levels, obesity, and increased food intake but a marked decrease in all lipoprotein fractions.

Here it’s possible to get immediate feedback from projects and see the methods provide value. WD for only 24 h resulted in a marked physiological shift in energy homeostasis, including increased body weight gain, body fat, and energy expenditure (EE) but an acutely lowered locomotor activity. Our pioneering research identifies novel pathways through which the microbiome can impact outcomes … There is a wide literature that describes HTS and fragment based screening approaches which offer clear direction on the process for these two distinct activities. Reads . AstraZeneca provides this link as a service to website visitors. Granta Park, Cambridge . 1,978 . Thus, we provide the first evidence that long-term central NMU treatment reduces body weight, food intake, and adiposity and that central NMUR2 signaling is required for these effects in female but not male mice. 1,389. The pharmaceutical industry has historically relied on high throughput screening as a cornerstone to identify chemical equity for drug discovery projects. However, these parameters were unaffected by NMU treatment in lean male and female C57BL/6 mice fed a standard diet. Both types of artefact can lead to inaccurate and misleading data.

In contrast, the locomotor activity was reduced and body weight gain was increased over the entire 21-day study period on WD. Our commitment to science is reflected in our track record of publications. These one-step reagents enable the user to go straight from a cellular assay format to qPCR without the need for cumbersome and potentially expensive multistep RNA purification protocols. Ghrelin, which stimulates both appetite and GH secretion, was injected intracerebroventricularly to GHR-/- and littermate control (+/+) mice to determine whether ghrelin's acute effects on appetite are dependent on GHR signaling. One area of significant investment is … AstraZeneca Discovery Sciences. 8 Drug Safety and Metabolism, IMED Biotech Unit, AstraZeneca, 35 Gatehouse Drive, Waltham, Massachusetts 02451, USA. Discovery Sciences. The substitution of Arg-20 with norleucine resulted in a 50-fold reduction in potency at PTH1 and Asp-137-Glu while, in contrast, both Asp-137-Asn and Asp-137-Ala receptors were largely insensitive to this ligand modification. 33.

Calculations based on the correlation between locomotor activity and EE in 2-h intervals at days 21-23 indicated that a large portion of the higher body weight gain in the WD group could be attributed to the reduced locomotor activity. This loss of activity of cytochrome 1A2 could be restored by the use of secondary blocking proteins although changes in the pharmacology of known 1A2 inhibitors were observed.
