Zhuo X, Wu Y, Yang Y, Gao L, Qiao X, Chen T (2019) LncRNA AK094457 promotes AngII-mediated hypertension and endothelial dysfunction through suppressing of activation of PPARγ. Life Sci 233:116745. doi: 10.1016/j.lfs.2019.116745 PMID: 31404524

Objective: To find the functional lncRNAs associated with hypertension, high throughput lncRNA microarray were used to analyze expression profile of the lncRNAs in the aortic vascular endothelial cells of spontaneously hypertensive rats.

Summary: lncRNA AK094457 is identified as a key regulator in blood pressure and endothelial function, which can increase AngII-induced hypertension and endothelial dysfunction via suppression of PPARγ.

Usage: Western Blot (1:500), immunohistochemistry

Ladd MR, Costello CM, Gosztyla C, Werts AD, Johnson B, Fulton WB, Martin LY, Redfield EJ, Crawford B, Panaparambil R, Sodhi CP, March JC, Hackam DJ (2019) Development of intestinal scaffolds that mimic native mammalian intestinal tissue. Tissue Eng Part A 25(17-18):1225-1241. doi: 10.1089/ten.TEA.2018.0239 PMID: 30652526

Objective: To develop a scaffold for the generation of an artificial intestine that specifically mimics the architecture and biomechanical properties of the native small intestine, and to evaluate the scaffold in vitro and in vivo.

Summary: Novel scaffolds were developed using PGS with promise for use in artificial intestine for individuals with short bowel syndrome.

Usage: Histology, immunohistochemistry, microscopy (1:500)

Objective: To investigate whether enhanced activation of the patch compartment contributes to habitual behavior.

Summary: The dorsolateral patch compartment may mediate habit formation by altering information flow through basal ganglia circuits.

Usage: A volume of 2 ul of Dermorphin-SAP (17 ng/ul or an equivalent amount of unconjugated SAP (as a control) was infused bilaterally, at a rate of 0.5 ul/min.

Objective: To explore circuitry and potential glucose-sensing mechanisms that contribute to the functions of glucoregulatory catecholamine neurons in the ventrolateral medulla

Summary: Selective lesion of hindbrain catecholamine neurons abolishes glucoprivic elicitation of key counterregulatory responses. Selective chemogenetic activation of specific catecholamine populations elicits these responses.

Soares JI, Da Costa C, Ferreira MH, Andrade PA, Maia GH, Lukoyanov NV (2019) Partial depletion of septohippocampal cholinergic cells reduces seizure susceptibility, but does not mitigate hippocampal neurodegeneration in the kainate model of epilepsy. Brain Res 1717:235-246. doi: 10.1016/j.brainres.2019.04.027

Objective: To examine how the inhibition of epilepsy-related cholinergic plasticity may be reflected in seizure susceptibility and/or in the development of chronic epilepsy and its neurological consequences.

Summary: These data suggest that seizure-induced plasticity of cholinergic cells may indeed enhance seizure susceptibility and contribute to epileptogenic processes. They do not support the hypothesis that epilepsy-related hypertrophy of cholinergic neurons may potentiate hippocampal cell loss and respective behavioral impairments.

Usage: Bilateral lesions of cholinergic cells were made by infusing 0.5 μl of 192-IgG-saporin (0.08 μg/μl saline solution) into the hippocampus.

Objective: To determine the underlying mechanisms that induce high energy intake (EI) per body weight (BW).

Summary: Undeveloped properties of VTA GABA neurons in juvenile rats can promote higher EI regardless of high or less palatable feeding, and contribute to growth promotion.

Usage: GAT1-SAP or control, Rabbit IgG-SAP, was bilaterally injected (0.025 μg/0.5 μl) into the VTA in eight-week-old adult rats.
