Relaxin-3/insulin-like peptide 5 chimeric peptide, a selective ligand for G protein-coupled receptor (GPCR)135 and GPCR142 over leucine-rich repeat-containing G protein-coupled receptor 7.
Relaxin-3, the most recently identified member of relaxin/insulin family, is an agonist for leucine-rich repeat-containing G protein-coupled receptor (LGR)7, GPCR135, and GPCR142. LGR7 can be pharmacologically differentiated from GPCR135 and GPCR142 by its high affinity for relaxin. Selective ligands that specifically activate GPCR135 or GPCR142 are highly desirable for studying their functiona...
متن کاملPharmacological characterization of relaxin-3/INSL7 receptors GPCR135 and GPCR142 from different mammalian species.
Relaxin-3 has recently been identified as a ligand for two structurally related G-protein-coupled receptors, human GPCR135 and GPCR142. This current study reports the characterization of mouse and rat GPCR135 as well as GPCR142 from mouse, monkey, cow, and pig at the molecular and pharmacological levels. Mouse and rat GPCR135 exhibit high homology (>85%) to the human GPCR135 and have very simil...
متن کاملIdentification of relaxin-3/INSL7 as a ligand for GPCR142.
We have recently identified the insulin-like peptide relaxin-3 (aka INSL7) as the endogenous ligand for an orphan G-protein-coupled receptor, GPCR135 (aka somatostatin- and angiotensin-like peptide receptor). Analysis of possible receptors related to GPCR135 revealed a single orphan receptor, GPCR142. Thus, we tested whether GPCR142 could also respond to relaxin-3 or related insulin-like molecu...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
