Intra-articular injection of 2-pyridylethylamine produces spinal NPY-mediated antinociception in the formalin-induced rat knee-joint pain model
Souza-Silva E, Stein T, Mascarin LZ, Dornelles FN, Bicca MA, Tonussi CR (2020) Intra-articular injection of 2-pyridylethylamine produces spinal NPY-mediated antinociception in the formalin-induced rat knee-joint pain model. Brain Res 1735:146757. doi: 10.1016/j.brainres.2020.146757 PMID: 32135147
Objective: To investigate the participation of spinal NPY in the antinociceptive effect produced by 2-pyridylethylamine (2-PEA).
Summary: These data support the idea that antinociception induced by H1R agonists in the knee-joint of rats may be mediated by the spinal release of NPY, and this peptide seems to be acting via Y1R.
Usage: IT pretreatment with NPY-SAP (750 ng) reduced immunoblotting for Y1R in spinal cord homogenates.

Neuroendocrine and behavioral consequences of hyperglycemia in cancer
Vasquez JH, Borniger JC (2020) Neuroendocrine and behavioral consequences of hyperglycemia in cancer. Endocrinology 161(5):bqaa047. doi: 10.1210/endocr/bqaa047 PMID: 32193527
Summary: Ablation of norepinephrine containing projections to the arcuate (via Anti-DBH-SAP injections) alters AgRP and neuropeptide (NPY) concentrations, leading to impairments in hypoglycemic (glucoprivic) or ghrelin-induced feeding.
Usage: Anti-DBH-SAP (bilateral 42-ng intracranial injections) was used in rats to investigate the role of hindbrain catecholamine afferents in increased ARC NPY and AgRP gene expression.

Loss of leptin receptor-expressing cells in the hindbrain decreases forebrain leptin sensitivity.
Harris RBS (2020) Loss of leptin receptor-expressing cells in the hindbrain decreases forebrain leptin sensitivity. Am J Physiol Endocrinol Metab 318(5):E806-E816. doi: 10.1152/ajpendo.00020.2020
Objective: This study tested whether loss of hindbrain leptin receptor signaling changed sensitivity to forebrain leptin.
Summary: Loss of VMH (ventromedial nucleus of hippocampus) leptin receptor-expressing cells prevents weight loss. The integrated response between the hindbrain and forebrain is heavily dependent upon leptin activity in the VMH.
Usage: To test forebrain leptin sensitivity Leptin-SAP and Blank-SAP rats received third ventricle injections of 0, 0.05, 0.1, 0.25 or 0.5 μg leptin.

Baoyuan decoction ameliorates apoptosis via AT1-CARP signaling pathway in H9C2 cells and heart failure post-acute myocardial infarction rats
Wang X, Meng H, Wang Q, Shao M, Lu W, Chen X, Jiang Y, Li C, Wang Y, Tu P (2020) Baoyuan decoction ameliorates apoptosis via AT1-CARP signaling pathway in H9C2 cells and heart failure post-acute myocardial infarction rats. J Ethnopharmacol 252:112536. doi: 10.1016/j.jep.2019.112536 PMID: 31931161
Objective: To elucidate whether Baoyuan decoction (BYD) ameliorates apoptosis to protect against heart failure via the AT1-Cardiac ankyrin repeat protein (CARP) signaling pathway.
Summary: BYD improves cardiac function and protects against cardiomyocytes injury by inhibiting apoptosis via regulating the AT1-CARP signaling pathway.
Usage: Western blot (1:1000)

The subcortical belly of sleep: New possibilities in neuromodulation of basal ganglia?

Summary: Complete BF lesion with OX-SAP leads to coma-like state and flat EEG, reduced Fos in cerebral cortex (but high Fos in brainstem, thalamus, hypothalamus) selective (cholinergic or non-cholinergic) lesion does not have this effect.
Usage: Lesions of the basal forebrain were done by injecting a 0.1% solution of Orexin-SAP at four different sites.

Objective: To examine the anatomical and functional aspects of zinc in the circadian system.
Summary: Neither enhancement nor chelation of free zinc at either the SCN or IGL altered circadian responses to phase-shifting light in hamsters.
Usage: Retinal immunohistochemistry (1:5000) included a 20-min wash in 4% PFA prior to initiation of the IHC protocol.

Objective: To investigate whether abnormal expression of central wnt/β-catenin signaling and renin-angiotensin system (WNT-RAS signaling) was tightly involved in chronic kidney disease (CKD).
Summary: These data suggest that the central WNT-RAS signaling plays a significant role in the development and progression of CKD.

Ma YP, Yang Y, Jiang SM, Liu L, Zhang Z, Wang YN, Zou GM, Li WG (2020) Angiotensin II type 1 receptor blockers favorably affect renal angiotensin II and MAS receptor expression in patients with diabetic nephropathy. J Renin Angiotensin Aldosterone Syst 21(2):1470320320919607. doi: 10.1177/1470320320919607 PMID: 32370637
Objective: To assess the renal expression of angiotensin II type 1 receptor (AT1R), angiotensin II type 2 receptor (AT2R), and MAS receptor in human type 2 diabetic nephropathy (DN).
