Effects of attenuating astrocytic Ca2+ activity in the medial prefrontal cortex with iβARK on transcriptional profiles in wild-type mice.

ABSTRACT: We injected adeno-associated viruses (AAV2/5) carrying an inhibitory peptide derived from β-adrenergic receptor kinase 1 (iβARK), tagged with mCherry for visualization, into the medial prefrontal cortex (mPFC) of wild-type mice. This approach selectively attenuated Gq-coupled GPCR-induced Ca²⁺ activity in astrocytes. Control mice received AAV2/5 expressing mCherry alone. Subsequently, we performed RNA sequencing on mPFC tissue samples to compare transcriptomic profiles and investigate the potential functional consequences of perturbing Gq-GPCR signaling.

Effects of attenuating astrocytic Ca2+ activity in the medial prefrontal cortex with iβARK on transcriptional profiles in 5xFAD mice

Project description:We injected adeno-associated viruses (AAV2/5) carrying an inhibitory peptide derived from β-adrenergic receptor kinase 1 (iβARK), tagged with mCherry for identification, into the medial prefrontal cortex (mPFC) of 5xFAD mice. This strategy aimed to attenuate Gq GPCR-induced Ca2+ activity in astrocytes. In the control group, mice were injected with AAV2/5 expressing only mCherry. Subsequently, RNA sequencing analysis was conducted on the mPFC tissue samples from these mice, enabling a comparative assessment of transcriptomic alterations and an exploration of the potential implications resulting from the modulation of Gq-GPCR signaling.

PKCzeta-mediated Gaq stimulation of the ERK5 pathway is involved in cardiac hypertrophy

Project description:Background: Gq-coupled G protein-coupled receptors (GPCR) mediate the actions of a variety of messengers that are key regulators of cardiovascular function. Enhanced Gaq-mediated signaling plays an important role in cardiac hypertrophy and in the transition to heart failure. We have recently described that Gaq acts as an adaptor protein that facilitates PKCz-mediated activation of ERK5 in epithelial cells. Since the ERK5 cascade is known to be involved in cardiac hypertrophy, we have investigated the potential relevance of this pathway in Gq-dependent signaling in cardiac cells. Methodology/Principal Findings: We have explored the mechanisms involved in Gq-coupled GPCR-mediated stimulation of the ERK5 pathway and its functional consequences in cardiac hypertrophy using both cultured cardiac cells and an animal model of angiotensin- dependent induction of cardiac hypertrophy in wild-type and PKCz knockout mice. We find that PKC? is required for the activation of the ERK5 pathway by Gq-coupled GPCR in cardiomyocytes and in cardiac fibroblasts. Stimulation of ERK5 by angiotensin II is blocked upon pharmacological inhibition or siRNA-mediated silencing of PKCz in primary cultures of cardiac cells and in cardiomyocytes isolated from PKCz-deficient mice. Moreover, these mice do not develop cardiac hypertrophy upon chronic challenge with angiotensin II, as assessed by morphological, biomarker, electrocardiographic and global gene expression pattern analysis. Conclusion/Significance: Our data put forward that PKC? is essential for Gq- dependent ERK5 activation in cardiac cells and indicate a key cardiac physiological role for this recently described Gaq/PKCz/MEK5 signaling axis. Littermate wild-type and PKCz -/- male mice (32 weeks of age) were subjected to continuous infusion of angiotensin II (or PBS as a control) for 14 days, a well established model for the induction of cardiac hypertrohy

Specific and behaviorally consequential astrocyte G q GPCR signaling attenuation in vivo with iβARK

Project description:The Khakh laboratory used astrocyte selective AAVs expressing Rpl22-HA along with bARK for attenuating Gq pathway signaling in the dorsal striatum. In the control group, bARK(D110A), which is a mutated control of bARK was expressed instead of bARK. The mouse striatum expressing either bARK or bARK(D110A) was subjected to RNA-seq in order to compare striatal astrocyte transcriptomes with and without Gq-GPCR signaling attenuation.

Transcription profile of aging and cognitive-related genes in the medial prefrontal cortex and hippocampal region CA1

Project description:This study focused on transcription in the medial PFC (mPFC) as a function of age and cognition. Young and aged F344 rats were characterized on tasks, attentional set shift and spatial memory, which depend on the mPFC and hippocampus, respectively. Differences in transcription associated with age and cognitive function were examined using RNA sequencing to construct transcriptomic profiles for the mPFC, white matter, and region CA1 of the hippocampus. The results indicate regional differences in vulnerability to aging associated with increased expression of immune and defense response genes and a decline in synaptic and neural activity genes. Importantly, we provide evidence for region specific transcription related to behavior. In particular, expression of transcriptional regulators and neural activity-related immediate-early genes (IEGs) are increased in the mPFC of aged animals that exhibit delayed set shift behavior; relative to age-matched animals that exhibit set shift behavior similar to younger animals. The study contains 11 young and 20 aged rats for the mPFC and CA1 samples, which were used to investigate expression patterns associated with aging and behavior. White matter samples were used to investigate an age-related effect with 8 young and 9 aged rats.

Proteomic profiling of astrocytic O-GlcNAc transferase related proteins in the mPFC

Project description:Our research showed that astrocytic OGT could influence the expression of proteins in the mPFC. Most of these altered proteins participate in metabolic process, transferase activity, and biosynthetic process. GFAP, an astrocyte maker, was increased after OGT deletion. These results provide a framework for further study on the role of astrocytic OGT/O-GlcNAcylation in the mPFC.

Transcriptome Analysis of the Mouse Medial Prefrontal Cortex in Chronic Constriction Injury Model

Project description:The medial prefrontal cortex (mPFC) is critical for both the sensory and emotional /cognitive components of pain. However, the underlying mechanism still remains largely unknown. Here, we examined changes in the transciptomic profiles in the mPFC of mice with chronic pain using RNA sequencing (RNA-seq) technology. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different group of mPFC from mice, including ipsilateral part (Left side, the same to our operation part) of mPFC, contralateral part (Right side, opposite to our operation part) of mPFC after CCI (Chronic Constriction Injury of Sciatic Nerve) operation. Combining with naïve mice, at 28 days after operation.
